Astronaut Statistics
The right stuff - Who's flown the most hours in space? Who's the fastest man alive?

Astronaut Statistics - as of July 2015


Total space flight time: 48,025 crew-days (131 crew-years)

Total spacewalk time: 175 crew-days


Total persons that have flown in or:

  • Persons who have flown in orbit: 543
  • Additionally, by US Air Force definition (over 50 statute miles altitude - includes X-15, SpaceShipOne flights over that altitude): 11
  • Additional persons who have flown in space by Fédération Aéronautique Internationale (FAI) definition (over 100 km altitude - of X-15 pilots includes only Joseph Walker, who flew two X-15 flights over 100 km, plus SpaceShipOne pilots Melvill and Binnie): 3

Excluded are Space Shuttle Challenger crew members who perished before reaching orbit on their first mission. On two Soyuz missions, launch aborts also occurred. However in both cases the crew members survived the abort and flew in space on later missions.


  • Astronaut with the most space flight time: Padalka - 878 days - 5 flights
  • Single longest spaceflight: Polyakov aboard Mir LD-4 launched 8 Jan 1994 - 437.7 days
  • Most missions: Seven - Chang-Diaz - 7 flights - 62.8 days and Ross - 7 flights - 58.0 days
  • Speed record: 1969-05-26 - 11,107 m/s at 122 km altitude during re-entry - Apollo 10 - Cernan, Stafford, Young
