What are the effects of space travel?
Space travel and exploration will expose astronauts to environments and stimuli that have unknown effects upon human physiology. Numerous environmental differences, such as microgravity and increased cosmic radiation, are all of profound significance to an astronaut’s health and safety. A vast amount of research has already been conducted to try to ascertain the effects of space flight on living organisms.
