00:01:36,262 --> 00:01:38,481
Welcome to NASA's Kennedy Space Center,
where we are

2
00:01:38,481 --> 00:01:42,569
starting today
with this gorgeous view of Launch Pad 39 B

3
00:01:42,802 --> 00:01:46,706
and on the pad, of course, NASA's Space
Launch System rocket and Orion spacecraft.

4
00:01:46,940 --> 00:01:48,625
NASA is targeting next month

5
00:01:48,625 --> 00:01:53,096
for its earliest opportunities
to launch Artemis two for astronauts

6
00:01:53,096 --> 00:01:57,300
on a journey around the moon
for the first time in more than 50 years.

7
00:01:57,717 --> 00:01:59,569
Good morning,
and thank you for joining us today.

8
00:01:59,569 --> 00:02:02,572
I'm NASA's Megan Cruz,
and you are watching a press conference

9
00:02:02,572 --> 00:02:05,575
to discuss this week's
wet dress rehearsal.

10
00:02:05,875 --> 00:02:09,979
The Artemis two launch team rehearsed,
fueling the rocket again ahead of launch.

11
00:02:09,979 --> 00:02:11,664
And so to discuss how it went

12
00:02:11,664 --> 00:02:15,084
and the road ahead, we have this
distinguished panel for you today.

13
00:02:15,301 --> 00:02:19,172
We have Lori Glaze right next to me
here, NASA's Moon to Mars program

14
00:02:19,172 --> 00:02:24,477
manager and explorer Charlie Blackwell
Thompson, Artemis launch director.

15
00:02:24,861 --> 00:02:29,432
And then finally, John Honeycutt, chair of
the Artemis two mission management team.

16
00:02:29,899 --> 00:02:31,050
Thank you all for being here.

17
00:02:31,050 --> 00:02:32,869
And as always,
we are going to start with some opening

18
00:02:32,869 --> 00:02:35,872
remarks from each of them,
and then we will go to your questions.

19
00:02:35,972 --> 00:02:37,857
So, Lori,
why don't you go ahead and kick us off.

20
00:02:37,857 --> 00:02:39,926
You bet. Thank you Megan.

21
00:02:39,926 --> 00:02:43,880
So it's been just,
I think, a little under three weeks

22
00:02:43,880 --> 00:02:46,883
since we met to discuss
wet dress number one.

23
00:02:47,450 --> 00:02:49,252
So I just want to thank everybody,

24
00:02:49,252 --> 00:02:51,871
who's here in the room
and who's dialed in online.

25
00:02:51,871 --> 00:02:53,640
To listen to the press briefing today.

26
00:02:53,640 --> 00:02:56,809
We're very excited to talk to you about,
how the wet dress went yesterday.

27
00:02:57,443 --> 00:03:01,014
But I want to start first
by thanking our incredible team,

28
00:03:01,064 --> 00:03:04,918
across all parts of the Artemis
two program,

29
00:03:04,918 --> 00:03:07,921
that have gotten us to this point
where we are today.

30
00:03:08,421 --> 00:03:11,958
They have done an enormous amount of work
to get us to this point.

31
00:03:12,208 --> 00:03:15,778
And just over,
as I said, the last three weeks, a little

32
00:03:15,778 --> 00:03:19,799
less than three weeks,
a lot of work, learning from

33
00:03:19,799 --> 00:03:23,937
wet dress one, putting in place
some fixes to things like the seals,

34
00:03:24,420 --> 00:03:28,007
at the quick, disconnect, interface,

35
00:03:29,275 --> 00:03:29,842
doing some

36
00:03:29,842 --> 00:03:34,697
replacement on the filters on the ground
system side, thinking through,

37
00:03:34,697 --> 00:03:38,518
various aspects of how we implement,
the wet dress rehearsal.

38
00:03:38,701 --> 00:03:43,706
And I can say for the most part, those, 
fixes all performed pretty well yesterday.

39
00:03:43,706 --> 00:03:46,709
And Charlie is going to speak to that
in a lot more detail.

40
00:03:46,709 --> 00:03:48,511
So that was really exciting.

41
00:03:48,511 --> 00:03:51,297
I mean, if you followed our progress,
yesterday,

42
00:03:51,297 --> 00:03:55,919
we were able to fully tank the SLS rocket
within the planned timeline.

43
00:03:56,486 --> 00:03:59,689
We demonstrated our crew module
closeout activities

44
00:03:59,689 --> 00:04:02,692
with the closeout crew again
on the timeline.

45
00:04:03,559 --> 00:04:07,280
And we also successfully demonstrated,
the launch clamp down.

46
00:04:07,280 --> 00:04:09,983
And again,
Charlie, we'll talk in a lot more detail.

47
00:04:09,983 --> 00:04:11,668
We did navigate through a few issues.

48
00:04:11,668 --> 00:04:12,352
You'll hear a little bit

49
00:04:12,352 --> 00:04:15,955
about some of those, but overall
the countdown went very, very smoothly.

50
00:04:16,522 --> 00:04:19,792
We do have work to go,
to get our systems

51
00:04:19,792 --> 00:04:21,928
ready for launch,
where we've already begun the day.

52
00:04:21,928 --> 00:04:23,813
Two reviews from the wet dress yesterday.

53
00:04:23,813 --> 00:04:25,465
And there's some other work
that needs to be done.

54
00:04:25,465 --> 00:04:27,216
Out of the pad.

55
00:04:27,216 --> 00:04:32,121
One thing I do want to say here today
is that for, following that successful

56
00:04:32,121 --> 00:04:37,760
wet dress yesterday, we're now targeting
March 6th as our earliest launch attempt.

57
00:04:38,811 --> 00:04:42,181
I am going to
caveat that I want to be open, transparent

58
00:04:42,482 --> 00:04:45,468
with all of you,
that there is still pending work.

59
00:04:46,502 --> 00:04:48,388
There's work a lot of forward work that

60
00:04:48,388 --> 00:04:51,858
remains, including, the post
wet dress analysis.

61
00:04:51,858 --> 00:04:52,942
Of course.

62
00:04:52,942 --> 00:04:56,546
We do have some significant work
to be completed out of the pad, Charlie.

63
00:04:56,546 --> 00:04:58,348
We'll talk to that in more detail.

64
00:04:58,348 --> 00:05:01,200
And we also have a multi-day flight

65
00:05:01,200 --> 00:05:04,187
readiness review
that will come up, later next week.

66
00:05:04,520 --> 00:05:06,539
And so those things
are all in front of us.

67
00:05:06,539 --> 00:05:11,260
We need to successfully navigate
all of those, but assuming that happens,

68
00:05:11,260 --> 00:05:14,630
that it puts us in a very good position,
to target the March 6th.

69
00:05:15,298 --> 00:05:20,303
We were fortunate yesterday
to have several of our crew members

70
00:05:20,303 --> 00:05:22,472
present for the wet dress rehearsal.

71
00:05:22,472 --> 00:05:27,527
I was able to speak a little bit with, wit

72
00:05:28,611 --> 00:05:30,063
Jeremy Hanson.

73
00:05:30,063 --> 00:05:31,581
They're all very, very excited.

74
00:05:31,581 --> 00:05:34,350
I was glad they could be here for
for the wet dress.

75
00:05:34,350 --> 00:05:38,788
They are really getting, 
a lot of anticipation

76
00:05:38,788 --> 00:05:40,707
for a potential launch in March.

77
00:05:40,707 --> 00:05:43,159
And they go into quarantine
this afternoon.

78
00:05:43,159 --> 00:05:44,110
This evening?

79
00:05:44,110 --> 00:05:47,113
So they will begin that quarantine
later today.

80
00:05:48,681 --> 00:05:50,133
The excitement for Artemis

81
00:05:50,133 --> 00:05:53,036
two is really, really starting to build.

82
00:05:53,036 --> 00:05:54,687
We can really start to feel it.

83
00:05:54,687 --> 00:05:56,789
It's it's coming.

84
00:05:56,789 --> 00:05:59,809
And I really can't wait to welcome
you all back here to Kennedy

85
00:05:59,809 --> 00:06:02,962
Space Center when we're ready to fly,
launch and fly this mission.

86
00:06:03,329 --> 00:06:07,650
You know, every night
I, look up at the moon and I see it,

87
00:06:08,334 --> 00:06:09,385
and I get really excited

88
00:06:09,385 --> 00:06:12,538
because I can really feel she's calling
us, and we're ready.

89
00:06:13,373 --> 00:06:15,058
Thank you. I'm
going to hand it over to Charlie.

90
00:06:16,459 --> 00:06:17,160
All right.

91
00:06:17,160 --> 00:06:19,979
Thanks, Laura. Appreciate that.

92
00:06:19,979 --> 00:06:24,200
Well, let's see, since we were here,
Laurie said a little over two weeks ago.

93
00:06:24,267 --> 00:06:26,602
There's been a lot of work out
at the pad.

94
00:06:26,602 --> 00:06:31,441
So since WDR one, as you know,
we had some leaks, in our,

95
00:06:31,591 --> 00:06:33,292
ground to flight interface there.

96
00:06:33,292 --> 00:06:37,313
And we have we went in and we changed
both the eight inch and the four inch seal

97
00:06:37,313 --> 00:06:38,898
in that plate cavity.

98
00:06:38,898 --> 00:06:44,087
I'm happy to report that yesterday,
both of those interfaces were rock solid.

99
00:06:44,087 --> 00:06:46,672
We saw maybe

100
00:06:46,672 --> 00:06:50,209
1% or less, in that eight inch, line

101
00:06:50,209 --> 00:06:54,414
in that interface, 
which is, is really solid.

102
00:06:54,647 --> 00:06:56,966
And then, and actually
it was a little less than that.

103
00:06:56,966 --> 00:06:59,969
And then about 1.5% in the four inch. So

104
00:07:01,220 --> 00:07:03,389
really no leakage to speak of.

105
00:07:03,389 --> 00:07:06,025
So it was really performed well.

106
00:07:06,025 --> 00:07:08,778
So the work that the team did paid off.

107
00:07:08,778 --> 00:07:14,150
You know, we did a hydrogen integrity
test, before we went back to wet dress.

108
00:07:14,150 --> 00:07:17,820
We felt that that was important to get
a little understanding of that interface

109
00:07:17,820 --> 00:07:22,074
before we brought the entire vehicle up
and tank both stages in both commodities.

110
00:07:22,525 --> 00:07:26,162
So we got a little bit of data
out of that that helped us pinpoint that.

111
00:07:26,162 --> 00:07:29,482
We believe the leak source was primarily
from our eight inch seal.

112
00:07:30,183 --> 00:07:32,718
We changed them both, though,

113
00:07:32,718 --> 00:07:35,721
because we were in there
and it just made sense to go do that.

114
00:07:36,038 --> 00:07:38,207
Yesterday we got into tanking.

115
00:07:38,207 --> 00:07:38,958
We gave the go

116
00:07:38,958 --> 00:07:42,812
for tanking at 928 in the morning,
so we were a little bit ahead of schedule.

117
00:07:42,812 --> 00:07:46,048
Of course, the call to stations
was the night before powered up

118
00:07:46,048 --> 00:07:49,852
the vehicle elements got everything
configured, got into all of our preps.

119
00:07:49,852 --> 00:07:52,855
We were ready for load yesterday morning.

120
00:07:52,872 --> 00:07:54,891
Gave the go for that.

121
00:07:54,891 --> 00:07:59,362
We did make a couple changes to our wet
dress count down from wet dress

122
00:07:59,362 --> 00:07:59,962
number one.

123
00:07:59,962 --> 00:08:03,983
We added a little extra time,
into the hole before tanking.

124
00:08:03,983 --> 00:08:07,136
And then in the hold after tanking
and we did that.

125
00:08:07,136 --> 00:08:10,189
In the event that we ran into an issue,
we know that

126
00:08:10,523 --> 00:08:14,460
it takes about 20 to 30 minutes
to run that contingency scenario,

127
00:08:14,460 --> 00:08:17,446
where we left the queue to warm up
and we're it fell.

128
00:08:18,331 --> 00:08:20,850
So we want to have
a little bit of extra time.

129
00:08:20,850 --> 00:08:22,552
Thankfully, we didn't need it for that.

130
00:08:24,020 --> 00:08:25,171
But overall,

131
00:08:25,171 --> 00:08:28,157
the the test went through the tanking.

132
00:08:28,307 --> 00:08:31,944
It was it was really quiet
and and went well,

133
00:08:31,994 --> 00:08:35,364
we did experience
an issue with our comm system.

134
00:08:35,364 --> 00:08:37,667
That was probably the most exciting thing

135
00:08:37,667 --> 00:08:41,521
that happened during the tanking scenario,
but it wasn't related to the loading

136
00:08:41,521 --> 00:08:43,489
of cryogenic commodities.

137
00:08:43,489 --> 00:08:46,192
We didn't have the flight crew
participating.

138
00:08:46,192 --> 00:08:49,579
We had them observing but
not participating actively in the tests.

139
00:08:49,579 --> 00:08:50,997
In other words,
they didn't go out to the pad,

140
00:08:50,997 --> 00:08:54,000
but we did send the close up
crew out to the pad.

141
00:08:54,200 --> 00:08:58,788
And, they went through their timeline,
their normal clothes out of the Orion crew

142
00:08:58,788 --> 00:09:03,292
module, the last hatch and the white room,
all of that went part of the timelines.

143
00:09:03,292 --> 00:09:07,113
And, and then we got into
our terminal part of count.

144
00:09:07,496 --> 00:09:11,000
We resumed from our count at, at 832,

145
00:09:11,033 --> 00:09:14,453
we were targeted an 830 t0 initial t0.

