Imagine that advances in technology could produce a superior form of virtual reality that would allow you to transport your senses to Mars, so that you could feel yourself walking on its surface, feeling the light Martian breezes, watching the sun set over Olympus Mons or Tharsis Tholus, or admiring temporary rivulets at the edge of the ice cap at the South Pole.
