It was launched on Dec. 4, 1996. It was considered to be the first ever successful landing on mars after Viking, with the gap of almost twenty years. It was landed on the place of Mars which was near to place known as Ares Vallis. It has lander and rover. It has the first rover named as Sojourner to prospect mars.
Mars Pathfinder was intended to be an exhibit of the innovation important to convey a lander and a free-extending mechanical meandered to the surface of Mars in a practical and productive way. It brought about images and required data to earth. It worked more than the time expected for Mars Pathfinder to be in the orbit.
