Scientists studying pictures from Nasa's Odyssey spacecraft have spotted what they think may be seven caves on the surface of Mars. well I guess that makes habitats a much easier task of creating now, plus with whatever we find in the walls of Valles Marineris. |

That'll teach me to comment without digging first
Some nice Lat-Long info from these... Dena http://themis-data.asu.edu/img/V18053001 Center Latitude-6.084 N Center Longitude239.061 E Chloe http://themis-data.asu.edu/img/V13448001 Center Latitude-4.926 N Center Longitude239.193 E Wendy http://themis-data.asu.edu/img/V17716001 Center Latitude-8.099 N Center Longitude240.242 E Annie http://themis-data.asu.edu/img/V18340001 Center Latitude-6.267 N Center Longitude240.005 E Abbey & Nikki http://themis-data.asu.edu/img/V14334002 Center Latitude-8.498 N Center Longitude240.349 E Jeanne http://themis-data.asu.edu/img/V18315002 Center Latitude-5.636 N Center Longitude241.259 E I can't find any MOC's to match so far - and I'm sure if there were some, they'd be in the abstract. I'm just guessing here - on the possible structure w.r.t. the collapsed lava tubes - and this is possibly the worst 3d visualisation of all time - BUT - perhaps it's something a bit like that ( just not crap ) Doug

They are actual holes in the roof of the tube, and they do indeed often look rather like the ones in the pictures. Have a look at this for example: http://www.hawaiiweb.com/kauai/html/sites/...e_wet_cave.html I happen to know a bit about the subject, being interested in paleontology. Normally lava caves are rather dismal places paleontologically since the acid and often wet environment is very bad for bone preservation. However these holes in the roof are very effective pitfall traps and the talus cone that accumulates below the hole can be very good for fossils. |
