In a previous Community Announcement (released April 15, 2016),
NASA’s Science Mission Directorate (SMD) stated its intent to release
a Program Element Appendix (PEA) to the Stand Alone Missions of
Opportunity Notice (SALMON-2). This PEA will solicit proposals for
one instrument investigation to be implemented on the Martian Moons
eXploration (MMX) mission, which is being developed by the Japan
Aerospace Exploration Agency (JAXA) for launch in 2024.

Release of this MMX PEA has been postponed. NASA SMD intends to
release the PEA no earlier than February 1, 2017. The MMX PEA will
be issued as an appendix to the SALMON-3 notice, which is planned
for release before that date.

As previously announced, the purpose of the PEA will be to solicit
proposals for one Principal Investigator (PI)-led science
investigation involving the development of a Neutron and Gamma-Ray
Spectrometer instrument, to be integrated with and deployed on the
MMX spacecraft. Also as previously announced, no other
investigations or instruments are planned for solicitation in
this PEA.
