Amendment 19: Martian Moons eXploration mission Participating Scientist Program Final Text and Due Dates

The Martian Moons eXploration (MMX) mission Participating Scientist Program (MMX-PSP) will support scientists at U.S. institutions to participate on the MMX mission, which the Japan Aerospace Exploration Agency (JAXA) is developing for launch in 2024. ROSES-2022 program element C.24 MMX-PSP solicits proposals for science investigations to be carried out during the primary flight and post-flight phases that significantly enhance the overall knowledge obtained from the MMX mission and that address outstanding questions directly related to mission objectives. Two categories of investigations are solicited in this call: Instrument Science and Sample Science.

ROSES-2022 Amendment 19 releases final text and due dates for MMX-PSP, which was previously listed as TBD. Mandatory NOIs are due June 16, 2022, and proposals are due August 16, 2022.

On or about May 16 2022, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2022" (NNH22ZDA001N) will be posted on the NASA research opportunity homepage at
