Cardiovascular adaptation to spaceflight
Medicine & Science in Sports & Exercise, 1996This article reviews recent flight and ground-based studies of cardiovascular adaptation to spaceflight. Prominent features of microgravity exposure include loss of gravitational pressures, relatively low venous pressures, headward fluid shifts, plasma volume loss, and postflight orthostatic intolerance and reduced exercise capacity.

Orientation Illusions in Spaceflight
Journal of Vestibular Research, 1997Investigations of spontaneous illusory reactions were carried out during spaceflights of various durations by ANKETA questionnaires (104 cosmonauts). From a total of 104 cosmonauts, 24, in addition, used a dictaphone to record a verbal description of the illusions and their sensations on tape.

Pharmacokinetic Consequences of Spaceflight
Annals of the New York Academy of Sciences, 1991Spaceflight induces a wide range of physiological and biochemical changes, including disruption of gastrointestinal (GI) function, fluid and electrolyte balance, circulatory dynamics, and organ blood flow, as well as hormonal and metabolic perturbations.

The Dangers of Spaceflight [PDF]
, 1989 After all of the concern at the dawn of the space age about the hazards of spaceflight, most of the hazards of the space environment turn out to fall in the category of minor inconveniences. It does seem possible for people to get used to the weightless environment and still work more or less normally.

Spaceflight and the telltale heart
The American Journal of Surgery, 1983Cardiac arrhythmias have not been a common occurrence during manned spaceflights. Cardiovascular deconditioning, on the other hand, is a universal finding both during and after exposure to microgravity. Exercise capability is reduced only in the immediate postflight period as is cardiac output.

Toward the end of his classic book, Interplanetary Flight, Arthur C. Clarke in 1950 was looking ahead to the end of the twentieth century and the prospects for the future of space travel. He noted that to the ordinary man “this planet is still the whole of the universe: he knows that other worlds exist, but the knowledge does not affect his life and ...

The future of human spaceflight
Acta Astronautica, 2001After the Apollo Moon program, the international space station represents a further milestone of humankind in space, International follow-on programs like a manned return to the Moon and a first manned Mars Mission can be considered as the next logical step. More and more attention is also paid to the topic of future space tourism in Earth orbit, which

The human biology of spaceflight
American Journal of Human BiologyAbstractTo expand the human exploration footprint and reach Mars in the 2030s, we must explore how humans survive and thrive in demanding, unusual, and novel ecologies (i.e., extreme environments). In the extreme conditions encountered during human spaceflight, there is a need to understand human functioning and response in a more rigorous ...
