1
00:00:01,768 --> 00:00:03,870
Artemis II is our first crewed mission

2
00:00:03,870 --> 00:00:06,873
back to the Moon since the Apollo program.

3
00:00:07,140 --> 00:00:11,244
A lot of the focus of Artemis
II is really checking out systems to be

4
00:00:11,244 --> 00:00:16,149
sure that we're ready and well positioned
for continued human exploration.

5
00:00:16,850 --> 00:00:20,186
My name is Susan Baggerman,
and I'm the chief health and performance

6
00:00:20,186 --> 00:00:23,223
officer for the Orion program
and the Artemis II mission.

7
00:00:23,223 --> 00:00:26,192
And this is ten days in Orion.

8
00:00:31,931 --> 00:00:35,035
For this mission,
the crew will launch in the Orion

9
00:00:35,035 --> 00:00:39,406
spacecraft on top of the Space
Launch System rocket or the SLS rocket.

10
00:00:39,906 --> 00:00:43,476
Once they've launched and achieved orbit
shortly after that, they'll perform

11
00:00:43,476 --> 00:00:45,278
what's called an apogee raise burn.

12
00:00:45,278 --> 00:00:48,014
And that's basically
to put them into a high Earth orbit,

13
00:00:48,014 --> 00:00:50,550
which is critically important
for this flight,

14
00:00:50,550 --> 00:00:52,652
because it gives the crew 24 hours

15
00:00:52,652 --> 00:00:55,855
where they can orbit
and check out some of the key systems,

16
00:00:55,855 --> 00:00:57,290
but also still be close enough

17
00:00:57,290 --> 00:01:00,160
that we could return them to Earth
if something were to happen.

18
00:01:01,127 --> 00:01:01,995
One of their first

19
00:01:01,995 --> 00:01:05,732
priorities is conducting a rendezvous
and prox ops demonstration.

20
00:01:05,732 --> 00:01:09,903
This is basically just a chance
to check out the Orion handling qualities,

21
00:01:09,903 --> 00:01:13,206
and what it would be like
to dock to another spacecraft.

22
00:01:13,706 --> 00:01:17,744
They'll continue on checking out many
of the different critical Orion systems.

23
00:01:17,777 --> 00:01:21,714
They'll be looking at things
like oxygen levels within the vehicle,

24
00:01:21,748 --> 00:01:25,251
how the CO2 scrubbing system
is performing.

25
00:01:25,285 --> 00:01:29,289
Check out some of the critical medical
systems, and be sure that we understand

26
00:01:29,289 --> 00:01:33,259
how the crew would do that
successfully within the volume of Orion.

27
00:01:34,194 --> 00:01:37,197
We also have,
of course, systems to feed the crew.

28
00:01:37,730 --> 00:01:40,600
They have a potable water
dispenser that they'll check out.

29
00:01:40,600 --> 00:01:42,235
And then we also have a food warmer.

30
00:01:42,235 --> 00:01:45,738
Kind of looks like a suitcase
that the crew can use to heat their food.

31
00:01:46,940 --> 00:01:50,009
They're also
going to check out the flywheel system.

32
00:01:50,043 --> 00:01:53,213
We'll have the crew perform
some initial exercises.

33
00:01:53,213 --> 00:01:56,216
Part of that is to ensure
that the flywheel is actually working,

34
00:01:56,382 --> 00:01:57,550
but part of it is actually

35
00:01:57,550 --> 00:02:01,020
to be sure that our environmental control
systems are actually working.

36
00:02:01,321 --> 00:02:04,457
For sleeping,
the crew will sleep in sleeping bags.

37
00:02:04,557 --> 00:02:09,095
Some crew members like to be very, like,
tightly bound up, and some like to float

38
00:02:09,095 --> 00:02:10,163
very free.

39
00:02:10,163 --> 00:02:13,666
For the most part, they can sleep wherever
they want within the Orion vehicle.

40
00:02:14,100 --> 00:02:17,103
They'll attempt things
that may seem pretty easy to do here

41
00:02:17,103 --> 00:02:20,106
on Earth, but that are much harder
to do with microgravity.

42
00:02:20,206 --> 00:02:23,877
They'll use the toilet for the first time,
and be sure that it's able to flush.

43
00:02:24,844 --> 00:02:25,945
I'm Melissa McKinley.

