IML 1

NSSDCA ID: IMGLAB1

Description

The First International Microgravity Mission (IML-1) was the first in a series of missions with payloads dedicated to life science and microgravity science research. It was flown aboard Space Shuttle Discovery, STS-42; it was the 45th Shuttle flight and the 15th flight of Discovery. The primary objective of IML-1 was to conduct science and technology investigations that required the low-gravity environment of space, with emphasis on experiments that studied the effects of microgravity on materials and processes and living organisms. IML-1 was a cooperative effort involving six space research institutions: the National Aeronautics and Space Administration (NASA), the Canadian Space Agency (CSA), the European Space Agency (ESA), the West German Research and Development Institute for Air and Spacecraft (DLR), the French National Center for Space Studies (CNES), and the Japanese National Development Agency (NASDA). More than 200 scientists from 16 countries participated in the investigations. The crew aboard STS-42 consisted of a flight crew composed of the commander, pilot, and a mission specialist; a payload crew composed of two mission specialists; and two payload specialists. The IML-1 payload consisted of 9 materials science investigations and 7 life science experiments most of which were maintained in the onboard Spacelab Long Module. The Long Module, which measured 7 m in length and was connected to the middeck of Discovery by a 5.8 m long tunnel, contained 12 Spacelab racks (10 of which held experiments and stowage containers), and 14 overhead stowage lockers. The Orbiter middeck lockers housed additional experiments and ancillary equipment.
