The past forty years has led to the enrichment of man’s knowledge of the effects of living in space on the human body. While there is much prediction and conjecture about the long-term effect of living in space, there are a number of things that are now known that raise problems are monumental in nature.
Space travel has always remained risky. Not only is life at stake, working in zero gravity devoid of the protective blanket of air that we call the atmosphere, exposes astronauts to the harmful radiations of the Sun. Prolonged stay in the weightless environment causes muscles and bones to weaken. Doctors and scientists across the world are working towards making space journey better for astronauts.
In space, astronauts tend to feel dizzy as they move around. They eat packed or sealed food. The food is specially packaged so that it does not float away. Having a shower is also a difficult task. The water has to be absorbed as the drops of water form a floating ball in the space.
Working in space is still not easy.
Space journey do not always end a happy note. In the Columbia shuttle disaster on February 1, 2003, we lost a remarkable team of promising astronauts.
