A comprehensive prelaunch environmental assurance program was planned and implemented on NASA's Mars Exploration Rover (MER) project. This project consisted of two rovers/spacecraft launched on two separate launch vehicles. The environmental assurance program included assembly/subsystem and system-level testing in the areas of dynamics, thermal, and electromagnetic (EMC), as well as venting/pressure, dust, radiation, and micrometeoroid analyses. Due to the Martian diurnal cycles, the susceptible hardware also underwent thermal cycling qualification of their packaging designs and manufacturing processes. This paper presents a comprehensive summary of the environmental assurance program for the MER project. A series of test and analysis metrics are generated. Selections of the numerous lessons that have been learned from implementation of the MER environmental assurance program are documented in this paper. They include both technical and programmatic lessons that would be helpful in improving implementation of the environmental program for future projects.
