1 00:00:00,717 --> 00:00:04,771 OSIRIS-REx continues the amazing legacy of exploring the solar system 2 00:00:04,771 --> 00:00:06,239 through sample return. 3 00:00:06,239 --> 00:00:09,509 We started out with the Apollo missions, where we had astronauts 4 00:00:09,509 --> 00:00:13,580 on the surface of the Moon, collecting a wide range of materials which provided 5 00:00:13,580 --> 00:00:17,634 unprecedented insights into the formation of our closest neighbor in space. 6 00:00:18,318 --> 00:00:21,871 We've seen comet dust returned from the Stardust mission 7 00:00:22,172 --> 00:00:25,592 and asteroid particles returned by two Japanese missions, 8 00:00:25,592 --> 00:00:29,629 Hayabusa and Hayabusa2, and OSIRIS-REx goes beyond 9 00:00:29,629 --> 00:00:33,033 those other missions, especially Stardust and the Hayabusa programs, 10 00:00:33,233 --> 00:00:37,020 by bringing back a lot of sample. We're bringing back, we estimate, 11 00:00:37,020 --> 00:00:40,940 about 250 grams of material, about the size of a coffee cup 12 00:00:40,940 --> 00:00:44,310 full of this precious, pristine, carbonaceous asteroid 13 00:00:44,310 --> 00:00:45,328 sample. 14 00:00:47,547 --> 00:00:50,517 The OSIRIS-REx spacecraft is currently on its way 15 00:00:50,517 --> 00:00:55,171 back to Earth right now. On September 24th, 2023, 16 00:00:55,488 --> 00:00:58,408 it will release the sample return capsule 17 00:00:58,408 --> 00:01:01,227 and that will land in the Utah desert. 18 00:01:01,578 --> 00:01:05,482 We will go out into the field, get the sample, 19 00:01:05,698 --> 00:01:09,269 take some soil samples and air samples for contamination 20 00:01:09,269 --> 00:01:12,355 knowledge, and then bring the sample return capsule 21 00:01:12,589 --> 00:01:16,793 to a temporary cleanroom at the Utah Test and Training Range. 22 00:01:16,893 --> 00:01:18,528 There, we will actually take off the heat 23 00:01:18,528 --> 00:01:21,030 shield and backshell and some other components for safety. 24 00:01:21,030 --> 00:01:23,666 And inside of that is what we call a sample canister. 25 00:01:23,817 --> 00:01:25,885 Sample return capsule is kind of like a nesting doll, 26 00:01:25,885 --> 00:01:27,570 we have these multiple layers of protection. 27 00:01:28,638 --> 00:01:30,807 And then that sample canister 28 00:01:30,807 --> 00:01:34,461 will have a nitrogen flow put on it, what we call a nitrogen purge. 29 00:01:34,727 --> 00:01:37,464 And with that nitrogen purge, to protect the sample, to keep 30 00:01:37,464 --> 00:01:40,550 any incursion of terrestrial atmosphere coming into that canister, 31 00:01:40,550 --> 00:01:43,853 it will be flown from Utah here to Houston, Texas. 32 00:01:44,304 --> 00:01:48,808 The Astromaterials curators at NASA Johnson are the best in the world. 33 00:01:48,842 --> 00:01:51,678 They are fantastic at preserving material. 34 00:01:51,895 --> 00:01:55,982 The samples will be in a special custom- built cleanroom. 35 00:01:56,099 --> 00:02:00,587 The samples themselves will be inside of a of a nitrogen filled glovebox, and 36 00:02:00,587 --> 00:02:04,307 then inside of that, they'll be stored in separate containers for allocation. 37 00:02:04,607 --> 00:02:08,011 The first samples will come out for the science team to 38 00:02:08,578 --> 00:02:12,232 describe what we've seen and produce a catalog within six months 39 00:02:12,232 --> 00:02:15,118 so that researchers around the world can write their own proposals 40 00:02:15,351 --> 00:02:16,169 to request sample. 41 00:02:18,471 --> 00:02:19,139 Oh, I am going 42 00:02:19,139 --> 00:02:22,342 to be so excited to see that sample 43 00:02:22,342 --> 00:02:26,462 and see how much we actually brought back from asteroid Bennu. 44 00:02:26,479 --> 00:02:30,049 It's been a really exciting journey from launch 45 00:02:30,049 --> 00:02:31,501 back to sample return. 46 00:02:31,501 --> 00:02:35,638 That's a seven year journey, seven year process, and at that time 47 00:02:35,939 --> 00:02:39,175 I will have been on the mission for about seven years. 48 00:02:39,475 --> 00:02:42,829 And so it's going to be a wonderful culmination 49 00:02:42,829 --> 00:02:45,348 to this adventure of OSIRIS-REx. 50 00:02:45,949 --> 00:02:49,619 I joined OSIRIS-REx and became part of the mission about three years ago. 51 00:02:49,802 --> 00:02:53,006 It's been really incredible for me because I watched this 52 00:02:53,006 --> 00:02:56,176 mission launch on my cell phone when I was a postdoc. 53 00:02:56,192 --> 00:02:59,262 I heard about it get selected before I applied for my Ph.D. 54 00:02:59,312 --> 00:03:01,281 program, and I remember thinking like, oh, 55 00:03:01,281 --> 00:03:03,199 you know, 12 years it's going to come back. 56 00:03:03,199 --> 00:03:04,367 I wonder where I'll be? 57 00:03:04,367 --> 00:03:07,337 And it's so amazing to be here and be part of it, playing 58 00:03:07,337 --> 00:03:11,941 what feels like to me a very important role in it is really incredible. 59 00:03:13,443 --> 00:03:14,244 I've been waiting 60 00:03:14,244 --> 00:03:17,030 since 2004 for an asteroid sample return mission. 61 00:03:17,447 --> 00:03:21,050 It's been the majority of my career getting ready for sample return. 62 00:03:21,301 --> 00:03:23,820 In some ways, a blink of an eye since launch happened. 63 00:03:23,987 --> 00:03:27,390 In other ways, it's been a very long time waiting for this 64 00:03:27,557 --> 00:03:29,008 precious sample to come back. 65 00:03:29,008 --> 00:03:34,347 It's going to be an emotional, joyous, gut-wrenching event all at the same time. 66 00:03:34,697 --> 00:03:36,499 I can't wait. 67 00:03:36,499 --> 00:03:39,552 [Music] 68 00:03:39,552 --> 00:03:46,509 [Music fades]
