The Space Shuttle's first super lightweight external tank is moved on a barge by two tug boats toward a pier at Port Canaveral, Fla. The tank is scheduled to undergo processing at Kennedy Space Center for flight on STS-91, targeted for launch in late May. The improved tank is 7,500 pounds lighter than its predecessors and was developed to increase the Shuttle payload capacity on International Space Station assembly flights. The tank was sent from the NASA Michoud Assembly Facility in New Orleans.
