STS-108

STS-108 was a Space Shuttle mission to the International Space Station (ISS) flown by Space Shuttle Endeavour. Its primary objective was to deliver supplies to and help maintain the ISS. While at the station, the crew conducted one spacewalk and attached the Raffaello Multi-Purpose Logistics Module to the station so that about 2.7 metric tons (3 tons) of equipment and supplies could be unloaded. The crew later returned Raffaello to Endeavour's payload bay for the trip home.
