S92-46726 (November 1992) --- A high angle view of the Improved Waste Collection System (IWCS) scheduled to fly aboard NASA's Space Shuttle Endeavour for the STS-54 mission. Among the advantages the new IWCS is hoped to have over the current WCS are greater dependability, better hygiene, virtually unlimited capacity and more efficient preparation between Shuttle missions. Unlike the previous WCS, the improved version will not have to be removed from the spacecraft to be readied for the next flight.
