Two tugboats maneuver the Pegasus barge toward the dock in the turn basin in the Launch Complex 39 Area at NASA's Kennedy Space Center. The barge is carrying external tank No. 128 for space shuttle Discovery's STS-124 mission. After offloading, the tank will be transported to the Vehicle Assembly Building, at left. On the STS-124 mission, Discovery will transport the Kibo Japanese Experiment Module - Pressurized Module and the Japanese Remote Manipulator System to the International Space Station. Discovery is targeted for launch on May 25. Photo credit: NASA/Dimitri Gerondidakis