146
00:09:15,054 --> 00:09:17,957
We were a little bit, behind that
coming out.

147
00:09:17,957 --> 00:09:21,661
But again,
really close to the opening of the window,

148
00:09:22,461 --> 00:09:24,747
we had a, planned hold.

149
00:09:24,747 --> 00:09:29,068
We were going to demonstrate
that three minute, nine hole constraint.

150
00:09:29,068 --> 00:09:30,386
We have never done that before.

151
00:09:30,386 --> 00:09:33,889
We did that yesterday,
and we were successful in doing so.

152
00:09:34,223 --> 00:09:38,427
We held the clock at a minute 30,
for the three minutes we picked up,

153
00:09:38,427 --> 00:09:40,997
we actually went a little bit over
the three minutes we picked up

154
00:09:40,997 --> 00:09:44,550
and we counted down,
and then we had a planned cut off,

155
00:09:44,550 --> 00:09:46,102
and we went through our recycle

156
00:09:46,102 --> 00:09:49,171
with the flight hardware,
with a cryogenically fueled vehicle.

157
00:09:49,171 --> 00:09:51,774
Again, first time we've ever done that.

158
00:09:51,774 --> 00:09:53,009
Validate in our timelines.

159
00:09:53,009 --> 00:09:55,378
We expected it to take about an hour
a little over.

160
00:09:55,378 --> 00:09:57,229
We did in 57 minutes.

161
00:09:57,229 --> 00:10:02,218
So very pleased with how that all went
in retargeting a second t0,

162
00:10:02,635 --> 00:10:05,304
we picked up, the count

163
00:10:05,304 --> 00:10:08,307
again at t -ten minutes
and we counted down

164
00:10:08,574 --> 00:10:12,812
and we had no holds, no planned holds,
and nothing held us up in term count.

165
00:10:13,129 --> 00:10:16,132
And we went down
and had a cutoff at 29 seconds,

166
00:10:16,549 --> 00:10:20,453
which concluded the,
the terminal part of the count.

167
00:10:20,453 --> 00:10:22,672
And then we got back into our recycle.

168
00:10:22,672 --> 00:10:27,560
And this time, instead of retarget
into t0, we got into our drain.

169
00:10:27,560 --> 00:10:31,614
And I'm happy to report that
through those two different targets of T0,

170
00:10:31,614 --> 00:10:35,034
when we wrapped all that up,
we still had launch window, remaining so

171
00:10:35,401 --> 00:10:40,489
very successful day and very proud of
this team and all that they accomplished.

172
00:10:40,740 --> 00:10:44,360
To get us to yesterday
and then to go execute

173
00:10:44,360 --> 00:10:48,648
with such precision and, with that
I'll hand it over to John.

174
00:10:49,098 --> 00:10:49,982
All right. Thank John.

175
00:10:51,367 --> 00:10:54,503
Obviously yesterday
was really a really good day for us.

176
00:10:54,503 --> 00:10:57,506
I thought the test went extremely well.

177
00:10:58,357 --> 00:11:01,193
The entire team,

178
00:11:01,193 --> 00:11:06,032
really remained focused and vigilant, 
throughout the entire test.

179
00:11:06,032 --> 00:11:08,968
And that that includes the MMT.

180
00:11:08,968 --> 00:11:11,987
You know, when we when we did the test,

181
00:11:11,987 --> 00:11:15,157
three weeks ago,

182
00:11:16,042 --> 00:11:19,045
the hardware was talking to us,
so we listened.

183
00:11:19,612 --> 00:11:22,498
And as Charlie mentioned,

184
00:11:22,498 --> 00:11:26,819
the remediation activities
that we, we took turned out really well.

185
00:11:27,870 --> 00:11:31,374
But again,
no, it was just another opportunity

186
00:11:31,374 --> 00:11:34,377
for us to ring out the system and, and

187
00:11:34,610 --> 00:11:37,263
validate and verify
that we've we've got it.

188
00:11:37,263 --> 00:11:39,582
We've got a good system in place.

189
00:11:39,582 --> 00:11:43,352
Before we put crew on on the launch
vehicle, the rocket,

190
00:11:44,120 --> 00:11:49,225
to go fly on launch day, I thought,

191
00:11:50,793 --> 00:11:52,528
just kind of

192
00:11:52,528 --> 00:11:55,531
I had a little bit of time
to, to reflect on

193
00:11:56,282 --> 00:11:59,635
the launch team
and the MMT throughout the day.

194
00:12:00,653 --> 00:12:03,639
And I really felt like,

195
00:12:04,757 --> 00:12:07,860
we're getting to
we've all gotten to a place where

196
00:12:07,860 --> 00:12:12,448
we've all where we want to be relative
to how sharp we are and how we operate.

197
00:12:13,232 --> 00:12:15,918
You know, it's
you see, you see a lot of times

198
00:12:15,918 --> 00:12:19,371
relative to, our launch frequency.

199
00:12:19,371 --> 00:12:23,342
And so we had to work really hard
through training activities

200
00:12:23,342 --> 00:12:26,328
for all of us to stay on, stay on edge,

201
00:12:27,463 --> 00:12:29,331
teams off looking at the data.

202
00:12:29,331 --> 00:12:31,667
I met with some of them this morning.

203
00:12:31,667 --> 00:12:34,854
So far away, I don't
we don't have any indications

204
00:12:34,854 --> 00:12:38,507
of anything that that we're worried about,
but we're just getting started.

205
00:12:38,507 --> 00:12:40,226
So we'll go through that

206
00:12:41,177 --> 00:12:42,895
and, see what the

207
00:12:42,895 --> 00:12:46,015
teams come up with and address
those as needed.

208
00:12:46,832 --> 00:12:49,101
But overall, it was a good day for us.

209
00:12:49,101 --> 00:12:50,269
Megan, back to you.

210
00:12:50,269 --> 00:12:50,786
Thank you.

211
00:12:50,786 --> 00:12:52,371
Yeah. Thank you so much for those opening
remarks.

212
00:12:52,371 --> 00:12:55,491
It's really great to see how,
we've learned from what trust to

213
00:12:55,558 --> 00:12:58,377
when we had a successful
what dress learn from what dress won.

214
00:12:58,377 --> 00:13:00,713
And we had a successful address to.

215
00:13:00,713 --> 00:13:00,980
All right.

216
00:13:00,980 --> 00:13:03,415
So we are now going to invite reporters
here in person,

217
00:13:03,415 --> 00:13:05,551
as well as over the phone
to ask their questions.

218
00:13:05,551 --> 00:13:09,538
If you're on the phone, remember that
you need to press star Q a star one

219
00:13:09,538 --> 00:13:12,541
to get into the queue and then wait
for a mic to get to you here.

220
00:13:12,541 --> 00:13:13,826
So we'll start
over here. Marsha, go ahead.

221
00:13:16,011 --> 00:13:16,579
Marsha Denton

222
00:13:16,579 --> 00:13:20,182
Associated Press to meet a March 6th
launch attempt.

223
00:13:20,182 --> 00:13:24,987
When would the flight readiness
review need to be held?

224
00:13:24,987 --> 00:13:28,591
When would the crew be getting
what other milestones between now and then

225
00:13:29,008 --> 00:13:32,611
do you have to, be on time for in order

226
00:13:32,611 --> 00:13:35,598
to make that the first time in March?

227
00:13:35,664 --> 00:13:37,683
I'll speak to the,
the programmatic part of that,

228
00:13:37,683 --> 00:13:40,669
and then I'll pass it over to Charlie
to talk some of the the other big

229
00:13:40,669 --> 00:13:44,006
kind of technical things that we have
to get done in this time frame.

230
00:13:44,607 --> 00:13:47,610
You mentioned, 
the flight readiness review.

231
00:13:47,610 --> 00:13:49,345
That's certainly a big one.

232
00:13:49,345 --> 00:13:51,647
It is, targeted
for the end of next week.

233
00:13:51,647 --> 00:13:54,767
That should be in plenty of time,
prior to,

234
00:13:54,767 --> 00:13:58,487
to launch to, to go through
that certification of flight readiness.

235
00:13:58,871 --> 00:14:02,057
It is going to be an extensive
and detailed review.

236
00:14:02,057 --> 00:14:05,611
We are going to go over and comb
every aspect of this system.

237
00:14:05,978 --> 00:14:10,583
And we'll go through that, with our
associate administrator, armature tria.

238
00:14:10,666 --> 00:14:13,669
And I expect, our administrator
will be paying very close

239
00:14:14,036 --> 00:14:18,023
attention as well, as we go through
that certification process.

240
00:14:18,290 --> 00:14:21,627
And then at, launch minus two days,
we hand over responsibility

241
00:14:21,627 --> 00:14:24,630
over to John Hunnicutt as the empty chair.

242
00:14:24,797 --> 00:14:27,800
And as we prepare,
for the launch readiness.

243
00:14:27,917 --> 00:14:29,752
You mentioned the the crew.

244
00:14:29,752 --> 00:14:32,972
The crew will go into what we call
a soft quarantine, or we're calling a soft

245
00:14:32,972 --> 00:14:35,958
quarantine where they're going
into quarantine at Johnson Space Center.

246
00:14:36,025 --> 00:14:37,693
Later today, as I mentioned.

247
00:14:37,693 --> 00:14:41,997
And then, probably at around
l minus five

248
00:14:41,997 --> 00:14:45,084
days or more, that would be the latest,
but it could go a little earlier.

249
00:14:45,084 --> 00:14:47,786
They would, transition here
to Kennedy Space Center

250
00:14:47,786 --> 00:14:50,072
to continue their quarantine
up until launch.

251
00:14:50,072 --> 00:14:52,458
But I'm going to pass it to Charlie,
and she can tell you about the

252
00:14:52,458 --> 00:14:54,977
the big technical milestones
that we need to achieve.

253
00:14:54,977 --> 00:14:58,647
Well, really,
we just have one big milestone left.

254
00:14:58,647 --> 00:15:02,851
We have contingency pad access
that we are installing.

255
00:15:03,168 --> 00:15:06,722
So we got out of, 
got through our drain operations

256
00:15:06,722 --> 00:15:09,291
early this morning and got into a nerding.

257
00:15:09,291 --> 00:15:14,246
We'll get back into the pad,
probably somewhere around, you know,

258
00:15:15,264 --> 00:15:16,165
what time is it now?

259
00:15:16,165 --> 00:15:18,384
Maybe somewhere in the next hour or so.

260
00:15:18,384 --> 00:15:22,021
Certainly by the end of our shift today,
we should have our teams back in.

261
00:15:22,021 --> 00:15:23,572
We're doing the preps for the lift,

262
00:15:23,572 --> 00:15:27,109
so we could be ready for that lift
as soon as this evening.

263
00:15:27,593 --> 00:15:31,580
Once we get the,
the platforms lifted up.

264
00:15:31,747 --> 00:15:33,299
We have two of them.

265
00:15:33,299 --> 00:15:35,868
One of them
that provides access to the entertaining

266
00:15:35,868 --> 00:15:38,971
and to the booster,
and then another that provides, access

267
00:15:38,971 --> 00:15:42,358
just to the boosters will go
in, will establish access.

268
00:15:42,358 --> 00:15:43,592
And those volumes.

269
00:15:43,592 --> 00:15:46,428
And then we go in and do the retest.

270
00:15:46,428 --> 00:15:49,431
And so that involves
disconnecting ordnance,

271
00:15:49,732 --> 00:15:53,752
doing the retest, reconnecting
ordnance back and out of those volumes.

272
00:15:53,752 --> 00:15:57,990
So it's not a short,
you know, 12 hours, amount of work.

273
00:15:57,990 --> 00:15:59,341
It spans several days.

274
00:15:59,341 --> 00:16:03,445
But that's really our big thing
that we have left to do before launch.

275
00:16:03,679 --> 00:16:07,433
Getting through this wet dress was, 
an important milestone for us.

276
00:16:07,433 --> 00:16:09,084
Certainly, there's other work.

277
00:16:09,084 --> 00:16:10,202
You know, we'll continue

278
00:16:10,202 --> 00:16:13,772
with our light snow
and final preparations of the crew module.

279
00:16:13,772 --> 00:16:17,126
We have some lessons learned from
yesterday that will go in and address.

280
00:16:17,393 --> 00:16:20,963
But in terms of the big work
that's left, it it really is

281
00:16:20,963 --> 00:16:23,999
that contingency pad
access and that feeds retest.

282
00:16:25,100 --> 00:16:25,617
Thank you.

283
00:16:25,617 --> 00:16:28,287
Okay, Phil.

284
00:16:28,287 --> 00:16:30,472
Yes I think this is fairly,

285
00:16:30,472 --> 00:16:33,442
you mentioned the mini tanking,
the hydrogen integrity test or whatever.

286
00:16:33,442 --> 00:16:35,811
You know, I think
I'm speaking for a lot of reporters.

287
00:16:35,811 --> 00:16:39,264
We would not have known that was going on
if we didn't ask somebody,

288
00:16:39,648 --> 00:16:40,766
which I don't understand.

289
00:16:40,766 --> 00:16:41,850
I mean, there's a lot of interest

290
00:16:41,850 --> 00:16:45,320
in all of this, and I don't understand
why information is so hard to come by.

291
00:16:45,688 --> 00:16:48,323
I know you talked to us
at these briefings and stuff, but

292
00:16:48,323 --> 00:16:51,210
it's like PA
didn't have permission to tell us things.

293
00:16:51,210 --> 00:16:51,960
That's number one.

294
00:16:51,960 --> 00:16:54,947
If you can just address that,
because you are the launch director.

