An examination of broken stalagmites and stalactites might generate information on past marsquakes.
Might be an interesting line of inquiry. |

Agreed...would love to see cross-sections of same!
Can you imagine sending a rover into one of these? Talk about autonomous nav...the PI would be biting his or her nails down to the elbow until it finally emerged & called home... -------------------- A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

http://www.stoneaerospace.com is getting ready to send the Depthx submersible robot to autonomously map and navigate in realtime from the map, the ?world's? deepest cenote/solution spring.
Stone also wants to go to the moon...commercially. |

Scientists studying pictures from Nasa's Odyssey spacecraft have spotted what they think may be seven caves on the surface of Mars. Better someone innoculate Glen Cushing with that anti-Ultreya vaccine... -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

Bill Stone is definitely a man to keep an eye on. He wowed the audience at TED 2007 with his plan for a manned exploration mission to Shackleton crater equipped with only enough fuel for the outbound trip pour encourager les explorers to well, like, explore.
He's definitely the man for this job too - he really likes caves for a start. |

I've applied the same accurate technique I did with Ultreya... And the results don't leave me very optimistic... The image obtained is quite similar to some of Ultreya, there, where I thought were in depth features, is as we know, a dune field, a beautiful one, but a dune field... Just see it for the positive side, if I was wrong once I can be wrong twice... Possible cave Ultreya "abyss" -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

If you've taken the cave 'targets' from Themis toward the IR, remember that IR imaging is quite different to VIS imaging and you might see quite strange and odd results. IR imaging at night doesn't show the topography too well and is more about the thermal inertia of the target.

No, those pictures are indeed VIS. Here's the full figure from the abstract, which also includes daytime and nighttime IR.
These are really cool. I can't wait for HiRISE versions. --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

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

Doug,
I'm not sure you have the names matched to the right image as the caption in the abstract says the names are listed clockwise, not according to the alphabetical label (which would've been more intuitive). I looked for them in the HRSC archive through the map interface (I'm at work) and found four in H0979_0000_ND3.IMG, Chloe in H1904_0000_ND3.IMG and Jeanne/Annie in H0968_0000_ND3.IMG. Unfortunately, I don't have access to Gimp here in the office so I couldn't view the images at full res and/or crop for display on the forum. |

I just listed the names in the order they were, and the image numbers in the order they were - ABCFED (with E having two caves and thus two names )
Screw H1904 - that's 1 Gig+....but I've got the other two HRSC obs on the way down. Doug |

H1904 is a pretty dark image anyway.
BTW, Dena is visible at the bottom of the Chloe THEMIS image as well. |

So...this must be Clöhe and Jeanne, right?
About Jeanne I don't know but Clöhe looks like even less of an abyss than my previous image... -------------------- "Ride, boldly ride," The shade replied, "If you seek for Eldorado!"

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 ) No Doug, that is not the way holes in lava tubes work. 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. |
