Researchers advocate the idea of creating a living space on an asteroid near the earth
Migration to the moon and Mars is one of the dreams that mankind has had for a long time, but a new paper has been submitted that it is possible to migrate to an 'asteroid'. According to the author, it will cost only 4.1 billion dollars (about 590 billion yen) and will be completed in 12 years.

David Jensen, who used to work as an engineer at Rockwell Collins, a major aircraft and defense company, wrote a paper advocating the ``Asteroid Migration Plan'' and asked ``where'' and ``what'' about migration destinations and migration methods. It is divided into three points of “how” and explained.
First of all, regarding 'where', Mr. Jensen points out that it is necessary to consider 'what the asteroid is made of', 'how close it is to the earth', and 'how big it is'. Based on these factors, Mr. Jensen suggested the asteroid ' Atira ' as a candidate.
Atira is an asteroid that orbits the Earth's orbit and has a diameter of about 4.8 km. Accompanied by a small asteroid with a diameter of 1 km, it orbits the Sun at a distance of about 0.5 to 0.9 AU in about 233 days. At the point of Attila's closest approach to Earth, the distance between the two bodies (minimum intersection distance) is about 30.8 million km, which is about 80 times the distance from Earth to the Moon.
In order for people to live on these asteroids, a living space suitable for people to live is required. There are various shapes of proposed living space, such as a dumbbell shape, a sphere, a cylinder, or even a torus (doughnut-shaped shape). It has been taken.
According to Jensen, one of the most important considerations in determining the shape of a living space is the use of 'centripetal force,' or artificial gravity. However, in order to exert centripetal force, it is necessary to rotate the living space. From this point of view, Mr. Jensen thinks that 'Taurus' is the best, and he is considering rotating Attila itself.
In order to build such a living space, it is necessary to secure labor and resources accordingly. In this regard, Mr. Jensen proposes using 'robots' as a labor force and using rocks on asteroids as materials.
A base, four spider robots, and a 'seed' capsule with enough advanced electronics to build 3,000 spider robots on site, together weighing 8.6 tons, according to Jensen. It must be sent to Attila. If you have these basic supplies, you don't need additional supplies from the earth.
At least in theory, 1 billion square meters of living space could be built for $4.1 billion. According to Jensen, the construction project will be completed in as little as 12 years. However, it takes more time to build the environment, such as filling the living quarters with air and water and adjusting the temperature. Still, it is a relatively short schedule for such a project, and Mr. Jensen shows the prospect that 'if completed, it can support a population of more than 700,000 people.'
