  Title: Extended Duration Orbiter (EDO) Improved Waste Collection System (IWCS)
  Description:
  This high angle overall view shows the top side components of the Extended 
  Duration Orbiter (EDO) Waste Collection System (WCS) scheduled to fly
  aboard  NASA's Endeavour, Orbiter Vehicle (OV) 105, for the STS-54 mission. 
  Detailed  Test Objective 662, Extended duration orbiter WCS evaluation,
  will verify the  design of the new EDO WCS under microgravity conditions
  for a prolonged  period. OV-105 has been modified with additional
  structures in the waste  management compartment (WMC) and additional
  avionics to support/restrain the  EDO WCS.  Among the advantages the new
  IWCS is hoped to have over the currect  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.  The WCS was documented in JSC's Crew Systems 
  Laboratory Bldg 7.
