Mission Specialist Roberto Vittori and Mark Kelly check out tools and equipment.

In the Orbiter Processing Facility-2 at NASA's Kennedy Space Center in Florida, STS-134 Mission Specialist Roberto Vittori with the European Space Agency, left, and Commander Mark Kelly check out tools and equipment they'll be using in space. The six STS-134 astronauts are at Kennedy participating in the Crew Equipment Interface Test (CEIT), which gives them an opportunity for hands-on training and familiarization of the payload they'll be delivering to the International Space Station.
