WEBVTT 00:00:00.000 --> 00:00:03.280 So this is a piece of old hardware. 00:00:03.280 --> 00:00:07.520 The 6600 psi helium compressor. 00:00:07.520 --> 00:00:13.400 So at the start of the space race, we needed to measure what we call high Reynolds number 00:00:13.400 --> 00:00:18.560 flow, which is the way we normalize the speed 00:00:18.560 --> 00:00:22.480 and the viscosity and the nature of the air around objects. 00:00:22.480 --> 00:00:25.680 And one of the ways you can tweak that 00:00:25.680 --> 00:00:29.560 is by changing the gas you're using. 00:00:29.560 --> 00:00:33.480 And so part of that process, to get really high speed, 00:00:33.480 --> 00:00:37.960 non-reacting gas, was to compress helium. 00:00:37.960 --> 00:00:42.560 And so they built this marvel of compressor technology 00:00:42.560 --> 00:00:49.480 back in the 50s and the 60s. It's now abandoned in place, but it really 00:00:49.480 --> 00:00:57.040 is a marvel of the kind of clever engineering that they were able to do when there was that kind of big push 00:00:57.040 --> 00:01:02.920 to know. What's that noise? Those are F-22s, 1438s. 00:01:02.920 --> 00:01:06.120 Based on the sound, probably an F-22. 00:01:06.120 --> 00:01:09.760 Our neighbors at Langley Air Force Base routinely 00:01:09.760 --> 00:01:11.320 fly overhead every day as an air show. 00:01:17.200 --> 00:01:19.240 Hey, finally, I'm not the biggest tool in the room. 00:01:23.880 --> 00:01:28.000 Yeah, so big doors with crane access 00:01:28.000 --> 00:01:32.560 to be able to pull stuff in and out of these lab spaces. 00:01:32.560 --> 00:01:37.160 These are, I wouldn't say blast proof, but blast resistant. 00:01:37.160 --> 00:01:41.360 So that if there is a mishap within the facility, 00:01:41.360 --> 00:01:46.880 everyone is safe. And we have not had a fatality on center since the 80s. 00:01:46.880 --> 00:01:51.640 This is my lab here. It used to have one of the big blast doors. 00:01:51.640 --> 00:01:56.440 Sometime in the early 2000s, it was converted to office space 00:01:56.480 --> 00:02:01.960 and then converted back to lab space. But the blast door was forever gone. 00:02:01.960 --> 00:02:05.680 So if an explosion happens here, people might. 00:02:05.680 --> 00:02:09.120 We don't do it. Nothing combusting happens in this lab. 00:02:09.120 --> 00:02:13.160 Yet. Maybe today is the day. 00:02:13.160 --> 00:02:21.280 Welcome to the, I think what we're calling the high speed flow diagnostics lab. 00:02:21.280 --> 00:02:24.560 Wow. So this is a vacuum manifold. 00:02:24.560 --> 00:02:29.840 It goes and connects up to all of the piping on the roof of the building that then connects to the vacuum 00:02:29.840 --> 00:02:34.280 spheres outside. And those are pumped down to very low vacuum pressures 00:02:34.280 --> 00:02:36.040 on the scale of millitor. 00:02:38.840 --> 00:02:42.920 Yeah, what is it? I know what that means. But for the people who don't know what that means, 00:02:42.920 --> 00:02:47.720 what is a millitor? A tour. Isn't that like a historical, like a half man, half bull? 00:02:47.720 --> 00:02:50.720 That's a centaur. No, that centaur's horse. 00:02:50.720 --> 00:02:54.400 Minotaur. Minotaur, minotaur. Millitor. 00:02:54.400 --> 00:02:57.680 It's a millitor. Tour is a unit of pressure. 00:02:57.680 --> 00:03:01.480 I don't know what it is in PSI off the top of my head. 00:03:01.480 --> 00:03:08.160 But suffice to say, it's very low. It's not space vacuum, but it's such a low vacuum 00:03:08.160 --> 00:03:12.240 as to be considered vacuum for all intents and purposes. 00:03:12.240 --> 00:03:15.400 So when do we get to use this? We do not get to use this. 00:03:15.400 --> 00:03:19.560 This is abandoned in place hardware. 00:03:19.560 --> 00:03:22.840 I'm told it will be removed sometime in the 2030s. 00:03:23.480 --> 00:03:26.720 I wish I could give timelines like that for my work. 00:03:26.720 --> 00:03:31.520 Yeah, I'll do it in a decade. I'm going to get this recommissioned, 00:03:31.520 --> 00:03:34.600 and so I can slap experiments on the end of it 00:03:34.600 --> 00:03:39.200 and use the great equipment we have to do more science. 00:03:39.200 --> 00:03:42.400 This is the only part I'm not afraid of touching. This is the part that seems normal to me. 00:03:42.400 --> 00:03:46.960 This terrifies me. This is all pretty robust. 