Book excerpt: Biological Experiments in Space: 30 Years Investigating Life in Space Orbit covers investigations of plant, algae, animals, fish, microorganisms and tissue cultures on space flights, beginning with the first orbital space station on Salyut 1. The book includes results on the influence of the entire complex of physical factors associated with spaceflight on biological systems, including analysis of the impact of microgravity on organisms, as well as the effects of electric and magnetic fields. This book offers important insights for researchers of space biology and astrobiology, as well as space agency and industry specialists developing future space stations and missions. Lack of gravity, temperature and chemical gradients, magnetic and electrical fields, spectral composition and intensity of light, and high-energy cosmic radiation influence many important metabolic and physiological processes in animals, plants, and microorganisms, as well as transfer phenomena in and around them. Success of future space exploration depends on understanding the effects of these factors on biological organisms and developing appropriate countermeasures, aimed at improving growth, development, and reproduction in microgravity. - Includes results on the influence of the entire complex of physical factors associated with spaceflight on a range of biological systems - Analyzes the impacts of microgravity, as well as electric and magnetic fields, on organisms - Covers pioneering investigations of plants, algae, animals, fish, microorganisms and tissue culture in space flights
