The Sojourner rover was the second space exploration rover to reach another planet, and the first to be deployed. Sojourner's exit from the lander occurred on Sol 2, after its landing on July 4, 1997. As the next sols progressed it approached some rocks which were named (by the scientists) "Barnacle Bill", "Yogi", and "Scooby Doo", after famous cartoon characters. The rover made measurements of the elements found in those rocks and in the martian soil, while the lander took pictures of the Sojourner and the surrounding terrain, besides making climate observations. The Sojourner is a six-wheeled 65 cm long vehicle, 48 cm wide, 30 cm tall and weighs 10.5 kg. When operating, it could move about 500 meters from the lander and its maximum speed reached one centimeter per second. During its 83 sols of operation, it sent 550 photographs to Earth and analyzed the chemical properties of 16 locations near the lander. #exploration #fame #hall #mars #MER #MESUR #NASA #pathfinder #robot #robotics #rover #sittingduck #sojourner #space