44
00:02:25,945 --> 00:02:30,150
I'm the project manager for the UWMS,
the universal waste management system.

45
00:02:30,750 --> 00:02:34,154
Going to the bathroom
without the aid of gravity, without water

46
00:02:34,154 --> 00:02:37,023
to collect the waste. It's
harder than you would think.

47
00:02:37,023 --> 00:02:41,728
So we use airflow to help entrain
the waste into packaging to collect it.

48
00:02:41,728 --> 00:02:45,798
And help the crew member
deposit the waste away from their bodies.

49
00:02:46,065 --> 00:02:50,069
It is really important that we make it
easy as we can for crew

50
00:02:50,069 --> 00:02:54,107
and make it comfortable for them,
because it is a vital part of exploration.

51
00:02:56,576 --> 00:02:57,510
I'm Romeo Garza.

52
00:02:57,510 --> 00:03:00,280
I am the deputy system manager
for the Orion communication

53
00:03:00,280 --> 00:03:02,382
and tracking system here at Johnson
Space Center.

54
00:03:02,382 --> 00:03:04,117
While we're in the high Earth orbit,

55
00:03:04,117 --> 00:03:05,785
there's a couple of things
we really want to check out

56
00:03:05,785 --> 00:03:07,921
before we commit
to going all the way to the Moon.

57
00:03:07,921 --> 00:03:11,357
First one is just success in communicating
with the Deep Space Network.

58
00:03:11,391 --> 00:03:14,727
This is a ground network that provides
a lot of capability for us to be able

59
00:03:14,727 --> 00:03:18,031
to tie it back and forth as we go further
and further away from the Earth.

60
00:03:18,698 --> 00:03:21,901
Step two
is checking out our emergency comm system.

61
00:03:22,135 --> 00:03:26,272
The idea is that if the primary system
communication system fails,

62
00:03:26,673 --> 00:03:30,410
this emergency communication system
will be able to allow us to continue

63
00:03:30,410 --> 00:03:34,714
talking with the crew and navigate
successfully without the primary system.

64
00:03:35,582 --> 00:03:38,918
Once the crew is completed
that high Earth orbit and checked out

65
00:03:38,918 --> 00:03:42,455
all of the systems, then we'll commit to
what's called the trans lunar injection.

66
00:03:42,455 --> 00:03:45,458
And this is basically the burn
that commits us to the Moon

67
00:03:45,925 --> 00:03:47,293
while they're on their journey.

68
00:03:47,293 --> 00:03:51,431
They'll do some testing
that they quickly don their suit pressure

69
00:03:51,431 --> 00:03:55,401
check it, and be sure that they're able
to execute that,

70
00:03:55,401 --> 00:03:58,538
just to be sure that we would be ready
in the future for an emergency.

71
00:03:59,272 --> 00:04:02,175
They'll also check out
our radiation shelter.

72
00:04:02,175 --> 00:04:06,546
If we were to have a solar particle event,
we would be asking them to take stowage

73
00:04:06,546 --> 00:04:09,882
out of the stowage bay
and put it in some specific locations

74
00:04:09,882 --> 00:04:12,952
on the vehicle,
basically for it to serve as shielding.

75
00:04:14,687 --> 00:04:15,755
After completing this

76
00:04:15,755 --> 00:04:19,425
journey of over
685,000 miles around the Moon,

77
00:04:19,659 --> 00:04:23,396
the crew will splashdown in the Pacific
Ocean off the coast of San Diego.

78
00:04:24,464 --> 00:04:28,167
They'll be greeted by the Navy,
who will recover the vessel

79
00:04:28,167 --> 00:04:31,170
and most importantly, recover the crew.

80
00:04:32,038 --> 00:04:35,375
This mission has been
an absolute monumental effort

81
00:04:35,375 --> 00:04:39,812
by a large team of people within the human
health and performance area.

82
00:04:40,346 --> 00:04:43,683
All of our efforts,
and all of the engineering

83
00:04:43,683 --> 00:04:47,287
and the medical discipline
that was poured into this mission,

84
00:04:47,553 --> 00:04:51,658
really resulted in being able
to see those four crew members,

85
00:04:51,658 --> 00:04:55,828
our friends, return safely to the Earth
and back to their families.
