Correction to C.4 Planetary Science Enabling Facilities

C.4 The Planetary Science Enabling Facilities (PSEF) was recently added to ROSES-25. It solicits proposals for experimental and analytical research facilities to be made available to the community that does research supported by the Planetary Science Division.

On or about July 29, 2026, several corrections will be made to C.4 PSEF: Accidentally omitted standard budget requirements have been added to Table C.4-3 and Sections 3.3.3 and 3.5. New text is in bold and deleted text is struck through. The due date remains unchanged: Proposals are due November 10, 2026.

Questions concerning C.4 PSEF may be directed to Michael Lienhard at HQ-PSEF@mail.nasa.gov.
