ISS ECLSS
The International Space Station (ISS) Environmental Control and Life Support System (ECLSS) is a life support system that provides or controls atmospheric pressure, fire detection and suppression, oxygen levels, proper ventilation, waste management and water supply. It was jointly designed and tested by NASA's Marshall Space Flight Center, UTC Aerospace Systems, Boeing, Lockheed Martin, and Honeywell. The system has three primary functions: Water Recovery, Air Revitalization, and Oxygen Generation, the purpose of which is to ensure safe and comfortable environments for personnel aboard the ISS. The system also serves as a potential proof of concept for more advanced systems building off of the ECLSS for use in deep space missions. Water recovery systems The ISS has two water recovery systems. ''Zvezda'' contains a water recovery system that processes water vapor from the atmosphere that could be used for drinking in an emergency but is normally fed to the ''Elektron' ...

STS-126
STS-126 was the one hundred and twenty-fourth NASA Space Shuttle mission, and twenty-second orbital flight of the ''Space Shuttle Endeavour'' (OV-105) to the International Space Station (ISS). The purpose of the mission, referred to as ULF2 by the ISS program, was to deliver equipment and supplies to the station, to service the Integrated Truss Structure, Solar Alpha Rotary Joints (SARJ), and repair the problem in the starboard SARJ that had limited its use since STS-120. STS-126 launched on 15 November 2008 at 00:55:39 UTC from Kennedy Space Center Launch Complex 39A, Launch Pad 39A (LC-39A) at NASA's Kennedy Space Center (KSC) with no delays or issues. ''Endeavour'' successfully docked with the station on 16 November 2008. After spending 15 days, 20 hours, 30 minutes, and 30 seconds docked to the station, during which the crew performed four Extravehicular activity, spacewalks, and transferred cargo, the orbiter undocked on 28 November 2008.

Carbon Dioxide
Carbon dioxide is a chemical compound with the chemical formula . It is made up of molecules that each have one carbon atom covalent bond, covalently double bonded to two oxygen atoms. It is found in a gas state at room temperature and at normally-encountered concentrations it is odorless. As the source of carbon in the carbon cycle, atmospheric is the primary carbon source for life on Earth. In the air, carbon dioxide is transparent to visible light but absorbs infrared, infrared radiation, acting as a greenhouse gas. Carbon dioxide is soluble in water and is found in groundwater, lakes, ice caps, and seawater. It is a trace gas Carbon dioxide in Earth's atmosphere, in Earth's atmosphere at 421 parts per million (ppm), or about 0.042% (as of May 2022) having risen from pre-industrial levels of 280 ppm or about 0.028%. Burning fossil fuels is the main cause of these increased concentrations, which are the primary cause of climate change.IPCC (2022Summary for pol ...

Nitrogen
Nitrogen is a chemical element; it has Symbol (chemistry), symbol N and atomic number 7. Nitrogen is a Nonmetal (chemistry), nonmetal and the lightest member of pnictogen, group 15 of the periodic table, often called the Pnictogen, pnictogens. It is a common element in the universe, estimated at Abundance of the chemical elements, seventh in total abundance in the Milky Way and the Solar System. At standard temperature and pressure, two atoms of the element chemical bond, bond to form N2, a colourless and odourless diatomic molecule, diatomic gas. N2 forms about 78% of Atmosphere of Earth, Earth's atmosphere, making it the most abundant chemical species in air. Because of the volatility of nitrogen compounds, nitrogen is relatively rare in the solid parts of the Earth. It was first discovered and isolated by Scottish physician Daniel Rutherford in 1772 and independently by Carl Wilhelm Scheele and Henry Cavendish at about the same time. The name was suggested by French chemist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Node 3
''Tranquility'', also known as Node 3, is a module of the International Space Station (ISS). It contains environmental control systems, life support systems, a toilet, exercise equipment, and an observation Cupola (ISS module), cupola. The European Space Agency (ESA) and the Italian Space Agency (ASI) had ''Tranquility'' manufactured by Thales Alenia Space. A ceremony on 20 November 2009 transferred ownership of the module to NASA. On 8 February 2010, NASA launched the module on the Space Shuttle's STS-130 mission. Design and manufacturing ''Tranquility'' was built within the ESA-NASA ISS bartering system. ESA committed to build and fund both Harmony (ISS module), ''Harmony'' and ''Tranquility'' as well as the Automated Transfer Vehicle, ATV in order to use NASA ISS facilities, fly astronauts on the Shuttle and for other ISS services. ESA teamed up with the Italian Space Agency (ASI) to Manufacturing of the International Space Station, manufacture both ''Harmony'' and ''T ...

