What exactly is life support? Is it somthing on the shuttle or in their suites? Is it just somthing to recreat the environment of Earth? Please can some one elaborate?

The pressure, oxygen, temperature, CO2 removal etc.
mgb_phys said:The shuttle flies with a shirt sleeves atmosphere, you don't need a suit inside it, the suit backpack basically contains smaller versions of the shuttle life support systems.
Interesting - presumably to reduce the pressure load on the suit and stop it doing a 'michelin man', I suppose there isn't much fire risk inside a suit.Janus said:Not quite. While the Shuttle uses a nitrogen-oxygen mix at 1 atm, the suits still use pure oxygen at 4.3 lb/in².

Life support systems are designed to provide the necessary environmental conditions for humans or other living organisms to survive and function. This can include maintaining air quality, regulating temperature and humidity, and providing food and water.
Life support systems typically consist of various technologies and processes that work together to maintain a stable and livable environment. These can include air filtration systems, temperature control systems, water purification systems, and waste management systems.
Understanding life support systems is important for several reasons. It allows us to create and maintain habitable environments for humans and other living organisms, such as in space or underwater. It also helps us to develop more efficient and sustainable technologies for supporting life on Earth.
Some common examples of life support systems include spacecraft life support systems, which provide a livable environment for astronauts in space, and medical life support systems, which assist in maintaining vital functions for patients in critical conditions. Other examples include aquaponic systems, which combine fish farming and plant cultivation to create a sustainable food source, and biosphere projects, which aim to create self-sustaining ecosystems in enclosed environments.
Life support systems can have both positive and negative impacts on the environment. On one hand, they can help to sustain human life in harsh or uninhabitable environments, reducing the need for destructive activities such as deforestation or mining. On the other hand, some life support systems may consume large amounts of resources and produce waste that can harm the environment if not properly managed.
