Human Life Support on the ISS [HD]

For the young and the young at heart.
The environmental and thermal operating systems, or ETHOS, monitors the life support system and the cooling system on the International Space Station. Find out from ETHOS operator Tess Caswell about the role of chemistry in making sure the astronauts aboard the space station have oxygen to breathe, water to drink, and a comfortable temperature in which to live and work. NASA Now Minutes are excerpts from a weekly current events program available for classroom use at the NASA Explorer Schools.
