00:00:00.000 --> 00:00:05.438
(music throughout) On October 20th, 2020, NASA’s OSIRIS-REx spacecraft

2
00:00:05.438 --> 00:00:07.807
collected a sample from asteroid Bennu.

3
00:00:07.807 --> 00:00:11.745
Navigation. Nav is go for TAG.

4
00:00:11.745 --> 00:00:18.485
Program Manager. Program Manager is go for TAG

5
00:00:18.485 --> 00:00:26.159
All stations, this is OREx systems on OREx cord, all subsystems are go for TAG.

6
00:00:26.159 --> 00:00:31.598
Position uncertainty is 0.5 meters

7
00:00:31.598 --> 00:00:35.835
(clapping) predicted TAG lateral offset is 1.7 meters

8
00:00:35.835 --> 00:00:39.239
Hazard probability is zero percent

9
00:00:39.239 --> 00:00:43.877
OSIRIS-REx’s sampling mechanism penetrated Bennu’s regolith

10
00:00:43.877 --> 00:00:50.483
and fired its nitrogen gas bottle to stir up sample material for collection in the TAGSAM head.

11
00:00:50.483 --> 00:00:58.658
At 6:08pm EDT, the team on Earth received confirmation of a successful touchdown.

12
00:00:58.658 --> 00:01:02.095
OREx has descended below the five meter mark

13
00:01:02.095 --> 00:01:03.930
the hazard map is go for TAG

14
00:01:03.930 --> 00:01:17.844
and we have touchdown! (cheering)

15
00:01:17.844 --> 00:01:21.981
After spending approximately 6 seconds at the surface,

16
00:01:21.981 --> 00:01:28.054
OSIRIS-REx fired its thrusters and backed away from sample site Nightingale.





17
00:01:28.054 --> 00:01:34.094
Images taken a few days later by the SamCam camera showed rocks and dust

18
00:01:34.094 --> 00:01:36.529
escaping the sampler head.

19
00:01:36.529 --> 00:01:40.500
The team believed it collected a sufficient sample and decided to seal

20
00:01:40.500 --> 00:01:44.471
the TAGSAM to preserve the remaining material.

21
00:01:44.471 --> 00:01:49.042
The spacecraft made one more flyover of Bennu and saw

22
00:01:49.042 --> 00:01:51.578
just how big a mark it left on the asteroid’s surface.

23
00:01:51.578 --> 00:01:56.416
The TAG event sent boulders flying across Nightingale’s surface.

24
00:01:56.416 --> 00:02:03.256
OSIRIS-REx completed its last flyover of Bennu at around 6 am EDT on April 7th 2021

25
00:02:03.256 --> 00:02:10.330
and slowly began drifting away from the asteroid.

26
00:02:10.330 --> 00:02:15.568
On May 10th, 2021, OSIRIS-REx fired its thrusters

27
00:02:15.568 --> 00:02:29.115
and began its two-year cruise back home to Earth.

28
00:02:29.115 --> 00:02:32.852
As OSIRIS-REx approaches Earth, it will jettison

29
00:02:32.852 --> 00:02:37.490
the Sample Return Capsule that contains pieces from asteroid Bennu.

30
00:02:37.490 --> 00:02:42.061
The SRC will then travel through Earth’s atmosphere

31
00:02:42.061 --> 00:02:54.073
and land under parachutes at the Utah Test and Training Range on September 24, 2023.

32
00:02:54.073 --> 00:03:00.113
Once recovered, the capsule will be transported to the curation facility at NASA’s Johnson Space Center,

33
00:03:00.113 --> 00:03:04.517
where the sample will be removed for distribution to laboratories worldwide,

34
00:03:04.517 --> 00:03:10.590
enabling scientists to study the formation of our Solar System and Earth as a habitable planet.
