The first reason why I will not accept this task is that I am not confident piloting a space ship. I have never wanted to become an astronaut. Studying to become an astronaut requires more than high school. NASA asks that candidates have at least three years of professional experience or at least 1,000 hours of …show more content…
Every month an astronaut spends in space they lose approximately 1 percent of their bone mass. This happens because, while in space, there is no gravity. With no gravity astronauts float around from section to section in their space ships; because of this the body starts treating the calcium in the lower limbs, like the legs, like an extra build up. The body will break down the unnecessary calcium and distribute it elsewhere in the body. This redistribution the bones become weaker leading to a brittleness that will affect astronauts when they return into the Earth 's gravity. The bones aren 't the only thing that is affected by zero gravity. Muscles, fluid shifts, the cardiovascular system, and the balance are all also affected by a zero gravity atmosphere. Astronauts are not immune to harm in space and space can cause all manner of dangerous things to occur. Some of the conditions that are caused in space can be treated until the astronaut affected is no longer ill but some conditions cannot be cured or take more than a lifetime to heal. There are not any astronauts alive that have never been affected by the condition of
