The disadvantages of space travel

What is space travel? Basically, it refers to the process of travelling in outer space. This term can also be defined as a voyage outside of Earth’s atmosphere. Humans have been fascinated by the night sky for centuries, tracking the movement of stars, comets, and planets in the open sky. In the twentieth century, the fascination with space took on an entirely new level of excitement when humans launched the first spacecraft out of Earth’s atmosphere, putting astronauts in space and on the moon. The first man to ever set foot on moon happened to be Neil Armstrong back in the late sixties. Before the landing, Neil and his partner Aldrin spent six and a half hours resting before preparing themselves for their moon walk. Ever wondered why they rested for so long? The reason to their lengthy hours of rest was because astronauts face fewer hours of regular sleep during the time they’re traveling in space. Combining that with the disruptions of our Earth’s day and night cycles that us humans have adapted within the time of our existence of Earth, result into stressed and fatigued astronauts. There are many reasons to why space travel is dangerous for our health, leaving short and long-term issues. There are many short-term issues that astronauts face during their time outside of the Earth’s atmosphere. On Earth, the cardiovascular system distributes fluids through the body, working against gravity to prevent blood from merging intro the legs and bringing blood to the brain. In microgravity, the cardiovascular system doesn’t work as hard. As fluids move from the lower to the upper body, the heart rate increases and blood pressure rises. This leads to astronauts experiencing puffy faces and headaches. This could be very dangerous for when...

...o space would need to have professional training. Astronauts now aren’t receiving enough education towards the things they’re supposed to be aware of and aren’t being taught to cope with the issues to the point when they don’t experience it as much or at all. NASA cannot continue sending astronauts into space that may experience severe symptoms that may lead into death. They need more training towards the time they are sent up, even if the prices may be high, our health should be the main priority.
