Survey results that it is difficult to obtain results that are dark clouds for mining planetary explosions or just looking at investment

It is said to exist abundantly in the ground of asteroids circling near the earthRare metal(Rare metals) using the space rocket and robots are planned to bring them back to the earth, but it is obvious that in the results of the research only the mining amount below the initial expectation may be obtained It is getting.

Google's Larry Page (CEO) invests in assisting resource mining of asteroidsPlanetary ResourcesThe company and others clarify the development plan and attract attention as a method to acquire precious rare metal on the earth,Harvard · Smithsonian Astrophysics CenterMr. Martin Elvis and others have calculated that the number of asteroids that exist in the solar system and contain enough resources to meet the cost is about 10. Survey result mainly archives many papers such as physicsArXiv.org(Archive .org) has been published.

This is lower than the conventional forecast, and it seems to be asking for a review of the asteroid development plan, while Dr. Elvis also reveals that the plan is valid. Dr. Asteroid mining plan includes rare metals such as platinum, iridium and palladiumM type asteroidEstimated to be targeted. On top of that, we estimate the result that only 1% of these asteroids that go around the earth contain these metals. In addition, it is said that the target asteroid is located relatively close to the earth and needs to reach and return the mined resources.

Eric Anderson, representative of Planetary Resources, argues that the findings are "quite conservatively estimated". Anderson representative says, "Of course, M-type asteroids, of course, contain more platinum metal based on carbon-based substances as the main componentsC type asteroidWe are looking into the exploration of "the comment." On top of that, he says, "Dr. Elvis' estimate is as low as about 10, but in fact it thinks that it will cover 100 asteroids, optimistically looking at asteroids of 1000 units." .

Queen's University BelfastProfessor Alan Fitzsimmons said, "Although the trial calculation seems to be well done, I have had to touch more uncertainty," commented. That is why the composition of asteroids is still not clear. And finally, "Although the asteroid mining project seems to be a very well done plan, it will require a lot of investment.What is how to procure the expenses that will also be at national level, The problem has not been solved yet "and points out the most problem.

Regarding development of asteroids, in addition to planetary resources, newlyDeep Space IndustriesWe are trying to raise the reputation as a new business model, such as company announcement of the plan. To realize that, "Space elevator" using carbon nanotubes needs to be put to practical use, etc. There seems to be still a lot of challenges remaining.
