The STS-134 crew and technicians check out space shuttle Endeavour's payload bay.

In the Orbiter Processing Facility-2 at NASA's Kennedy Space Center in Florida, the STS-134 crew and technicians check out space shuttle Endeavour's payload bay. The six STS-134 astronauts are 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 in space and familiarization of the payload they'll be delivering to the International Space Station.

Endeavour is targeted to launch on the STS-134 mission Feb. 27, 2011. For more information, visit www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html. Photo credit: NASA/Frankie Martin
