The STS-135 crew members inspect the cargo that will be loaded into shuttle Atlantis' payload bay.

In the Space Station Processing Facility at NASA's Kennedy Space Center in Florida, the STS-135 crew members inspect the cargo that will be loaded into shuttle Atlantis' payload bay. From left are Mission Specialists Rex Walheim and Sandy Magnus; and Commander Chris Ferguson. The four-member crew is at Kennedy participating in the Crew Equipment Interface Test (CEIT), which gives them an opportunity for hands-on training with tools they'll use in space and familiarization of the payload they'll deliver to the International Space Station.

Shuttle Atlantis is being prepared for the STS-135 mission, which will deliver the Raffaello multi-purpose logistics module packed with supplies and spare parts to the station. Atlantis is targeted to launch June 28, and will be the last shuttle flight for the Space Shuttle Program.