00:03:46.960 --> 00:03:50.200 We dropped the power supply for these the other week. 00:03:50.200 --> 00:03:54.680 It's still running. More like, this is a dent, but it still runs. 00:03:54.680 --> 00:04:00.000 So this is a lab space. We have optical tables where we do kind of the core science. 00:04:00.000 --> 00:04:07.080 There's never enough optical table space. Projects will expand to fill the optical table provided. 00:04:07.080 --> 00:04:14.560 Always hunting for more optical tables. Then we've got a space where we can kind of resin 3D print, 00:04:14.560 --> 00:04:18.680 tanker, design a thing, print it off, 00:04:18.840 --> 00:04:22.440 put it on the bench top all within an afternoon, 00:04:22.440 --> 00:04:26.600 which is a really great way for us to iterate on our ideas, 00:04:26.600 --> 00:04:32.600 little kind of early phase things that we're seeing if there's a there, there, and do it quick, efficiently, 00:04:32.600 --> 00:04:37.080 and precisely, which is what we'll be doing with the fan today. 00:04:37.080 --> 00:04:41.560 This is 400 nanometer UV light. It will give you a sunburn. 00:04:41.560 --> 00:04:46.160 Don't look directly at it. I mean, if you really want a tan, there you go. 00:04:46.160 --> 00:04:49.200 I want a circulated sunburn back the fan off a little bit. 00:04:49.200 --> 00:04:50.680 These are the UV lights. 00:04:52.680 --> 00:04:57.080 We'll turn off the overheads to to get a better view. 00:05:01.080 --> 00:05:04.680 Are there reflections of the UV light, something to worry about? Not really. 00:05:04.680 --> 00:05:10.240 These two light, these two lights here are 400 nanometer UV lights, 00:05:10.240 --> 00:05:14.080 which is a wavelength that is actually harmful for humans. 00:05:14.080 --> 00:05:19.080 So we don't want to get too far in front of it. What it's doing is that it's allowing us to see this glow in the dark string. 00:05:19.080 --> 00:05:23.080 We're recording that glow in the dark string with this 1000 FPS camera. 00:05:23.080 --> 00:05:28.080 It's 4K 1000. 4K, how much data is that? 00:05:28.080 --> 00:05:32.080 They spec it at 11 and change gigabits per second. 00:05:32.080 --> 00:05:40.080 11 gigabits of data per second when you're recording at 4K 11 gigabits? 00:05:41.080 --> 00:05:50.080 11 gigabits? If you recorded like a minute, you're almost at, 00:05:50.080 --> 00:05:54.080 if you recorded like a minute and a half, you're at a terabyte, a terabit. 00:05:54.080 --> 00:06:01.080 I guess it'd be eight minutes to a terabyte. Bits to bytes gives you a little bit of, you know, that eight times space to get more, 00:06:01.080 --> 00:06:05.080 but there's a terabyte in there on the drive. 00:06:05.080 --> 00:06:11.080 So recording at our current settings, we can get 11 seconds of data into the terabyte SSD. 00:06:11.080 --> 00:06:16.080 We're going to go dark now? Yep. You can see the side that was pointed at the light when I was testing it, 00:06:16.080 --> 00:06:23.080 then the side that wasn't. AmEx, your CFD code, is rendering real physics correctly. 00:06:23.080 --> 00:06:28.080 Yeah. He makes this stuff so that they can make this stuff. 00:06:28.080 --> 00:06:32.080 Yeah. It's making stuff all the way up. 00:06:32.080 --> 00:06:34.080 All the way down. 00:06:35.080 --> 00:06:38.080 It's the turtle on which the earth is supported. 00:06:38.080 --> 00:06:43.080 This was originally built to test, to practice landing on the moon. 00:06:43.080 --> 00:06:51.080 So they had a, you can see it in a picture right here, a practice lunar landing module, 00:06:51.080 --> 00:06:56.080 and they would suspend it from the gantry at 16G, 00:06:56.080 --> 00:07:00.080 and they would practice maneuvering it with jets to land. 00:07:00.080 --> 00:07:04.080 There was a second version of this vehicle that had a big jet engine strap to the bottom, 00:07:04.080 --> 00:07:08.080 and they tested that out at Edwards Air Force Base, 00:07:08.080 --> 00:07:11.080 what is now the NASA Armstrong Flight Research Center. 00:07:11.080 --> 00:07:16.080 That one, there were three of them, and all but one crashed, 00:07:16.080 --> 00:07:22.080 because it turns out when you're gimbling on top of a giant jet engine, it's not very safe. 00:07:22.080 --> 00:07:27.080 So a lot of ejections out of that vehicle. This was a much safer, much more controlled way to practice. 