About The Cover

Pathfinder on Mars. The Sojourner Rover deploys the -proton x-ray spectrometer onto the rock named Moe within the rock garden in this 75-image, color-enhanced mosaic taken by the imager on the lander. (Image of the rover in the rock garden was taken on a different day than the terrain image.) The view is to the southwest, with the Carl Sagan Memorial Station in the foreground and South Twin Peak on the horizon about 1 km from the lander. See the special section beginning on 1734.
