Rover Ridge
Mars is too far away to drive Dot the rover live, so you write a program, send it by radio and watch Dot run it. The rocks, craters and ice are somewhere different at every landing site, so a plain list of moves only works once: Dot needs sensors, if / else decisions and loops that stop at the right moment. Six regions lead from the Landing Plain down into the Great Canyon, where something amazing is hiding under the ice.
