NASA Langley researchers are conducting novel mechanical testing on a new lightweight aluminum alloy for the space shuttle's external tank. The engineers hope to develop a new material that will reduce the weight of the external tank by 8,000 pounds. Engineers are simulating flight loads on the lightweight tank to help designers better understand how the new lightweight aluminum alloy will perform during an actual shuttle flight. The Success of the Clementine Mission to the Moon. Va. Rustan, the Clementine mission director, will discuss why the Clementine program was started, how it was managed and the implications for future small satellite projects.
