Facility 1 Mission Specialist Sandy Magnus inspects a tool she'll use in space.

In Orbiter Processing Facility-1 at NASA's Kennedy Space Center in Florida, STS-135 Mission Specialist Sandy Magnus inspects a tool she'll use in space. 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 the tools and equipment they'll use and familiarization of shuttle Atlantis' payload they'll deliver to the International Space Station.

Atlantis is being prepared for the STS-135 mission, which will deliver 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. Photo credit: NASA/Kim Shiflett
