 Spaceflight Experience 

Kelly’s  first trip into space was as pilot of STS-108. After several delays,  Endeavour lifted off on December 5, 2001, on the final shuttle mission  of 2001. STS-108 Endeavour visited the ISS, delivering over three tons  of equipment, supplies, and a fresh crew to the orbiting outpost. Kelly  and Mission Specialist Linda Godwin used the shuttle’s robotic arm to  lift the Raffaello Multi-Purpose Logistics Module from the shuttle  payload bay and attach it to a berth on the station’s Unity node.  Mission managers extended Endeavour’s flight duration to 12 days to  allow the crew to assist with additional maintenance tasks on the  station, including work on a treadmill and replacing a failed compressor  in one of the air conditioners in the Zvezda Service Module.  Kelly  traveled over 4.8 million miles and orbited the earth 186 times over 11  days and 19+ hours.
