Step-2 proposals for the Mars Science Laboratory Participating Scientist Program are due November 5, 2021.

The purpose of the Mars Science Laboratory (MSL) Participating Scientist (PS) program is to enhance the scientific return from the mission by broadening participation in the mission and mission operations. The program solicits new investigations that broaden and/or complement the funded Principal Investigator (PI)-led instrument investigations, thus maximizing the contribution of MSL to the future exploration and scientific understanding of Mars. Participating Scientist proposals may include instrument-specific or multi-instrument investigations and, in all cases, must include both science analysis and an operational component (commitment to participate in daily operations).
