Pathfinder’s Science Opens Martian Past SpaceDaily

The Mars Pathfinder mission was launched on December 4, 1996, and landed safely on Mars July 4, 1997. Intended mainly as a demonstration of a low cost entry, descent, and landing technique, Pathfinder operated for over three months, well beyond the one month period that had been planned for the lander and one week for Sojourner, the first rover vehicle to explore Mars.
