The space rover is an hypothetical development of NASA for exploration of mars. It can also be adapted to other envirorments in future space programs and explorations. It is powered by electricity and new developed graphene batteries. It can transport up to 10 passengers, with a top speed of 50 mph, and will play a major role in mars colonization. Its light weight and modularity allows the rover to be easily assembled and transported. It will provide great help to astronauts, who affectionately nicknamed it The Frog.
