This graphic is to illustrate the orbital spacecraft flying over the rover on the surface of Mars as if the two spacecraft were communicating.  The graphic depicts an unrealistic view of the Mars Global Surveyor spacecraft flying what appears to be about 10 feet above the Mars Exploration rover, which sits on its lander, soon after landing, before rising up on it's six wheels.  In reality, the orbiter flies 249 miles (400 kilometers) above the surface of Mars.
