Expedition 8 Commander and Science Officer Michael Foale conducts an inspection of the Microgravity Science Glovebox. ESA astronaut Thomas Reiter, STS-116 mission specialist, works with the Passive Observatories for Experimental Microbial Systems in Micro-G (POEMS) payload in the Minus Eighty Degree Laboratory Freezer for ISS (MELFI) inside the Destiny laboratory.
A satellite is a subviral agent that depends on the coinfection of a host cell with a helper virus for its replication. Satellites can be divided into two major classes: satellite viruses and satellite nucleic acids. [1] Satellite viruses, which are most
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. [1]
In 1975, NASA's Viking program launched two identical landers to the surface of Mars, each carrying scientific instruments. Their biological experiments included gas chromatography–mass spectrometry to identify the components of Martian soil, analysis of gas exchange with the Martian environment, pyrolytic release of radioactive 14 C to check if carbon fixation occurred, and labelled release ...
The habitability of natural satellites is the potential of moons to provide habitats for life, though it is not an indicator that they harbor it.Natural satellites are expected to outnumber planets by a large margin and the study of their habitability is therefore important to astrobiology and the search for extraterrestrial life.
Ørsted experiment (1820): Hans Christian Ørsted demonstrates the connection of electricity and magnetism by experiments involving a compass and electric circuits. Discovery of electromagnetic induction (1831): Michael Faraday discovers magnetic induction in an experiment with a closed ring of soft iron, with two windings of wire.
Biosatellite 2 carried thirteen biological experiments involving insects, frog eggs, plants and microorganisms. The mission was ended early due to a tropical storm threat. [ 4 ] Despite returning approximately a day early, its 45 hours of earth-orbital flight enabled valid conclusions to be made in the thirteen experiments on board, by ...
The Soviet/Russian Bion program provided U.S. investigators a platform for launching Fundamental Space Biology and biomedical experiments into space. The Bion program, which began in 1966, included a series of missions that flew biological experiments using primates, rodents, insects, cells, and plants on a biosatellite in near Earth orbit.
