Inflatable Surveillance Balls For Mars

Rolling over the Red Planet:
Each foot-wide, 11-pound ball can roll up to 62 miles, snap photos at any angle, and take soil samples, drawing its power from the solar panels on its shell. Unlike wheeled rovers, the rounded scouts have fewer motors to repair, never flip over, and are easier to seal from dust. Plus, they rarely get stuck.
