[1] [2] The 2005 NASA Authorization Act designated the American segment of the International Space Station as a national laboratory with the goal of increasing the use of the ISS by other federal agencies and the private sector. [3] Research on the ISS improves knowledge about the effects of long-term space exposure on the human body.
Similar to sustainability initiatives on Earth, space sustainability seeks to use the environment of space to meet the current needs of society without compromising the needs of future generations. [ 4 ] [ 5 ] [ 6 ] It usually focuses on space closest to Earth, Low Earth Orbit (LEO), since this environment is the one most used and therefore ...
The alchemist and physician J. J. Becher proposed the phlogiston theory.. The phlogiston theory, a superseded scientific theory, postulated the existence of a fire-like element dubbed phlogiston (/ f l ɒ ˈ dʒ ɪ s t ən, f l oʊ-,-ɒ n /) [1] [2] contained within combustible bodies and released during combustion.
Astro microbiology, or exo microbiology, is the study of microorganisms in outer space. It stems from an interdisciplinary approach, which incorporates both microbiology and astrobiology. Astrobiology's efforts are aimed at understanding the origins of life and the search for life other than on Earth.
The Old Fire burning in the San Bernardino Mountains (image taken from the International Space Station). Fire ecology is a scientific discipline concerned with the effects of fire on natural ecosystems. [1]
Fire is the rapid oxidation of a material (the fuel) in the exothermic chemical process of combustion, releasing heat, light, and various reaction products. [1] [a] Flames, the most visible portion of the fire, are produced in the combustion reaction when the fuel reaches its ignition point.
Research to date into human psychological and sociological effects based on on-orbit near-Earth experiences may have limited generalizability to a long-distance, multi-year space expedition, such as a mission to a near-Earth asteroid (which currently is being considered by NASA) or to Mars. In the case of Mars, new stressors will be introduced ...
The Pea galaxies, also known as Green Peas (GPs), are compact oxygen-rich emission line galaxies that were discovered at redshift between z = 0.112 and 0.360. [1] These low-mass galaxies have an upper size limit generally no bigger than 16,300 light-years (5,000 pc) across, and typically they reside in environments less than two-thirds the density of normal galaxy environments.