00:07:27.080 --> 00:07:31.080 You got good here before they put you on the jet engine one. 00:07:31.080 --> 00:07:37.080 What we use it for now is very scientifically dropping things. 00:07:37.080 --> 00:07:41.080 So now it is the... Can you hear that Linus? 00:07:41.080 --> 00:07:48.080 The Impact Dynamics Research Facility, we fictionally call it the gantry still, 00:07:48.080 --> 00:07:59.080 and we will throw small aircraft, space reentry capsules to test the physics of how a crash happens, 00:07:59.080 --> 00:08:05.080 and also to verify that when we do crash or we land on land or water, 00:08:05.080 --> 00:08:09.080 that the vehicle performs how we expected it to, that it's safe for the astronauts, 00:08:09.080 --> 00:08:12.080 that it's safe for the occupants. We've got... 00:08:12.080 --> 00:08:17.080 When we're doing a test out here, they've got it all pulled up and rigged up and hanging, 00:08:17.080 --> 00:08:20.080 and it's really cool to see it go and... 00:08:20.080 --> 00:08:25.080 And I'm sure there's a great video of that we can provide you, 00:08:25.080 --> 00:08:30.080 both landing on ground and then we've got a pool that we built at the other end. 00:08:30.080 --> 00:08:33.080 You've got a pool? We've got a pool. NASA's got a pool? 00:08:33.080 --> 00:08:38.080 I wouldn't go swimming in that pool. Why not? We'd walk down to the pool. 00:08:38.080 --> 00:08:41.080 And that's to study water landings. 00:08:41.080 --> 00:08:45.080 And so when we tested the space shuttle, not the space shuttle, 00:08:45.080 --> 00:08:51.080 the SpaceX capsule recently, we swung from the top of the gantry, 00:08:51.080 --> 00:08:55.080 lofted it, and then tested the splashdown. 00:08:55.080 --> 00:08:58.080 Have they ever missed? No. 00:08:58.080 --> 00:09:01.080 Okay. The people here are super good at what they do. 00:09:01.080 --> 00:09:07.080 Yeah. And when they throw something off the gantry, they know exactly where it's going to go. 00:09:07.080 --> 00:09:16.080 I would expect nothing less from NASA. Everything we do here, we're pushing the limits to understand how to safely crash, 00:09:16.080 --> 00:09:19.080 but when we're studying it, safety is the number one priority. 00:09:19.080 --> 00:09:24.080 Absolutely. The test is broadly going to do, and it's the details that we're studying. 00:09:24.080 --> 00:09:27.080 Cool. So we don't want to hurt anyone. We don't want to break anything. 00:09:27.080 --> 00:09:31.080 This is a unique national asset, a historic landmark. 00:09:31.080 --> 00:09:34.080 So we want to make sure we don't break it. 00:09:34.080 --> 00:09:37.080 Yeah. In the pursuit of breaking other things. 00:09:37.080 --> 00:09:41.080 Yeah. Let us know in the comments below what you want us to drop here. 00:09:41.080 --> 00:09:45.080 Okay. No 5090s will be harmed. 00:09:45.080 --> 00:09:50.080 Unless you guys put it in the comments below. We're at the pool that we were just talking about, but can you tell me what these like 00:09:50.080 --> 00:09:56.080 sigils are at the back? So those are photogrammetry registration points. 00:09:56.080 --> 00:10:01.080 So when we point a bunch of cameras at the test article that we're flinging from the gantry 00:10:01.080 --> 00:10:06.080 into the water, we know where the cameras are looking at in physical space relative to 00:10:06.080 --> 00:10:10.080 what's seen on their image sensor. So each one is a slightly different pattern. 00:10:10.080 --> 00:10:16.080 The software picks out where they are and does camera registration to know spatially 00:10:16.080 --> 00:10:19.080 what the cameras are seeing. Okay. 00:10:19.080 --> 00:10:22.080 How deep is this pool? I don't know. 00:10:22.080 --> 00:10:29.080 It's definitely deeper than would be comfortable to swim in. 00:10:29.080 --> 00:10:32.080 It's definitely dozens of feet deep. 00:10:32.080 --> 00:10:36.080 Okay. But I don't know the exact number. 00:10:36.080 --> 00:10:39.080 And then over there, you said that this is where current test articles are? 00:10:39.080 --> 00:10:43.080 Some current and old test articles are built up in there. 