Launched into earth orbit on May 14, 1973, Skylab was a research center that housed three-man crews on three different visits to the space station. The longest mission lasted nearly three months.
Equipment and experiments on board the orbiting station were designed to accommodate four areas of research: earth observation to further knowledge of natural resources and the earth’s environment; solar observation to increase understanding of solar processes and influences on earth’s environment; study of the effects of long duration weightlessness on man, basic biological processes and adaptability to space flight conditions; and experiments in processing of materials under the unique conditions of weightlessness and vacuum environment of space. All missions were highly successful in obtaining data and photographs.
Skylab consisted of four major components: the Orbital Work Shop (OWS), Airlock Module (AM). Multiple Docking Adapter (MDA), and the Apollo Telescope Mount (ATM).
The cylindrical Orbital Work Shop is 15 meters (48 feet) in length and 6.5 meters (22 feet) in diameter. The workshop is divided into two major areas by an open-grid partition. By wearing special shoes, the astronauts can use this grid to anchor themselves in the weightlessness of space. The lower portion contains the crew quarters, food preparation and dining areas, washroom, and waste processing and disposal facilities.
