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).