00:10:43.080 --> 00:10:48.080 Just so we have a little bit of shade for our technicians working in there. 00:10:48.080 --> 00:10:52.080 It gets brutally hot out here. No kidding. 00:10:52.080 --> 00:10:55.080 But it's a fun place to be. 00:10:55.080 --> 00:10:58.080 I also see that gridded wall has numbers and markings on it. Same deal? 00:10:58.080 --> 00:11:01.080 Same deal. Yep. Know where the cameras are. 00:11:01.080 --> 00:11:08.080 So that's the old way to do it. You have a grid and you match the grid in pixel space to physical space. 00:11:08.080 --> 00:11:13.080 The more modern computer vision any way to do it is with those targeting dots. 00:11:13.080 --> 00:11:16.080 It's just different generations of the same technology. 00:11:16.080 --> 00:11:19.080 I think that kind of represents this place. Yes. 00:11:19.080 --> 00:11:25.080 Different generations of the same technology, whether that's like 50, 70 year old wind tunnels. 00:11:25.080 --> 00:11:30.080 Yep. To the brand new vertical wind tunnel that you're putting up with the new. 00:11:30.080 --> 00:11:35.080 All of the things we learn from the older facilities go into what we build. 00:11:35.080 --> 00:11:41.080 We spend a lot of time and care in sorting our existing capabilities, our older wind tunnels, 00:11:41.080 --> 00:11:45.080 upgrading them with newer measurement equipment, newer control equipment, 00:11:45.080 --> 00:11:50.080 so that they continue to be useful in doing good science for decades to come. 00:11:50.080 --> 00:11:54.080 I'm Gary Qualls. I've been here at NASA Langley since the mid-80s. 00:11:54.080 --> 00:11:58.080 Oh wow. And it's a lot of really cool work here. 00:11:58.080 --> 00:12:04.080 You guys are in the Lark Works Makerspace. This is a space where anybody on center, basically anybody here with a badge 00:12:04.080 --> 00:12:09.080 can come in and try to do new things and learn new skills or build prototypes 00:12:09.080 --> 00:12:12.080 or just collaborate with other people. 00:12:12.080 --> 00:12:17.080 And in government parlance, you don't need a charge code. 00:12:17.080 --> 00:12:25.080 You can just come in here and use this stuff. I think we all know prototyping tools have gotten a lot cheaper and a lot more accessible. 00:12:25.080 --> 00:12:30.080 So it's possible to keep a place like this going on a pretty reasonable budget 00:12:30.080 --> 00:12:35.080 and allow the researchers here to just get a lot of work done in a short period of time 00:12:35.080 --> 00:12:39.080 and to do things at scale. I'm going to give you guys a quick tour. 00:12:39.080 --> 00:12:42.080 We're very 3D printer heavy for a Makerspace. 00:12:42.080 --> 00:12:45.080 We've got about 63D printers active right now. 00:12:45.080 --> 00:12:51.080 That's a normal number for us. A lot of the printers that we have are these smaller kind of desktop models. 00:12:51.080 --> 00:12:54.080 We print 95% PLA in here. 00:12:54.080 --> 00:12:57.080 It's just very beginner friendly, very easy to get going. 00:12:57.080 --> 00:13:00.080 We do have some of these bigger 3D printers. 00:13:00.080 --> 00:13:07.080 This is a Gigabot, US made printer. These have a print volume that's 23.2 by 30 by 36 inches. 00:13:07.080 --> 00:13:11.080 They have a decent demand in here for full scale parts for all kinds of different reasons. 00:13:11.080 --> 00:13:14.080 We have more exotic printers over here. 00:13:14.080 --> 00:13:18.080 What is something that you've printed on this? Do you have any examples? 00:13:18.080 --> 00:13:21.080 Yeah, I can show you guys some examples in a couple of minutes. 00:13:21.080 --> 00:13:26.080 We've got some full scale launch hardware. We've got full scale Mars rover wheels. 00:13:26.080 --> 00:13:33.080 You could show folks that are great for outreach and really explaining the different kinds of jobs that NASA does. 00:13:33.080 --> 00:13:41.080 This is a part for a wind tunnel to help seal something that's moving that's very complicated. 00:13:41.080 --> 00:13:47.080 They all get a little bit more difficult to explain, but we do have some things that are easy. 00:13:47.080 --> 00:13:50.080 The dudes at the lab are going to be so jealous. 