The Mars Pathfinder
The Mars Pathfinder was the second of NASA's low-cost planetary Discovery missions. It landed in 1997 and sent back fascinating images that confirmed that Mars once had a great deal of water on its surface. The roving robot, Sojourner, wheeled around the surface and found rocks with compositions very similar to Earth rocks.
Take an exploratory journey with the Mars Pathfinder. Determine the coordinates of the Mars Pathfinder landing site.
