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? |

Sense of wonder, other Doug! Sense of wonder! Sense of wonder, indeed. Being of the generation that remembers Mariner 4, these images just blow me away. Mariner 4 laid to rest the Lowelian Barsoom. There were reputable scientists at that time who just wrote Mars off as nothing but another Luna with a wisp of air. "Mars is Dead" proclaimed the NYT. Mariner 4 killed the fantasy, but in place of that, gave us a real world. And that world just gets more complex with each added mission. Look at the HRISE south pole spider imaging. Is this "just" a vertical shaft into the basalt, or a doorway into a nether realm of caverns (fantasy again... or not). Let's find out, and not just write it off. Craig |
