Nasa, Mark Watney, United States discussed on Space Nuts

Space Nuts


Space nuts once again. I'd like to recognize our patrons for signing up and putting a few dollars a month into the kitty to Cape podcast alive. You wonderful wonderful people. really appreciate it We we're obviously coming to Tucson up more patrons but it's not mandatory but we do. We do particularly want to recognize those who who are enjoying the cost to want to volunteer some some money in the bank. So thank you for that. If you're interested in doing that patriarch dot com slash spice. Nuts is the patron dot com slash space nuts. And it's just fantastic that you feel that strongly about the podcast that you want to contribute financially and we say it so many times what we really do appreciate you very very much doubt. We read absolutely. No it's fantastic to have people to do that now. Maybe NASA should've sort of signing up some patrons to fix the inside Atlanta because it had to figure out how to fix itself now a little while back you and I talked about the fact that it was trying to do a drilling operation and the drill got stock and they didn't have a solution. Well they came up with one. It's it's Classy as a plumber. On blocking pop. In my opinion this is. This is awesome absolutely so the stories. Nasa's insight rover on it landed on the sorry Dylan on the planet. Yes in November twenty eighteen. So it's been there rather more than a year remember that insight is all about is too big main instruments seismometers to listen to Mars quakes. We've actually talked about this successful detection of Mars quakes on the planet. Which is all you know giving us in giving US insight. Of course which is why it's called that into interior structure of Mars but the other big experiment was the thermometer to lower thermometer. I think it goes down about four meters something like that. That's the idea into the Martian soil. This is basically a drill. That Scott Oli delicate equipment inside it. It's technically called a digging program and if you think of something about thirty five centimeters long fifteen inches or thereabouts. It sort of length but maybe in twenty five millimeters this probably got a spike on one end and basically very cleverly designed so that it it sort of vibrates. It's way down into the soil. They idea was that You you would give it. You can give an individual number of strokes to. I think there's a waiting side. I think that's how it works. That kind of a bit like the old pneumatic drills. People used to use to dig up roadways whether the basically a hammer inside it hits the top of his the top of the of the drill bit the sharp on the end and the impact that actually gives the impetus to make whole him whatever it is very similar like about Tada yes prep slightly gentler process. Because you're talking about putting delicate instruments down so the story is a which we've rehearsed many times. It actually got stuck not very far down into an impact. I think we mentioned too that probably Coupla months ago it actually bounced out again and they were worried that they weren't going to be able to get it back in the whole because the probes of popped out over slightly and so the problem was always don't really know what is maybe stop. Why stuck is there a big slab of rock a blocking the way down or is there? Is it a problem of the the itself? Which is the technical term for this probe not being able to grip the soil around the edge in order to give it some leverage which is another fairly viable possibility because Martian soil is not like so on the Earth and anyway the problem has been along that it wasn't actually working until and people did talk slightly. I think slightly jokingly about giving it a clout with the with the Hammer. It's a shovel. My shovel really insight like its predecessor Phoenix. Which is very similar design. Insight has a robotic arm on the end of it. There's this scoop it really is. It looks a bit like a tiny little backhoe shovel. The people talked about that. But they're very worried about doing that. Because out of the top of the the model itself the probe comes all the wiring that connects it to the to the rover. Gay Sorry to say that quite clearly in the photograph that I've yeah that's right. This is the reason a Nice Nassar Picture. That showing exactly that you can see the prob- you can see the wiring coming out of it and in this particular photograph you can also see the backhoe shovel which apparently has been used to give it a good. A good slug thump thump. Yes right which seems to have done the trick. I think it's hilarious. How do we fix this thing? That said it with a spied done. I can imagine them sitting in mission control. And you know you get the whole thing lined up. And of course. It wouldn't happen in real time. Because of the time takes the signals to get they say you're watching this past tense. Really get it positioned would take ages. I suppose and then you push the button to make the thump or whatever it is. I need to sit there and go. Oh I hit it to hod and twenty minutes to see what happens you will try. Esotique what it does. I think actually with with perhaps having a little bit of artistic license here because I think what they what they actually did was used the the This backhoe shovel to push down on the top of it. Just applying pressure I get it doing thing and doing instead. So there's some words here from I don't think a direct quote from Jpl Jet Propulsion Laboratory spokeperson spokesperson. But the text here which actually comes from popular signed while pressing down with the army operates is instructed the Molter dig for twenty five strokes that's enough to make sink down a couple of inches under ideal conditions fifty millimeters of course for those of us here in the in the metric world early images suggests that the mole has doug perhaps half an edge it's about thirteen millimeters although mission planners anxiously waiting more data before they declared the instruments say so the signs are good but the the the the things not home and dry if I can put it that way There is some very nice quotes from One of the mission scientists who was involved with this work whose name I'm trying to find. Its Yeah I'm sorry I can't I can't I can't find this person's name but there is the they referred to this plan z idea of using the shovel but this NASA. Jpl spokesperson talks about. This is being the gardening skills which quite Because they you know the the idea is to to allow the The mole to to to to go all the way down. They've got to do things like covering up the whole that that it said There's a few really interesting aspects of it if if they don't get them all down significantly further the conclusion will be that. There is a rock cornerstone down the block it but the signs at the moment promising more than that. I liked the other solution that Someone suggested in terms of finding a way of dealing with this. Let's ask Mark Watney. Mark Mark. Watney was the character in the book. The Martian got stuck on Mars earliest had to solve all these problems survive. So I think there's the solution asked Mark Watney instead instead. We've we've Lost Tillman spong. Who is the principal investigator? The person who was making those quotes. Yes that's a good quiet. Yeah all right well. Hopefully there'll be some positive news to share about the insight lander. It's it's robotic drill. You're listening to space nuts. Andrew Dunkley with Fred Watson nuts.