295
00:16:55,030 --> 00:16:58,467
And secondly, the seals you mentioned,
you have to realize

296
00:16:58,467 --> 00:17:01,020
none of us have ever seen a picture
or a drilling.

297
00:17:01,020 --> 00:17:03,355
We don't know where they are
in the tail service

298
00:17:03,355 --> 00:17:05,357
or how it butts up against the rocket.

299
00:17:05,357 --> 00:17:07,743
And so if you're trying to describe
something like that,

300
00:17:07,743 --> 00:17:09,812
it really helps to have some detail.

301
00:17:09,812 --> 00:17:12,331
You don't have to give away
company secrets and privacy.

302
00:17:12,331 --> 00:17:14,783
It's not it's it's you need a picture.

303
00:17:14,783 --> 00:17:16,902
You need some kind of description
to understand it.

304
00:17:16,902 --> 00:17:18,721
So where are the seals?

305
00:17:18,721 --> 00:17:20,422
Get your picture okay. Okay.

306
00:17:20,422 --> 00:17:21,740
Where are the seals?

307
00:17:21,740 --> 00:17:24,860
What kind of what did you see
when you took the old seals out

308
00:17:25,160 --> 00:17:27,863
that made you confident
new seals were going to fix that?

309
00:17:27,863 --> 00:17:30,149
And how are they arranged
around the eight inch and four inch.

310
00:17:30,149 --> 00:17:30,566
Are they

311
00:17:30,566 --> 00:17:33,902
separate with separate lines in a cavity,
or are they separate cavities?

312
00:17:33,902 --> 00:17:35,087
How does that work? Sorry,

313
00:17:36,088 --> 00:17:36,839
it's all good.

314
00:17:36,839 --> 00:17:38,874
So I'll take a shot at it and then I'll,

315
00:17:38,874 --> 00:17:43,078
if John wants to add anything to it,
I'll hand it over to him.

316
00:17:43,078 --> 00:17:47,066
So, and we
we can absolutely get you some,

317
00:17:47,066 --> 00:17:50,219
some pictures to help out with it,
but you have two different lines

318
00:17:50,219 --> 00:17:51,587
that go into the plate

319
00:17:51,587 --> 00:17:55,290
that forms the interface
between the flight vehicle and the ground.

320
00:17:55,290 --> 00:17:56,692
And those plates come together.

321
00:17:56,692 --> 00:17:58,527
And there are two if you've seen,

322
00:17:58,527 --> 00:18:01,263
if you're looking at that
live shot at the pad, you'll see those,

323
00:18:01,263 --> 00:18:04,316
those two, there's two hoses
that come off of the back of that plate.

324
00:18:04,316 --> 00:18:05,667
Two flex hoses.

325
00:18:05,667 --> 00:18:08,003
One is eight inch.
It's for your fill in drain.

326
00:18:08,003 --> 00:18:10,222
The other is your four
inch, which is your bleed.

327
00:18:11,757 --> 00:18:13,075
Inside of that plate cavity,

328
00:18:13,075 --> 00:18:16,829
there's a seal that goes around
where that interface, meets together.

329
00:18:16,829 --> 00:18:17,780
Pretty simple.

330
00:18:17,780 --> 00:18:22,217
Pretty simple look and seal and, 
and so what we did is that we went in

331
00:18:22,217 --> 00:18:25,370
and we changed both of those out
in terms of findings.

332
00:18:25,437 --> 00:18:28,440
You know, we didn't have any significant

333
00:18:28,891 --> 00:18:31,610
findings
when we went into Into the cavity.

334
00:18:31,610 --> 00:18:35,330
It wasn't like we saw something
where we had a significant

335
00:18:35,330 --> 00:18:38,600
blemish on the seal, and we thought,
this is absolutely,

336
00:18:38,901 --> 00:18:43,138
you know, the root cause are the witness
to the leakage that we saw.

337
00:18:44,123 --> 00:18:46,592
But the team work through the data.

338
00:18:46,592 --> 00:18:50,729
What we did find was there was seem
to be after we removed the seal,

339
00:18:50,729 --> 00:18:54,483
there was a little bit of moisture
in that, in that eight inch area,

340
00:18:56,001 --> 00:18:57,019
where it came from,

341
00:18:57,019 --> 00:19:00,055
I'm not entirely sure,
but we found some moisture there.

342
00:19:00,055 --> 00:19:03,959
And certainly when you get cryogenic, 
temperatures going through there,

343
00:19:03,959 --> 00:19:06,962
you can have some freezing in
that can cause an issue.

344
00:19:07,162 --> 00:19:10,649
We also found that
there was a little bit on the four inch.

345
00:19:10,916 --> 00:19:14,970
There was a little bit of scratches
on there, which we very easily buffed out.

346
00:19:16,138 --> 00:19:20,425
Again, it's not indicative
of the kind of leak that we saw.

347
00:19:21,210 --> 00:19:24,530
During wet dress number one,
the scratches that we experienced.

348
00:19:24,530 --> 00:19:29,301
So when we, when we close up that cavity,
we didn't have one thing

349
00:19:29,301 --> 00:19:32,838
that we could point to where we said
this was absolutely. It.

350
00:19:33,155 --> 00:19:35,908
We had a number of contributing things,

351
00:19:35,908 --> 00:19:38,911
but certainly changing out the Seals,

352
00:19:39,962 --> 00:19:43,982
addressed the problem,
because we had absolutely incredible

353
00:19:43,982 --> 00:19:45,300
performance yesterday.

354
00:19:45,300 --> 00:19:48,954
And just real quick in pressurization for
the last minutes when you press the tank.

355
00:19:49,254 --> 00:19:52,257
And that leak shot up during WDR one,
how did it do this time?

356
00:19:52,457 --> 00:19:54,626
The maximum leak rate.

357
00:19:54,626 --> 00:19:57,512
Let me get that for you, because
I actually, I knew you would ask me.

358
00:19:57,512 --> 00:19:59,598
It was like 1.6%.

359
00:19:59,598 --> 00:20:04,503
1.5% was the highest that we saw,
which, is really pretty impressive

360
00:20:04,519 --> 00:20:06,505
because if you recall, during Artemis
Swan,

361
00:20:06,505 --> 00:20:09,625
even on our launch attempt,
we saw about 6% in that cavity.

362
00:20:10,525 --> 00:20:11,310
Thank you.

363
00:20:11,310 --> 00:20:14,179
I will take one more on the room, will,
and then we'll go to the phones.

364
00:20:16,398 --> 00:20:18,450
Yeah,
we'll Robinson Smith with Spaceflight now.

365
00:20:18,450 --> 00:20:19,985
Thanks for taking the time.

366
00:20:19,985 --> 00:20:24,022
Maybe to juxtapose the leak rate
that you mentioned.

367
00:20:24,022 --> 00:20:26,124
Charlie just a second ago.

368
00:20:26,124 --> 00:20:30,445
You know, the
the limit for WDR one was 16%.

369
00:20:30,445 --> 00:20:34,549
But can you say what the maximum
that you saw actually was,

370
00:20:34,549 --> 00:20:38,453
especially during, tank pressurization
during that, terminal count.

371
00:20:38,754 --> 00:20:41,690
And then to, John Honeycutt

372
00:20:41,690 --> 00:20:47,029
in your, prepared remarks, you mentioned,
you know, relative to the launch

373
00:20:47,029 --> 00:20:51,183
frequency, worked really hard, through
training activities to stay on edge.

374
00:20:51,450 --> 00:20:53,335
I wonder in looking forward to it

375
00:20:53,335 --> 00:20:56,121
and maybe Lori Glaze,
if you want to address this as well.

376
00:20:56,121 --> 00:20:57,873
Looking forward to Artemis three.

377
00:20:57,873 --> 00:21:00,842
How are you working to

378
00:21:00,842 --> 00:21:03,362
mitigate that
and to make sure you stay sharp?

379
00:21:03,362 --> 00:21:04,980
As you know, there's going to be

380
00:21:04,980 --> 00:21:07,983
whatever time there is between now
and the launch of Artemis three.

381
00:21:08,150 --> 00:21:11,536
What sorts of activities
are you doing to keep those skills sharp?

382
00:21:11,536 --> 00:21:12,504
And, you know,

383
00:21:12,504 --> 00:21:16,441
how soon can we expect to hear about the
the crew training for Artemis three?

384
00:21:16,558 --> 00:21:16,908
Thanks.

385
00:21:19,077 --> 00:21:20,779
So I'll I'll answer the part.

386
00:21:20,779 --> 00:21:23,398
Staying sharp and,

387
00:21:23,398 --> 00:21:26,034
kind of put words in Charlie
Charlie's mouth.

388
00:21:26,034 --> 00:21:28,704
She does the same thing that I do with her
launch team.

389
00:21:28,704 --> 00:21:31,707
Right. Just there.

390
00:21:32,007 --> 00:21:35,010
I think her forefathers
that came before her,

391
00:21:35,560 --> 00:21:37,913
they were big on

392
00:21:37,913 --> 00:21:41,033
being vigilant
about testing and staying sharp.

393
00:21:41,750 --> 00:21:44,903
And so I've adapted that same philosophy

394
00:21:45,087 --> 00:21:49,591
for the MMT,
so I, I know we'll continue to do that

395
00:21:49,591 --> 00:21:54,479
as after this mission,
as as we approach our mystery thing.

396
00:21:54,479 --> 00:21:56,832
Thing you want to add, Lord,

397
00:21:56,832 --> 00:21:59,551
I think, you know, even,
you know, John mentioned,

398
00:21:59,551 --> 00:22:02,537
that, even the, the,

399
00:22:02,821 --> 00:22:06,792
the team dynamic and how the team
was working together yesterday.

400
00:22:06,892 --> 00:22:10,612
There were some improvements, over wet
dress one in some of the prior, prior,

401
00:22:11,129 --> 00:22:14,066
trainings that we've done that
they're really, really coming together.

402
00:22:14,066 --> 00:22:18,687
We've actually made some changes
in how the, the MMT works,

403
00:22:18,687 --> 00:22:22,858
the structure of it
and and by phase of the, of the mission

404
00:22:22,858 --> 00:22:25,877
and I think there's a lot of lessons there
that we can take forward to Artemis

405
00:22:25,977 --> 00:22:26,461
three items.

406
00:22:26,461 --> 00:22:29,448
Three is going to be a complex mission,
with multiple,

407
00:22:29,448 --> 00:22:32,868
phases and thinking
about how we can make that MMT.

408
00:22:33,318 --> 00:22:36,671
The most effective
that it can be, to make,

409
00:22:37,189 --> 00:22:39,441
good decisions
in a, in a quick time frame,

410
00:22:39,441 --> 00:22:42,861
but that are well informed
and, take advantage of the insights

411
00:22:42,861 --> 00:22:45,864
from our, our bench depths down below
the tactical depth.

412
00:22:46,381 --> 00:22:47,366
I think there's a lot of lessons

413
00:22:47,366 --> 00:22:49,401
that we've learned that,
that we can take forward.

414
00:22:49,401 --> 00:22:52,704
You did ask about, 
you know, the Artemis three.

415
00:22:52,704 --> 00:22:55,707
When are we going to start thinking
about a crew for Artemis three?

416
00:22:55,707 --> 00:22:59,010
There's still a lot of things that have
to happen, before we're ready to.

417
00:22:59,010 --> 00:23:00,145
To pick this.

418
00:23:00,145 --> 00:23:03,048
The specific crew that we need.

419
00:23:03,048 --> 00:23:06,501
We've got a lot of, general training
that can go that is ongoing.

420
00:23:06,501 --> 00:23:08,687
That can happen before
we're ready to pick that crew.

421
00:23:08,687 --> 00:23:11,690
But we won't pick the crew
until we're where

422
00:23:11,840 --> 00:23:15,360
we have the specific, 
mission operations lined out.

423
00:23:15,360 --> 00:23:19,081
And we can be assured that we're picking
the right crew for the right mission.

424
00:23:20,148 --> 00:23:22,167
Okay,
let's go to the phones for some questions.

425
00:23:22,167 --> 00:23:23,034
We have Irene Klotz.

426
00:23:23,034 --> 00:23:23,335
Go ahead.

427
00:23:23,335 --> 00:23:26,338
I mean.

428
00:23:29,458 --> 00:23:30,258
The administrator

429
00:23:30,258 --> 00:23:34,262
has written something about redesigning
this interface.

430
00:23:34,679 --> 00:23:38,283
Pardon is three at this point,
do you think that that's necessary,

431
00:23:38,283 --> 00:23:41,486
or do you think you now, have,

432
00:23:41,486 --> 00:23:45,857
have this leak issue, 
handled for, for future missions

433
00:23:46,258 --> 00:23:50,278
and could you please discuss we're all
we're all with you for early March, but

434
00:23:50,278 --> 00:23:53,882
if it doesn't work out,
could you please discuss sub plan

435
00:23:54,299 --> 00:23:59,938
or launch options beyond, from what
you've told us before, the early April

436
00:23:59,938 --> 00:24:04,893
in that window would not be available, 
due to the, battery checkouts.

437
00:24:04,893 --> 00:24:08,880
And I've tried for a month
to get the rest of the window.

438
00:24:09,281 --> 00:24:13,068
That opens April 30th, to no avail.

439
00:24:13,068 --> 00:24:17,556
And echoing those comments about please
bring your very good

440
00:24:18,089 --> 00:24:20,575
staff to tell us what they know.

441
00:24:20,575 --> 00:24:23,578
Thank. Yeah. Go ahead, John, you go first.

442
00:24:23,578 --> 00:24:27,299
I'll, I'll take the the the seal part.

