OSS has been developing advanced life support technologies for NASA since 1989, including development of cryogenic portable life support systems for future lunar and/or Mars missions. In 1997, NASA integrated an OSS 2-hour liquid air breathing and cooling backpack to an experimental NASA spacesuit. Upgraded and refurbished in 2005, this system has been in continuous use since 1998. Other OSS-developed life support technologies and subsystems include: Cryogenic CO2 scrubbers, liquid oxygen dewars, positive expulsion dewars, cryogenic liquid gauging, and third generation liquid-air portable life support systems.
