00:00:00.934 --> 00:00:05.806
NASA’s OSIRIS-REx spacecraft is
heading to asteroid Bennu...

2
00:00:05.806 --> 00:00:10.811
and back. [music]

3
00:00:10.811 --> 00:00:14.481
[music]

4
00:00:14.481 --> 00:00:16.250
The OSIRIS-REx mission
goal is to study

5
00:00:16.250 --> 00:00:21.255
near-Earth asteroid Bennu and
return a sample to Earth.  

6
00:00:21.255 --> 00:00:25.926
OSIRIS-REx’s launch window opens
September 8, 2016 from Space

7
00:00:25.926 --> 00:00:29.863
Launch Complex 41 at Cape
Canaveral, Florida.

8
00:00:29.863 --> 00:00:39.039
[dramatic music]
[rocket fires]

9
00:00:39.039 --> 00:00:42.376
The spacecraft, nestled
inside a Centaur upper stage,

10
00:00:42.376 --> 00:00:46.680
launches on an Atlas V
rocket with a single
solid rocket booster.

11
00:00:46.680 --> 00:01:00.794
[rocket stops firing]
[dramatic music continues]

12
00:01:00.794 --> 00:01:06.400
The rocket’s first
stage separates...

13
00:01:06.400 --> 00:01:10.571
and then the Centaur upper
stage fires.

14
00:01:10.571 --> 00:01:16.643
The fairings separate
from the rocket...

15
00:01:16.643 --> 00:01:23.016
and the OSIRIS-REx
spacecraft releases from
the Centaur upper stage.

16
00:01:23.016 --> 00:01:30.023
Angled toward the Sun, the
spacecraft deploys its solar
arrays.

17
00:01:30.023 --> 00:01:33.827
Now traveling over
25.000 miles per hour.

18
00:01:33.827 --> 00:01:39.166
OSIRIS-REx escapes Earth’s
gravity...

19
00:01:39.166 --> 00:01:41.735
and begins its cruise toward
asteroid Bennu.

20
00:01:41.735 --> 00:01:46.039
[softer, driving music]

21
00:01:46.039 --> 00:01:48.041
After 23 months, the
spacecraft arrives at

22
00:01:48.041 --> 00:01:53.280
asteroid Bennu in August, 2018.

23
00:01:53.280 --> 00:01:58.251
With its suite of observational
instruments, OSIRIS-REx orbits

24
00:01:58.251 --> 00:02:03.190
the asteroid... studying its
characteristics and mapping its

25
00:02:03.190 --> 00:02:08.962
surface. After four phases of
survey observations, OSIRIS-REx

26
00:02:08.962 --> 00:02:15.302
begins preparations to collect
the sample. In July 2020, after

27
00:02:15.302 --> 00:02:18.905
months of rehearsals and study,
the spacecraft approaches for

28
00:02:18.905 --> 00:02:23.744
sample collection. It slowly
descends to Bennu’s surface at

29
00:02:23.744 --> 00:02:28.215
less than a quarter mile per
hour. With an outstretched arm,

30
00:02:28.215 --> 00:02:32.853
OSIRIS-REx briefly touches the
surface. The touch-and-go sample

31
00:02:32.853 --> 00:02:36.857
acquisition mechanism, TAGSAM,
blows high-pressure nitrogen gas

32
00:02:36.857 --> 00:02:40.894
into the surface rocks and dust,
sending loose asteroid material

33
00:02:40.894 --> 00:02:42.796
up into the TAGSAM head.

34
00:02:42.796 --> 00:02:47.334
[dramatic rise and
fall in the music]

35
00:02:47.334 --> 00:02:52.105
OSIRIS-REx backs away
from Bennu... and stows the

36
00:02:52.105 --> 00:02:55.042
sample in a capsule for its
journey to Earth.

37
00:02:55.042 --> 00:03:02.282
[calm driving music continues]

38
00:03:02.282 --> 00:03:06.987
In March 2021, the window opens
for OSIRIS-REx to depart Bennu.

39
00:03:06.987 --> 00:03:09.556
[music drives harder]

40
00:03:09.556 --> 00:03:15.896
The spacecraft returns to Earth
September 24, 2023 and
jettisons the Sample Return

41
00:03:15.896 --> 00:03:20.067
Capsule. As the spacecraft
leaves Earth, the return capsule

42
00:03:20.067 --> 00:03:25.005
enters the Earth’s atmosphere at
over 27,000 miles per hour,

43
00:03:25.005 --> 00:03:27.007
protected by a heat shield.

44
00:03:27.007 --> 00:03:34.014
[intense friction of heat
shield against atmosphere]
[driving music continues]

45
00:03:34.014 --> 00:03:37.117
A couple miles above the
surface, a parachute deploys...

46
00:03:37.117 --> 00:03:45.025
[parachute deploys
and flutters in the wind]

47
00:03:45.025 --> 00:03:49.029
and the capsule lands
softly in the Utah desert.

48
00:03:49.029 --> 00:03:54.935
[soft thump] [dramatic
music climax]

49
00:03:54.935 --> 00:04:00.207
Bennu’s secrets can now be
investigated for decades
to come.

50
00:04:00.207 --> 00:04:15.956
[soft music finish]
