The Liberty Star tows the Pegasus barge to Port Canaveral the last leg of its journey from the Michoud Assembly Facility to Kennedy Space Center.

The Liberty Star tows the Pegasus barge to Port Canaveral, the last leg of its journey from the Michoud Assembly Facility in New Orleans to Kennedy Space Center. The barge carries the redesigned external fuel tank that will launch Space Shuttle Atlantis on the next shuttle mission, STS-115. A tugboat will continue the journey upriver to the Turn Basin where, after off-loading, the tank will be moved into the Vehicle Assembly Building and lifted into a checkout cell for further work. The tank, designated ET-118, will fly with many major safety changes, including the removal of the protuberance air load ramps. Photo credit: NASA/Jack Pfaller
