Space Shuttle Discovery
Space Shuttle Discovery Shuttle Orbiter Discovery (NASA Designation: OV-103) is a NASA Space Shuttle. First flown on August 30, 1984, Discovery is the third operational shuttle (excluding test shuttle 'Enterprise'). The orbiter is still operational today, and has performed both research and International Space Station (ISS) assembly missions. The craft takes its name from a ship used by explorer James Cook.

Meanwhile the Air Force had a continuing interest in smaller systems with more rapid turn-around times, and were involved in their own spaceplane project called Dynasoar. In several instances groups from both worked together to investigate the state of the art.

Spacelab
Spacelab is a microgravity laboratory flown into space on the Space Shuttle. It consists of a large cylindrical main laboratory that is flown in the rear of the Space Shuttle cargo bay, connected to the crew compartment by a long tube. In April 1973 NASA and the ESA (then known as the ESRO) agreed to build a modular science package. Construction of Spacelab started in 1974 by the ERNO (represented by VFW-Fokker GmbH, later bought by MBB, and since 2003 part of EADS Space Transportation). The first lab, LM1, was given to NASA free of charge in exchange for flight opportunities for european astronauts. A second lab, LM2, was bought by NASA for its own needs. The system also included a system of external pallets for experiments in vacuum, built by

Christa McAuliffe
was a American teacher and astronaut from New Hampshire who died in the explosion of the Space Shuttle Challenger on STS-51-L. She was born Sharon Christa Corrigan in Boston, Massachusetts. McAuliffe was selected to be the first teacher in space on July 19, 1985. She joined the STS-51-L crew as a mission specialist with plans to teach lessons from space. Selected from among more than 11,000 applicants from the education profession for entrance into the astronaut ranks, McAuliffe had been born the oldest child of Edward and Grace Corrigan. Her father was at that time completing his sophomore year at Boston College, but not long thereafter he took a job as an assistant comptroller in a Boston department store and the family moved to the Boston suburb of Framingham. As a