00:13:50.080 --> 00:13:53.080 Creator Warehouse is going to be so jealous of this, I'm sure. 00:13:53.080 --> 00:13:57.080 In addition to the 3D printing that's available here, which is pretty generic. 00:13:57.080 --> 00:14:04.080 We do have special purpose 3D printers. These can inlay continuous carbon fiber Kevlar fiberglass into the parts. 00:14:04.080 --> 00:14:08.080 We have some larger printers over here that do multicolor and multi-material. 00:14:08.080 --> 00:14:12.080 These cabinets down here are full of electronics. 00:14:12.080 --> 00:14:20.080 So we have basically sensors here that people can use to build prototype machinery, mechatronic things. 00:14:20.080 --> 00:14:29.080 So you could do soil moisture or relative humidity, light break sensors, accelerometers, gyros, all kinds of things like that. 00:14:29.080 --> 00:14:40.080 Magnetic fields, right? We've got motors down here, servos, stepper motors, solenoids, magnetic grabbers to pick things up. 00:14:40.080 --> 00:14:43.080 All kinds of microcontrollers, LEDs. 00:14:43.080 --> 00:14:46.080 Things get more sophisticated as you go down the row here. 00:14:46.080 --> 00:14:55.080 So we've got software to find radios, autopilots for drones, things to reverse engineer and troubleshoot, all kinds of different data networks. 00:14:55.080 --> 00:14:58.080 So it's a pretty extensive space. 00:14:58.080 --> 00:15:04.080 The whole idea is if somebody has an idea, they should be able to just come in here, start building it right away, 00:15:04.080 --> 00:15:09.080 and not have to wait two weeks for procurement to order all the parts and get approvals. 00:15:10.080 --> 00:15:17.080 And, you know, have something working the same day that you could show people or just test your idea to see if it's going to work. 00:15:17.080 --> 00:15:21.080 And that's the whole plan. Everything in here is on wheels. 00:15:21.080 --> 00:15:24.080 We can reconfigure the room to support different kinds of training. 00:15:24.080 --> 00:15:29.080 Or sometimes I'll have a group that's just hosted here or a grad student in the corner for a few weeks doing work. 00:15:29.080 --> 00:15:36.080 We have these electronics workstations. We've got a pretty decent oscilloscope, nice benchtop power supplies, soldering station, 00:15:36.080 --> 00:15:39.080 really cool microscope where you can see in stereo. 00:15:39.080 --> 00:15:42.080 That's kind of cool. We have some higher end stuff. 00:15:42.080 --> 00:15:46.080 So we've got two of these universal robots. 00:15:46.080 --> 00:15:56.080 You are 10 arms. We make these available to researchers to support different kinds of internal R&D projects or, you know, anything just to learn how to use robot arms, right? 00:15:56.080 --> 00:16:05.080 So one of the things that, one of the themes we really stress here is this is a place where you can come and learn to do the things that you really only learn by doing. 00:16:05.080 --> 00:16:14.080 Whether it's the electronics or 3D printing or using robot arms, you know, people can tell you how to do it or you can read about how to do it or you can watch how to do it on YouTube. 00:16:14.080 --> 00:16:21.080 But until you really do it or try to do it and it doesn't work for like 45 minutes and you're like, I thought this is exactly how it's going to work. 00:16:21.080 --> 00:16:29.080 But finally you do figure out, oh, it's wired this way or I have to do this and reset it and then I can load the code. 00:16:29.080 --> 00:16:34.080 You know, whatever that process is, when you really do get it working, you really have learned something. 00:16:34.080 --> 00:16:37.080 And then you can make those things work. 00:16:37.080 --> 00:16:45.080 And the importance of that for NASA being able to do those complex things is, you know, those are the jobs we're called to do. 00:16:45.080 --> 00:16:50.080 If you look back at this wall, these are vehicles that we can loan or give to different research teams. 00:16:50.080 --> 00:16:54.080 We've got a whole bunch of different kinds of rovers. There's a little submarine up there. 00:16:54.080 --> 00:16:59.080 We're very drone heavy because NASA Langley is an aeronautics research center. 00:16:59.080 --> 00:17:10.080 But, you know, the people, you know, when you're putting a rover on Mars, right, you've got software, you've got all the wiring, you've got all the components. 