In human spaceflight, a life-support system is a group of devices that allow a human being to survive in outer space. US government space agency NASA , [ 2 ] and private spaceflight companies use the phrase "environmental control and life-support system" or the acronym ECLSS when describing these systems. [ 3 ]
The immediate needs for breathable air and drinkable water are addressed by a life support system, a group of devices that allow human beings to survive in outer space. [15] The life support system supplies air, water and food. It must also maintain temperature and pressure within acceptable limits and deal with the body's waste products ...
A diverse range of arguments of how to relate to space beyond human presence have been raised, with some seeing space beyond humans as reason to venture out into space and exploring it, some aiming for contact with extraterrestrial life, to arguments for protection of humanity or life from its possibilities.
Space and survival is the idea that the long-term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space, [1] and that not doing this might lead to human extinction. A related observation is that the window of opportunity for doing this may be ...
An artist's conception shows a terraformed Mars in four stages of development.. Terraforming or terraformation ("Earth-shaping") is the hypothetical process of deliberately modifying the atmosphere, temperature, surface topography or ecology of a planet, moon, or other body to be similar to the environment of Earth to make it habitable for humans to live on.
In interplanetary space, however, it is believed that thin aluminium shielding would give a net increase in radiation exposure; thicker shielding would be needed to block the secondary radiation. [35] [36] Studies of space radiation shielding should include tissue- or water-equivalent shielding along with the shielding material under study.
Studying the human-borne microorganisms is significant for human welfare and future crewed missions in space, whilst the extremophiles are vital for studying the physiological requirements of survival in space. [2] NASA has pointed out that normal adults have ten times as many microbial cells as human cells in their bodies. [3]
Planetary habitability in the Solar System is the study that searches the possible existence of past or present extraterrestrial life in those celestial bodies. As exoplanets are too far away and can only be studied by indirect means, the celestial bodies in the Solar System allow for a much more detailed study: direct telescope observation, space probes, rovers and even human spaceflight.
