Status of the Regenerative ECLSS Water Recovery System
NASA is completing the development of a regenerative water recovery system (WRS) for the International Space Station (ISS). The major assemblies included in this system are the Water Processor Assembly (WPA) and Urine Processor Assembly (UPA). Test activities have been completed for the system and planning for launch and on-orbit activation is underway. This paper summarizes the status as of April 2008 and describes some of the technical challenges encountered and lessons learned over the past year.
