Biological and Medical Research in Space


Book Description

Life Science studies in space were initially driven by the need to explore how man could survive spaceflight conditions; the effects of being launched un der high accelerations, exposed to weightlessness and radiation for different periods of time, and returned to Earth in safety. In order to substantiate the detailed knowledge of potentially adverse effects, many model experiments were launched using organisms which ranged from bacteria, plants, inverte brates, rodents and primates through to man. Although no immediate life threatening effects were found, these experiments can be considered today as the precursors to life science research in space. Many unexplained effects on these life forms were attributed to the condition of weightlessness. Most of them were poorly recorded, poorly published, or left simply with anecdotal information. Only with the advent of Skylab, and later Spacelab, did the idea emerge, and indeed the infrastructure permit, weightlessness to be considered as an ex tended tool for research into some fundamental mechanisms or processes as sociated with the effect of gravity on organisms at all levels. The initial hy pothesis to extrapolate from hypergravity through 1 x g to near 0 x g effects could no longer be retained, since many of the experiment results were seen to contradict the models or theories in the current textbooks of biology and physiology. The past decade has been dedicated primarily to exploratory research.




Life in Space


Book Description

A little-known yet critical part of NASA history Life in Space explores the many aspects and outcomes of NASA’s research in life sciences, a little-understood endeavor that has often been overlooked in histories of the space agency. Maura Mackowski details NASA’s work in this field from spectacular promises made during the Reagan era to the major new directions set by George W. Bush’s Vision for Space Exploration in the early twenty-first century. At the first flight of NASA’s space shuttle in 1981, hopes ran high for the shuttle program to achieve its potential of regularly transporting humans, cargo, and scientific experiments between Earth and the International Space Station. Mackowski describes different programs, projects, and policies initiated across NASA centers and headquarters in the following decades to advance research into human safety and habitation, plant and animal biology, and commercial biomaterials. Mackowski illuminates these ventures in fascinating detail by drawing on rare archival sources, oral histories, interviews, and site visits. While highlighting significant achievements and innovations such as space radiation research and the Neurolab Spacelab Mission, Mackowski reveals frustrations—lost opportunities, stagnation, and dead ends—stemming from frequent changes in presidential administrations and policies. For today’s dreams of lunar outposts or long-term spaceflight to become reality, Mackowski argues, a robust program in space life sciences is essential, and the history in this book offers lessons to help prevent leaving more expectations unfulfilled.

Cells in Space


Book Description

Discussions and presentations addressed three aspects of cell research in space: the suitability of the cell as a subject in microgravity experiments, the requirements for generic flight hardware to support cell research, and the potential for collaboration between academia, industry, and government to develop these studies in space. Synopses are given for the presentations and follow-on discussions at the conference and papers are presented from which the presentations were based. An Executive Summary outlines the recommendations and conclusions generated at the conference.




Spaceflight in the Shuttle Era and Beyond


Book Description

An exploration of the changing conceptions of the iconic Space Shuttle and a call for a new vision of spaceflight The thirty years of Space Shuttle flights saw contrary changes in American visions of space. Valerie Neal, who has spent much of her career examining the Space Shuttle program, uses this iconic vehicle to question over four decades' worth of thinking about, and struggling with, the meaning of human spaceflight. She examines the ideas, images, and icons that emerged as NASA, Congress, journalists, and others sought to communicate rationales for, or critiques of, the Space Shuttle missions. At times concurrently, the Space Shuttle was billed as delivery truck and orbiting science lab, near-Earth station and space explorer, costly disaster and pinnacle of engineering success. The book's multidisciplinary approach reveals these competing depictions to examine the meaning of the spaceflight enterprise. Given the end of the Space Shuttle flights in 2011, Neal makes an appeal to reframe spaceflight once again to propel humanity forward.




Biological Experiments in Space


Book Description

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