443
00:24:29,301 --> 00:24:29,818
So I think

444
00:24:29,818 --> 00:24:32,854
last time we got together,
I told you about how tricky hydrogen was.

445
00:24:32,854 --> 00:24:36,057
That small, small molecule,
very energetic.

446
00:24:36,057 --> 00:24:40,562
And, it likes to find leak pass.

447
00:24:41,313 --> 00:24:44,299
We've seen that throughout history.

448
00:24:45,901 --> 00:24:48,687
This this team has worked

449
00:24:48,687 --> 00:24:53,191
very hard since Artemis one and knew

450
00:24:53,191 --> 00:24:57,979
we had work to do to get us into a place
where we weren't having these problems.

451
00:24:59,064 --> 00:25:03,568
And I can promise you that they addressed
everything that we could get addressed.

452
00:25:04,402 --> 00:25:07,405
Yet we still ran into this.

453
00:25:07,873 --> 00:25:10,876
I would share with you that,

454
00:25:11,776 --> 00:25:15,213
the team still got some open legs
on their fault today

455
00:25:15,230 --> 00:25:18,500
that they've been working, but I think
they got some good data in this round.

456
00:25:19,851 --> 00:25:24,472
We'll have to see where that drives them
in order to to answer the question.

457
00:25:26,274 --> 00:25:27,325
And, you know, if you

458
00:25:27,325 --> 00:25:30,629
recall, on Artemis one,
we did the same thing.

459
00:25:31,379 --> 00:25:34,382
We changed the seals at the pad.

460
00:25:35,250 --> 00:25:37,919
And we were successful.

461
00:25:37,919 --> 00:25:39,588
So here we are.

462
00:25:39,588 --> 00:25:43,291
Over the last three weeks,
we changed the seals with the pad

463
00:25:44,359 --> 00:25:45,377
and we were successful.

464
00:25:45,377 --> 00:25:48,146
So again, the hardware is talking to us.

465
00:25:48,146 --> 00:25:49,614
I don't want to get ahead of the team.

466
00:25:49,614 --> 00:25:52,467
I think they've got some theories
about what's going on there.

467
00:25:52,467 --> 00:25:54,903
But we'll lift and drive closer.

468
00:25:54,903 --> 00:25:58,940
But, I do, know the administrator
wants to make this leak proof,

469
00:25:58,940 --> 00:26:01,042
and I think we're on a good path.

470
00:26:01,042 --> 00:26:04,045
Get a good opportunity to do that.

471
00:26:05,297 --> 00:26:05,997
Okay.

472
00:26:05,997 --> 00:26:07,349
Ken Chang, New York Times.

473
00:26:07,349 --> 00:26:10,051
Go ahead, Ken.

474
00:26:10,051 --> 00:26:11,069
All right. Simple question.

475
00:26:11,069 --> 00:26:14,556
When would you set a launch date
with that?

476
00:26:14,573 --> 00:26:15,991
You have to the flight readiness review.

477
00:26:17,425 --> 00:26:20,879
As I said,
I think we are going to target the sixth.

478
00:26:20,879 --> 00:26:24,266
It's pending the successful,
work at the pad.

479
00:26:24,449 --> 00:26:27,569
And the successful,
certification of flight

480
00:26:27,569 --> 00:26:30,572
readiness, which I said it,
we anticipate the end of next week.

481
00:26:30,805 --> 00:26:33,241
So I think we can keep an eye
on those activities.

482
00:26:33,241 --> 00:26:36,227
If something happens
that pushes us off away from the six

483
00:26:36,227 --> 00:26:40,498
based on the experience that we're having
or over the next week or so,

484
00:26:40,498 --> 00:26:44,069
we will certainly communicate, communicate
that and be transparent about it.

485
00:26:45,470 --> 00:26:48,139
So, let's, let's all keep our eyes out.

486
00:26:48,139 --> 00:26:52,127
We'll, we'll be, I'm sure, posting
regular blogs, updates on how we're doing

487
00:26:52,127 --> 00:26:55,196
with the contingency pad access
and the work that's going to go on,

488
00:26:55,196 --> 00:26:56,548
with the flight termination systems

489
00:26:56,548 --> 00:26:59,551
in the booster
and the inner tank area of the core stage.

490
00:26:59,701 --> 00:27:02,454
And, you know,
if there's something there that looks like

491
00:27:02,454 --> 00:27:04,589
it could threaten the sixth,
we will certainly,

492
00:27:04,589 --> 00:27:07,108
let everyone know that we could
we could move off of that.

493
00:27:07,108 --> 00:27:10,078
But for right now, that's
that's the direction that we're headed.

494
00:27:10,078 --> 00:27:15,300
I think there was also the question
earlier about other launch, availability,

495
00:27:15,300 --> 00:27:19,587
the later launch periods,
in particular, I guess that would be,

496
00:27:20,555 --> 00:27:24,442
20 launch period 20 that opens on April
30th and beyond.

497
00:27:24,492 --> 00:27:30,081
We'll certainly take that, comment, 
seriously and take a look at, if we're,

498
00:27:30,081 --> 00:27:33,168
if we've there's still a lot of analysis
that has to go into those.

499
00:27:33,168 --> 00:27:35,120
And so the three launch periods
that we released

500
00:27:35,120 --> 00:27:36,438
are the ones that have been analyzed

501
00:27:36,438 --> 00:27:39,140
most closely,
where we understand the constraints.

502
00:27:39,140 --> 00:27:42,527
You know, we've talked before
about all the various parameters

503
00:27:42,527 --> 00:27:47,098
that can impact the launch availability,
including of, you know, thermal,

504
00:27:47,132 --> 00:27:52,337
thermal state of Orion,
eclipses, communications

505
00:27:52,337 --> 00:27:55,824
constraints, the the heat shield
that we've talked about previously.

506
00:27:56,508 --> 00:27:59,327
And so there's a lot of analyzes
that need to go into determining

507
00:27:59,327 --> 00:28:03,798
exactly which of those dates,
have appropriate, launch,

508
00:28:03,798 --> 00:28:07,669
windows or launch, yeah, launch windows
within those, periods.

509
00:28:08,053 --> 00:28:10,922
So if those are when those are ready,

510
00:28:10,922 --> 00:28:13,975
we'll make sure we get the,
the additional, periods out.

511
00:28:13,975 --> 00:28:16,828
But, you know, if we're lucky,
maybe we won't. We won't need those.

512
00:28:18,380 --> 00:28:20,432
Okay, we'll take one more on the, phone.

513
00:28:20,432 --> 00:28:23,418
Micah maiden, BRB, Wall Street Journal,
and then we'll go to the room again.

514
00:28:23,418 --> 00:28:26,037
Michael, go ahead.

515
00:28:26,037 --> 00:28:26,821
Hey. Good morning.

516
00:28:26,821 --> 00:28:30,258
Has the team conducted
any analysis of the impact,

517
00:28:31,025 --> 00:28:36,047
if any, the weather may have had
on the vehicles or ground systems?

518
00:28:36,197 --> 00:28:39,200
Just given some of the cold temperatures
seen earlier.

519
00:28:39,751 --> 00:28:41,002
Are you tracking anything there?

520
00:28:41,002 --> 00:28:44,005
Thanks.

521
00:28:44,789 --> 00:28:45,707
I can take you to.

522
00:28:45,707 --> 00:28:48,860
I, so we do not believe that

523
00:28:48,860 --> 00:28:53,181
the cold temperatures had an effect
on the performance of the cavity.

524
00:28:53,181 --> 00:28:57,001
Just because the ambient conditions are,
I'll say,

525
00:28:57,001 --> 00:29:00,739
so much kinder than the temperatures
that are flowing through that interface.

526
00:29:00,805 --> 00:29:05,460
But certainly we did see
during the performance of the wet dress,

527
00:29:05,460 --> 00:29:08,546
we did see in
some of our systems out at the pad

528
00:29:09,497 --> 00:29:12,450
that, we had some thermal effects
from that.

529
00:29:12,450 --> 00:29:16,671
And, and so we have gone through
and taken action on those.

530
00:29:16,671 --> 00:29:20,091
And by that, what I mean is that,
you know, you have certain certain

531
00:29:20,091 --> 00:29:24,145
pneumatic systems that you set up
based on ambient conditions,

532
00:29:24,145 --> 00:29:28,500
as we saw the fluctuation in temperature
or some of those needed some adjustments.

533
00:29:28,500 --> 00:29:30,201
So, we did see that.

534
00:29:30,201 --> 00:29:33,271
But in terms of performance
of that interface, we do not believe it

535
00:29:33,271 --> 00:29:36,558
was, an ambient condition
related, issue.

536
00:29:38,643 --> 00:29:41,629
Okay, let's come back in the room
here. Can.

537
00:29:45,467 --> 00:29:46,351
Thank you, Ken Kramer.

538
00:29:46,351 --> 00:29:47,485
Space up close. First.

539
00:29:47,485 --> 00:29:49,921
Congratulations. The spectacular.

540
00:29:49,921 --> 00:29:52,323
I was here last night
and thoroughly enjoyed it.

541
00:29:52,323 --> 00:29:54,776
And and can't wait to go back to the moon.

542
00:29:54,776 --> 00:29:56,678
So I get a couple of questions.

543
00:29:56,678 --> 00:29:59,681
Talking about, first John,

544
00:29:59,781 --> 00:30:02,116
the seals and the filters.

545
00:30:02,116 --> 00:30:04,519
So you replace them two times.

546
00:30:04,519 --> 00:30:09,507
What I'm wondering is, do you need or
would you consider replacing them again,

547
00:30:10,074 --> 00:30:14,813
or are you going to use the seals
and the filters that are in place now?

548
00:30:15,296 --> 00:30:17,098
And I also want to ask,

549
00:30:19,517 --> 00:30:21,052
To back up Bill's comments.

550
00:30:21,052 --> 00:30:24,055
I've asked for a reentry trajectory.

551
00:30:24,088 --> 00:30:25,557
Okay. There's one for Artemis.

552
00:30:25,557 --> 00:30:28,560
One I've asked a couple times
for Artemis two,

553
00:30:28,860 --> 00:30:31,279
if you could
if you could make that available.

554
00:30:31,279 --> 00:30:34,282
Okay. And with a little explanation.

555
00:30:34,382 --> 00:30:38,219
You know, we've heard general terms,
but I'd like to hear some details why

556
00:30:38,219 --> 00:30:42,590
it is better, compared to Artemis one,
you're not doing the skip reentry.

557
00:30:43,141 --> 00:30:45,059
You know, give us some details about.

558
00:30:45,059 --> 00:30:46,761
That would be extremely helpful.

559
00:30:46,761 --> 00:30:49,647
Thank you.

560
00:30:49,647 --> 00:30:50,148
Let's see.

561
00:30:50,148 --> 00:30:54,018
So the seals in the filter
are two separate issues.

562
00:30:55,103 --> 00:30:58,089
We ran into the filter problem on the

563
00:30:58,172 --> 00:31:01,159
during the confidence test.

564
00:31:01,759 --> 00:31:04,078
The eggs folks in the filters

565
00:31:04,078 --> 00:31:07,081
on the, on the skid, on the email.

566
00:31:07,098 --> 00:31:11,152
And so Charlie's
team, went through that part.

567
00:31:11,152 --> 00:31:13,104
So I'll let her describe that.

568
00:31:16,007 --> 00:31:16,674
I think right

569
00:31:16,674 --> 00:31:19,827
now, as always, if we ran into a challenge

570
00:31:20,428 --> 00:31:23,431
on the Seals, we would look at the data

571
00:31:24,415 --> 00:31:27,835
and make a decision
about what the next steps would be.

572
00:31:29,037 --> 00:31:32,390
I will tell you right now, I got
I got a pretty high

573
00:31:32,390 --> 00:31:35,393
level of confidence in the configuration
that we're in right now.

574
00:31:36,060 --> 00:31:37,262
It's out there at the pad.

575
00:31:37,262 --> 00:31:40,248
It's going to be there at the pad
until we go fly.

576
00:31:40,498 --> 00:31:44,786
Very little influences
can go on to change

577
00:31:44,786 --> 00:31:46,988
the configuration we're in right now.

578
00:31:46,988 --> 00:31:48,656
You know, talk about filter.

579
00:31:48,656 --> 00:31:50,842
Sure. And I would agree with John.

580
00:31:50,842 --> 00:31:54,445
There would be no, no plan to go
change the Seals.

581
00:31:54,445 --> 00:31:57,715
We had great performance yesterday and,

582
00:31:57,715 --> 00:32:01,502
and there would be no reason to go relook
at those in terms of the filter.

583
00:32:01,736 --> 00:32:02,420
John said it.

584
00:32:02,420 --> 00:32:06,658
It's on the Kraus skid
that's on the mobile launcher and,

585
00:32:06,658 --> 00:32:10,228
and so what happened
during the confidence test is that

586
00:32:10,411 --> 00:32:14,449
we saw a Delta P, across that filter
that we didn't expect.

587
00:32:14,449 --> 00:32:18,303
And it was right around the time
that we were transitioning to fast fill.

588
00:32:19,887 --> 00:32:21,422
So what we were left

589
00:32:21,422 --> 00:32:24,509
with was did we have something
that was clogged in the filter?

590
00:32:24,542 --> 00:32:27,295
Was the filter frozen? What caused that?

591
00:32:27,295 --> 00:32:31,466
And so we went in and we had to wait
a couple of days for it to warm up,

592
00:32:31,466 --> 00:32:33,267
get it up to the right temperatures,
because the last thing

593
00:32:33,267 --> 00:32:36,237
you want to do in a crowd
system is introduce moisture.

594
00:32:36,237 --> 00:32:38,539
And, 
and so we went in, pulled that filter out.

