1
00:00:00,467 --> 00:00:01,267
>> You're a go to proceed

2
00:00:01,267 --> 00:00:02,001
with terminal count

3
00:00:02,001 --> 00:00:04,137
and launch of Artemis I.

4
00:00:04,137 --> 00:00:06,506
>> Go for launch.

5
00:00:06,506 --> 00:00:07,841
>> For the Artemis generation,

6
00:00:07,841 --> 00:00:09,175
this is for you.

7
00:00:09,175 --> 00:00:10,810
At this time, I give you a go

8
00:00:10,810 --> 00:00:12,112
to resume count

9
00:00:12,112 --> 00:00:14,981
and launch Artemis I.

10
00:00:14,981 --> 00:00:20,720
>> Three, two, one!

11
00:00:20,720 --> 00:00:23,056
>> And liftoff of Artemis I.

12
00:00:34,768 --> 00:00:37,904
>> On November 16, 2022,

13
00:00:37,904 --> 00:00:39,539
NASA's Artemis I mission

14
00:00:39,539 --> 00:00:42,609
began a new era of space flight,

15
00:00:42,609 --> 00:00:43,610
testing systems

16
00:00:43,610 --> 00:00:44,377
that will take humans

17
00:00:44,377 --> 00:00:47,781
back to the moon and beyond.

18
00:00:52,218 --> 00:00:53,386
The space launch system

19
00:00:53,386 --> 00:00:55,054
built for Artemis I is

20
00:00:55,054 --> 00:00:57,123
the most powerful rocket

21
00:00:57,123 --> 00:00:59,492
in the world.

22
00:00:59,492 --> 00:01:01,361
Just how big is it?

23
00:01:01,361 --> 00:01:02,495
The Artemis rocket system

24
00:01:02,495 --> 00:01:05,899
reaches a height of 322 feet.

25
00:01:05,899 --> 00:01:07,133
That's taller than

26
00:01:07,133 --> 00:01:08,768
the Statue of Liberty.

27
00:01:08,768 --> 00:01:10,036
And it weighs an astounding

28
00:01:10,036 --> 00:01:14,607
5.75 million pounds.

29
00:01:14,607 --> 00:01:16,443
That's like launching the weight

30
00:01:16,443 --> 00:01:20,146
of 450 elephants into space.

31
00:01:22,415 --> 00:01:23,883
It takes a powerful system

32
00:01:23,883 --> 00:01:25,518
of engines and boosters

33
00:01:25,518 --> 00:01:27,220
to get this massive rocket

34
00:01:27,220 --> 00:01:28,588
into the air

35
00:01:28,588 --> 00:01:30,723
and to propel the Orion capsule

36
00:01:30,723 --> 00:01:32,659
all the way to the moon.

37
00:01:32,659 --> 00:01:34,794
>> Three, two, one, fire.

38
00:01:34,794 --> 00:01:36,362
>> Two solid rocket boosters

39
00:01:36,362 --> 00:01:37,831
burn about six tons

40
00:01:37,831 --> 00:01:39,933
of solid propellant each second

41
00:01:39,933 --> 00:01:41,267
to help lift the rocket

42
00:01:41,267 --> 00:01:47,073
off the launch pad.

43
00:01:47,073 --> 00:01:48,174
Assisting the boosters

44
00:01:48,174 --> 00:01:49,309
are four engines

45
00:01:49,309 --> 00:01:52,078
at the base of the core stage,

46
00:01:52,078 --> 00:01:53,146
which burn out more than

47
00:01:53,146 --> 00:01:55,114
1,500 gallons of

48
00:01:55,114 --> 00:01:59,686
liquid propellant each second.

49
00:01:59,686 --> 00:02:00,753
Above the core stage

50
00:02:00,753 --> 00:02:05,024
is the Orion spacecraft.

51
00:02:05,024 --> 00:02:06,159
The launch abort systems

52
00:02:06,159 --> 00:02:07,427
is a protection system

53
00:02:07,427 --> 00:02:10,997
for the crew during launch.

54
00:02:10,997 --> 00:02:12,198
The Orion crew module

55
00:02:12,198 --> 00:02:13,600
is where astronauts will go

56
00:02:13,600 --> 00:02:15,468
in future missions.

57
00:02:15,468 --> 00:02:17,570
Artemis I is an uncrewed test,

58
00:02:17,570 --> 00:02:18,471
meaning no humans

59
00:02:18,471 --> 00:02:20,974
are onboard this time.

60
00:02:20,974 --> 00:02:22,408
The service module contains

61
00:02:22,408 --> 00:02:24,577
Orion's propulsion system,

62
00:02:24,577 --> 00:02:25,512
a single engine

63
00:02:25,512 --> 00:02:26,913
that will provide the spacecraft

64
00:02:26,913 --> 00:02:29,382
almost 25,000 pounds of thrust

65
00:02:29,382 --> 00:02:30,984
as it sends the spacecraft

66
00:02:30,984 --> 00:02:34,020
to the moon.

