In human spaceflight, a life support system is a group of devices that allow a human being to survive in space. US government space agency NASA, and private spaceflight companies use the term environmental control and life support system or the acronym ECLSS when describing these systems for their human spaceflight missions. The life support system may supply air, water and food. It must also maintain the correct body temperature, an acceptable pressure on the body and deal with the body's waste products. Shielding against harmful external influences such as radiation and micro-meteorites may also be necessary. Components of the life support system are life-critical, and are designed and constructed using safety engineering techniques.

Famous quotes containing the words life, support and/or system:
“Whatever, in fact, is modern in our life we owe to the Greeks. Whatever is an anachronism is due to mediaevalism.”
—Oscar Wilde (1854–1900)
“Many people now believe that if fathers are more involved in raising children than they were, children and sons in particular will learn that men can be warm and supportive of others as well as be high achievers. Thus, fathers’ involvement may be beneficial not because it will help support traditional male roles, but because it will help break them down.”
—Joseph H. Pleck (20th century)
“It would be enough for me to have the system of a jury of twelve versus the system of one judge as a basis for preferring the U.S. to the Soviet Union.... I would prefer the country you can leave to the country you cannot.”
—Joseph Brodsky (b. 1940)
