The Mars Exploration Program has issued, in January 2014, a Request for Proposal for round IX of the Mars Critical Data Products program. This RFP provides support for initial landing site surface, atmosphere, and gravity characterization for the Mars 2020 rover mission. The intent is to convert mission data and numerical simulations into products focused on specific landing site targets (to be provided by the program) that will be useful for reducing the risk to the Mars 2020 rover mission. Proposals are due on Wednesday, March 5, 2014.
Details of the RFPs are posted at: https://acquisition.jpl.nasa.gov/rfp/WH-2691-120313/default.htm or https://acquisition.jpl.nasa.gov/bizops/.
