text: On April 8,2001 Mars Global Surveyor drew a close enough second look. "We had to roll the spacecraft 25 degrees to center the face in the field of view,"Garvin stated. Malin's team captured an extraordinary photo using the camera's absolute maximum resolution. "As a rule of thumb, you can discern things in a digital image three times bigger than the pixel size", Garvin added. "So if there were objects in this picture like airplanes on the ground or Egyptian-style pyramids or even small shacks, you could see what they were!" he added. They could tell there was nothing just the land its self. It could not have been aliens.
