Astronaut Corps? Based on NASA information and our own research, the panel found that the Astronaut Office (the Astronaut Corps is the subset of people within that of- fice eligible to fly in space) should sup- port six tasks in priority order: •Provide well-trained spaceflight operators to support the NASA flight manifest. •Supply ground support personnel for unique tasks required to support the NASA flight manifest. •Provide support for new program development, ranging from relatively small payloads and equipment to whole new spaceflight designs. •Be a source of operational knowl- edge and corporate memory of human spaceflight.

Flying is why astronauts sign up for this hazardous job. Once Soyuz crew launches resume, probably this month, NASA’s astronauts will continue serv- ing space station tours lasting an aver- age of six months. They will also serve as flight engineers during Soyuz launch and reentry (commanded by a Russian cosmonaut). These fundamen- tal tasks drive most of the training re- quirements for ISS crewmembers. Flying is an obvious and core prior- ity, but even when not actively train- ing for a mission, astronauts directly support their colleagues in space.
