STS-134 Pilot Gregory H. Johnson inspects the windows on space shuttle Endeavour.

In the Orbiter Processing Facility-2 at NASA's Kennedy Space Center in Florida, STS-134 Pilot Gregory H. Johnson inspects the windows on space shuttle Endeavour. 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 with the tools and equipment they'll use in space and familiarization of the payload they'll be delivering to the International Space Station.

Space shuttle 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/Cory Huston
