In the Orbiter Processing Facility-2 at NASA's Kennedy Space Center in Florida, STS-134 Mission Specialists Andrew Feustel, left, Michael Finke and Greg Chamitoff look at space shuttle Endeavour's heat shield tiles, which will protect the spacecraft during re-entry. 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.

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
