Rover missions are hard - you need to put them down somewhere where they can safely drive around and measure (hopefully a variety of) interesting things.
Future rovers may have legs as discussed in this answer and the ability of various legged motilities may open access to much more territory. I'm curious roughly how much.
For the various Mars rover missions, I am guessing that maps were made of "interesting" areas and "drivable" areas, and then they were overlaid for simultaneous compatibility, though I am sure it was a far more complex process.
Are there any kind of rough estimates of what areas of Mars would be relatively safe to land a rover so that it could do a substantial amount of driving, and which of those areas, either due to boulders or sand or inclines or other reasons not so safe? Is there anything like a "rover-friendly region map" estimated for Mars available somewhere?
Any chance something like that existsAnother similar question has been posed for the moon?: Are there "rover-friendly region maps" for the Moon?
