On Saturday, February 1, 2003, Space Shuttle Columbia disintegrated as it re-entered the atmosphere over Texas and Louisiana, killing all seven astronauts on board.It was the second Space Shuttle mission to end in disaster, after the loss of Challenger and crew in 1986.
Astronautical hygiene evaluates, and mitigates, hazards and health risks to those working in low-gravity environments. [1] The discipline of astronautical hygiene includes such topics as the use and maintenance of life support systems, the risks of the extravehicular activity, the risks of exposure to chemicals or radiation, the characterization of hazards, human factor issues, and the ...
Since the Moon is now generally considered to be free from life, the most likely source of contamination would be from Mars during either a Mars sample-return mission or as a result of a crewed mission to Mars. The possibility of new human pathogens, or environmental disruption due to back contamination, is considered to be of extremely low ...
Parts of the shattered shuttle rained down across a broad expanses, much of it over Hemphill, Texas. The disaster was attributed to a a piece of foam that fell from the external rocket tank during ...
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. [1] It is possible to classify these microorganisms into two groups, the human-borne and the extremophiles.
The Space Shuttle Columbia was lost as it returned from a two-week mission when previously detected damage to the shuttle's thermal protection system (TPS) resulted in the spacecraft breaking apart during reentry at an altitude of just under 65 km and a speed of about Mach 19. Investigation revealed that a piece of foam insulation had fallen ...
Exposing Microorganisms in the Stratosphere (E-MIST) is a NASA study to determine if a specific microorganism could survive conditions like those on the planet Mars.The study transported Bacillus pumilus bacteria and their spores by helium-filled balloon to the stratosphere of Earth (~31 km above sea level) and monitored the ability of the microorganisms to survive in extreme Martian-like ...
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.
