When humans visited the moon, the lunar rover provided an enabling resource that dramatically multiplied the scope of their exploration activities and science yield. Due to longer expected mission durations and Mars’ larger size and higher gravity, rovers will be even more crucial to effective human exploration. Unlike the Apollo program in which rovers were added part way through the program, rovers for Mars can be fully considered and integrated into the development of EVA systems at the outset. Research and mission studies of Mars exploration systems at HSSSI and elsewhere in recent years reflect this thinking. However, specifics have varied widely from small, EVA-assist rovers that are not ridden to large, pressurized rovers intended to support extended traverses over hundreds of kilometers.

This paper describes the results of performance testing of the Vapor Phase Catalytic Ammonia Removal (VPCAR) technology. The VPCAR technology is currently being developed by NASA as a Mars transit vehicle water recycling system. NASA has recently completed a grant to develop a next generation VPCAR system. This grant concluded with the shipment of the final deliverable from Water Reuse Technology Inc. to NASA on August 31, 2003. This paper presents the results of initial performance testing of the VPCAR-EDU. Mass, power, volume, and acoustic measurements are reported. Product water purity analysis for a Mars transit mission and a planetary base simulated wastewater feeds are also reported.
