Bennu 3 00:00:03,033 --> 00:00:05,983 one of Earth’s closest planetary neighbors 4 00:00:05,983 --> 00:00:09,266 an asteroid roughly the height of a skyscraper 5 00:00:09,266 --> 00:00:11,583 a remnant from the dawn of the solar system, 6 00:00:11,583 --> 00:00:14,533 made of carbon-rich rocks and boulders 7 00:00:14,533 --> 00:00:20,466 And since late 2018, the place that NASA’s OSIRIS-REx mission has called home. 8 00:00:20,466 --> 00:00:25,800 When OSIRIS-REx arrived, it began wrapping Bennu in a complex web of observations 9 00:00:25,800 --> 00:00:31,366 starting with a Preliminary Survey of its size, shape, mass, and spin. 10 00:00:31,366 --> 00:00:36,433 On New Year’s Eve, OSIRIS-REx was captured into orbit by Bennu’s miniscule gravity, 11 00:00:36,433 --> 00:00:40,566 making it the smallest world ever to be orbited by a spacecraft. 12 00:00:40,566 --> 00:00:44,800 In early 2019, it broke orbit to conduct a Detailed Survey. 13 00:00:44,800 --> 00:00:49,883 A series of sweeping passes allowed OSIRIS-REx to study geological features 14 00:00:49,883 --> 00:00:52,183 at different latitudes and times of day, 15 00:00:52,183 --> 00:00:56,500 enabling stereo imaging and landmark-based navigation. 16 00:00:56,500 --> 00:01:00,183 During the Detailed Survey, OSIRIS-REx globally mapped Bennu 17 00:01:00,183 --> 00:01:02,500 at only 5cm per pixel, 18 00:01:02,500 --> 00:01:07,766 the highest-resolution of any planetary body, including Earth. 19 00:01:07,766 --> 00:01:13,466 On June 12, the spacecraft entered a new orbit at an altitude of just 680 meters, 20 00:01:13,466 --> 00:01:19,800 setting another record, and establishing a home orbit for the remainder of the mission. 21 00:01:19,800 --> 00:01:24,133 In September, it began Reconnaissance on four candidate sample collection sites: 22 00:01:24,133 --> 00:01:29,583 potential locations on Bennu to touch down and collect a sample later in the mission. 23 00:01:29,583 --> 00:01:33,050 OSIRIS-REx concluded its first year at Bennu back in orbit, 24 00:01:33,050 --> 00:01:37,366 circling the asteroid’s terminator, or boundary between day and night. 25 00:01:37,366 --> 00:01:41,066 Here, outside forces acting on the spacecraft are balanced, 26 00:01:41,066 --> 00:01:44,616 allowing it to orbit within the same plane over time. 27 00:01:44,616 --> 00:01:49,000 Reconnaissance resumed in early 2020, with close flyovers of the primary 28 00:01:49,000 --> 00:01:53,483 sample collection site Nightingale, and the backup site Osprey. 29 00:01:53,483 --> 00:01:59,200 In mid-April, OSIRIS-REx performed the first of two rehearsals prior to sample collection. 30 00:01:59,200 --> 00:02:04,466 It navigated to a predetermined “Checkpoint” about 125 meters above Bennu, 31 00:02:04,466 --> 00:02:10,050 then descended to within 65 meters before backing away. 32 00:02:10,050 --> 00:02:13,633 After the Checkpoint rehearsal, OSIRIS-REx flew one final 33 00:02:13,633 --> 00:02:16,283 Reconnaissance sortie over site Osprey. 34 00:02:16,283 --> 00:02:18,650 Then, it made a series of high-altitude maneuvers 35 00:02:18,650 --> 00:02:20,666 while rebooting its onboard processor, 36 00:02:20,666 --> 00:02:24,200 and preparing for its second rehearsal of the sample collection event. 37 00:02:24,200 --> 00:02:27,216 ♪♪♪ 38 00:02:27,216 --> 00:02:32,200 On August 11, OSIRIS-REx departed its home orbit and made a four-hour traverse 39 00:02:32,200 --> 00:02:36,350 to Bennu’s northern hemisphere, retracing its earlier path. 40 00:02:36,350 --> 00:02:39,616 After performing the Checkpoint engine burn to begin its descent, 41 00:02:39,616 --> 00:02:43,783 it made a second engine burn called “Matchpoint” to match Bennu’s rotation, 42 00:02:43,783 --> 00:02:48,583 before backing away at an altitude of approximately 40 meters. 43 00:02:48,583 --> 00:02:53,333 Now, the most crucial moment of the mission had arrived. 44 00:02:53,333 --> 00:02:58,633 On October 20, 2020, at approximately 11:30 am Mountain Time, 45 00:02:58,633 --> 00:03:00,783 the spacecraft departed orbit. 46 00:03:00,783 --> 00:03:04,650 A few hours before, mission controllers on Earth had sent the commands 47 00:03:04,650 --> 00:03:08,250 for the Touch-And-Go sample collection maneuver, or TAG. 48 00:03:08,250 --> 00:03:10,083 As they watched with anticipation, 49 00:03:10,083 --> 00:03:13,300 OSIRIS-REx steered itself to sample site Nightingale, 50 00:03:13,300 --> 00:03:17,766 maneuvering toward the small crater at the walking pace of a spider. 51 00:03:17,766 --> 00:03:21,300 At 4:11 pm, the mission received confirmation: 52 00:03:21,300 --> 00:03:25,600 OSIRIS-REx had touched down and collected its sample. 53 00:03:25,600 --> 00:03:30,150 Following TAG, the spacecraft drifted to a safe distance away from Bennu. 54 00:03:30,150 --> 00:03:33,166 By the end of October, mission controllers determined that it had 55 00:03:33,166 --> 00:03:37,583 exceeded its goal of collecting 60 grams of asteroid material. 56 00:03:37,583 --> 00:03:41,600 They directed it to stow the sample in preparation for return to Earth. 57 00:03:41,600 --> 00:03:45,900 Before departing Bennu, OSIRIS-REx was given one final task. 58 00:03:45,900 --> 00:03:48,533 On April 7, it flew over site Nightingale 59 00:03:48,533 --> 00:03:52,450 to observe how the sample collection event had changed the surface. 60 00:03:52,450 --> 00:03:56,216 And with that, OSIRIS-REx had recorded its mark on Bennu 61 00:03:56,216 --> 00:03:58,216 and spun the last strand of its web. 62 00:03:58,216 -->
