Integrated Maneuvering Life Support System
The Integrated Maneuvering Life Support System was essentially a small, free-flying spacecraft. It was designed by United Aircraft's Hamilton Standard Division for use aboard the USAF's Manned Orbiting Laboratory (1963-1969). IMLSS featured propulsion and life support independent of the MOL space station, but it could also operate connected to the MOL via an umbilical. The Department of Defense canceled the MOL project before protective outer thermal garments for this unit were created. IMLSS experience contributed to NASA's current Shuttle Extravehicular Mobility Unit. (U.S. Air Force photo)
