Space mining
According to reports, recently, some scientists found that under zero gravity conditions, microorganisms can help humans extract economic elements from rocks, which means that in the future, humans may be able to "urge" microorganisms to mine ores in space. This research is also published in the latest issue of nature · communication
However, e to the zero gravity environment in space, and the extremely harsh environment on other planets except the earth, it is very difficult for human beings to reach the extraterrestrial planets to exploit space resources, and some elements are difficult to be extracted with the help of unmanned exploration and mining equipmentfortunately, through research, scientists have found that microorganisms can extract rare elements from extraterrestrial planets. On earth, experiments have proved that microorganisms can collect rare earth elements that are difficult to obtain from rocks. In the future, space experiments will be graally carried out to help human beings obtain space resources
it seems very inconceivable to exploit mineral resources with microorganisms. Scientists have found that a microorganism called Sphingomonas will leach rare earth elements from basalt through a series of chemical reactions after encountering basalt. However, in the international space station, under the condition of completely simulating zero gravity, The leaching rate of rare earth elements by Sphingomonas sp. was as high as 70%
this discovery means that it is completely feasible to exploit rare elements in space through microorganisms. It only needs to find out which microorganism is effective for which rare element
the researchers said that experiments have proved that Sphingomonas, Bacillus subtilis and cuprobacter can survive in the zero gravity environment of space. This is because microorganisms are generally specific, which allows them to survive in extreme environments. Unlike humans and other organisms, they will die if they leave the earth without any protection
at present, Sphingomonas, Bacillus subtilis and cuprobacter can help human beings extract rare elements in Mars, the moon and other environments, which means that many places that human beings can't reach for the time being, microorganisms will arrive first in the future, and help us collect the needed mineral resources and bring them back to the earth
However, there is also a question, that is, if the microorganisms on the earth are sent to different planets by human beings in the future, will they settle down in space and lead to the birth of extraterrestrial lifethe second problem is energy, not rocket fuel, but the energy problem of mining base machine operation. There is no air in outer space, and diesel and gasoline are totally useless. Although nuclear energy and solar energy can be used, the power consumed by instrial machines can not be borne by their own solar panels, and our battery technology can not reach this level, so we have to remove cables for every equipment. Mobility will be greatly constrained
secondly, the problem of automatic control is that there can not be too many staff in space. There must be many problems in both space training and space environment. Not for most people. So automation and mechanization are the best. However, the level of human automation today is not enough to build large-scale space instrial bases,
The profundity of space is both admirable and awe inspiring. The rapid development of human science and technology has promoted the pace of instry, which also gives us great convenience of science and technology. With powerful machines, it is more convenient for us to obtain and use resources from nature< the future of science and technology is immeasurable, and space mining will be an indispensable new direction for the development of human science and technology{ RRRRR}
with the continuous progress of human beings and the continuous innovation of science and technology, we can only use science and technology to make rational use of all the resources around us, and effectively and intensively use the resources where we really need them. At the same time, we advocate that we should take good care of the environment, do a good job in the positive energy work of waste recycling, and make rational use of resources
is possible. If compared with the final value of this asteroid, the investment of 5 billion yuan can be said to be insignificant. The net weight of a metal rich asteroid with a diameter of 10 meters is about 10000 tons, and the abundance of platinum is about one thousandth to one percent. If it is one percent, it is 100 tons of platinum. Calculated at 200 yuan / g, the price of 100 tons of platinum today has reached 20 billion yuan

the main target of space mining is small objects close to the earth. Most of these small objects are distributed between the orbits of Mars and Jupiter, where there is an asteroid belt called the main belt. The asteroids in the main belt will run around the earth from time to time e to the influence of gravity< human beings have discovered more than 20000 small objects, which not only contain abundant space resources, but also are many times easier to exploit than the resources of the moon and Mars. Therefore, these small objects will become the first step for us to go to space
recently, the media reported that a Lorado Mining Institute has offered the course of "space resource foundation". This is the world's first academic project dedicated to space mining research. This unique course is offered by the space resource center of Colorado Institute of mining. Since the 1990s, the Institute has been engaged in the research of "space resources and local utilization", but it has been limited to the theoretical aspect
although the college is still waiting for the approval to start in autumn 2018, in the past autumn semester, the college has completed the first pilot course. According to Professor abd Madrid, a total of 12 students study online on Tuesdays and Thursdays. In addition to college students, there are also refreshers engaged in related work, as well as students with policy analysis and economics background. In the eyes of these students, this is not only an ecational opportunity, but also a good social opportunity, because you will become the future leaders of this instry
the second pilot course of the college will start in January next year, and 24 students will be selected to participate. For the formal course next autumn, there will be 1-2 sub subjects, each of which will recruit 24 students
Professor Abdel Madrid told Red Star news that since the announcement of enrollment in July this year, more than 150 applications have been received from all over the world, including one from ChinaProfessor abd Madrid said that if you dream of joining the space instry, please send your academic credentials, GRE scores and letters of recommendation to the mailbox of the space resource center together, and you may become the first batch of professional space miners in human history
