Amendment 57: C.17 Planetary Science Enabling Facilities Program deferred to 2022

Program element C.17 the Planetary Science Enabling Facilities (PSEF) Program allows proposals for experimental and analytical facilities to be made available to the community that does research under the programs supported by the Planetary Science Division in the Science Mission Directorate of NASA. Proposals must clearly articulate the scientific value of the research facilities that would be made available, as well as demonstrate that there is a significant need and user base for the facility within the community.

ROSES-2021 Amendment 57 announces that C.17 Planetary Science Enabling Facilities (PSEF), which was TBD, will not be solicited in ROSES-2021. However, it will be solicited in ROSES-2022.

On or about December 15, 2021, this Amendment to the NASA Research Announcement "Research Opportunities in Space and Earth Sciences (ROSES) 2021" (NNH21ZDA001N) will be posted on the NASA research opportunity homepage at and will appear on SARA's ROSES blog at:
