Still on its 76-wheeled orbiter transporter, space shuttle Discovery rests in the transfer aisle of the Vehicle Assembly Building at NASA's Kennedy Space Center. Discovery will be raised from the transporter to a vertical position and lifted into high bay 3. In the bay it will be attached to its external fuel tank and solid rocket boosters in preparation for its upcoming STS-124 mission to the International Space Station. On the mission, the STS-124 crew will transport the Japanese Experiment Module - Pressurized Module and the Japanese Remote Manipulator System to the space station. Launch of Discovery is targeted for May 31. Photo credit: NASA/Troy Cryder
