The driver of the external tank transporter maneuvers external tank #120 toward the nearby Turn Basin on NASA’s Kennedy Space Center where the barge Pegasus is waiting (right). The barge will be towed to NASA’s Michoud Assembly Facility in Louisiana for additional modifications. This tank is the first of the newly designed tanks that were delivered to Kennedy. Previously, the tank was stacked with Discovery and, more recently, Atlantis. The tank has already gone through two tanking cycles during tanking tests but was replaced with tank #121 for Discovery’s return to flight mission STS-114.
