New Cave Entrances Seen on Mars 110

Posted by Zonk from the oh-good-lord-what-is-that-arrgh dept.
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.'"

      Even if they were in range (they're not), there are two other problems. First, being solar powered, they couldn't go into the caves because they would have no power to get out if they got stuck or lost. Second, there would be no usable radio communication inside a cave because the walls block the waves.

    Are gases or vapors from within clearing the cave entries of dust?

    Are the caves so new or geologically young that they have not yet drifted full?

      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
