I cross-posted this from the Mars Odyssey forum because it's relevant here.

I thought you guys might be interested in seeing some results from a campaign we've been running to get mosaics of all the proposed MSL landing sites. We've currently got 22 of the potential landing sites made in day/night and vis, and many with thermal inertia. Here's 4 examples with links to the full pages. You can see the rest of them at http://themis.asu.edu/landingsites

Nili Fossae Trough

Holden Crater Fan

Terby Crater

Marwth Vallis

Holden & Terby both look very interesting!!!

Terby would be my favorite, if I had to pick one, due to the varied topography.
