Scientist K.R. Sridhar and a twenty-member research team at the University of Arizona Aerospace and Mechanical Engineering (AME) Department are building an Oxygen Generating Subsystem (OGS). This unit is set to be launched into Martian atmosphere in January 2002. When the system is on Mars, it will "suck in Martian atmospheric gases--predominantly carbon dioxide--and process them to produce pure oxygen." The site is a news release from Astronomy Online.
