Morris Twenty Twenty Rover, Mars Twenty, Two Years discussed on Liftoff



So we know that Mars has an atmosphere it's far thinner than ours. And the thought the theory has been that Sola wind basically shifted away over time mavens findings basically back that up and it's also himself looking at water looking at the the ice caps, but maven has an fuel to last through twenty thirty or so so it is being re purposed in part to become a communications relay for the Morris twenty twenty Rover. So instead of having to talk back to earth direc-. Actually, the Rover can talk to maven which convincing data back faster than the river would be able to able to on its own. So to do this. The team is lowering the orbit of maven around Mars. So right now, it's circling Mars like of five point three times a day. It's going to be able to bump it up to six point eight you'll have better coverage more flyovers to get the data from the Rover, and then handed back off to the deep space network when it's incite so sort of getting ready kinda getting things in place and another step towards having a another Rover on the red planet. I love the idea of as I've said on this show before the idea that we've got a bunch of satellites around Mars now, and we can use them for communication, and this is another great example where this thing was only on a relatively short mission two years, but it's still got fuel to spare for more than a decade. And. And they've done. These aero breaking new verse before in order to sample the atmosphere. So just doing it again changing it to be a little bit better. Located for. Doing a job as a relay satellites such a cool thing to have them be flexible in this way. I would imagine that this is something that was talked about all along as part of shaven. But they don't necessarily talk about that stuff publicly. But I think if you're doing game planning for Mars missions, everybody is talking to everybody else about the hardware. That's going to be there when they're there in order to make their missions work. Well, and this this is a cool. Cool bit teamwork. Yeah. Absolutely. So you mentioned the Arab breaking said they're not using a ton of fuel to do this basically just enough fuel to drop a little bit lower than the drag will pull it into the orbit that they want right? That's gonna take like three hundred sixty orbits or two and a half months to slow is very gradual process. But doing that means that they can basic serve that fuel. So if they need to make judgements down the road to say stay in contact with March twenty twenty then they have the fuel. They can. The thrusters then, but they want to reserve that as long as possible, and they can they can do this. With just physics without atmosphere is providing that force slowing them down instead of them just blasting their thrusters. And it's it's brilliant. Yep. -solutely? So so yes, so maven will press on into service for you know, a least another decade. It sounds like servicing Mars twenty twenty and I would assume future Martian programs. You know, like you said everyone's talking other if they're things further down the road for the out. Maybe this isn't the compensation for that as well. Yeah, looks recycling is what I'm saying. It's really good. It's it's it's very cool to see this the robustness of the spacecraft to that's the other thing that strikes me about all this is that you know, I I realized this is part of the game now. But it's the, oh, well, it's gonna last two years or, you know, fifteen. Like, I love that about it. But they need to make them this robust. And if they get them to to work, right? And there aren't equipment failures. They can last a lot longer than than planned. And that's a that's really awesome. So we have to talk about this. I've really was trying to avoid it because I just want to hit head. But there is something telling about the note that I have in this section of our little document being why was this thing?.
