Product Launching
Spacelab employed a modular system of pallets and even an Instrument Pointing System that aimed instruments toward the Earth, sun or stars. Here, Spacelab 2 uses pallets and the pointing system. Before Spacelab, instruments were pointed toward particular celestial objects or areas by maneuvering the shuttle to an appropriate attitude. The Spacelab pointing system aimed instruments more accurately than the shuttle and kept them fixed on a target as the shuttle moved. Spacelab 2 was flown on the STS-51F launched on July 29, 1985, aboard the space shuttle Challenger. NASA’s Marshall Space Flight Center in Huntsville, Ala, managed the Spacelab Program and the Spacelab 2 mission.
