In the Vehicle Assembly Building at NASA's Kennedy Space Center, the suspended external tank is lowered into high bay 1 toward the mobile launcher platform. The tank will be mated with the solid rocket boosters, or SRBs, already installed on the platform. Work to remove and replace the feed-through connector on the external tank will be done in parallel with integrated ET/SRB testing in preparation for space shuttle Endeavour to join the stack later in January. The STS-123 mission is targeted for launch on Endeavour in mid-March. The 25th assembly flight to the International Space Station, Endeavour's payload includes the Japanese Experiment Logistics Module Pressurized Section. Photo credit: NASA/Kim Shiflett
