00:00:00,334 --> 00:00:05,072
On September 8, 2016 in Cape
Canaveral, Florida, OSIRIS-REx

2
00:00:05,072 --> 00:00:08,876
began its journey – NASA’s most
ambitious sample collection

3
00:00:08,876 --> 00:00:12,679
Attempt since the Apollo
Program. After two years,

4
00:00:12,679 --> 00:00:17,551
including a gravity assist from
Earth, the spacecraft arrived at

5
00:00:17,551 --> 00:00:23,156
its destination, asteroid Bennu.
As OSIRIS-REx drew near, Bennu

6
00:00:23,156 --> 00:00:26,660
grew in detail from a few tiny
pixels to a surprisingly rugged

7
00:00:26,660 --> 00:00:30,564
world, littered with giant
boulders. The spacecraft has

8
00:00:30,564 --> 00:00:35,102
used its instrumentation to map
the asteroid from all sides,

9
00:00:35,102 --> 00:00:39,540
mapping it in unprecedented
detail. The mission team has

10
00:00:39,540 --> 00:00:43,911
been analyzing the data,
scouring Bennu’s surface to

11
00:00:43,911 --> 00:00:48,649
select the best sample site.
Now, with just months to go

12
00:00:48,649 --> 00:00:53,654
before sample collection, the
team has narrowed its target

13
00:00:53,654 --> 00:00:55,673
down to four potential sites.
