Atlantis Ready For Its Final Mission

Crewmembers for the final Hubble Servicing Mission, STS-125 pose for a photo on the flight deck of Atlantis.
A total of 156 unique individuals flew with Space Shuttle Atlantis over the course of its 33 missions. Because the shuttle sometimes flew crew members arriving and departing Mir and the ISS, not all of them launched and landed on Atlantis.
Astronaut Clayton Anderson, ESA astronaut Leopold Eyharts and Russian cosmonauts Nikolai Budarin and Anatoly Solovyev only launched on Atlantis. Similarly, astronauts Daniel Tani and Sunita Williams, as well as cosmonauts Vladimir Dezhurov and Gennady Strekalov only landed with Atlantis. Only 146 men and women both launched and landed aboard Atlantis.
Some of those people however, flew with Atlantis more than once. Taking them into account, 203 total seats were filled over Atlantis' 32 missions. Astronaut Jerry Ross holds the record for the most flights aboard Atlantis at five.
