278 Outstanding assistance from the Reduced Gravity O ffice at NASA Johnson Space Center ensured that  the experiment would fly safely. The NASA KSC Prototype Development Laboratory contributed  substantial manufacturing expertise and effort in orde r to produce this experimental payload under tight  schedule constraints. Ground-based  tests at NASA Kennedy Space C enter were supported through  funding from the NASA KSC CDDF program and fr om the ROxygen ISRU project under NASA ETDP.  Finally, the management of the NASA KSC Surface Systems Office and KSC Engineering and Technology Directorates were very supportive of this advanced technology development effort.  In addition all of our industrial partners mentioned in  the paper above, as well as component suppliers  that have often provided invaluable advice and support. Most of all the team of dedicated engineers and technicians must be thanked for their commitment and hard work in order to design, fabricate and test these ISRU systems, often in harsh and demanding field test analog site locations with dust storms, extreme temperatures and long test days.
