About this opportunity
This Special Notice is a community announcement from the National Aeronautics and Space Administration (NASA) Science Mission Directorate (SMD) regarding the 2025 Astrophysics Small Explorer (SMEX) Announcement of Opportunity (AO). The notice does not constitute a commitment from NASA to take action, but rather serves to inform interested parties about the planned SMEX solicitation.
The purpose of this notice is to provide advance information about NASA's intention to issue a draft AO for the SMEX program in December 2024, with the final AO expected in March 2025. The plan is to select approximately 2-3 investigations for $3M Phase A concept studies in the first step, and then down-select up to 1 SMEX mission to continue into subsequent phases. The Principal Investigator-Managed Mission Cost is capped at $170M, excluding launch services. NASA has not yet approved the issuance of this AO, and any costs incurred by prospective offerors are at their own risk. The SMEX launch readiness is targeted for Q2 2031.
