STS-132 was the 32nd and last planned mission for space shuttle Atlantis prior to discussion of STS-135.  The flight to the international space station delivered a Russian mini-module along with a radiator, airlock, and other parts.

Three spacewalks were successfully completed to store spare parts outside the station, including six batteries, antenna parts, and spares for the robotic arm.

Six astronauts made the trip.

Space shuttle Endeavour's STS-134 mission was an extra flight added specifically to deliver the Alpha Magnetic Spectrometer to the station.

The Alpha Magnetic Spectrometer is a particle physics experiment module that will help researchers study the formation of the universe and search for evidence of dark matter and antimatter.

Six astronauts flew the 16-day mission, which was originally scheduled for September but delayed by problems with the Alpha Magnetic Spectrometer.

NASA used the last remaining fuel tank to fly space shuttle Atlantis on an 'extra' mission, since Endeavour did not need a rescue flight during STS-134.

STS-135 made one last trip to bring supplies to the international space station and also return a bad ammonia pump for study by engineers on the ground.  The mission was the program's last.