67
00:02:35,321 --> 00:02:36,489
Liftoff happens once

68
00:02:36,489 --> 00:02:38,057
the core stage engines start

69
00:02:38,057 --> 00:02:38,992
and the solid rocket

70
00:02:38,992 --> 00:02:42,061
boosters ignite.

71
00:02:44,130 --> 00:02:45,899
The rocket rapidly gains speed

72
00:02:45,899 --> 00:02:47,800
as it lights up the sky.

73
00:02:47,800 --> 00:02:49,302
>> And here we go.

74
00:02:49,302 --> 00:02:50,503
And hydrogen burn off

75
00:02:50,503 --> 00:02:52,238
igniters initiate.

76
00:02:52,238 --> 00:02:55,875
Seven, six, five, four --

77
00:02:55,875 --> 00:02:57,377
stage engines start --

78
00:02:57,377 --> 00:02:59,746
three, two, one.

79
00:02:59,746 --> 00:03:01,848
Boosters ignite.

80
00:03:01,848 --> 00:03:03,950
And liftoff of Artemis I.

81
00:03:03,950 --> 00:03:05,585
We rise together,

82
00:03:05,585 --> 00:03:08,388
back to the moon and beyond.

83
00:03:29,309 --> 00:03:30,176
>> About two minutes

84
00:03:30,176 --> 00:03:31,044
into the flight,

85
00:03:31,044 --> 00:03:31,978
the rocket releases

86
00:03:31,978 --> 00:03:34,681
the two solid rocket boosters.

87
00:03:34,681 --> 00:03:35,615
>> Standing by for

88
00:03:35,615 --> 00:03:36,816
solid rocket booster jettison

89
00:03:36,816 --> 00:03:41,788
and shortly thereafter.

90
00:03:43,856 --> 00:03:47,026
>> Their job is complete.

91
00:03:47,026 --> 00:03:48,027
>> Confirmation that

92
00:03:48,027 --> 00:03:48,995
the solid rocket boosters

93
00:03:48,995 --> 00:03:50,496
have separated.

94
00:03:50,496 --> 00:03:51,598
>> Shortly after,

95
00:03:51,598 --> 00:03:52,699
the launch abort system

96
00:03:52,699 --> 00:03:53,499
is released from

97
00:03:53,499 --> 00:03:57,470
the top of the crew module.

98
00:03:57,470 --> 00:03:58,838
The core stage and its engines

99
00:03:58,838 --> 00:03:59,472
continue to

100
00:03:59,472 --> 00:04:00,607
propel the spacecraft

101
00:04:00,607 --> 00:04:04,377
over 17,000 miles per hour.

102
00:04:04,377 --> 00:04:08,581
And then they too separate.

103
00:04:08,581 --> 00:04:09,582
With a final push,

104
00:04:09,582 --> 00:04:10,450
the single engine

105
00:04:10,450 --> 00:04:11,818
of the interim cryogenic

106
00:04:11,818 --> 00:04:13,286
propulsion stage

107
00:04:13,286 --> 00:04:16,990
thrusts Orion onto the moon.

108
00:04:16,990 --> 00:04:18,458
The propulsion stage separates

109
00:04:18,458 --> 00:04:20,593
two hours into the flight,

110
00:04:20,593 --> 00:04:22,662
leaving Orion on its own

111
00:04:22,662 --> 00:04:25,198
for the remaining journey.

112
00:04:25,198 --> 00:04:26,666
It took Orion several days

113
00:04:26,666 --> 00:04:27,867
to get to the moon,

114
00:04:27,867 --> 00:04:28,635
where it remained

115
00:04:28,635 --> 00:04:30,036
in distant orbit

116
00:04:30,036 --> 00:04:32,972
for almost a week.

117
00:04:36,709 --> 00:04:37,677
Then the spacecraft began

118
00:04:37,677 --> 00:04:40,213
its long journey home to Earth,

119
00:04:40,213 --> 00:04:41,948
where it faces the final test

120
00:04:41,948 --> 00:04:43,149
of the mission,

121
00:04:43,149 --> 00:04:47,620
re-entering Earth's atmosphere.

122
00:04:47,620 --> 00:04:48,955
Orion returns to the planet

123
00:04:48,955 --> 00:04:51,758
traveling 25,000 miles per hour,

124
00:04:51,758 --> 00:04:53,292
enduring temperatures nearly

125
00:04:53,292 --> 00:04:55,895
5,000 degrees Fahrenheit.

126
00:04:55,895 --> 00:04:57,430
A series of parachutes deploy

127
00:04:57,430 --> 00:04:58,531
to bring its speed down

128
00:04:58,531 --> 00:05:00,800
to close to 20 miles per hour,

129
00:05:00,800 --> 00:05:02,969
so it can safely splash down

130
00:05:02,969 --> 00:05:07,073
into the Pacific Ocean.

131
00:05:07,073 --> 00:05:10,143
Artemis I was an historic step

132
00:05:10,143 --> 00:05:11,344
in sending humans

133
00:05:11,344 --> 00:05:16,582
back to the moon and beyond,

134
00:05:16,582 --> 00:05:18,484
taking the Artemis generation

135
00:05:18,484 --> 00:05:22,388
further than ever before.
