Two additional experiments have been selected to fly aboard the NASA/Lockheed Martin Mars Surveyor Orbiter and Lander/Rover craft, to be launched in March and April 2001. Both craft will carry radiation environment experiments, while the Lander will operate a Mars environmental compatibility assessment instrument, which will identify potential undesirable interactions with human exploration and associated hardware. The first Mars Surveyor orbiter and lander craft will be launched in December this year and January 1999.