595
00:32:38,539 --> 00:32:41,492
What we found was that it wasn't clogged.

596
00:32:41,492 --> 00:32:43,911
So we were left with
there's no debris in it.

597
00:32:43,911 --> 00:32:49,434
And and so it was likely some air that
got ingested into the system somewhere.

598
00:32:49,434 --> 00:32:51,769
And it froze, 
as part of those operations.

599
00:32:51,769 --> 00:32:54,772
So we parked it out,
put it in a brand new filter,

600
00:32:54,839 --> 00:32:59,627
and continued our purges and again,
had really good performance yesterday.

601
00:32:59,627 --> 00:33:02,397
We would have no plan to
go in and touch that again.

602
00:33:04,682 --> 00:33:06,534
You know,
one of the things that kind of systems

603
00:33:06,534 --> 00:33:10,188
is one of the ways you can actually have
problems is when you open them up,

604
00:33:11,239 --> 00:33:13,591
it's safer to keep them buttoned up. Yeah.

605
00:33:13,591 --> 00:33:14,809
You know, they're working.

606
00:33:14,809 --> 00:33:17,812
This technical community works
closely together.

607
00:33:18,246 --> 00:33:23,818
I got to give kudos to,
the ULA folks and and some other folks

608
00:33:23,818 --> 00:33:28,339
that stepped in and worked with the guys
and Celeste guys to share,

609
00:33:29,040 --> 00:33:32,043
some of their learnings relative to,

610
00:33:34,262 --> 00:33:35,747
Frozen or nitrogen?

611
00:33:35,747 --> 00:33:38,933
Frozen nitrogen
or frozen air in their filters.

612
00:33:39,317 --> 00:33:40,134
And they had seen it.

613
00:33:40,134 --> 00:33:43,638
They had seen it before, too,
in that they provided some valuable data

614
00:33:43,638 --> 00:33:46,641
to help drive this thing to closure.

615
00:33:47,341 --> 00:33:49,977
I'll address the question
about the Artemis two trajectory.

616
00:33:49,977 --> 00:33:51,379
Thank you for the comment.

617
00:33:51,379 --> 00:33:52,547
We'll see what we can do.

618
00:33:52,547 --> 00:33:54,716
Getting you some information there.

619
00:33:54,716 --> 00:33:56,317
Some more detailed information.

620
00:33:56,317 --> 00:34:00,204
The I wouldn't say,
that the Artemis two trajectory

621
00:34:00,204 --> 00:34:03,558
is, is, you know, in any way
a better trajectory than Artemis one?

622
00:34:03,558 --> 00:34:07,261
It's different, and it's uniquely designed
specifically for,

623
00:34:07,612 --> 00:34:11,149
the Orion heat shield capabilities
that we have for Artemis two.

624
00:34:11,516 --> 00:34:12,834
It's also uniquely,

625
00:34:14,118 --> 00:34:15,019
designed

626
00:34:15,019 --> 00:34:17,839
based on this free return trajectory
that we have.

627
00:34:17,839 --> 00:34:22,527
So it's not an entry, profile
that we would use on, for the Artemis

628
00:34:22,577 --> 00:34:23,811
three mission, for example.

629
00:34:23,811 --> 00:34:26,697
That's in orbit around the moon
and then coming back to Earth.

630
00:34:26,697 --> 00:34:30,384
It is something that we have the ability
because we're on this free return,

631
00:34:30,384 --> 00:34:32,537
we can use a specific trajectory

632
00:34:32,537 --> 00:34:35,790
that allows us to come in and manage
those, heat loads.

633
00:34:36,407 --> 00:34:41,279
On the Artemis two heat shield, which we,
we believe we now, on all of the work

634
00:34:41,279 --> 00:34:45,149
that's been done since Artemis one,
understand what we expect

635
00:34:45,149 --> 00:34:46,768
the performance of that heat shield to be.

636
00:34:46,768 --> 00:34:49,704
Specifically, we will make changes
to the heat shield for our industry.

637
00:34:49,704 --> 00:34:50,838
In fact, it's already built.

638
00:34:50,838 --> 00:34:53,541
It's, sitting over in
the OMC building right now.

639
00:34:54,709 --> 00:34:57,628
So, this is a unique

640
00:34:57,628 --> 00:35:02,366
trajectory, and,
it's it's specific for this mission.

641
00:35:02,750 --> 00:35:06,120
But I do take your point and we'll see if
we can get you some more detail on that.

642
00:35:07,071 --> 00:35:07,371
Thank you.

643
00:35:07,371 --> 00:35:11,425
Thank you know that that's a different
just unique for sure.

644
00:35:11,709 --> 00:35:13,711
It's unique just to Artemis two.

645
00:35:13,711 --> 00:35:15,863
We won't use this type of trajectory again

646
00:35:15,863 --> 00:35:18,866
when we have the more capable heat shield.

647
00:35:19,734 --> 00:35:20,401
Oh, sorry.

648
00:35:20,401 --> 00:35:23,421
Ken, do you mind if we have a couple
of other people online as well?

649
00:35:23,421 --> 00:35:23,821
Do you mind?

650
00:35:23,821 --> 00:35:25,673
We'll try to get back around to you,
we promise.

651
00:35:25,673 --> 00:35:25,940
All right.

652
00:35:25,940 --> 00:35:28,943
Megan, over there.

653
00:35:30,178 --> 00:35:31,345
First of all, congratulations.

654
00:35:31,345 --> 00:35:33,181
Megan Moriarty with Wesh two here.

655
00:35:33,181 --> 00:35:35,783
First and foremost, what?

656
00:35:35,783 --> 00:35:37,068
I guess specifically for Charlie.

657
00:35:37,068 --> 00:35:40,638
What kind of emotions
were you feeling at 10:16 p.m.

658
00:35:40,638 --> 00:35:41,272
last night?

659
00:35:41,272 --> 00:35:44,692
And how confident are you for
a march launch date?

660
00:35:44,959 --> 00:35:48,596
And then for just for logistics purposes,
besides March 6th,

661
00:35:48,596 --> 00:35:52,400
what are some of the other, dates
that we could possibly see this launch?

662
00:35:54,018 --> 00:35:55,670
All right, so how did I feel last night?

663
00:35:55,670 --> 00:35:59,190
I felt great, 
the team had worked really hard.

664
00:35:59,190 --> 00:36:03,077
We had had some challenges in Artemis
one, and, you know,

665
00:36:03,511 --> 00:36:06,647
our, SLS chief engineer and my friend
John Blevins

666
00:36:06,647 --> 00:36:09,650
often says you have to
you have to earn your right to fly.

667
00:36:09,984 --> 00:36:14,038
And I felt like last night was a big step
in us earning our right to fly.

668
00:36:14,639 --> 00:36:16,524
So, felt really good.

669
00:36:16,524 --> 00:36:20,094
Very proud of the team
because, you know, they,

670
00:36:20,244 --> 00:36:25,049
continue to work through the challenges,
whether it was in the integrity test,

671
00:36:25,049 --> 00:36:29,453
whether it was in, the wet dress
and all of this really does prepare you

672
00:36:29,453 --> 00:36:29,904
to fly.

673
00:36:29,904 --> 00:36:34,825
You know, John talked about
how the team executed and all of that.

674
00:36:34,942 --> 00:36:40,431
You know, I would say that proficiency
and execution and, timelines, the way

675
00:36:40,431 --> 00:36:45,536
that they've matured, the procedures,
all of that, was reflected last night.

676
00:36:45,536 --> 00:36:47,939
And it's all a testament to the work
that the

677
00:36:47,939 --> 00:36:49,607
that the team did to be ready for that.

678
00:36:49,607 --> 00:36:51,292
So I felt really good about it.

679
00:36:51,292 --> 00:36:53,244
Good about the task, proud of the team.

680
00:36:54,629 --> 00:36:56,697
How do I feel about March 6th?

681
00:36:56,697 --> 00:36:58,165
I mean, is Laurie talked about it.

682
00:36:58,165 --> 00:37:00,234
You know, we have to get through
the flight readiness review.

683
00:37:00,234 --> 00:37:05,940
We got work ahead of us, but certainly, as
I told our team during the, the pretest

684
00:37:05,940 --> 00:37:09,911
briefing for wet dress, you know,
we have two big jobs ahead of us.

685
00:37:09,927 --> 00:37:14,849
One was a successful wet dress and meeting
our, test objectives for that.

686
00:37:15,600 --> 00:37:18,753
And, you know, during Artemis one,
we left a few of those on the table,

687
00:37:18,753 --> 00:37:21,956
and we still made
a successful run at launch,

688
00:37:21,956 --> 00:37:24,959
even though there was a few of those
we didn't demonstrate

689
00:37:25,343 --> 00:37:25,826
last night.

690
00:37:25,826 --> 00:37:27,628
We demonstrated them all.

691
00:37:27,628 --> 00:37:33,567
So, that gives me great confidence
in going into launch countdown relative

692
00:37:33,567 --> 00:37:36,570
to how to load the vehicle,
the performance of the seals,

693
00:37:36,570 --> 00:37:40,041
the performance of the team kind of things
you might see in term count.

694
00:37:41,609 --> 00:37:42,677
Let's see.

695
00:37:42,677 --> 00:37:46,230
And then the other work
that's ahead of us is the contingency

696
00:37:46,230 --> 00:37:47,782
pad access that I talked about.

697
00:37:47,782 --> 00:37:50,268
That is the first time up at the pad.

698
00:37:50,268 --> 00:37:51,502
So we haven't done that before.

699
00:37:51,502 --> 00:37:55,706
It's a new capability
we developed for Artemis two specific

700
00:37:55,706 --> 00:38:01,946
to providing a retest of the flight
termination system at the pad.

701
00:38:01,946 --> 00:38:05,700
If you recall, for on this one,
we roll back, to retest that.

702
00:38:05,700 --> 00:38:07,652
That's where we have access in the VAB.

703
00:38:07,652 --> 00:38:11,939
So we have these,
these two access trusses that we install

704
00:38:11,939 --> 00:38:16,310
on the mobile launcher provides temporary
access out to those, compartments

705
00:38:16,610 --> 00:38:19,613
so that we can access the ordnance
and we can go retest it.

706
00:38:20,181 --> 00:38:23,334
So, I will have you a much better

707
00:38:23,334 --> 00:38:26,721
answer on how that goes,
once we get into the work.

708
00:38:27,054 --> 00:38:30,257
But, 
that is really the last remaining thing

709
00:38:30,257 --> 00:38:31,709
other than just, you know, button

710
00:38:31,709 --> 00:38:35,179
and everything, getting into
your final configuration for launch.

711
00:38:35,813 --> 00:38:37,648
So I feel I feel pretty good about that.

712
00:38:42,303 --> 00:38:44,188
Yeah, we have, I believe our

713
00:38:44,188 --> 00:38:47,808
launch window goes through the 11th, so.

714
00:38:49,493 --> 00:38:52,113
Yeah, six, seven, eight, nine and 11.

715
00:38:52,113 --> 00:38:54,031
And that's online. Exactly.

716
00:38:54,031 --> 00:38:55,232
Can I just add one more?

717
00:38:55,232 --> 00:38:58,219
Just quick note to follow,
Charlie, we've talked a lot

718
00:38:58,219 --> 00:39:01,222
about what we've learned
through the wet dress rehearsal and where,

719
00:39:01,639 --> 00:39:04,825
our levels of confidence
in getting to the launch.

720
00:39:04,825 --> 00:39:08,763
But I did just also want to stress this
continues to be this is a flight test.

721
00:39:08,829 --> 00:39:11,482
The whole mission is still a flight test.

722
00:39:11,482 --> 00:39:14,785
This is our second time to fly
the SLS and Orion systems.

723
00:39:15,052 --> 00:39:17,872
The first time with crew, the first time
with,

724
00:39:17,872 --> 00:39:20,908
the environmental control systems
active, the first time

725
00:39:20,908 --> 00:39:24,362
with the flight termination systems active
so that we can support crew.

726
00:39:24,678 --> 00:39:27,331
So I just want to keep people,
you know, in your mind,

727
00:39:27,331 --> 00:39:28,249
you know, we're talking about

728
00:39:28,249 --> 00:39:31,469
how confident we are in getting to launch
and our excitement about this mission.

729
00:39:31,469 --> 00:39:34,221
But I don't want anybody
to ever lose sight of the fact that this

730
00:39:34,221 --> 00:39:37,758
is a flight test and the entire mission,
we will continue to learn.

731
00:39:37,975 --> 00:39:40,811
That's the whole point of this
mission, is to learn.

732
00:39:40,811 --> 00:39:40,978
Okay.

733
00:39:40,978 --> 00:39:43,381
We'll take one more in the room here
before going on the phones.

734
00:39:43,381 --> 00:39:43,948
Thank you.

735
00:39:45,349 --> 00:39:47,268
I teach you mascara with the Epoch Times.

736
00:39:47,268 --> 00:39:49,937
Thank you so much. And again,
congratulations.

737
00:39:49,937 --> 00:39:53,057
Can you elaborate a little more
on, what?

738
00:39:53,307 --> 00:39:55,643
Work the closeout crew still has to do.

739
00:39:55,643 --> 00:39:58,796
And, and talk about all the,

740
00:39:58,796 --> 00:40:02,216
the changes that were made, from, what,
just 1 to 1?

741
00:40:02,233 --> 00:40:04,602
Just to thank you.

742
00:40:04,602 --> 00:40:09,240
So for the closeout crew,
we did deploy them to the pad yesterday.

