discoveries in the stacks

In high bay 3 of the Vehicle Assembly Building at Kennedy Space Center, a crane lowers space shuttle Discovery toward the external tank and solid rocket boosters already stacked on the mobile launcher platform. The stacking and mating took place in preparation for the launch on the STS-124 mission to the International Space Station.

Discovery is targeted to launch May 31. Navy Cmdr. Mark E. Kelly will command the STS-124 shuttle mission to deliver the Pressurized Module and robotic arm of the Japanese Experiment Module, known as “Kibo” (hope).
