Amendment #2 to SALMON-3 creates New proposal opportunity via PEA J: Small Innovative Missions for Planetary Exploration (SIMPLEx).
The Planetary Science Division (PSD) of the Science Mission Directorate (SMD) is releasing Program Element Appendix (PEA) J of the Third Stand Alone Missions of Opportunity Notice (SALMON-3) Announcement of Opportunity (AO) NNH17ZDA004O. The full text of the SIMPLEx PEA is available on the NSPIRES page for NNH17ZDA004O-SIMPLEx.
SALMON-3 is an omnibus AO that provides a solicitation and procurement base for modest investigations, also referred to as Missions of Opportunity (MO), requiring space flight. Amendment #2 to SALMON-3 creates PEA J, which describes the requirements for Small Complete Mission of Opportunity proposals and documents specific requirements for SIMPLEx. Through this PEA, SMD/PSD solicits investigations for a secondary payload small spacecraft to be built and deployed from a primary spacecraft mission, followed by production of high quality and highly useful science data from that SmallSat, analysis of the data and publication of scientific results, and delivery of the data to an appropriate NASA archive.
Participation is open to all categories of organizations (U.S. and non-U.S.), including educational institutions, industry, not-for-profit organizations, Federally Funded Research and Development Centers, NASA Centers, the Jet Propulsion Laboratory, and other Government agencies. However, for PEA J, only U.S. organizations are eligible to propose as the sole or lead organization. Non-U.S. organizations may participate as non-lead organizations collaborating with U.S. leads.
