A thought,

So it takes 20 min to send and then another 20 min to receive a response from a martin rover. 40 min to tell the rover to go around a rock. I propose that we take a rocket and load it with rombas, with solar panels for power, and a camera, along with transmission equipment, and just let them lose on mars. It would be awesome, we could deploy like 100 of them and they could roam the planet, also they would "clean" up all the dust on the surface. Just an idea.
