Advanced regenerative environmental control and life support systems:  air and water regeneration.
Extended manned space missions will require regenerative life support techniques.  Past U.S. manned missions used nonregenerative expendables, except for a molecular sieve-based carbon dioxide removal system aboard Skylab.  The resupply penalties associated with expendables becomes prohibitive as crew size and mission duration increase.  The U.S. Space Station, scheduled to be operational in the 1990's, is based on a crew of four to sixteen and a resupply period of 90 days or greater.  It will be the first major spacecraft to employ regenerable techniques for life support.  The paper uses the requirements for the Space Station to address these techniques.
