	Life Support HRTF
		Regenerative life support systems, based on a combination of biological and physicochemical components, may be used on future missions in low-Earth orbit, in transit to other planetary bodies, and on lunar and planetary surfaces.
		The HRTF systems will be designed to support smooth transitioning between these two test phases and will support investigations relating to the evolution of the regenerative life support system from a predominantly physicochemically-based system to one which is predominantly biologically-based.
		Over the next several years, HRTF systems modeling, design, and development activities as well as major facility construction activities will steadily progress, resulting in what is intended to be the state-of-the-art facility for conducting integrated biological and physicochemical life support systems testing with human participation.

	Plant-Based Life Support in Space
		Even Buck Rogers might be surprised to learn that regenerative life support systems based on combinations of biological and physical processes may be key to sustaining humans on future long-term lunar and planetary missions.
		Designing a life support system for space requires what NASA calls the "systems approach." This strategy attempts to harness chemical cycles occurring naturally on Earth--those of carbon, oxygen, nitrogen, and mineral elements--into an artificial, closed bioregenerative microcosm.
		Doing basic research on regenerative systems and understanding how to merge them requires researchers to concentrate on not only the biotechnological but also the physicochemical processes that can be assimilated into a bioregenerative life support system.

		One such simplified system used the CRU-73 breathing regulator that was specially modified to provide pressure at high-G. The success of these modified and somewhat simpler systems resulted directly in a redirecting of the TLSS program’s central goals towards improved G-protection.
		The TLSS helmet and oxygen mask system would be modified for CE, resulting in use of the standard HGU-55/P helmet in which an occipital bladder was installed, and slight modification of the TLSS mask system to reflect smaller, lower-profile connections to the bladder than had existed on the TLSS mask.
		One may think of the HGU-51/P system as a design-inspiring precursor to the TLSS concept and as a TLSS conceptual prototype that lacked the upper body counter-pressure breathing system found on the latter system (that was to become the nucleus of the spin-off Combat Edge development).

	The Market Economy and Its Life - Support System (Site not responding. Last check: 2007-10-08)
		Hundreds of organizations are now hotbeds of free market activity, promoting a set of beliefs on the highest mental and moral plane, and reaching down into the deepest wellsprings of human nature-the firmly rooted aspiration of every man and woman for the elbow room necessary for them if they are to achieve their personal goals.
		We know that this cannot work because it violates the basic law of life, a law as fundamental in human affairs as the law of gravity in Newtonian physics: Each person is in control of his own life, and if he doesn't take charge of himself no one can assume this responsibility for him.
		It was upon a foundation of these basic ideas about the unique sacredness of human life, the efficacy of reason, the reality of free will, the moral law, and the inviolable rights of persons that the solid citizenry of the 18th century structured the free society-with the free market as its economic corollary.

	The Earth's Life-Support System is in Peril
		We are altering our life support system and potentially pushing the planet into a far less hospitable state.
		Because of the magnitudes and rates of change, we are unsure of just how serious our interference with the dynamics of the Earth's system will prove to be, but we do know that there are significant risks of rapid and irreversible changes to which it would be very difficult to adapt.
		The first step toward meeting the challenge presented by global change is to appreciate the complex nature of the Earth's system, the ways in which we are affecting the system, and the economic and societal consequences.

	Definition of Life Support Systems (Site not responding. Last check: 2007-10-08)
		The fundamental attribute of life support systems is that together they provide all of the sustainable needs required for continuance of life.
		Thus life support systems encompass natural environmental systems as well as ancillary social systems required to foster societal harmony, safety, nutrition, medical care, economic standards, and the development of new technology.
		Knowledge of the Earthâs life support systems encompasses diverse fields such as: the natural sciences (like chemistry and biology); social sciences (such as history, economics, law, psychology, archeology, etc.); humanities (literature, civilizations, etc); engineering, and technology.
