Editing Space suit (section)

===North Dakota suit===
Beginning in May 2006, five [[North Dakota]] colleges collaborated on a new space suit prototype, funded by a US$100,000 grant from NASA, to demonstrate technologies which could be incorporated into a planetary suit. The suit was tested in the [[Theodore Roosevelt National Park]] [[badlands]] of western North Dakota. The suit has a mass of {{convert|47|lb}} without a life support backpack, and costs only a fraction of the standard US$12,000,000 cost for a flight-rated NASA space suit.<ref>{{cite web |url=http://www.howstuffworks.com/space-suit4.htm |title=How Space Suits Work |last=Freudenrich |first=Craig |website=[[HowStuffWorks]] |date=December 14, 2000 |publisher=[[Discovery Communications]] |location=Atlanta, GA |access-date=June 19, 2013}}</ref>  The suit was developed in just over a year by students from the [[University of North Dakota]], [[North Dakota State University|North Dakota State]], [[Dickinson State University|Dickinson State]], the state [[North Dakota State College of Science|College of Science]] and [[Turtle Mountain Community College]].<ref>{{cite news |title=That's one small step toward Mars mission |first=James |last=MacPherson |url=http://www.signonsandiego.com/uniontrib/20060507/news_1n7suit.html |agency=[[Associated Press]] |work=[[U-T San Diego|The San Diego Union-Tribune]] |date=May 7, 2006 |access-date=June 19, 2013}}</ref> The mobility of the North Dakota suit can be attributed to its low operating pressure; while the North Dakota suit was field tested at a pressure of {{convert|1|psi|kPa Torr|abbr=on}} differential, NASA's EMU suit operates at a pressure of {{convert|4.7|psi|kPa Torr|abbr=on}}, a pressure designed to supply approximately sea-level oxygen partial pressure for [[Respiratory system|respiration]] (see discussion [[#Operating pressure|above]]).
