New Cave Entrances Seen on Mars

Riding with Robots writes "The Mars Odyssey orbiter has come across what look to be openings to cavernous spaces under the surface of Mars. NASA reports the find is fueling interest in potential underground habitats and sparking searches for caves elsewhere on the Red Planet. These latest images follow other recent discoveries of intriguing places to explore. From the article: 'The find has led some to wonder if these or other caves on the planet may provide shelter to life or former life on the Red Planet. "Somewhere on Mars, caves might provide a protected niche for past or current life, or shelter for humans in the future," said Tim Titus of the U.S. Geological Survey in Flagstaff. These caves, however, likely never hosted life due to the extreme altitude of their location. "Even if life has ever existed on Mars, it may not have migrated to this height," said Cushing.'"

    Well, you could certainly do it with robots; just probably not the robots that we have here right now.

    I don't know if anyone's done much work with rovers that trail umbilicals, so there might be a lot of testing required to get it right (how do you make sure that it can roll the umbilical up, not get it tangled around stuff, maybe even cut and reattach it in an emergency if a rock falls on it or something), but it's fundamentally an engineering problem, certainly not outside our capabilities.

    I think the biggest trick would be getting a fairly large 'base station' with a lot of solar panels close enough to the cave mouth so that the rover wouldn't waste a lot of umbilical distance getting to the cave, but without collapsing or damaging the cave in any way.

If there are caves with single entrances that can be closed off and pressurized (or filled with water, or even oxygen at low pressure), it seems like that would be pretty handy.

      Likely for the same reasons that terrestrial caves aren't all filled, even though we have a lot more erosive, mass-wasting, and probably as much aeolian redistribution (which is to say: water, landslides, and duststorms.) Caves usually form from water flowing downhill, dissolving out the underlying rock, and eventually escaping, which means a lot of caves go upwards from where the entrance is. If the cave doesn't have much or any wind blowing through it -- if it's dead-end -- there's no reason for wind to blow into it. The entrance will fill, but the rest of the cave has very little air communication with the outside. The primary air exchange system in caves is daily/seasonal heating/cooling, which leads to expansion/expulsion and contraction/indraw of air. Four meters inside the cave, there could be a hurricane outside and you'd never know it. Lots, perhaps most, caves have the entrances mostly filled with debris, but it's mostly from material sliding down and building up a pile of junk just under the overhanging lip of the top of the cave entrance. I'd expect something similar, but much more slow, to be happening on Mars, since there is very little, if any, water-based erosion and no tectonic activity to raise mountain slopes above the angle of repose.

      Thanks for providing a more knowledgeable reply.
      The photos of the cave entrances seem to resemble terran sinkholes.
      If so, and if dust has been drifting into them for centuries, one would expect to see them partially filled.
      E.g. the talcum-fine dust settles in the still air a few meters below the topside gale.
      Yet the initial estimates are that the caves are very deep.
      The only earthwise equivalent this non-geologist is aware of are the vertical shafts in Central America.
      It will be interesting to learn whether the caves are ancient, or part of an ongoing process.
      They don't appear to be mere artifacts on the graphics.

      I'd reluctantly put my money on 'ancient'. From what I've read, there aren't enough geologic processes on Mars -- most notably free water and active transpiration to move the water from lowlands up into highlands for it to flow back down again -- to have any hope of currently active cave formation. But the more we find out about Mars, the more we get surprised, so who knows?

      The thing about sinkholes is: they're usually new caves that have collapsed because the ceiling finally got too thin. But, that does argue for at least somewhat recent development. Maybe there's a whole network of caves with free water (or seasonally free...) just under the surface of the planet. Wouldn't that be cool?

      As we begin to search out alternate habitats for when the 'big one' finally hits earth, Martian subterranean caverns with even seasonal running water would be cool indeed.
      Much better than depending upon orbiting vessels or surface structures that are subject to the vagaries of radiation and smaller space debris.
      Think a Martian version of NORAD's Cheyenne Mountain.
      Surface exposure could be limited to maintaining the solar collectors and exploring.
      Perhaps too much to hope for, but still a hope.

    Is this some kind of joke? They vaguely say it could be a good underground habitat? FOR WHAT?! Martian cave rats? Everyone agrees nothing large enough to see with the naked eye lives on Mars, let alone a living "habitat" of bacteria, which I also don't think is the correct use of the word. Or maybe they mean for us to live in? Yeah we'll get to Mars using super advanced technology and then live in a cave? More like a metal tent thing, I mean come on, watch some movies lol. I suppose you could build the tent in the cave though but still they say "habitat" like astronauts will just be sitting on logs around a campfire and fishing inside the cave. This is complete made up speculation by people who don't know what they're talking about. As if we'd go all the way there and rely on having to find a cave to withstand the wind storms otherwise they all die and the mission fails. That's like 100000x the risk Nasa would ever take. Not to mention the apparent risk of martian cave rats of course.