00:17:10.080 --> 00:17:20.080 And all of that has to work together. So you really have to know how to troubleshoot those things, how to integrate them and really how to design and architect them so that when something's failing, 00:17:20.080 --> 00:17:30.080 you can localize where the failure is and troubleshoot it and solve the problem quickly instead of just starting to change things to see if it starts working again. 00:17:30.080 --> 00:17:33.080 So those are the skills that we look for in people. 00:17:33.080 --> 00:17:37.080 And again, those are the skills you develop by doing things. 00:17:37.080 --> 00:17:46.080 And our young engineers need to have the experiences of doing those things so that they're ready when the big projects come along. 00:17:46.080 --> 00:17:49.080 This area right here, we've got some of the other robots. 00:17:49.080 --> 00:17:53.080 We've got these two-spot robots that were being used on this Fit to Fly project. 00:17:53.080 --> 00:17:57.080 This is looking at automated aircraft maintenance and repair. 00:17:57.080 --> 00:18:04.080 You can see some video here from when we partnered with Elroy Air, which is a big cargo drone company out in California. 00:18:04.080 --> 00:18:08.080 And, you know, those cargo drones are big enough to carry their own robotic ground crews. 00:18:08.080 --> 00:18:13.080 We've got other kinds of rovers that we're looking at, different collaborations with the Air Force. 00:18:13.080 --> 00:18:17.080 This is an example of a drone that a graduate student came in and modified. 00:18:17.080 --> 00:18:24.080 So he had to learn how to do CAD. He wanted to do curved arms for the drone instead of these normal straight arms. 00:18:24.080 --> 00:18:29.080 And, you know, he had to learn how to do computer-aided design. 00:18:29.080 --> 00:18:33.080 And he had to learn how to do 3D printing on the gigabots to print these big arms. 00:18:33.080 --> 00:18:37.080 Probably went through 14 prototypes. Then he had to learn how to rewire everything. 00:18:37.080 --> 00:18:41.080 Then he found out that the autopilots don't produce very good altitude estimates. 00:18:41.080 --> 00:18:45.080 He needed to put on a LiDAR to get a really accurate altitude, 00:18:45.080 --> 00:18:49.080 because this was flying over an array of microphones to measure how much sound it made. 00:18:49.080 --> 00:18:54.080 So he got a LiDAR out of the drawer. He got an Arduino that a lot of your viewers will recognize. 00:18:54.080 --> 00:18:59.080 A microSD card for the data. Bluetooth chip so you can see the data streaming on his phone. 00:18:59.080 --> 00:19:04.080 And we said, well, you know, once the copter is armed, you can't approach it to make sure it's working. 00:19:04.080 --> 00:19:09.080 And the last thing you want to do is have eight people out helping you on a flight test for an hour. 00:19:09.080 --> 00:19:12.080 And then the data card's empty, right? 00:19:12.080 --> 00:19:17.080 And then he designed a box, got him to write off and on it, right? 00:19:17.080 --> 00:19:22.080 This is the definition of a rabbit hole, right? Yeah, but he was able to get this done in about four months, right? 00:19:22.080 --> 00:19:25.080 Beginning to end, picked up all these skills. 00:19:25.080 --> 00:19:31.080 He's working on his PhD in acoustics, so he knows a lot, but nothing about this, right? 00:19:31.080 --> 00:19:37.080 So this is a place where he could come in and, you know, with a little bit of help, learn to do all those things himself. 00:19:37.080 --> 00:19:40.080 You know, that's a nice demo story for kids. 00:19:40.080 --> 00:19:47.080 You know, is that one thing I didn't learn until we really 3D printed these and assembled them. 00:19:47.080 --> 00:19:50.080 Of course, we did it in plastic. The real ones are in metal. 00:19:50.080 --> 00:19:57.080 Is that, you know, this hub is mounted here with these spokes, which have this really cool, curvy design. 00:19:57.080 --> 00:20:01.080 These spokes are providing the whole suspension of the rover. 00:20:01.080 --> 00:20:05.080 Everything is rigid, but when something needs to give a little bit going over a rock, 00:20:05.080 --> 00:20:10.080 it's the flexing of these spokes. There aren't any shock absorbers or springs somewhere. 