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 Virtual Campus located at: › http://explorerschools.nasa.gov.