743
00:40:09,240 --> 00:40:12,243
We wanted to demonstrate the close
out of the Orion crew module,

744
00:40:12,676 --> 00:40:15,563
and all of our procedures we didn't have.

745
00:40:15,563 --> 00:40:18,933
I wouldn't say we had any significant
changes in the plans.

746
00:40:18,933 --> 00:40:20,718
Other than you may recall.

747
00:40:20,718 --> 00:40:24,288
There were some, I'll say
some minor things that we wanted to

748
00:40:24,505 --> 00:40:28,826
to go take a look at, in terms of
and some of them are very small.

749
00:40:28,826 --> 00:40:29,126
Right.

750
00:40:29,126 --> 00:40:32,396
We had, and one simple one.

751
00:40:32,396 --> 00:40:32,630
Right.

752
00:40:32,630 --> 00:40:34,949
The elevators on the two 74ft level.

753
00:40:34,949 --> 00:40:36,834
We have blast doors up there.

754
00:40:36,834 --> 00:40:38,302
Those doors were closed out,

755
00:40:39,270 --> 00:40:42,356
for when the closeout crew arrived
at the pad.

756
00:40:42,356 --> 00:40:43,591
Normally, those are left open

757
00:40:43,591 --> 00:40:47,094
so that when the elevator doors open,
you can walk right out onto 74.

758
00:40:47,094 --> 00:40:48,829
Said that during wet dress, one

759
00:40:48,829 --> 00:40:52,016
kind of held us up for a few minutes
while they configured the doors.

760
00:40:53,100 --> 00:40:56,303
That's a simple thing, but those are the
that set of simple things

761
00:40:56,303 --> 00:41:00,207
that on launch day can cost you
sometimes minutes, that matter.

762
00:41:00,441 --> 00:41:03,928
And so we wanted to go back through
and do our closeout one more time.

763
00:41:04,195 --> 00:41:07,681
The, 
the closeout crew performed, amazing.

764
00:41:07,882 --> 00:41:09,033
They deployed to the pad.

765
00:41:09,033 --> 00:41:10,401
They were right on their timelines.

766
00:41:10,401 --> 00:41:12,953
We didn't have any significant issues.

767
00:41:12,953 --> 00:41:16,707
As part of the closeout activities,
we do plan to do one more demo,

768
00:41:17,024 --> 00:41:20,010
before flight
just because, you know, John talked about

769
00:41:21,061 --> 00:41:22,980
the, you know, our launch rate

770
00:41:22,980 --> 00:41:27,268
and talked about the opportunities
to to go through and do training.

771
00:41:27,268 --> 00:41:31,622
And in the case of the closeout crew,
there isn't a full trainer

772
00:41:31,622 --> 00:41:36,810
anywhere that gives you the crew module
hatch and, and the last hatch

773
00:41:37,077 --> 00:41:38,245
and the white room.

774
00:41:38,245 --> 00:41:42,416
And so we where we get that
is, is in the white room

775
00:41:42,416 --> 00:41:43,434
with the flight hardware.

776
00:41:43,434 --> 00:41:46,437
So we do intend to do one more closeout
demo,

777
00:41:46,620 --> 00:41:49,857
just, to refine our timelines
and look at it one more time.

778
00:41:49,857 --> 00:41:52,860
But I don't envision
any significant changes as a result.

779
00:41:52,877 --> 00:41:55,129
Team did great yesterday, right.

780
00:41:55,129 --> 00:41:55,946
Thank you for that question.

781
00:41:55,946 --> 00:41:57,331
We'll go on the phones now.

782
00:41:57,331 --> 00:42:00,317
Marcia Smith, space policy online.

783
00:42:01,318 --> 00:42:03,470
Thanks so much for taking my question.

784
00:42:03,470 --> 00:42:04,071
Questions.

785
00:42:04,071 --> 00:42:06,891
Actually,
I think I have two of them for Laurie.

786
00:42:06,891 --> 00:42:10,711
The first one is about, comment
you made a little bit earlier

787
00:42:10,711 --> 00:42:13,731
about for Artemis three,
and you wouldn't be picking the crew.

788
00:42:14,148 --> 00:42:17,101
There's you had to pick the right crew
for the right mission.

789
00:42:17,101 --> 00:42:20,387
And could you elaborate on that
a little bit?

790
00:42:20,387 --> 00:42:24,558
And does that reflect questions
about which human landing system

791
00:42:24,558 --> 00:42:27,561
you're going to be using,
and is there any update on that

792
00:42:27,745 --> 00:42:32,600
and near-term for Artemis two,
I'm wondering what NASA's strategy is

793
00:42:32,600 --> 00:42:35,970
for getting the word out to the public
about are the two,

794
00:42:36,003 --> 00:42:39,273
because I'm still surprised
at how many people don't even know

795
00:42:39,273 --> 00:42:40,374
that we're going back to the moon.

796
00:42:42,593 --> 00:42:45,362
I'll take your, your first question
first.

797
00:42:45,362 --> 00:42:46,931
Yes.

798
00:42:46,931 --> 00:42:51,001
So, as you know, we are, 
we have been over the last several months,

799
00:42:51,051 --> 00:42:54,438
thinking about trying to introduce
a little bit more of a competitive nature

800
00:42:54,438 --> 00:42:58,142
and in trying to 
get our crew to the lunar surface.

801
00:42:58,142 --> 00:43:03,981
And so we are, looking at potential,
you know, the potential of having either

802
00:43:03,981 --> 00:43:09,870
the, the starship or the, the Blue Origin,
lander, capability, landing capability.

803
00:43:09,870 --> 00:43:11,538
So that will make a difference
in training.

804
00:43:11,538 --> 00:43:15,392
We, and then also just even as we refine,

805
00:43:15,442 --> 00:43:18,929
the work that we want to do
on the lunar surface,

806
00:43:19,246 --> 00:43:23,300
that will also define exactly,
what types of capabilities that we need,

807
00:43:23,300 --> 00:43:27,054
the complement of capabilities
that we're going to need, with that crew.

808
00:43:27,254 --> 00:43:29,807
So that's,
that's kind of where, where we are,

809
00:43:29,807 --> 00:43:32,960
what's going to drive, 
drive the selection.

810
00:43:32,960 --> 00:43:37,615
So I would anticipate, you know,
over the next many months or year

811
00:43:37,615 --> 00:43:41,518
or so, starting to really refine and
think through, what that will look like.

812
00:43:41,518 --> 00:43:43,520
So stay tuned. On that.

813
00:43:45,356 --> 00:43:48,592
Let's
see the the first question had to do.

814
00:43:48,592 --> 00:43:50,110
I'm sorry, what was the first one on.

815
00:43:50,110 --> 00:43:52,713
The second question on the Artemis two.

816
00:43:52,713 --> 00:43:56,417
How would you get people to oh,
get the people to know about it more. Yes.

817
00:43:56,717 --> 00:44:01,772
Well, am I, yes, I agree, we need
we need to start getting the word out.

818
00:44:01,772 --> 00:44:04,591
Let's let's do that. I'm going to rely on
you guys to help us a lot.

819
00:44:04,591 --> 00:44:09,146
In in getting the news out
and getting the story out, and, NPO folks

820
00:44:09,480 --> 00:44:14,818
as well, and hopefully, by, leaning
in a little harder on when we think

821
00:44:14,818 --> 00:44:18,956
we really anticipate, our ability
to launch, hopefully in March.

822
00:44:19,757 --> 00:44:21,992
I think that that helps a lot as well,

823
00:44:21,992 --> 00:44:24,561
where it's
not an ambiguous time in the future.

824
00:44:24,561 --> 00:44:28,999
We've had the successful,
wet dress rehearsal yesterday.

825
00:44:28,999 --> 00:44:31,518
I think a lot of folks, up to this point
have said, you know,

826
00:44:31,518 --> 00:44:34,521
we watched Artemis one
and it went, you know,

827
00:44:34,521 --> 00:44:37,374
significantly beyond
when we first started talking about it.

828
00:44:37,374 --> 00:44:38,726
But this is really getting real,

829
00:44:38,726 --> 00:44:41,729
and it's time to get serious
and start getting excited.

830
00:44:41,845 --> 00:44:43,580
All right,
next question on the phone, Jeff Foust.

831
00:44:43,580 --> 00:44:44,331
Space news.

832
00:44:45,933 --> 00:44:46,600
Good morning.

833
00:44:46,600 --> 00:44:49,670
Quick question on the leak rates
that you measured.

834
00:44:49,670 --> 00:44:53,457
Was that that low week rate, that 1.5%
or so constant

835
00:44:53,457 --> 00:44:56,777
throughout the test from from fueling
through the terminal count down?

836
00:44:56,777 --> 00:45:00,481
Or were there points in the test
that that leak peaked?

837
00:45:00,481 --> 00:45:03,050
And is that providing
any sort of diagnostics about

838
00:45:03,050 --> 00:45:06,870
what might have been the root cause
of, of the issues you were having earlier?

839
00:45:06,870 --> 00:45:08,639
Thanks.

840
00:45:08,639 --> 00:45:08,839
Yeah.

841
00:45:08,839 --> 00:45:11,358
So no, it was not, constantly grade.

842
00:45:11,358 --> 00:45:16,797
In fact, I don't have the
I just had the max, leak rate

843
00:45:16,797 --> 00:45:20,751
for during our FIL operations,
and it was, I'm going to say

844
00:45:20,751 --> 00:45:25,022
this, 0.4% was our max

845
00:45:25,022 --> 00:45:28,308
in, fast fail, 0.4%.

846
00:45:28,826 --> 00:45:31,528
So, that is almost unheard of.

847
00:45:31,528 --> 00:45:35,699
Even in Artemis one,
we did not see leak rates that low.

848
00:45:37,067 --> 00:45:37,918
The,

849
00:45:37,918 --> 00:45:41,822
leak rate in
term count we saw was, in the first run

850
00:45:41,822 --> 00:45:45,175
through term count,
we had 1.6% was the highest we saw.

851
00:45:45,542 --> 00:45:50,631
And, in our second one,
it was, 0.7, and,

852
00:45:50,631 --> 00:45:53,934
it was not constant the whole time,
because what happens in term count

853
00:45:54,201 --> 00:45:56,386
is that we're going through
something called pre-press.

854
00:45:56,386 --> 00:46:00,808
And so you have these, pressurization
pulses that, that are being sent

855
00:46:00,808 --> 00:46:02,242
to pressurize the flight tank.

856
00:46:02,242 --> 00:46:05,779
And so you could see that you'll see
some fluctuation in that leak rate.

857
00:46:05,779 --> 00:46:09,633
But the numbers that I gave
is the max that we saw, during that time.

858
00:46:09,633 --> 00:46:12,619
So, again,
very good performance yesterday.

859
00:46:14,071 --> 00:46:17,074
CNN.

860
00:46:17,941 --> 00:46:18,475
Hi, folks.

861
00:46:18,475 --> 00:46:19,409
Thanks for doing this.

862
00:46:19,409 --> 00:46:20,461
Couple questions.

863
00:46:20,461 --> 00:46:22,713
First for, Charlie about the Seals.

864
00:46:22,713 --> 00:46:26,300
What's what's the difference
between the Seals,

865
00:46:26,300 --> 00:46:29,486
that you just put on versus
the one that were replaced?

866
00:46:29,486 --> 00:46:33,240
You know, if I understand correctly,
these work with the chill down.

867
00:46:33,240 --> 00:46:36,410
So what makes you confident
that these seals, you know,

868
00:46:36,410 --> 00:46:39,863
won't continue to work, 
with chilled out on launch day?

869
00:46:40,848 --> 00:46:42,833
And then question for whoever can take it.

870
00:46:42,833 --> 00:46:44,485
I know that there was an indication

871
00:46:44,485 --> 00:46:47,521
that you could work towards an earlier
launch date than March 6th.

872
00:46:47,521 --> 00:46:49,623
I think March 3rd was kicked around.

873
00:46:49,623 --> 00:46:52,743
Can you discuss
why you were able to evaluate launch dates

874
00:46:52,743 --> 00:46:54,261
that weren't previously identified

875
00:46:54,261 --> 00:46:57,264
and why you ultimately decided
to stick with March 6th?

876
00:46:57,598 --> 00:47:01,468
And are you going to continue to consider
maybe alternative launch days

877
00:47:01,468 --> 00:47:02,219
down the line,

878
00:47:02,219 --> 00:47:05,489
or is it pretty much set to these
that you've previously identified now?

879
00:47:05,689 --> 00:47:08,192
Thanks so much.

880
00:47:08,192 --> 00:47:11,578
Yes. I'll take the first part of the
I don't own the seals.

881
00:47:11,712 --> 00:47:14,698
There's no difference.

882
00:47:14,882 --> 00:47:17,718
The seals are exactly the same.

883
00:47:17,718 --> 00:47:20,721
They're just newer seals.

884
00:47:22,472 --> 00:47:25,976
All I can say about that is, is, you know,
these seals are installed

885
00:47:25,976 --> 00:47:30,631
when we build the
core stage, up in the VAB

886
00:47:31,615 --> 00:47:34,051
is Charlie mentioned earlier,

887
00:47:34,051 --> 00:47:36,837
and as you know, we're in the VAB

888
00:47:36,837 --> 00:47:40,190
for pretty good while
because we got a lot of work to do there.

889
00:47:40,190 --> 00:47:44,027
And then we go through rollout and,
and we understand,

890
00:47:44,828 --> 00:47:47,097
that we do have certain loads

891
00:47:47,097 --> 00:47:50,100
on the, on the rocket
as we roll to the pad.

892
00:47:50,934 --> 00:47:53,670
And so I'm not going to speculate anymore.

