The Space Shuttle's first super lightweight external tank is on its way to Kennedy Space Center's Vehicle Assembly Building for processing. The tank, which is scheduled for flight on STS-91 in late May, arrived Feb. 3 in Port Canaveral, where it remained until Feb. 6 due to high winds. 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. Major changes to the lighter tank include the use of new materials and a revised internal design. The new liquid oxygen and liquid hydrogen tanks are constructed of aluminum lithium a lighter, stronger material than the metal alloy currently used. The redesigned walls of the liquid hydrogen tank were machined to provide additional strength and stability as well

Under the watchful eyes of technicians, a crane positions the Orion PA-1 Abort Flight Test module for mass properties testing in NASA Dryden's Flight Loads Lab.

Engineers and technicians pore over data during moment-of-inertia testing on the Orion PA-1 Abort Flight Test module in the NASA Dryden Flight Loads Laboratory.

Reporter Julie Flannery of KERO-TV, Bakersfield, interviews NASA Dryden's Orion Abort Flight Test project manager Gary Martin in front of the Orion PA-1 crew module.
