Spacelab This photograph shows activities inside the science module during the Spacelab-1 (STS-9) mission. Left to right are Mission Specialist Robert Parker, Payload Specialist Byron Lichtenberg, Mission Specialist Owen Garriott, and Payload Specialist Ulf Merbold. The overall goal of the Spacelab-1 mission, the first mission of the Spacelab facility, were: (1) To verify the Spacelab system capability, (2) to obtain valuable scientific, applications, and technology data from a U.S./European multidisciplinary payload, and (3) to demonstrate the broad capability of Spacelab for scientific research. More than 70 experiments in 5 disciplines from 14 nations were conducted during the mission. The mission marked the the entry of non-astronaut persornel, called Payload Specialists, into space as working members of the crew. They are fellow scientists representing the international group of investigators using the mission. Mission Specialists are NASA astronauts who have broad scientific training. They operate various Orbiter-Spacelab systems, perform any required activity outside the spacecraft, and support investigations as needed. The Space Shuttle Orbiter Columbia that carried Spacelab-1 was operated by two other NASA astronauts serving as commander and pilot. The STS-9 mission, managed by the Marshall Space Flight Center, was launched on November 28, 1983.