Activated Carbon
Activated carbon, also called activated charcoal, is a form of carbon commonly used to filter contaminants from water and air, among many other uses. It is processed (activated) to have small, low-volume pores that greatly increase the surface area available for ''adsorption '' or chemical reactions. (Adsorption, not to be confused with Absorption (chemistry), absorption, is a process where atoms or molecules adhere to a surface). The pores can be thought of as a microscopic "sponge" structure. Activation is analogous to making popcorn from dried corn kernels: popcorn is light, fluffy, and its kernels have a high surface-area-to-volume ratio. ''Activated'' is sometimes replaced by ''active''. Because it is so porous on a microscopic scale, one gram of activated carbon has a surface area of over , as determined by gas absorption and its porosity can run 10ML/day in terms of treated water per gram. Researchers at Cornell University synthesized an ultrahigh surface area activated ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pounds Per Square Inch
The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2), is a unit of measurement of pressure or of stress based on avoirdupois units and used primarily in the United States. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately . The pound per square inch absolute (psia) is used to make it clear that the pressure is relative to a vacuum rather than the ambient atmospheric pressure. Since atmospheric pressure at sea level is around , this will be added to any pressure reading made in air at sea level. The converse is pound per square inch gauge (psig), indicating that the pressure is relative to atmospheric pressure. For example, a bicycle tire pumped up to 65 psig in a local atmospheric pressure at sea level (14.7 psi) will have a pressure of 79.7 psia (14.7 psi + 65 psi). When gauge pressure is referenced to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kilopascal
The pascal (symbol: Pa) is the unit of pressure Pressure (symbol: ''p'' or ''P'') is the force applied perpendicular to the surface of an object per unit area over which that force is distributed. Gauge pressure (also spelled ''gage'' pressure)The preferred spelling varies by country and eve ... in the International System of Units, International System of Units (SI). It is also used to quantify internal pressure, stress (physics), stress, Young's modulus, and ultimate tensile strength. The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one Newton (unit), newton per square metre (N/m2). It is also equivalent to 10 barye (10 Ba) in the Centimetre–gram–second system of units, CGS system. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one Bar (unit)#Usage, millibar, and the kilopascal (1 kPa = 1000 Pa), which is equal to one centibar.

Atmosphere Of Earth
The atmosphere of Earth is composed of a layer of gas mixture that surrounds the Earth's planetary surface (both lands and oceans), known collectively as air, with variable quantities of suspended aerosols and particulates (which create weather features such as clouds and hazes), all retained by gravity of Earth, Earth's gravity. The atmosphere serves as a protective buffer between the Earth's surface and outer space, shields the surface from most meteoroids and ultraviolet solar irradiance, solar radiation, keeps it warm and reduces diurnal temperature variation (temperature extremes between daytime, day and night) through heat retention (greenhouse effect), redistributes heat and moisture among different regions via air currents, and provides the atmospheric chemistry, chemical and climate conditions allowing life to exist and evolution, evolve on Earth. By mole fraction (i.e., by quantity of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon ...

STS-107
STS-107 was the 113th flight of the Space Shuttle program, and the 28th(twenty eigth) and final flight of Space Shuttle ''Columbia''. The mission ended on the 1st of February 2003, with the Space Shuttle ''Columbia'' disaster which killed all seven crew members and destroyed the space shuttle. It was the 88th post- ''Challenger'' disaster mission. The flight launched from Kennedy Space Center in Florida on January 16, 2003. It spent 15 days, 22 hours, 20 minutes, 32 seconds in orbit. The crew conducted a multitude of international scientific experiments. The disaster occurred during reentry while the orbiter was over Texas. Immediately after the disaster, NASA convened the ''Columbia'' Accident Investigation Board to determine the cause of the disintegration. The source of the failure was determined to have been caused by a piece of foam that broke off during launch and damaged the thermal protection system ( reinforced carbon-carbon panels and thermal protection tiles) on ...
