| Abbreviations | ASTP = Apollo-Soyuz Test Program | STS = Shuttle Transporter System | ISS = International Space Station | Pi = Pilot | MiSp = Mission Specialist (e.g. engineer, physician) |
| Note |
Suborbital spacecraft flights (Mercury MR-3 and MR-4) and inflight aborts (Soyuz 18A, Soyuz-T 10) of missions are counted. First time crew members in the Challenger catastrophe (C. McAuliffe, M. Smith) are listed as well, while Apollo 1 victim R. Chaffee is included for completeness, though not counted. Also not counted as space flights are purely suborbital tourist flights. All X-15 and SpaceShipOne test flights are recorded as suborbital astronaut wings flights, though. |
