For the benefit of Science and Technological Development, People found a way to travel in space in the 19th century. Scientists found that if it is possible to throw something with more than gravitational force, this object can reach beyond the Earth’s atmosphere. But at that time, there needed to be more facilities to gain this enormous force. But in between the first and second World Wars, people succeeded in inventing powerful rocket engines in trying to find a more effective way to defeat the enemy. That technology gives the ability to human to travel into spaces.
History of Travelling into the Space
In continuation, Sputnik-1 is the first satellite to travel into space. The Soviet Union made this history in 1957. After that Soviet Union made another history by sending a human named Yuri Gagarin into space through a spaceship, Vostok-1, on 12th October 1961. After reaching space, Vostok-1 travelled 41000 kilometres in a circular path around the Earth. After spending 108 minutes in space, Gagarin returned safely to Earth. After two years of Gagarin, Valentina Tereshkova was the first female to travel to space, leaving the Earth’s atmosphere through the spaceship, Vostok-6. Vostok-6 rounded the Earth 48 times. After spending 71 hours, Valentina came back to Earth safely. After that, in recent 50 years, 563 people have gained the blessedness to travel to space as successorship of Gagarin and Valentina.
After listening to all of this, it would be thought that people have overmatched the space. Also, it would be thought that after wearing a white spacesuit, all problems will be vanished, as shown in a Sci-fi movie in Hollywood. But the reality is soo harsh. In fact, beyond a specific limit of Earth’s atmosphere, the whole universe is heartbreaking. Either there is no oxygen essential for human existence or the essential gravitational force. Even without the air pressure we are used to at the surface, and our blood will begin to vaporize when unprotected.
What kind of problems can you get into in space?
While walking in space, there could be a dangerous situation if there is any damage in the suit because this suit controls the essential part as the supply of oxygen and the atmospheric pressure in the space. It is impossible to remain conscious for more than 15 or 20 seconds if there is a disruption in the oxygen supply. If there is a problem with atmospheric pressure, the gases in the human body will start to expand. As a result, the human body will Swellheadedness as more than double sized.
But have you ever wondered what will happen if you suddenly lose your way or get lost during space travel while wearing this suit?
As part of the primary safety measure against this danger, astronauts work in pairs in space. At the same time, they are tied to each other by steel ropes, similar to spaceships.
A jetpack was added to the suit, eliminating the risk of the astronauts becoming lost if the rope breaks. Using the Jetpack, astronauts can return to the spacecraft from a short distance. But if the jetpack doesn’t work, the astronaut has to be floated based on the accompanying oxygen. Unfortunately, after about seven and a half hours, when that oxygen runs out, the astronaut must die from lack of oxygen. Then the body will soon turn into a mummy in the extremely high temperature of the sun.
On the other hand, if there is a disturbance in the suit or oxygen supply, the water vapour in the human body will evaporate, and the human body will immediately turn into a mummy.
But even after a long list of hazardous stuff, there is no death occurrence of humans in space.
However, many spacecraft crashes into Earth’s atmosphere. However, no astronaut has ever been lost in space due to caution or for any other reason.
