In the Vehicle Assembly Building at NASA's Kennedy Space Center, external fuel tank 129 is lowered into high bay 1 where it will be mated with the solid rocket boosters. The external tank-SRB stack will be mated in two weeks to space shuttle Endeavour for the STS-126 mission. The STS-126 mission will deliver a Multi-Purpose Logistics Module to the International Space Station. Launch is targeted for Nov. 10. Photo credit: NASA/Jack Pfaller