893
00:47:53,670 --> 00:47:56,874
What I said earlier is we're going
to let the teams go off

894
00:47:56,874 --> 00:47:59,877
and look at the data that we got over this

895
00:47:59,993 --> 00:48:02,029
over the day yesterday

896
00:48:02,029 --> 00:48:05,065
and see how that addresses things

897
00:48:05,065 --> 00:48:08,118
that we might need to do
different moving down the road or

898
00:48:09,353 --> 00:48:11,371
maybe, maybe we just

899
00:48:11,371 --> 00:48:14,358
look at operationally
if we do something different.

900
00:48:16,009 --> 00:48:18,145
And I'll take the question about the,

901
00:48:18,145 --> 00:48:21,949
additional potential
launch opportunity dates.

902
00:48:21,949 --> 00:48:26,403
So as I mentioned, a little bit earlier
when we were talking

903
00:48:26,403 --> 00:48:31,525
about other potential windows,
or launch periods beyond April,

904
00:48:31,858 --> 00:48:35,846
there's an enormous amount of analyzes
that has to go in to,

905
00:48:36,029 --> 00:48:39,983
determination of which of the
which of those dates, actually have,

906
00:48:39,983 --> 00:48:43,520
appropriate launch windows that we can use
that are, you know, we want something

907
00:48:43,520 --> 00:48:46,890
that's in general,
at least two hours, in duration

908
00:48:46,890 --> 00:48:50,577
so that we can, have a good chance
of getting off with on that date.

909
00:48:51,511 --> 00:48:54,498
And then all of the constraints
I mentioned, thermal control,

910
00:48:54,498 --> 00:48:58,135
eclipses for power, communications.

911
00:48:58,585 --> 00:49:01,254
And so what, what we had

912
00:49:01,254 --> 00:49:04,741
done, with March 3rd,
which we had been looking at,

913
00:49:04,741 --> 00:49:09,413
is that the preliminary analysis,
was kind of on the edge.

914
00:49:09,413 --> 00:49:11,598
And so it was originally
taken off of the plate,

915
00:49:11,598 --> 00:49:13,283
and we already knew that the fourth

916
00:49:13,283 --> 00:49:16,286
and the fifth were not viable at all
for some of those reasons.

917
00:49:16,853 --> 00:49:20,040
And so there wasn't a whole lot of,
the additional work

918
00:49:20,040 --> 00:49:22,259
wasn't really done on third on the third.

919
00:49:22,259 --> 00:49:23,310
But,

920
00:49:23,310 --> 00:49:28,198
we started really sharpening our pencils,
trying to maximize the number of days.

921
00:49:28,198 --> 00:49:32,519
Can we eke out, could we eke out
another day in March that could be viable?

922
00:49:32,836 --> 00:49:36,123
And so that in particular,
the Orion team went off and started

923
00:49:36,123 --> 00:49:40,560
looking at it, and looking at
not just the, the nominal case

924
00:49:40,560 --> 00:49:43,130
and the baseline case,
but they have to look at all of the off

925
00:49:43,130 --> 00:49:45,983
nominal cases,
all of the potential scenarios that

926
00:49:45,983 --> 00:49:49,936
that we might end up in, 
and how the Orion spacecraft

927
00:49:49,936 --> 00:49:53,657
would, would still be able to perform,
keep our crew safe,

928
00:49:53,940 --> 00:49:58,428
and be able to return back to Earth,
in a, in a safe configuration.

929
00:49:58,979 --> 00:50:01,581
And so that took an enormous amount
of work, but they went and they did that.

930
00:50:01,581 --> 00:50:04,418
They did all of that,
additional analyzes.

931
00:50:04,418 --> 00:50:07,971
They ultimately did determine that
the third could have been a viable date.

932
00:50:07,971 --> 00:50:12,592
But the work that we had ahead of us, it
it it just didn't seem feasible.

933
00:50:13,043 --> 00:50:16,463
If particularly following Wet dress one
and considering the work

934
00:50:16,463 --> 00:50:20,267
that needed to be done, with replacing
the seals and replacing the filter,

935
00:50:20,467 --> 00:50:25,255
and so we, we opted to eliminate that,
as a, as an available date.

936
00:50:25,555 --> 00:50:30,711
But I anticipate, as we go through the,
the systematic approach that we have

937
00:50:30,711 --> 00:50:34,014
for assessing each of the viable
or the available launch dates.

938
00:50:34,014 --> 00:50:35,282
We'll go through those.

939
00:50:35,282 --> 00:50:38,552
We already have,
I believe a rough cut at those for,

940
00:50:38,552 --> 00:50:40,137
for May and June and beyond.

941
00:50:40,137 --> 00:50:41,988
But we'll continue to refine those.

942
00:50:41,988 --> 00:50:45,292
And as I said earlier, as we as
we sharpen our pencils

943
00:50:45,292 --> 00:50:46,793
and we start to get a better understanding

944
00:50:46,793 --> 00:50:49,129
of exactly
which of those dates are available,

945
00:50:49,129 --> 00:50:51,715
we'll make those available to you guys
as well.

946
00:50:51,715 --> 00:50:53,450
We're saying on the phones,
we have quite a bit there.

947
00:50:53,450 --> 00:50:54,801
Steven Clark, Ars Technica.

948
00:50:58,371 --> 00:50:59,973
Hi, thanks for taking my question.

949
00:50:59,973 --> 00:51:03,410
I don't I think I just answered my
my main question, but I'll follow up,

950
00:51:03,410 --> 00:51:06,680
on the seals, what are the seals made of?

951
00:51:06,680 --> 00:51:07,831
What material?

952
00:51:07,831 --> 00:51:12,452
And, remind me, was there any difference
between, third design change made in

953
00:51:12,452 --> 00:51:17,791
the seals themselves between Artemis
one and to, that's for for John, I guess.

954
00:51:17,791 --> 00:51:19,743
And for Charlie. We heard some things.

955
00:51:19,743 --> 00:51:22,729
You mentioned the comms issue
during the countdown and also the,

956
00:51:22,979 --> 00:51:27,234
booster avionics issue that came up during
the terminal count, I guess yesterday.

957
00:51:27,717 --> 00:51:31,021
Can you kind of just go over,
you know what the path forward

958
00:51:31,021 --> 00:51:34,007
is on resolving those? Thanks.

959
00:51:34,374 --> 00:51:37,461
So it's a metallic ring
that that fits between

960
00:51:37,461 --> 00:51:40,464
the two interfaces in the metallic rings.

961
00:51:40,947 --> 00:51:44,701
Has the sealing, material built up on it.

962
00:51:45,602 --> 00:51:49,489
It's Teflon,
and then it's kind of a complex

963
00:51:50,006 --> 00:51:52,676
geometry to the spring because it's got,

964
00:51:52,676 --> 00:51:57,714
it's got as a spring assist feature to it
all around, all around the seal.

965
00:51:57,714 --> 00:51:58,131
And then

966
00:51:59,132 --> 00:52:01,134
even, I believe it's the

967
00:52:01,134 --> 00:52:04,971
four inch seal
is actually a pressure assisted seal. So.

968
00:52:05,639 --> 00:52:08,575
But no, there's been no change
since Artemis

969
00:52:08,575 --> 00:52:11,578
one in the design.

970
00:52:13,680 --> 00:52:14,030
Okay.

971
00:52:14,030 --> 00:52:17,033
Joey Roulette, Reuters.

972
00:52:19,069 --> 00:52:20,420
I had a quick question

973
00:52:20,420 --> 00:52:24,407
on the communications issues
that was mentioned earlier on this call.

974
00:52:24,524 --> 00:52:29,062
I know it's not an exciting thing
that happened, but I'm just curious

975
00:52:29,062 --> 00:52:33,033
to know what was causing that, what
the fix was, what the situation is there.

976
00:52:33,033 --> 00:52:35,302
Thank you.

977
00:52:35,302 --> 00:52:36,503
Yes, I can take that.

978
00:52:36,503 --> 00:52:41,391
We did experience
a, communications issue yesterday.

979
00:52:41,391 --> 00:52:45,979
We were able to track it down
to a, network configuration issue.

980
00:52:45,979 --> 00:52:46,730
And so we've been able

981
00:52:46,730 --> 00:52:50,867
to take corrective actions to ensure
that we don't have that happen again.

982
00:52:51,168 --> 00:52:54,538
One thing I'll also say
is that we were able to go through

983
00:52:54,538 --> 00:52:58,942
while it wasn't planned to demonstrate
yesterday, we did go through,

984
00:52:59,142 --> 00:53:04,731
a contingency procedure that we run
in the event that we have a loss of calm.

985
00:53:04,731 --> 00:53:07,701
And, we implemented that yesterday.

986
00:53:07,701 --> 00:53:08,752
It worked great.

987
00:53:08,752 --> 00:53:13,139
The only, slight hold up
that we had was, when the comm issue,

988
00:53:14,107 --> 00:53:16,159
we encountered it, it was just as

989
00:53:16,159 --> 00:53:19,379
we were getting ready to take hydrogen
from slow fill to fast fill.

990
00:53:19,379 --> 00:53:22,048
And, I did ask the team to hold up.

991
00:53:22,048 --> 00:53:23,066
I didn't want to go too fast.

992
00:53:23,066 --> 00:53:26,069
Fill, until we had, stable comm.

993
00:53:26,219 --> 00:53:28,855
Just because in the event
that we were to have something happen,

994
00:53:28,855 --> 00:53:31,374
I wanted to make sure that we could
communicate across our team.

995
00:53:31,374 --> 00:53:34,711
But we do have a contingency plan
that involves,

996
00:53:34,711 --> 00:53:38,281
test nets on our radios,
that we utilize.

997
00:53:38,281 --> 00:53:41,401
And so we did go through and deploy
those yesterday in the firing room.

998
00:53:41,668 --> 00:53:46,523
And we were able to to keep communication
with our team, while the,

999
00:53:46,523 --> 00:53:50,043
the comm network team was able
to go troubleshoot and isolate the,

1000
00:53:50,460 --> 00:53:53,630
the problem, and get us back to stable.

1001
00:53:55,131 --> 00:53:55,649
Okay.

1002
00:53:55,649 --> 00:53:56,366
Cool.

1003
00:53:56,366 --> 00:53:58,585
From the Canadian broadcast
company is on the phone.

1004
00:53:58,585 --> 00:54:00,537
Go ahead and call.

1005
00:54:00,537 --> 00:54:02,038
Actually, that was my question.

1006
00:54:02,038 --> 00:54:05,191
I was going to ask about the, 
comms issue.

1007
00:54:05,759 --> 00:54:09,562
But, I mean, you seem pretty confident
that this won't creep up again.

1008
00:54:09,562 --> 00:54:15,185
I'm asking because this also occurred
during, the first attempt

1009
00:54:15,201 --> 00:54:17,370
with Artemis one.

1010
00:54:17,370 --> 00:54:20,357
Had you changed anything
since then with comms?

1011
00:54:23,126 --> 00:54:26,062
An issue like this during Artemis one?

1012
00:54:26,062 --> 00:54:29,899
I do not recall any issues that we had

1013
00:54:29,899 --> 00:54:33,053
like this with the communication system
during Artemis one.

1014
00:54:33,503 --> 00:54:36,406
We had a different comms system,

1015
00:54:36,406 --> 00:54:39,559
during Artemis one
than the one that we have in place today.

1016
00:54:39,859 --> 00:54:42,629
And, I don't I don't recall any,

1017
00:54:42,629 --> 00:54:45,632
communication issues during Artemis one.

1018
00:54:46,700 --> 00:54:48,118
Okay, let's see,
there are new hands in the room

1019
00:54:48,118 --> 00:54:50,487
because we still have quite a bit
on the phone. We'll go here.

1020
00:54:52,639 --> 00:54:54,174
And then we'll go back to the phones.

1021
00:54:54,174 --> 00:54:56,576
I, verdict
with the National Space Society.

1022
00:54:56,576 --> 00:54:58,261
A question for a John.

1023
00:54:58,261 --> 00:54:59,929
At the pre rollover

1024
00:54:59,929 --> 00:55:03,867
press conference, you mentioned
the enormous responsibility of the MMT

1025
00:55:04,100 --> 00:55:06,603
and that we're not going to be going to
we're ready.

1026
00:55:06,603 --> 00:55:08,905
We've made a lot of progress since then.

1027
00:55:08,905 --> 00:55:09,656
I'm just wondering,

1028
00:55:09,656 --> 00:55:13,410
as we're moving toward launch,
what will you be looking at specifically?

1029
00:55:13,643 --> 00:55:17,130
Is there anything that maybe, concerns you
or is keeping you up at night?

1030
00:55:18,832 --> 00:55:21,835
No. Are you talking
relative to the MMT or the hardware

1031
00:55:23,386 --> 00:55:24,504
to the MMT?

1032
00:55:24,504 --> 00:55:24,921
Yeah.

1033
00:55:24,921 --> 00:55:28,224
So, you know, we did talk we looked at it.

1034
00:55:28,224 --> 00:55:32,779
And I think the leadership leadership
above me agreed at some point

1035
00:55:32,779 --> 00:55:35,932
in time in this, path

1036
00:55:35,999 --> 00:55:39,052
today, we needed to do more to get ready.

1037
00:55:40,253 --> 00:55:43,256
I feel
like at this point we have demonstrated,

1038
00:55:43,707 --> 00:55:46,192
a significant amount

1039
00:55:46,192 --> 00:55:49,195
of improvement to where I am almost happy.

1040
00:55:49,529 --> 00:55:52,248
And, I may not ever be happy.

