Christopher Cassidy is the current Chief of the Astronaut Office, having served since 2015.

The Chief of the Astronaut Office is the most senior leadership position for active astronauts at the National Aeronautics and Space Administration (NASA). The Chief Astronaut serves as head of the NASA Astronaut Corps and is the principal advisor to the NASA Administrator on astronaut training and operations.

History

When he was grounded from the Mercury Seven due to a heart condition, Deke Slayton 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/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]
