In the Vehicle Assembly Building at NASA's Kennedy Space Center, external fuel tank 129 is lifted out of the checkout cell to high bay 1where 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