00:20:10.080 --> 00:20:13.080 Because you wouldn't want to have air in your tires. Right. 00:20:13.080 --> 00:20:16.080 Because the temperature variation. Yeah. 00:20:16.080 --> 00:20:19.080 Yeah. That's... Yeah. 00:20:19.080 --> 00:20:23.080 I mean, so... This is a Launch Abort 1 rocket. 00:20:23.080 --> 00:20:27.080 So they had to test the Launch Abort rockets on the launch pad to the real launch. 00:20:27.080 --> 00:20:31.080 And this area here would have been the top of the rocket. 00:20:31.080 --> 00:20:38.080 And this is the mount point. These six points are where the actual space capsule would mount on top of the rocket. 00:20:38.080 --> 00:20:46.080 So when you look through that little hole, you're looking at the top of this giant bracket. 00:20:46.080 --> 00:20:49.080 That was machined out of an exotic aluminum alloy. 00:20:49.080 --> 00:20:54.080 And there's an explosive bolt that would go in here that would help hold the space capsule on. 00:20:54.080 --> 00:21:00.080 So the bottom heat shield of the space capsule is coming across like this and kind of curves up here. 00:21:00.080 --> 00:21:03.080 There's an explosive bolt in there that holds it. 00:21:03.080 --> 00:21:09.080 And a spring-loaded pin that can push the capsule away from the rocket if everything goes wrong and they're just drifting in space. 00:21:09.080 --> 00:21:13.080 So the group that designed this was here at Langley. 00:21:13.080 --> 00:21:20.080 And their computer analysis said that there's enough room in this hole for somebody to get their ARM in with a wrench. 00:21:20.080 --> 00:21:24.080 And retract this pin and lock it out for launch. 00:21:24.080 --> 00:21:27.080 And the computer said, plenty of room. 00:21:27.080 --> 00:21:32.080 But they didn't want to have the whole launch schedule and everything depending on that analysis. 00:21:32.080 --> 00:21:36.080 So they 3D printed this full-scale version of it so they could try it themselves. 00:21:36.080 --> 00:21:39.080 And it got in there with a wrench and proved they could do it. 00:21:39.080 --> 00:21:45.080 And then while they're doing it, they're like, hey, we could take pictures of us doing it and put it in the documentation. 00:21:45.080 --> 00:21:50.080 Because the people doing that in the vehicle assembly building actually don't know what's down in that hole. 00:21:50.080 --> 00:21:57.080 They've never seen any of this. And then they decided to reprint the parts in color so they could label them in the documentation. 00:21:57.080 --> 00:22:01.080 Because they weren't Photoshop guys. They were designers, right? 00:22:01.080 --> 00:22:09.080 They 3D printed them in different colors and made really nice documentation so the people on the launchpad know exactly what they're doing when they're reaching into these holes. 00:22:09.080 --> 00:22:17.080 And everything could go like clockwork. So that's just another example of why full-scale 3D printing is found at a home in here. 00:22:17.080 --> 00:22:22.080 And we'll try out a machine and then if it gets popular, that's when we start building out. 00:22:22.080 --> 00:22:25.080 That's why we've got multiple of big machines, right? 00:22:25.080 --> 00:22:32.080 Multiple resin machines. If you guys want to take a look in here where we keep things that need a little bit more training for people to use. 00:22:32.080 --> 00:22:35.080 We've got a CO2 laser in the corner there. 00:22:35.080 --> 00:22:41.080 The reason it's in here is if you put PVC plastic, a really common plastic in that laser, it's going to make mustard gas. 00:22:41.080 --> 00:22:46.080 Very frowned upon in the workplace. So there's special training. 00:22:46.080 --> 00:22:51.080 Don't put mystery plastics in the laser cutter. The main thing that happens in here are the resin printers. 00:22:51.080 --> 00:22:58.080 These are a little less beginner friendly. They can print at higher resolution than the other 3D printers you guys saw. 00:22:58.080 --> 00:23:03.080 We have over 13 different kinds of resin. So they can print things with all kinds of different material properties. 00:23:03.080 --> 00:23:06.080 They could be stretchy or soft, super rigid. 00:23:06.080 --> 00:23:11.080 Have a super nice surface finish or whatever they need. 00:23:11.080 --> 00:23:14.080 High temperature, lost wax casting. 