When it comes to "on the ground" exploration of Mars, rovers make pretty good advance scouts. From Pathfinder to Perseverance, we've watched as these semi-autonomous robots do what human explorers want to do in the future. Now, engineers are studying ways to expand rover exploration on Mars. One thing they're thinking about: communication satellite constellations for Mars surface navigation.
The current generation of Mars rovers landed in easily accessible places. Other Martian regions, such as the poles, or Valles Marineris, remain pretty much untouched. That's partly because they're difficult to reach and their weather conditions present challenges. The poles hold a lot of clues to the Martian climate system. Although one cap is known to be mostly water ice, both caps could contain (or be hiding) additional water either in underground lakes or frozen beneath the caps.
