This photo shows the waste and hygiene compartment that will be delivered to the International Space Station aboard space shuttle Endeavour on the STS-126 mission. The Russian-built toilet system provides the crew with a second facility on the station, located in the Destiny lab. The unit separately channels liquid and solid waste. While the solid waste goes to a holding tank, a new pair of processing units that Endeavour also will deliver on this mission are set to begin a unique recycling program -- turning crew members’ urine into potable water. Space shuttle Endeavour and its crew of seven are scheduled to lift off at 7:55 p.m. Nov. 14 for the 15-day STS-126 mission. Photo credit: NASA
