When Deke Slayton was grounded from the Mercury Seven due to a heart condition, he took on the position of Coordinator of Astronaut Activities and informally held the title of "chief astronaut". In this role, he held responsibility for the operation of the astronaut office.[1]

The position of Chief of the Astronaut Office was officially created in November 1963, when Alan Shepard was named as the first Chief Astronaut. His responsibilities included monitoring the coordination, scheduling, and control of all activities involving NASA astronauts. This included monitoring the development and implementation of effective training programs to assure the flight readiness of available pilot and non-pilot personnel for assignment to crew positions on manned space flights; furnishing pilot evaluations applicable to the design, construction, and operations of spacecraft systems and related equipment; and providing qualitative scientific and engineering observations to facilitate overall mission planning, formulation of feasible operational procedures, and selection and conduct of specific experiments for each flight.[2]

Since the Shuttle era, the Chief of the Astronaut Office often returns to active duty in the Office once their term is complete. The Chief is currently responsible for managing Astronaut Office resources and operations, and helps develop astronaut flight crew operation concepts and crew assignments for future spaceflight missions.[3]
