CAPE CANAVERAL, Fla. -- This diagram of a space shuttle orbiter's avionics bay 5 shows the location of aft load control assembly-2 (ALCA-2) inside the bay. Space shuttle Endeavour was scheduled to launch on the STS-134 mission to the International Space Station on April 29, but that attempt was scrubbed to allow engineers to assess an issue associated with failed heaters on a fuel line for Endeavour's auxiliary power unit-1 (APU-1). STS-134 will be the final spaceflight for Endeavour. For more information, visit www.nasa.gov/mission_pages/shuttle/shuttlemissions/sts134/index.html. Image credit: NASA
