Interesting new image of the Arsia Mons pit. The polar pit gullies image is pretty good, too. |

Sense of wonder, other Doug! Sense of wonder! Doesn't the thought of kilometers-long, tens of meters-high Martian caverns still your breath for just a tiny bit?
And I do wonder at the potential of Martian caverns as ecosystems. Yeah, they'd be cold, but the temperature would be stable, which counts for something; there'd be none of that pesky UV and less of those nasty superoxides. While I am inclined to agree that the action's in the really ancient rocks, I have to wonder - might there be lava tubes at the sites of recent eruptions involving water? What might they hold? |