1041
00:55:52,248 --> 00:55:55,769
I don't know, but I'll tell you, we got,

1042
00:55:56,720 --> 00:55:59,039
we have another sim, in space

1043
00:55:59,039 --> 00:56:03,476
SIM planned at JSC for the MMT on Monday.

1044
00:56:04,127 --> 00:56:07,130
And then,

1045
00:56:07,497 --> 00:56:10,283
you know, knock on wood, we want it.

1046
00:56:10,283 --> 00:56:13,970
We want to go fly
as soon as we can in the launch window.

1047
00:56:13,970 --> 00:56:18,958
But if if something opens up there
and God forbid that to happen,

1048
00:56:19,059 --> 00:56:22,562
I'll be looking at all of the things
we can go do to stay sharp.

1049
00:56:23,997 --> 00:56:24,230
All right.

1050
00:56:24,230 --> 00:56:25,982
We have time for two more on the phone.

1051
00:56:25,982 --> 00:56:28,968
Tariq Malik, Space.com.

1052
00:56:30,070 --> 00:56:31,971
This, thank you very much, Charlie.

1053
00:56:31,971 --> 00:56:36,993
You mentioned that during this fueling
test, the, the Artemis two crew,

1054
00:56:37,227 --> 00:56:40,397
you know, they weren't participating,
but that they were observing.

1055
00:56:40,397 --> 00:56:45,802
And I'm just curious kind of what, 
what their, reactions or their,

1056
00:56:45,835 --> 00:56:47,687
their input was
that you've got after the fact

1057
00:56:47,687 --> 00:56:50,690
about what they, what they're thinking
now that we've passed this milestone,

1058
00:56:50,790 --> 00:56:53,843
and that you're,
you've got March 6th on the horizon.

1059
00:56:55,078 --> 00:56:55,345
Yeah.

1060
00:56:55,345 --> 00:57:00,900
So, yeah, we were really lucky to have
our flight crew in the firing room.

1061
00:57:01,134 --> 00:57:03,803
Three of the four members
observing the test.

1062
00:57:03,803 --> 00:57:08,041
And, to say, I would say
that they were excited to be there

1063
00:57:08,041 --> 00:57:12,562
with the team and, and
and pretty pleased with all the results.

1064
00:57:12,562 --> 00:57:15,799
So, you know, I wouldn't
want to put words in their mouth, but,

1065
00:57:15,799 --> 00:57:19,586
I think they were, as happy
or maybe happier than I was.

1066
00:57:19,586 --> 00:57:23,440
And I was certainly thrilled
with the results I read, Reid said in,

1067
00:57:23,440 --> 00:57:27,210
in the MMT bubble, with us.

1068
00:57:27,210 --> 00:57:30,230
And he in particular, he said,

1069
00:57:30,230 --> 00:57:33,233
right next to the moon team,
our chief engineer.

1070
00:57:34,067 --> 00:57:37,170
And, he stayed right there
through to the whole time.

1071
00:57:37,737 --> 00:57:40,440
And, Reid made

1072
00:57:40,440 --> 00:57:43,643
the same observation that I made earlier
today.

1073
00:57:43,643 --> 00:57:48,798
He's he's been either
directly tracking or indirectly tracking

1074
00:57:49,582 --> 00:57:52,135
how this
what this team's doing to improve.

1075
00:57:52,135 --> 00:57:57,540
And he saw that and he noted it, to me
after we finished the test.

1076
00:57:57,540 --> 00:58:00,510
So he reflected on
the launch team and the MMT.

1077
00:58:03,530 --> 00:58:03,947
All right.

1078
00:58:03,947 --> 00:58:07,133
Andrea Lynn Felder, Houston Chronicle,
you have the last question

1079
00:58:07,133 --> 00:58:10,019
of this press briefing. Go ahead.

1080
00:58:10,019 --> 00:58:11,271
I, thank you.

1081
00:58:11,271 --> 00:58:13,940
I wanted to ask another question
about the communications.

1082
00:58:13,940 --> 00:58:17,243
I recall there were communication
blackout during the first

1083
00:58:17,243 --> 00:58:20,246
wet dress rehearsal for the Artemis
two mission.

1084
00:58:20,246 --> 00:58:24,534
And there was an alert, news update
that said it had been an ongoing issue.

1085
00:58:24,534 --> 00:58:27,620
So is there a larger issue
with the communications?

1086
00:58:27,620 --> 00:58:31,708
And, you know, did go into the contingency
contingency plan yesterday, provide

1087
00:58:31,708 --> 00:58:32,909
confidence that, you know,

1088
00:58:32,909 --> 00:58:36,029
that plan would work on launch day
if there was another communications issue.

1089
00:58:36,145 --> 00:58:38,164
Thank you.

1090
00:58:38,164 --> 00:58:39,716
So we did have

1091
00:58:39,716 --> 00:58:43,369
we did have a, a comm issue
during wet dress one.

1092
00:58:43,820 --> 00:58:49,075
And, you know, there's been like many,
like, many communication issues,

1093
00:58:49,075 --> 00:58:52,912
just a reflection of technology,
if you will.

1094
00:58:53,179 --> 00:58:55,348
That can happen
for a lot of different reasons.

1095
00:58:55,348 --> 00:58:58,851
And so the team has been working
very diligently to determine

1096
00:58:58,851 --> 00:59:01,704
as we go through each of them,
and not all of them are the same.

1097
00:59:01,704 --> 00:59:06,242
Sometimes it is related to, 
some of the comm issues can be related

1098
00:59:06,242 --> 00:59:09,379
to, you know, some configuration
between centers.

1099
00:59:09,379 --> 00:59:11,431
And so you may have heard
that we had some of that

1100
00:59:11,431 --> 00:59:15,351
in one of our wet dress, where we had
some of our loops that weren't,

1101
00:59:15,351 --> 00:59:18,805
weren't connected,
in the way that we expected,

1102
00:59:18,805 --> 00:59:21,357
which is why we do wet dress
so we can figure out all these things.

1103
00:59:21,357 --> 00:59:22,642
So on launch day

1104
00:59:22,642 --> 00:59:26,913
that we get all this configuration,
and all of this mapping correctly.

1105
00:59:26,913 --> 00:59:30,333
And so that was one form of the,
the comm issues that we've had.

1106
00:59:30,617 --> 00:59:34,320
We've also had we had another issue,

1107
00:59:34,320 --> 00:59:38,124
on a prior test
where we, we dropped out of what

1108
00:59:38,124 --> 00:59:42,812
was called duplex to simplex,
mode within the server, which is that

1109
00:59:43,279 --> 00:59:47,850
the comm essentially worked just fine,
but the redundancy wasn't there.

1110
00:59:47,850 --> 00:59:50,270
And so you may have heard us
speak about that.

1111
00:59:50,270 --> 00:59:52,789
Yesterday's
issue was something completely different.

1112
00:59:52,789 --> 00:59:56,909
It wasn't within the voice comm
system itself, but it was in the network.

1113
00:59:57,260 --> 01:00:01,347
So hopefully as we have worked our way
through this,

1114
01:00:01,397 --> 01:00:04,584
pinpointing each
and every one of these root causes

1115
01:00:04,584 --> 01:00:07,587
and correcting them, hopefully
on launch day, we don't see this.

1116
01:00:07,854 --> 01:00:11,424
We'll certainly be putting
operational controls in place as well

1117
01:00:11,424 --> 01:00:16,012
for once we get our config in place
and freezing it, once we test it out.

1118
01:00:16,012 --> 01:00:19,282
So there'll be some operational controls
that, that come along with that.

1119
01:00:19,732 --> 01:00:24,203
And was there another part to the o
our backup plan.

1120
01:00:24,203 --> 01:00:29,125
So, you know, because we had some issues
before we wanted with Wet dress one,

1121
01:00:29,942 --> 01:00:34,380
we wanted to make sure that we had,
you know, one of the things that that,

1122
01:00:34,430 --> 01:00:37,650
I think NASA does really well is we,

1123
01:00:37,767 --> 01:00:40,637
you know,
we learn from the data that we're given.

1124
01:00:40,637 --> 01:00:43,856
And, and then you try to take that
and you apply it and you think about,

1125
01:00:43,856 --> 01:00:47,160
well, what could the next failure be
and how would we address that?

1126
01:00:47,543 --> 01:00:50,063
And so we had a comm issue.

1127
01:00:50,063 --> 01:00:53,933
We thought about you know, we went
and corrected the issue that we had,

1128
01:00:53,933 --> 01:00:55,768
and then we thought about, well,
what if this happened

1129
01:00:55,768 --> 01:00:58,021
and what if it happened
in the most dynamic state,

1130
01:00:58,021 --> 01:01:00,390
and what would we do
and how would we address that?

1131
01:01:00,390 --> 01:01:03,393
And that's where the contingency plan
came, came up.

1132
01:01:03,393 --> 01:01:05,044
We had that procedure.

1133
01:01:05,044 --> 01:01:07,046
So it wasn't something we were doing
yesterday.

1134
01:01:07,046 --> 01:01:11,117
We had, radios available
in the firing room.

1135
01:01:11,117 --> 01:01:12,802
We had people designated

1136
01:01:12,802 --> 01:01:16,072
that would be available to provide
those as they were needed.

1137
01:01:16,289 --> 01:01:17,807
We knew what channels we would use.

1138
01:01:17,807 --> 01:01:20,610
It was all in, in our procedures. And so

1139
01:01:21,561 --> 01:01:22,011
while I

1140
01:01:22,011 --> 01:01:25,014
hope to not, execute that on launch day,

1141
01:01:25,164 --> 01:01:28,584
I certainly know that if we need to,
that it is available to us.

1142
01:01:29,035 --> 01:01:29,902
And I do have it.

1143
01:01:29,902 --> 01:01:31,437
I know you said
that was our last question,

1144
01:01:31,437 --> 01:01:33,506
but I want to go back
because I didn't answer.

1145
01:01:33,506 --> 01:01:36,409
I think between the multiple questions,
it got missed.

1146
01:01:36,409 --> 01:01:40,997
But, someone asked about the issue
that stopped us in terminal count

1147
01:01:40,997 --> 01:01:44,751
because we always planned to count down
and hold that a minute.

1148
01:01:44,751 --> 01:01:47,003
30 we did not plan to have an issue.

1149
01:01:47,003 --> 01:01:50,606
We did have an issue
which was, booster powered 001,

1150
01:01:51,474 --> 01:01:55,862
which looks at three sets of it
basically looks at three measurements.

1151
01:01:55,862 --> 01:02:00,750
Two of them are from the ground and one is
from the booster, on board, battery.

1152
01:02:00,750 --> 01:02:01,701
And it's just making sure

1153
01:02:01,701 --> 01:02:06,089
that we have the right, 
voltage, to support the, the mission.

1154
01:02:06,089 --> 01:02:09,442
And so what happened is that the flight
measurement looked great.

1155
01:02:09,442 --> 01:02:10,526
It was solid.

1156
01:02:10,526 --> 01:02:14,580
And we saw a delta to the,
between what the ground side was seeing.

1157
01:02:14,580 --> 01:02:16,799
So, we're going to go
take a look at that.

1158
01:02:16,799 --> 01:02:18,267
It was no constraint to yesterday.

1159
01:02:18,267 --> 01:02:19,218
We're not going to fly.

1160
01:02:19,218 --> 01:02:21,471
And so we knew that
we're in a good position to press on.

1161
01:02:21,471 --> 01:02:22,422
We did that.

1162
01:02:22,422 --> 01:02:26,092
But we will be going and 
looking into that and figuring out why

1163
01:02:26,092 --> 01:02:26,943
we saw that delta

1164
01:02:26,943 --> 01:02:31,247
between the ground, and,
and the flight certainly between the two.

1165
01:02:31,280 --> 01:02:32,298
You want your flight,

1166
01:02:32,298 --> 01:02:35,451
measurement to be sound because that's
the one you're going to go fly with.

1167
01:02:35,451 --> 01:02:37,620
The ground is going to be left behind.

1168
01:02:37,620 --> 01:02:41,507
But, but we'll go work that out
and figure that one out.

1169
01:02:41,507 --> 01:02:45,061
But that was the issue someone asked about
that stopped us in term count yesterday.

1170
01:02:46,012 --> 01:02:47,447
Thank you so much for the follow up.

1171
01:02:47,447 --> 01:02:49,382
Charlie, as you can see,
we try to get to as many of you

1172
01:02:49,382 --> 01:02:50,850
and as many of your questions as possible.

1173
01:02:50,850 --> 01:02:53,069
But we do have to wrap up today's news
conference.

1174
01:02:53,069 --> 01:02:55,438
Now, again,
thank you so much for your questions.

1175
01:02:55,438 --> 01:02:58,291
And thank you, of course, to Lori,
Charlie and John here.

1176
01:02:58,291 --> 01:03:01,611
And as you heard them say,
we are going to target our 1st

1177
01:03:01,611 --> 01:03:04,730
March opportunity, March 6th, pending
any open work.

1178
01:03:04,947 --> 01:03:08,551
But ahead of that attempt will,
of course, host more of these briefings

1179
01:03:08,551 --> 01:03:11,487
so that you can stay up to date
on our progress.

1180
01:03:11,487 --> 01:03:12,138
But until then,

1181
01:03:12,138 --> 01:03:16,142
everyone can learn more about this mission
by going to nasa.gov/artemis

1182
01:03:16,225 --> 01:03:18,261
for pulling that up on the screen
right now.

1183
01:03:18,261 --> 01:03:20,897
Again, NASA.gov slash Artemis again.

1184
01:03:20,897 --> 01:03:22,431
Thank you everyone for your interest,

1185
01:03:22,431 --> 01:03:24,934
for your questions
and have a great rest of your day.
