Scheduled for separate launches between May through June 2003, the twin Mars Exploration Rovers will embark on a journey to explore the Red Planet in search of clues to the planet's mysterious past. The rovers will use an airbag landing system and will each have a robotic arm that carries a suite of scientific instruments. Similar to their human counterparts, the rover's suite of instruments or "geologic tool-kit" includes a Rock Abrasion Tool, which serves the same purposeas the geologists' rock hammer and a Microscopic imager, similar to the geologists'magnifying lens. This presentation will focus on the post landing missionplans for the Mars Exploration Rovers when the rovers arrive in January 2004.
