This solicitation is for Mars Science Laboratory (MSL) Participating Scientist (PS) investigations to enhancethe scientific return from the mission by broadening participation in the mission to include new investigations that broaden and/or complement the funded Principal Investigator (PI)-led instrument investigations, thus maximizing the contribution of MSL tothe future exploration and scientific understanding of Mars. ParticipatingScientist proposals may include investigations that are instrument specific or multiinstrument in nature and, in all cases, must include both science analysis and an operational component (commitment to participate in daily operations) in orderto be considered. Because the intention is to enhanceand broaden the scientific return, investigations submitted by MSL Instrument PIs and Instrument Co-Investigators (Co-Is)will not be considered. Existing Participating Scientists and their PS investigation team members, if they are interested in continuing as Participating Scientists, must propose and successfully recompete.
 
Mandatory Step-1 proposals are due by May 6, 2015, and full Step-2 proposals are due by June 3, 2015.
