Risk of Asteroid Capture and Its Needs

The asteroids were once seen as space villains. When astronomers take away a picture of a star or galaxy, there is almost no time to shadow any one asteroid. The painting does not find the perfect picture. On the other hand, asteroids may be a huge threat to the Earth's ecosystems. Due to the glory of the world, all species of dinosaurs wandering have become extinct because of the asteroid collapses on Earth.

But the time has changed now. Asteroid could be a surprising one in space research. We will get a lot of information about the evolution and evolution of the origin of our solar system, and research on the asteroid. The asteroid is likely to be a significant component of future aerospace business.

Japan's Hababusa Space Station came back with a certain amount of dust from an asteroid in 2010. NASA did a bigger plan than that. Part of this plan was to bring a large number of pebbles from asteroid through a spacecraft. But later NASA did not have enough budget in this project, due to which it has not yet seen light. But still there is good reason to detect asteroids, search and research. Nasa is working with time and manpower behind.

How to do this will be done

First NASA authorities will send a robotic spacecraft with a rocket containing chemical fuel. There will also be a very effective electric propulsion system. This system can carry the spacecraft to the appropriate place when needed. By subtracting the spacecraft on the surface of the asteroid, it will pick up a few pounds of weights through a suitable process. Robotic hand will be used to lift this pebble. Because of the low volume of the asteroid, the gravitational pull of asteroid is less. It will be difficult to do this on the surface of the asteroid which is less gravitational. But hopefully the asteroid gravity is less but not empty. It is possible to complete this task with the challenge.

Then the trunk will be placed in the orbit of the Moon. If possible, bring it to Earth. Once successfully installed in the moon orbit, scientists will be able to study experiments with a small mission easily.

Why need

In today's era, tourists such as Berlin, Paris, Cox's Bazar, and Sundarbans roam the same time that there will be a time when going from one planet to another, the Cox's Bazar-Sundarbans will be a matter of ordinary matter. Water is one of the most important components of space travel in such a distance or more distance. Although there is plenty of water in the world, it can not be taken with spacecraft during the evacuation of enough water in the solar system or on a stellar journey. There are some technical problems in it. If excessive water is consumed, weight will increase, which will prevent the spacecraft from blowing in a short time.

The same applies to fuel. If you take more fuel, you can travel much more, and if you take too much then the mass will increase, which will cause problems for the flight of early emancipation or the problem of blowing.

Asteroids can give a rough solution to this problem. Many asteroids are frozen in the asteroids. Aster's brother-in-law Comet Ice is the only ice cream. Currently, the cost of carrying water per kilo of water is 10 thousand dollars. Using water from asteroid will reduce the cost of ten times It costs 100 pounds per kilo water.

In this way, a big chunk of the grape will be brought.

Note here that the moon also has ice. But there is a lot of complex tasks taken in orbit by freeing ice from the ice, but there is ice in the moon. It is easier to do the asteroids than to collect water from the asteroid. In a study, two scientists have shown that there are many asteroids in the solar system that carry water and these are enough for long-term use. Many of them have asteroids that are easy to reach. It is not technically impossible to collect water from these asteroids and bring them to the appropriate place filled with plastic bags and convert them into water by using solar power or mechanical energy.

If sufficient technological improvements can be made, then spacecraft can be collected from asteroids. Due to limitations of weight lifting, the space stations could not take much fuel. This problem may be solved by asteroids. Analysis of asteroid ice can be found in oxygen and hydrogen. Oxygen helps burn and hydrogen can be used as a nuclear reactor. Which can be used as fuel. Although the process of bringing hydrogen nuclear reaction to humans is very challenging. Note that all the strengths of the sun are made through the nuclear reactions of hydrogen. On the other hand, the value of oxygen is not enough for humans, but it does not. Although the oxygen is available in the world, it is not easily available in space. If you do not want to live in the ocean of oxygen, the spacecraft does not have such facilities. So here asteroids or oxygen can also be useful for human beings.

Considering the more imaginative reality, it comes from creating space colonies. Hi-Tech Science Fiction. The world is going to be polluted so it is going to be out of the world - in such a situation, people may have to create a colony. And to create a colony, there will be a lot of spices. Asteroids can supply these brick stone raw materials. Thousands of years ago have been created to serve us in the future.

But the problem here is some problems. Such missions are very risky. The small auxiliaries are worth a big price. To be self-sufficient on the asteroid hunt, the world needs to be better in terms of engineering and technology. Looking forward to a day on earth as a human being, people will find such improvements in science-technology-engineering that hunting asteroids will be a stereotypical thing.
