2021 Astrophysics Medium Explorer (MIDEX) AO

 

MIDEX AO

The National Aeronautics and Space Administration (NASA) issues this DRAFT Announcement of Opportunity (AO) for the purpose of soliciting proposals for investigations to be implemented through its Astrophysics Explorers Program.
 
Since the early 1990s, the Explorers Program has provided several classes of flight opportunities for addressing astrophysics science objectives. These mission classes are defined by their AO Cost Caps and are designed to increase the number of flight opportunities in response to recommendations from the scientific community. The Medium Explorer (MIDEX) missions of this Announcement of Opportunity have roughly twice the AO Cost Cap of the Small Explorer (SMEX) mission class. Access to space will utilize one of the several commercial launch vehicles provided by NASA.
