Angles especially around some of the remote stuff. A lot of things you guys do work with like Rovers. You talked about spirit just to have a conversation with those things is like we complain about late and senior website was slow or I was playing this game and it was hard because there was. Two hundred milliseconds of latency. There's different kinds of latency out in space. Right? Wouldn't the speed light is not enough. So he can some of the smart and putting it on rovers and other stuff. Some of this ai work that you're doing. It sounds like it might have some lakes Ai I. Hope. So and we think it does too. So Michael, basically the work that. We're doing for your listeners. We have a project that we've been investigating now. So let's fast forward the clock rovers nowadays the last one that landed on the planet. I won't say that we shipped because we just shipped one, which we'll talk about called does a couple of weeks. The right we did pandemic shipping and launching of rockets, Rovers, new fad but yes, for pre. That pre pandemic in two thousand, twelve, we ship the the Mars Science Laboratory or the Curiosity Rover, and that one is about. So spirited opportunity just the size them ver- you know your listeners it's about the size if you have kids of one of those cars that you push maybe or something like that or maybe like a power wheel big wheel type of thing that size. Of Spirit and opportunity the MSL rover is about the size of a small car like Volkswagen bug and if you came to jpl and it was open to have these some day and things like that, you could walk into our building agency a full scale model of to really get the feel of it but that's the size rover over that we're talking about now that's. Sort of the modern class at them and so twenty, twenty s the perseverance, the launched it's the same size. So we've got MSL still operating spirit and opportunity arts anymore because they were solar-powered MSL is powered basically by nuclear fission uses an rtd power source and things like that. So it doesn't have to worry about solar panels so it can go for quite a while and. Has Been. So it's a great test basically as long as it mechanically is still functioning right? Absolutely and so challenges with mechanical functioning are like, Hey, we learned a lot about the wheels for a car sized thing as we drove over walks in it toward the wheels up, you know and things, and so we did we learned a lot about them if you look at one. Quick Update and twenty twenty as the wheels have little homer simpson speed holes are not speed old but holes to prevent having just track and tread that dies catching on everything and that's just one thing we learned amongst other things. We've got smart engineers JPL. MSL's agree platform to test stuff out on. However let's talk about AIML L. I'm going to dispel some missing rumor so. MSL and space assets and others they all need right we gotta do computing we need a processor and A. And things like that they are running off of an old the what is that the latest? GP probably like a Invidia like twenty eighty something like that. Yeah. Everybody thinks that and I know you're being facetious and I liked the snark it's awesome. But yes, no, and that's the challenge. Everybody thinks that and it's not it's running off of a rats fifty, which is a be a h that's as bad as powerful as a POWERPC chip and process or in so and why real quick y right when we crash something in the government, we've got a congressional inquiry that we have to respond to. This virtual companies do it and we love the commercial companies where partner with them. Now, they don't right they I mean not to say that it doesn't ruin their value stream or their reputation or things like that. But they've got a little bit more flexibility to do testing and stuff like that than we do and so we are risk averse by profile definition, and so because of that, we were only use things that are what we. Call radiation hardened, which means that when it gets up there in space, a space does and cosmic radiation do weird things to your hardware they flip the bids amongst that's the easy stuff they do. They do a lot of other nasty stuff and so you gotta make sure that the hardware works in space and so because of that the technology, the Gartner life cycle for what we could use for that is real behind and so this big. Smart this big. Potentially smart you know and it is smart. They did great things on MSL and they're going to do even greater on twenty twenty is writing off of an old processor. So the I is human in the loop even more. So coupled with the fact that you alluded to, Hey, you know bandwidth latency you think that's an issue the lifetime from Earth to Mars eight minutes round trip. So anything you send to Mars you, gotTa. Weigh eight minutes to figure out what the heck happened or even what happened for your report back. Then you know that's not it doesn't all have to be synchronised. They're asynchronous ways. There are ways to kind of achieved some advantages and key things up, but it's still it's eight minutes basically, and so because of that, there's a video on youtube by the way for your listeners. If you haven't seen it, it's called the seven minutes of terror. Closer to eight. Yeah. Yeah. That's a great one. Yeah. Yeah. That's for the entry descent and landing. When they landed MSL curiosity, they had to use a big sky crane instead of the typical big balloon rap the rover to balloon it let it balance which was the way they did it before it was so big they had to have this elaborate sky crane thing and in that seven minutes when you go into entry descent and landing there seven minutes before you knew, Hey, what the heck happened and all this stuff had to happen autonomously and things like that, which is great. But yeah, normally eight minutes and so if I told you today that the Mars surface operations people use about two. Hundred images a day that are taken from the rover from its NAVC cans, which are camps by the wheels, and it's Mass Cam, which is the big head that take selfies and other things that you see what it's arm. If I told you that today, they only use two hundred images to plan what to do for rover operations. The next day you'd understand why we're bandwidth limited or Ltd what we can process on the reverse sucking them down to the ground and making decisions. What if I told you tomorrow? We'll get close to that nvidia chip maybe not exactly but there's efforts called high-performance space like computing to build a multi-core. GP. Like chip that is radiation hardened. It's a big government project. That has an emulator already that they're making and that we also today have Mars helicopter I'm perseverance, which is a little drone that went along with it that if successful is running a qualcomm snapdragon, which is gp like chip and why are we not fully radiation hardened and all this? It does we've tested in whatever but it's not like has the years and years of testing. Why are we doing that? Because it's a technology demonstration and we have a bigger like the mission is still successful even if Mars Halley you know is not successful with that what you call ingenuity right and I. Suspect that the risk to a little drone helicopter thing
