Mars Science Laboratory Participating Scientist Program (ROSES 2021)

The objective of the Mars Data Analysis Program (MDAP) is to enhance the scientific return from missions to Mars conducted by NASA and other space agencies. These include, but are not limited to, the following missions: Insight, Mars Pathfinder (MPF), Mars Global Surveyor (MGS), Mars Odyssey (MO), Mars Exploration Rovers (MER), Mars Express (MEX), Mars Reconnaissance Orbiter (MRO), Phoenix (PHX), Mars Science Laboratory (MSL), Mars Atmosphere and Volatile EvolutioN (MAVEN), and ExoMars Trace Gas Orbiter (TGO). Any proposal may incorporate the investigation of data from more than one mission. Additional information about these missions, as well as references containing preliminary science results, can be found on the Mars Exploration Program (MEP) The Mars Science Laboratory (MSL) Curiosity rover landed on Mars in August 2012, with the overall science objective to explore and quantitatively assess a local region in Gale Crater, Mars, as a potential habitat for life, past or present. This mission has been successfully operated for over eight years by a large team of scientists and engineers, using an integrated suite of instruments on a rover platform. A list of the prelanding mission description papers and key postlanding science results published by the science team can be found at https://mars.nasa.gov/internal_resources/840/. The rover is expected to remain active for another eight years, although, as time goes by, the rover power provided by the radioisotope thermoelectric generator is expected to continue decreasing linearly.

The purpose of the 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. Proposers are expected to be familiar with the scientific literature stemming from the mission, including peer-reviewed articles and conference presentations. 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) in order to be considered. Because the intention is to enhance and broaden the scientific return, investigations submitted by MSL Instrument PIs and Instrument Co-Investigators (Co-Is) will not be considered. Existing Participating Scientists (PS) and their PS investigation team members, if they are interested in continuing as Participating Scientists, must propose and successfully recompete and are encouraged to do so.
