WEBVTT FILE 1 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.
