re: CD Roms??
Ahhhh :)
Such is the resolution of HiRISE ( just a bit more than MOC, taking it to the 'out of a helecopter' human level ) that I think ANYTHING it images will be an 'ooOOOoo' moment!
My list is easy. Opportunity, Spirit, Pathfinder, Beagle ellipse, MPL ellipse...and then they can go do some 'science' with it :D
Personally, with the increasing size of the data products coming out of the spacecraft we're sending to Mars, I'm convinced that there's some sort of hard-drive manufacturer / scientist share profit scheme going on :)
