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
