Summary
MARS EXPLORER ROVER B, also known as Opportunity Rover, is an American satellite manufactured by JPL and launched on July 8, 2003, from AFETR SLC17B using a Delta 7925H launch vehicle. It has a length of 1.4 meters, a diameter of 1 meter, and a span of 1.4 meters. The dry mass is 185 kg, which is the same as its launch mass. The satellite's configuration includes a spin-stabilized cruise stage, an airbag-cushioned lander, and a rover. Its power source consists of solar cells and batteries for both the cruise stage and fixed solar arrays with batteries for the rover. The mission purpose was to explore Mars through landing and roving on its surface. It has been operational well beyond its 3-month design lifetime.
