This blue-print-style artist's sketch is based on NASA's Mars Curiosity rover, with proposed modifications for NASA's next rover mission: Mars 2020. The rover is designed to investigate key questions about the habitability of Mars, and assess natural resources and hazards in preparation for future human expeditions to the Red Planet . The Mars 2020 rover would be based on the Mars Science Laboratory's Curiosity rover configuration; car-sized, about 10 feet long (not including the arm), 9 feet wide, and 7 feet tall (about 3 meters long, 2.7 meters wide, and 2.2 meters tall) . Its instruments will enable scientists to identify and select a collection of rock and soil samples that will be stored for potential return to Earth in the future. Analysis of such samples in laboratories here on Earth will help determine whether life existed on Mars and help inform planning for human exploration there. The mission is part of NASA's Mars Exploration Program, a long-term effort of robotic explora...
