I don't know if this is news to anyone, but FWIW, after a similar amount of interest about this image on my site, I asked the MRO team for some more info, and received this reply from Nathan Bridges on the HiRISE team, via Suzanne Smrekar:
"1. Yes, HiRISE is planning to image this again. We can't do much about the Sun angle because MRO's orbit is close to 3:00 P.M. and we are near the equator. Seasonal variations mostly affect the solar azimuth at this latitude, not the angle above the surface. However, we can change the angle that MRO looks at the target. So, for our 2nd observation, we will do a large roll to the east in the hopes of seeing the west-facing wall. 2. The two prevailing hypotheses is that this feature is either a deep collapse pit or a "skylight" ( opening) into an ancient lava tube. The location is between Pavonis and Arsia Mons, two large shield volcanoes, so a volcanic origin is appealing." -------------------- |
