<p>Reverted edit of RolriCdomt, changed back to last version by Rxke</p> <p><b>New page</b></p><div>Closed Loop [[Life Support Systems]] are environmental control systems which maintain a livable environment in a sealed enclosure, such as a spacecraft, and fully [[recycling|recycle]] all [[supplies]] used in that environment. All materials used by the life support system must be contained within the environment and mechanism. These systems are referred to as &#039;closed loop&#039; in reference to flow charts detailing the theoretical flow of materials through such a system. While modern spacecraft and submarine life support systems have become quite efficient at maintaining livable environments and recycling certain materials (such as water), to date only one type of closed loop life support system has matched the performance of man-rated systems already in use: Controlled Ecological Life Support Systems, or [[CELSS]].<br /> <br /> CELSS&#039;s employ living organisms, such as plants and bacteria, as part of their recycling process. These systems attempt to maintain an ecology in miniature, taking advantage of natural cycles to provide [[food]], [[water]], and other supplies to the crew using their processed waste as a material source. CELSS&#039;s typically use a [[greenhouse]], compost pile (see [[soil]] for a brief discussion of compost piles), and other biologically based processing systems instead of disposal or chemical alternatives. Because it can theoretically be started from seed stock which can be imported at low mass, some type of ISRU augmented CELSS is generally favored for long term life support of a [[Martian Colony]]. However, fully operational CELSS&#039;s tend to be more massive than other life support systems.<br /> <br /> [[Open Loop Life Support Systems]] remain a viable alternative to closed loop systems. However, these cannot function indefinitely without a source of supplies, such as would be available from in situ resource utilization ([[ISRU]]). Closed loop life support systems theoretically only lose material to leakage, and can therefore function far longer on the same amount of supplies than an open system.<br /> <br /> == New Mars Forum Discussions ==<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=228 Designer Plants on Mars]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=4010 Rotating Circular Greenhouse]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=3941 Martian Settlement with a Few Hundred People]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=255 Food for Survival&#039;s Sake]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=3794 Biowaste Powered Batteries]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=229 Eat Like a Martian]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=224 Biodiesel from Algae]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=226 Closed Loop Life Support Systems for ISS and Mars]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=298 China&#039;s Space Vegetables]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=271 Gourmet Cooking en route to Mars]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=297 NASA Water Recycling]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=232 Learn to Live on Mars from Sudbury]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=231 Nutrition]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=269 Constructing a Larger Settlement - One Idea]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=287 Artificial Food Production]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=256 Food! - Marsians = Vegetarians]<br /> <br /> [http://newmars.com/forums/viewtopic.php?t=213 Pizzas!
