CAPE CANAVERAL, Fla. – A replacement distillation assembly for the International Space Station's new water recycling system is being checked out in the Space Station Processing Facility at NASA's Kennedy Space Center in Florida. The unit is part of the Urine Processing Assembly that removes impurities from urine in an early stage of the recycling process. It will be flown to the station aboard space shuttle Discovery on the STS-119 mission. Photo credit: NASA/Jack Pfaller
