Astronauts are some of the best scientists in the world, but that doesn’t take away the fact that they work in a high-risk environment full of unknown mysteries. In such an environment, a slight mistake would be the difference between life and death.
When in space, astronauts tend to stay in the orbit for around four to six months. It’s believed that the period is enough for them to make scientific experiments on their bodies and the changes that might be caused by being in a microgravity environment. The problem is, astronauts stand a risk of being affected by back mutations, brain degeneration and muscle atrophy. Imagine an environment where your own tears can quickly turn into a pool of water enough to drown you. Since the beginning of America and Russia space programs, about 430 astronauts have traveled to space and 34 have died! That’s 7.5% mortality rate, which is astonishingly higher than many professions on this list.
