text: Later, on April 8, 2001, Mars Global Surveyor was able to capture a photograph with an absolute maximum of 1.56 meters instead of 43 meters per pixel like in the 1976 Viking photo. The picture was ten times sharper than the original Viking photo. Jim Garvin even said, "You can discern things in a digital image 3 times bigger than the pixel size. 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!"