00:23:14.080 --> 00:23:17.080 We had a project that was, you know, they're Plan A. 00:23:17.080 --> 00:23:20.080 They were going to print these propeller blades in titanium. 00:23:20.080 --> 00:23:23.080 I don't know if you guys have seen much 3D printed metal. 00:23:23.080 --> 00:23:29.080 This is printed across the street in the next building. So these are a little heavy, right? 00:23:29.080 --> 00:23:34.080 If that breaks out of the hub while it's spinning at 6,000 RPM, 00:23:34.080 --> 00:23:38.080 it's going to go through like two Labs and find an interns rib cage, right? 00:23:38.080 --> 00:23:43.080 So it's nobody wants. So they're like, hey, let's go to the makerspace. 00:23:43.080 --> 00:23:46.080 See what, if we can print a propeller blade, that would work, right? 00:23:46.080 --> 00:23:51.080 So this is the one they ended up with. That's printed in a really rigid resin. 00:23:51.080 --> 00:23:56.080 And that's the surface finish out of the printer. And those worked fine at 6,000 RPM and carried all the loads. 00:23:56.080 --> 00:23:59.080 That's the finish out of the printer. Yeah. Yeah, it's crazy. 00:23:59.080 --> 00:24:03.080 After it's washed. After it's washed, right. But it hasn't been sanded or, yeah. 00:24:03.080 --> 00:24:08.080 That's crazy. Yeah. So those are the kind of things people, you know, come in here. 00:24:08.080 --> 00:24:11.080 There's a, you know, slide because we're NASA. 00:24:11.080 --> 00:24:14.080 We have a lot of slides. But, you know, these two guys are pretty cool. 00:24:14.080 --> 00:24:18.080 They're a couple of buildings over. They have their own wind tunnel. 00:24:18.080 --> 00:24:21.080 They're in a micro tent building that we're just in. 00:24:21.080 --> 00:24:27.080 Yeah. The building you guys came from. And they found out, you know, they can print models in this clear resin. 00:24:27.080 --> 00:24:31.080 And not only can they measure the shock waves off of this really well, 00:24:31.080 --> 00:24:36.080 but they can do the thermography to look at heating on the surface with this resin. 00:24:36.080 --> 00:24:41.080 So now they can find out, oh, we've got tunnel time on Friday. 00:24:41.080 --> 00:24:44.080 Come over here with a design, print it overnight, 00:24:44.080 --> 00:24:47.080 and have it in the wind tunnel the next afternoon, ready to go. 00:24:47.080 --> 00:24:51.080 So that's really opened up the kind of research things they can investigate. 00:24:51.080 --> 00:24:55.080 And those are the, you know, we're just bringing people in more and more. 00:24:55.080 --> 00:25:01.080 And, you know, it's, that's what we're here for is allow researchers to really come in here, 00:25:01.080 --> 00:25:04.080 do things quickly, and get back to work. 00:25:04.080 --> 00:25:10.080 We've got numerous stories where people were getting ready to deploy on a test out west somewhere. 00:25:10.080 --> 00:25:16.080 They needed 132 adapters to attach these microphones to these plates out in the field. 00:25:16.080 --> 00:25:21.080 And they're able to just colonize, you know, 20-some printers and just print all weekend 00:25:21.080 --> 00:25:24.080 and have all the parts they needed to head out the door. 00:25:24.080 --> 00:25:27.080 So. Awesome. Cool. 00:25:27.080 --> 00:25:30.080 Yeah, thank you so much for the tour. That was, obviously, a flawless note. 00:25:30.080 --> 00:25:33.080 Whoa. We made a couple of astronauts for you guys. 00:25:33.080 --> 00:25:36.080 Thank you so much. So you can take those home. These are amazing. 00:25:36.080 --> 00:25:40.080 Watch over you, I guess. Maybe cheer you on. 00:25:40.080 --> 00:25:43.080 Thank you so much. No problem. 00:25:43.080 --> 00:25:47.080 These are awesome. I love the little. I want you guys to leave here empty-handed. 00:25:47.080 --> 00:25:53.080 I feel like, this is so cool. 00:25:53.080 --> 00:25:57.080 Thank you so much. Yeah, no problem. NASA internships are open year-round. 00:25:57.080 --> 00:26:00.080 All year. Yeah. You can sign up. 00:26:00.080 --> 00:26:03.080 Paid internships? Let us know. Yeah, they have paid internships. 00:26:03.080 --> 00:26:06.080 That's it. All right, see you later, Linus. I'm done. 00:26:06.080 --> 00:26:07.080 I'm gone.
