Space Biosciences Research The principal mission of the Space Biosciences Research Branch is to advance space exploration by achieving new scientific discoveries and technological developments in the biological sciences.
This is the only way an efficient life-support system can be developed.
Our research group previously reported the possibility to take advantage of carbon based materials immune properties under microgravity conditions (Crescio et al. The pulse returns to normal much more slowly after acceleration under conditions of weightlessness than after centrifuge experiments on earth. These changes were generally the same as the shifts recorded in the biological subjects studied in low-altitude orbits. Space biology is a synthetic science, having gathered together the advances made in various branches of biology, aviation medicine, astronomy, geophysics, radio electronics, and many other sciences and having based its own research methods on them. There are many different types of space scientists, each with specific purposes that help humanity discover more about the space. This information should not be considered complete, up to date, and is not intended to be used in place of a visit, consultation, or advice of a legal, medical, or any other professional. The death of an animal soon after the premature termination of the flight was attributed by specialists to weightlessness, which resulted in a redistribution of blood, a loss of fluids, and a disturbance of potassium and sodium metabolisms. says Mr. Lionel Suchet, Chief Operating Officer for the CNES (Centre National d’Etudes Spatiales, France). Space biology will also play an extremely important role in the development of the biocomplexes (that is, closed ecological systems of autotrophic and heterotrophic organisms) that will be essential for long flights. Analysis of the statistically significant increase in the frequency of recessive sex-linked lethal mutations in comparison with the total radiation dose received during the flights and with an evaluation of the results of special experiments on the ground showed that the genetic changes observed could not be ascribed solely to radiation but rather to the combined effects of all the factors of space flight (in particular, to the dynamic factors: acceleration, weightlessness, and vibration). What does SPACE BIOLOGY mean? These experiments were used to study the possibility of creating the conditions essential for animals to live in pressurized cabins (or in special suits in nonpressurized cabins) and to devise methods of ensuring safety during flight, ejection, and parachuting from great heights.
However, owing to the weak penetrating capacity of ultraviolet radiation, a sealed, pressurized spacecraft cabin provides adequate protection against this radiation. the group of mostly biological sciences that study (1) the characteristics of the vital activities of terrestrial organisms under space conditions and during flights on spacecraft (space physiology, ecophysiology, and ecobiology); (2) principles for constructing closed ecological biological life-support systems for the crew of spacecraft and space stations; and (3) extraterrestrial forms of life (exobiology).

A term for the various biological sciences and disciplines that are concerned with the study of living things in the space environment. Work is under way on the joint Soviet-American Osnovy kosmicheskoi biologii i meditsiny (Principles of Space Biology and Medicine). Experiments on lunar flights were the next stage in the research program. Space scientists can specialize in many different fields that relate to the study of space, planets and life in the universe, including astrophysics, biology, chemistry, geology, meteorology and physics.
Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine.
Tissue cultures and other biological objects were kept in incubators with automatic temperature control. The goal of this website is to promote space biology education to university professors and grade 6-12 educators on a national level. Headquartered in Bordeaux, France, Space Biology Unlimited is comprised of a team of 15 people, bringing together multidisciplinary scientists and technical expertise. Both the mean pulse rates and the absolute pulse rates were lower with weightlessness than with the corresponding experiments on earth. The dogs were provided with a jellylike food from automatic feeders; the small laboratory animals had free access to the food and water. The total irradiation dose was approximately the same on all of the flights. Definitions.net. Control animals were observed for all of the experiments under the same conditions, except weightlessness, as the animals in flight. In addition, the rates fluctuated considerably. These experiments were designed to study, in the absence of the screening effect of the earth’s magnetic fields and atmosphere, the biological effects of the ionizing radiation of the Van Allen belts and of the considerable amounts of primary cosmic radiation and protons from solar flares.
