S.A.G.A.N.
SAGANet (Social Action for Grassroots Astrobiology Network) is a social and collaborative web platform created to connect scientists and science enthusiasts who share interests in the research and culture of astrobiology. Background SAGANet was founded in 2011 by Blue Marble Space Institute of Science scientists Zach Adam, Julia DeMarines, Heshan Illangkoon, Betül Kaçar, Sanjoy Som, and Sara Imari Walker. It was officially launched on April 12, 2012 (51 years after the first Yuri Gagarin, launch of a human into space and 31 years after the first launch of the Space Shuttle Columbia (STS-1)), and was announced publicly at the 2012 Astrobiology Science Conference. SAGANet is named after the late Carl Sagan (The acronym is used with courtesy of the Carl Sagan Foundation) and builds upon his vision of a citizenry actively engaged in learning about the cosmos. SAGANet is designed to be an immersive virtual community where members interact in an environment of shared lear ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Astrobiology
Astrobiology, and the related field of exobiology, is an interdisciplinary scientific field that studies the origins, early evolution, distribution, and future of life in the universe. Astrobiology is the multidisciplinary field that investigates the deterministic conditions and contingent events with which life arises, distributes, and evolves in the universe. Astrobiology makes use of molecular biology, biophysics, biochemistry, chemistry, astronomy, physical cosmology, exoplanetology, geology, paleontology, and ichnology to investigate the possibility of life on other worlds and help recognize biospheres that might be different from that on Earth. The origin and early evolution of life is an inseparable part of the discipline of astrobiology. Astrobiology concerns itself with interpretation of existing scientific data, and although speculation is entertained to give context, astrobiology concerns itself primarily with hypotheses that fit firmly into existing scientific ...

Yuri Gagarin
Yuri Alekseyevich Gagarin; Gagarin's first name is sometimes transliterated as ''Yuriy'', ''Youri'', or ''Yury''. (9 March 1934 – 27 March 1968) was a Soviet pilot and cosmonaut who became the first human to journey into outer space. Travelling in the Vostok 1 capsule, Gagarin completed one orbit of Earth on 12 April 1961. By achieving this major milestone in the Space Race he became an international celebrity, and was awarded many medals and titles, including Hero of the Soviet Union, his nation's highest honour. Gagarin was born in the Russian village of Klushino, and in his youth was a foundryman at a steel plant in Lyubertsy. He later joined the Soviet Air Forces as a pilot and was stationed at the Luostari/Pechenga (air base), Luostari Air Base, near the Norwegian border, before his selection for the Soviet space programme with five other cosmonauts. Following his spaceflight, Gagarin became deputy training director of the Yuri Gagarin Cosmonaut Training Center, Cos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Space Shuttle Columbia
Space Shuttle ''Columbia'' (OV-102) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the Columbia Rediviva, first American ship to circumnavigate the upper North American Pacific coast and the Columbia (personification), female personification of the United States, ''Columbia'' was the first of five Space Shuttle orbiters to fly in space, debuting the Space Shuttle, Space Shuttle launch vehicle on STS-1, its maiden flight in April 1981. As only the second full-scale orbiter to be manufactured after the Approach and Landing Tests, Approach and Landing Test vehicle ''Space Shuttle Enterprise, Enterprise'', ''Columbia'' retained unique features indicative of its experimental design compared to later orbiters, such as test instrumentation and distinctive black Chine (aeronautics), chines. In addition to a heavier fuselage and the retention of an internal airlock throughout its lifetime, these made ''Columbia'' the heaviest of the fi ...

Carl Sagan
Carl Edward Sagan (; ; November 9, 1934December 20, 1996) was an American astronomer, planetary scientist, cosmologist, astrophysicist, astrobiologist, author, and science communicator. His best known scientific contribution is research on extraterrestrial life, including experimental demonstration of the production of amino acids from basic chemicals by radiation. Sagan assembled the first physical messages sent into space, the Pioneer plaque and the Voyager Golden Record, universal messages that could potentially be understood by any extraterrestrial intelligence that might find them. Sagan argued the hypothesis, accepted since, that the high surface temperatures of Venus can be attributed to, and calculated using, the greenhouse effect.Extract of page 14 Initially an assistant professor at [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
