The excitement in this thread is one thing. Just wait till the kooks get wind of this image. (groan)...don't remind me. I'm traveling now, but next week one of my consipiracy-minded co-workers is going to jump me on this for sure if it hits Hoaxland...at least he's retiring soon! -------------------- 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.

The former; maybe he's tight enough with the latter to persuade him to follow suit? </wishful thinking mode>

38 degrees. Call it 130m across - sohcahtoa and all that - 101 metres is the cutoff at which we wouldn't see light at the bottom.

According to the caption on the image, though, HiRISE should be able to see deeper than that:

Just for grins, I went to HRSCview and located the HRSC image that contains this skylight. Here's a crop from that:
I also noticed another skylight in the same HRSC view: It doesn't look to me like that one's on the Cushing et al list (see my blog entry for that list and image). Or is it? --Emily -------------------- My website - My Patreon - @elakdawalla on Twitter - Please support unmannedspaceflight.com by donating here.

Nice find, Emily! Seems like it's right in line with that (apparent) collapsed lava tube to the upper right...

Ahh, they finally released this picture. The one's got all of the scientists perplexed, we've come to a conclusion it's likely an overhanging of some kind, meaning that the lava tube is really big... I think we've figured it must be at least 200 m deep as well. Still, it's certainly quite a mystery.
Oh, for those of you wanting to overlay MOLA data, it's already been tried, without any luck. |

OK now I see the history of this with Odyssey. Sorry been out of the loop with assorted obligations the past few months.
Besides, THEMIS has photographed just about everywhere on Mars. Good to know. Mike has yet to impliment the Midnight THEMIS Browser , so I haven't been able to keep up on that instrument either. -------------------- If Occam had heard my theory, things would be very different now.

Looks like a good landing site for MSL -- if it stood for the Mars Spelunking Laboratory...

Martian bungee jumping anyone?
Surely this will kick off a more systematic look at the slopes of the Tharsis and Elysium volcanoes, if it isnt already happening. Who know how many of these things might turn up, and who knows how big they might be? Hmmmmm, 0.38 gravity..... P |

Actally, regardless of how deep these things are, at SOME time of the day at SOME time of the year (given their near equatorial location, around local mid day and around the equinoxes) the sun will illuminate the floors of these caverns. Being lucky enough to have an MRO overpass at one of these short periods is another matter of course...
