1 00:00:07,607 --> 00:00:10,110 (music throughout) NASA White Sands is a remote test 2 00:00:10,110 --> 00:00:15,281 facility that the agency uses for some of the more dangerous testing 3 00:00:15,782 --> 00:00:18,084 that is needed to support the NASA missions. 4 00:00:19,085 --> 00:00:21,988 The size of the guns, the biggest gun we have 5 00:00:21,988 --> 00:00:25,458 is about 225 feet 6 00:00:25,825 --> 00:00:29,562 and the building itself is only about 200 feet long. 7 00:00:30,196 --> 00:00:33,433 So part of the gun does actually stick out of the building. 8 00:00:34,067 --> 00:00:38,772 There is a very, very large project underway right now that started 9 00:00:38,772 --> 00:00:42,742 not too long ago with the landing of the Perseverance Rover on Mars. 10 00:00:43,143 --> 00:00:46,679 I am a systems engineer for the capture containment and return system. 11 00:00:46,713 --> 00:00:50,050 This system is the NASA payload which is basically responsible 12 00:00:50,050 --> 00:00:52,519 to bring the samples, the Mars samples back to Earth. 13 00:00:53,486 --> 00:00:57,624 When I'm standing in is actually called a hypervelocity test facility. 14 00:00:57,657 --> 00:01:01,861 It's where we shoot little projectiles at objects, basically 15 00:01:01,861 --> 00:01:05,131 as fast as we can achieve on on earth. 16 00:01:05,965 --> 00:01:08,868 In our case, we are testing to see what will happen 17 00:01:09,169 --> 00:01:12,072 to our designs if they were to be impacted 18 00:01:12,072 --> 00:01:14,908 by a micrometeoroid on the trip to or from Mars. 19 00:01:15,742 --> 00:01:19,813 The goal here is to see how well those materials withstand 20 00:01:19,813 --> 00:01:23,850 those impacts, to make sure that we don't lose containment of our sample. 21 00:01:23,850 --> 00:01:30,290 Hypervelocity guns work in two sections, which are a two stage light gas gun. 22 00:01:30,290 --> 00:01:34,861 We pressurized hydrogen in the first section in the middle of the gun. 23 00:01:34,861 --> 00:01:35,795 There's a barrel. 24 00:01:35,795 --> 00:01:37,931 That's where the projectile is held. 25 00:01:38,498 --> 00:01:40,934 The pressures that are generated from these guns 26 00:01:40,934 --> 00:01:45,271 can actually level the building, and that pressure is suddenly released 27 00:01:45,271 --> 00:01:48,842 where the projectile is, where the barrel in the middle of the gun is. 28 00:01:49,342 --> 00:01:52,178 And then from that point on, there's 29 00:01:52,178 --> 00:01:55,548 a simulated vacuum which simulates space, 30 00:01:57,183 --> 00:02:00,787 and then it is impacted where the target is. 31 00:02:02,188 --> 00:02:03,556 It's all about the timing. 32 00:02:03,556 --> 00:02:08,595 You're dealing with about 500 microseconds, for the timing of the event. 33 00:02:08,828 --> 00:02:13,032 So unlike a traditional firearm, a lot goes into preparing these guns 34 00:02:13,032 --> 00:02:18,471 for a shot set up takes anywhere from an hour to a full day. 35 00:02:18,638 --> 00:02:21,141 Gunpowder is prepared and loaded by hand. 36 00:02:22,275 --> 00:02:25,912 We're able to remotely operate the guns via 37 00:02:25,912 --> 00:02:27,347 the bunker 38 00:02:32,652 --> 00:02:34,154 on the count of three, 39 00:02:34,154 --> 00:02:41,427 three, two, one. 40 00:02:41,427 --> 00:02:45,832 It's equal to 25 times faster than a 44 mag. 41 00:02:45,999 --> 00:02:50,670 The velocities are also like flying from New York to San Francisco 42 00:02:50,670 --> 00:02:53,540 in 5 minutes. 43 00:02:56,709 --> 00:02:59,012 One of the interesting things that we learn 44 00:02:59,012 --> 00:03:03,750 is that a massive piece of metal does not offer the same level of protection 45 00:03:03,783 --> 00:03:07,387 of really thin pieces of metal, but stack all together. 46 00:03:07,520 --> 00:03:11,524 What we are doing is we have very light layers of material and those layers 47 00:03:11,524 --> 00:03:14,727 they function to progress, fully break the particles 48 00:03:14,827 --> 00:03:18,798 until the very last layer that receives all the energy from the hit. 49 00:03:19,065 --> 00:03:20,133 And it stops right there. 50 00:03:21,901 --> 00:03:23,870 If it wasn't for this study, 51 00:03:23,870 --> 00:03:29,008 we would be sending up rockets and satellites and 52 00:03:29,642 --> 00:03:33,012 pieces of the space station, not knowing whether they were going 53 00:03:33,012 --> 00:03:36,416 to protect the astronauts or the equipment we send up. 54 00:03:36,583 --> 00:03:40,153 It's a really neat thing to see when you test something 55 00:03:40,153 --> 00:03:44,090 and have it correlate very well back to your your simulations. 56 00:03:44,123 --> 00:03:48,461 I am super excited to be working this mission to bring back samples from Mars. 57 00:03:48,494 --> 00:03:50,163 It is something that has 58 00:03:50,163 --> 00:03:53,900 never been done before and we are learning so much from this, 59 00:03:53,967 --> 00:03:58,171 especially because this Mars is a planet that we had fascinations for a very, 60 00:03:58,171 --> 00:03:59,072 very long time. 61 00:03:59,072 --> 00:04:01,374 So it is 62 00:04:01,608 --> 00:04:04,844 humbling and a lot a lot of work, right. 63 00:04:04,844 --> 00:04:06,746 Being here testing things. 64 00:04:06,746 --> 00:04:09,749 It's it's amazing.
