China does not play games in an effort to explore space. After Changing Land 4 on the dark side of the Moon and planning for an artificial three month orbit, now, as stated by state media Daily Science and Technology (h / t Nature), they want to build solar power stations in space.

The station's station is intended to be the first in the world at a height of 36,000 km from the Earth's surface.

The rationale for the scheme was introduced by communication experts Pang Zhihao, head of China Space Space Corporation's science, to have sustainable and environmentally friendly energy sources.

Pang explained that solar energy harvested in space would be 99 percent more than what was received on Earth, because there was no harassment in the atmosphere, such as weather, seasons or the arrival of the night.

They intend to launch the vehicle to the atmosphere between 2021 and 2025. In 2030, they intend to increase the capacity of the power to megawat levels and to gigawatt levels by 2050 .

How do you send the energy collected to the Earth? In principle, Pang said, the solar collector in space converts energy into electricity. Electric power is then transformed into other devices into microwaves (microwave) or laser.

The microwaves or lasers will then be transferred to the acceptable system on the Earth, converted to electricity, and distributed to those that are required.

In principle, according to Pang, this is not something difficult. In addition, solar energy generation, microscopy transformation and other associated space technologies have moved on. It only developed.

The idea of ​​making solar power stations in space, quotations Nature, in fact he has begun to be studied by experts in the United States and Japan for a decade ago.

But they were faced with the problem of costs and ways of an industrial-scale flight station. Especially because the total weight can reach 1,000 tonnes. In comparison, the pressure of the International Space Station (ISS) is only about 400 tonnes.

To overcome this problem, Chinese researchers are studying the possibility of building the station in space using robotic technology and 3D printing.

In addition, according to Pang, they also study the effects of radiation microwave on ecology on Earth, the atmosphere, and the organisms in it. This is related to the long-term operational safety of the station.

According to Engadget, The China scheme is very likely to come true. In Japan, for example, in 2015, there was a solution to send power back to the Earth effectively using a wireless transmission.

In addition, in early 2018, scientists from the California Institute of Technology (Caltech) announced that they had created a prototype that could collect and transfer solar energy from space using light tiles.

Return to the Moon

In addition, back Daily Mail (18/2), officials from the Chinese Space Agency also said they would return to the Lleuad mission later this year using Chang-e-5.

After Changing e-5 came home carrying rocks from the face of the Moon, three consecutive rides were prepared.

Chang e-6 will be the first mission to explore the Earth's southern satellite. Although Chang's e-7 followed later to study the surface, composition, and space of the space in a comprehensive mission. Finally, Chang-e-8 will focus on technical surface analysis.

The Chinese National Space Agency (CNSA) said they also planned to go to Mars in 2020. If realized, they will pass the US, Russia and a large number of private companies wishing to pull their rocks on the Planet Coch.
