For thousands of years different cultures around the world have assigned their own meaning to the Universe. Through research and technology, we have begun to understand the nature and mysteries of the Cosmos. Last year marked the 40(th) anniversary of our first steps on the Moon, and within two decades it is hoped that humankind will have established a settlement on Mars. Space is a harsh environment, and technological advancements in material science, robotics, power generation, and medical equipment will be required to ensure that astronauts survive interplanetary journeys and settlements. The innovative field of bioastronautics aims to address some of the medical issues astronauts encounter during space travel. Astronauts are faced with several health risks during both short- and long-duration spaceflight due to the hostile environment presented in space. Some of these health problems include bone loss, muscle atrophy, cardiac dysrhythmias, and altered orientation. This review discusses the effects of spaceflight on living organisms, in particular, the specific effects of microgravity on the human body and possible countermeasures to these effects.
