Earth is the reason we are able to live so happily today that this is the reason why there is no atmosphere like our earth in this universe so we are lucky to find a planet like earth if anything happens to this special planet in the future how should all people live, that is why scientists are doing research to overcome this problem. Best options Moon and Marks We have to go to the original means first we have to learn how to live in space so today I am going to tell you how life is in space Living in space is not a normal thing it is very risky and also very interesting why on earth we have to go to space You may think that it is good but that is wrong thing Columbus how he was able to discover America by exploding new places how Vasco da Gama was able to discover India by exploding new places so if we also explode space we can learn many new things without exploring space. If there were no satellites today, we would not have had satellites if there were no satellites there would have been no mobiles there would have been no communication between people between countries, that is why the space agency was established and research is being done. So you have to know that the American Space Agency and the Russian Space Agency have done it together in space but it was accompanied by technical knowledge that we don’t need so now there is a space station. Now people have to research in this space station, how is the atmosphere in space how does that atmosphere affect our human body.
How plants grow in space what are the effects of being in space for a long time how to make electricity in space research should be done on such things. So to do this kind of research first of all it needs people. Also people should be able to live there so they have to live in space which means there are three stages in total how to go into the first space how to live in the second space. Third, before returning to earth I will tell you about the first stage. Those who work are not gods. They are human beings like us. We can also work in the space station. First you need a degree in just engineering, mathematics, or physical science. Should have work experience or should have flown a thousand hours airplane Sir health should be good. If you have these three qualifications you can also do research so space agencies like NASA select those with similar qualifications and give them training in three subjects for two years. First how to control the space track. They are taught and given training in these three subjects. After this training is completed they are sent to the International Space Station in any space craft. So two space crafts are used to send people into space. If they travel in space they are called astronauts. Their only profession is to travel in space. Now this vehicle has to be connected to the space station in the sky this connection is called docking, only then can you step into the space station in the vehicle so it is clear how it is connected to the space station there are the tiles in the middle.
There is the main engine in the upper part of the rocket, that is near the nose there is the Soyuz capsule and the astronauts stay there. The capsule has a covering around it so it cannot be seen from the outside which is an important component in a rocket These help to give more energy to the rocket and after going up hundreds of kilometers they break away from the rocket and fall into the ocean. Because until there there is friction in the air the rocket uses more energy to overcome that friction after that the rocket goes in a curve shape the orbit radius increases a little, then the main rocket engine separates and the Soyaz capsule comes out. There are play astronauts in this capsule are A small capsule with their power docks to the International Stay Station A rocket has a reason to go in a drought But how much gravity does it need more feel to move vertically then it runs out before it reaches the destination point It takes less on the rocket Also the high gravity rockets around the earth without fuel Earth rotates towards east so rockets are also launched towards east. Maximum rocket launch stations are next to the sea because if there is any technical problem and the rocket explodes then all the parts will fall into the sea then people will not be harmed. Doubt you may get the same technology that is where mathematics is very useful. It is calculated very actively and the rocket is launched. Totally four times the indicators tell how much it takes 6 hours to reach back to the space station.
If there is a small mistake in the calculation, sometimes it takes two days to dock. Inside the capsule there are astronauts and food supplies. Once in six months this Soyuz rocket is launched and the astronauts are sent to the station and you may think that they will not come. There is friction due to the air on top so the sound is heard. In space, there is no air so there is no friction so the people inside do not know that they are going that fast. There may be a doubt as to why the space station did not fall on the earth the reason is that the orbital velocity is at an altitude of 445 kilometers and it revolves around the earth with a speed of 2800 kilometers. Gravity does not work above the space station this is called escape velocity then how much space station escapes from the gravitational force then how much space station does not rotate why does it rotate around the earth, the reason is that the gravity of the earth does not allow it to go down it also prevents it from going straight. Earth makes any object rotate around itself. Many people think that gravity becomes zero when it goes up but it does not become zero except as it increases. Wrong Exams. Any object is in motion in space so long as it is not disturbed it will continue to rotate. I will tell you the best example if there is no air inside the earth, then if you throw a ball horizontally it will not fall down and it will continue to go as long as you do not disturb the ball. But because there is air inside the earth due to friction the speed of the ball decreases after it travels some distance and it falls down.
So even in space earth gravity works in the same way. Another best example is the moon. It takes 92 minutes for this space station to rotate. So in one day this space station will go around the earth 16 times which means the sun will be seen rising and setting 16 times every day. This minute you can also know where this second space station is by taking the cameras attached to the station and the earth video also shows it. Gravity is very low in the face station. Water is in small packets for cleaning. Water is very expensive here so urine is also recycled and used. Gravity is less here so your hair floats up next whatever you have to eat it will also be in the packets. There is no gravity and there may be a doubt as to how the food will go inside the stomach. When the food goes inside our body takes care of all the other work so even if you eat with your head down it goes inside the stomach. It is very narrow inside the space station. There is only a small place to sleep. Since you do not lift heavy weights during the day all your bones will be weak so you should exercise regularly. You should attach yourself to redmill and run. Otherwise it will be difficult. Can not see rain Normally astronauts stay in station for six months then come back to earth so how do they come back to earth after that they slow down a little it goes around earth for a while it enters that is capsule splits into three parts astronauts stay in the part in the cylinder shops in the middle the separated parts are due to fiction when they enter the atmosphere burn out because it has a coating that can withstand high temperature
