How many gallons of recycled urine and sweat will NASA astronaut Scott Kelly have drunk during his year in space?http://nyti.ms/1RqTexs

@GGcontre1 Not that many. If cancel all NASA—no Mars rovers, no climate change research—then could pay tuition for 2% of college students.
@GGcontre1 Cost per U.S. citizen for all of NASA is about $60 a year. Not nothing, but small fraction of your taxes.
