OK, so at this point we have no idea where astronauts will go next, if anywhere. But in the meantime, armchair astronauts can (to some degree) content themselves with a couple of cool videos put together by Doug Ellison of UnmannedSpaceflight.com from Mars Reconnaissance Orbiter (MRO) data.
One of the products that comes from the MRO HiRISE camera team is a set of digital elevation models (DEMs), essentially high-resolution data sets showing the elevation of swaths of terrain — each about 4 km wide and 8-12 km long. Using these, Doug (or anybody else, for that matter, with some know-how and computer time) could put together video showing what a flyover of the imaged terrain would look like — in a realistic fashion, without exaggeration of elevations (although the color looks flat to me).
The first flyover is of the wall of Mojave crater:
The second is of Athabasca Valles, a channel cut by catastrophic flooding:
Doug says he’s hard at work on more of these flyover videos, so stay tuned…
