Biosatellite Program
NASA's Biosatellite program was a series of three uncrewed artificial satellites to assess the effects of spaceflight, especially radiation and weightlessness, on living organisms. Each was designed to reenter Earth's atmosphere and be recovered at the end of its mission. Its primary goal was to determine the effects of space environment, particularly weightlessness, on life processes at three levels of organization: basic biochemistry of the cell; structure of growth of cells and tissues; and growth and form of entire plants and animals. Biosatellite 1 Biosatellite 1, also known as Biosat 1 and Biosatellite A, was the first mission in the Biosatellite program. It was launched on December 14, 1966, by a Delta G rocket from Launch Complex 17A of the Cape Canaveral Air Force Station. Biosatellite 1 was the first series Biosatellite satellites. It was inserted in an initial orbit of 296 km perigee, 309 km apogee and 33.5 degrees of orbital inclination, with a period 90 ...

Biosatellite 2
Biosatellite 2, also known as Biosat 2 or Biosatellite B, was the second mission in NASA's Biosatellite program for biological research. It was launched on September 7, 1967, by a Delta G rocket from Cape Canaveral Air Force Station in Florida. Biosatellite 2 carried 13 biological experiments involving insects, frog eggs, plants and microorganisms. The mission was ended early because of a tropical storm threat in the recovery area and communication problems between the capsule and ground stations. The main objective of the mission was to determine if the radiation sensitivity of living organisms in space is greater or less than on land, for which disposed of a radiation source in front of the capsule. The satellite is currently the property of the National Air and Space Museum, reference numbeA19731629000 It is currently on loan to the Museum of Science and Industry, Chicago.

Astrobiology Space Missions
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 ...

NASA Programs
This is a list of NASA missions, both crewed and robotic, since the establishment of NASA in 1958. There are over 80 currently active science missions. X-Plane program Since 1945, NACA (NASA's predecessor) and, since 1958, NASA have conducted the X-Plane Program. The program was originally intended to create a family of experimental aircraft not intended for production beyond the limited number of each design built solely for flight research. The first X-Plane, the Bell X-1, was the first rocket-powered airplane to break the sound barrier on October 14, 1947. X-Planes have set numerous milestones since then, both crewed and unpiloted. Human spaceflight NASA has successfully launched 166 crewed flights. Three have ended in failure, causing the deaths of seventeen crewmembers in total: Apollo 1 (which never launched) killed three crew members in 1967, STS-51-L ( the ''Challenger'' disaster) killed seven in 1986, and STS-107 ( the ''Columbia'' disaster) killed seven more ...

NASA Satellites
The National Aeronautics and Space Administration (NASA ) is an independent agency of the US federal government responsible for the civil space program, aeronautics research, and space research. NASA was established in 1958, succeeding the National Advisory Committee for Aeronautics (NACA), to give the U.S. space development effort a distinctly civilian orientation, emphasizing peaceful applications in space science. NASA has since led most American space exploration, including Project Mercury, Project Gemini, the 1968-1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. NASA supports the International Space Station and oversees the development of the Orion spacecraft and the Space Launch System for the crewed lunar Artemis program, Commercial Crew spacecraft, and the planned Lunar Gateway space station. The agency is also responsible for the Launch Services Program, which provides oversight of launch operations and countdown management f ...

Tanpopo (mission)
The Tanpopo mission is an orbital astrobiology experiment investigating the potential interplanetary transfer of life, organic compounds, and possible terrestrial particles in the low Earth orbit. The purpose is to assess the panspermia hypothesis and the possibility of natural interplanetary transport of microbial life as well as prebiotic organic compounds. The collection and exposure phase took place from May 2015 through February 2018 utilizing the Exposed Facility located on the exterior of Kibo, the Japanese Experimental Module of the International Space Station. The mission, designed and performed by Japan, used ultra-low density silica gel ( aerogel) to collect cosmic dust by, which is being analyzed for amino acid-related compounds and microorganisms following their return to Earth.

List Of Microorganisms Tested In Outer Space
The survival of some microorganisms exposed to outer space has been studied using both simulated facilities and low Earth orbit exposures. Bacteria were some of the first organisms investigated, when in 1960 a Russian satellite carried ''Escherichia coli'', '' Staphylococcus'', and ''Enterobacter aerogenes'' into orbit. Many kinds of microorganisms have been selected for exposure experiments since, as listed in the table below. Experiments of the adaption of microbes in space have yielded unpredictable results. While sometimes the microorganism may weaken, they can also increase in their disease-causing potency. It is possible to classify these microorganisms into two groups, the human-borne and the extremophiles. 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. NASA has pointed out that normal adults have ten times as ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
