A team of researchers from Shandong University in east China has studied a geological anomaly in the Moon’s largest, deepest and oldest crater, the South Pole-Aitken Basin, which lies on the far side of Earth’s natural satellite.

Chinese scientists have studied the largest crater of the moon and found something interesting

Chinese scientists have determined that the mantle at the bottom of the crater contains an unusually large amount of plagioclases (a group of rock-forming minerals of the isomorphic series), which are usually found in the surface layer – the lunar crust. Experts do not exclude that after the formation of the basin in this area there was a significant collision with the Moon of a certain cosmic body.

The data analyzed by PRC specialists was obtained by the Chang’e-4 station, launched on December 8, 2018. She worked on the Moon for 44 lunar days (each lasts approximately 14.5 Earth days) and is now in sleep mode, since the period of the next dark time of the day has come (night on the Earth’s natural satellite also lasts two weeks).

The South Pole-Aitken Basin is the largest known crater on the Moon. Located on the south side. It has a size of 2400 x 2050 km, which makes it one of the largest craters in the entire solar system. It is the deepest and oldest known impact structure on the Moon. The depth of the basin reaches 8 km, and the total height interval is 16.1 km.

‘Best semiconductor material ever discovered’ found US professor suspected of spying for China

Best semiconductor material ever discovered found US professor suspected of

A team of researchers at the world-renowned Massachusetts Institute of Technology (MIT) has found that cubic boron arsenide has better properties than silicon for making microchips, calling it “the best semiconductor material ever discovered.” Notably, the team that made the discovery also included a Chinese-born scientist previously suspected of spying for China.

According to the study, cubic boron arsenide is ten times more efficient as a heat conductor than silicon. It is also the best conductor of both electrons and electron holes – this is especially important for the properties of a semiconductor. Materials such as boron arsenide could change the rules of the game in industry.

The investigation team included Gan Chen, a former head of engineering at MIT, who was under investigation for a year on suspicion of espionage, after which the US Department of Justice dropped the charges for lack of evidence.

It may well be decades before boron arsenide-based chips become commercially available—if the technology is ever found usable. Nevertheless, it is expected that the material can be used to produce better, faster and more compact chips than today.

Gan Chen was arrested in January 2021. He was accused of hiding ties to the Chinese authorities in applications for a grant from the US Department of Energy. The scientific community, including scientists from the Massachusetts Institute of Technology, criticized the arrest and wrote an open letter. Under President Joe Biden, the Justice Department dropped all charges.

Scientists emphasize that such a “witch hunt” discourages researchers, especially from China, from moving to the United States, which is why the United States cannot use its intellectual potential.

“The sale of SIM cards is really becoming more expensive and meaningless,” MTS will reduce sales of SIM cards and the number of communication stores

The sale of SIM cards is really becoming more

MTS President Vyacheslav Nikolaev said that the company plans to move towards reducing sales of SIM-cards, as well as reducing their points of sale.

It seems to me that now, when the cost of SIM cards has increased by an order of magnitude, it’s time to heal this market. Therefore, from the point of view of sales of SIM cards, it seems to me that the sales volume can now be reduced, especially since for us, ecosystem effects provide very serious advantages in reducing the outflow – this also allows us to take sales more calmly.

“The sale of SIM cards is really becoming more expensive and meaningless,” MTS will reduce sales of SIM cards and the number of communication stores

Nikolaev noted that an increasing number of customers are also moving online, which also allows, in terms of telecom, to reduce the number of their own points of sale.

From the point of view of telecom, it seems to me that this is a very timely issue, and perhaps the right actions will be taken by the entire market. At least we will go in this direction. We hope that colleagues will not be far behind, because selling SIM cards is indeed becoming more expensive and pointless.

As we have already reported, MTS may sell its tower business.

The SpaceX Starship interplanetary spacecraft has not yet made a

One of Asia’s largest telecoms and pay-TV operators, Japanese company Sky Perfect JSat, has announced that it plans to use the SpaceX Starship interplanetary spacecraft to launch its Superbird-9 telecommunications satellite into geosynchronous orbit in 2024. The details of the deal were not disclosed.

The SpaceX Starship interplanetary spacecraft has not yet made a single orbital flight, but the Japanese have already announced the launch of their telecommunications satellite on it

The situation is noteworthy in that Starship has not yet made a single orbital flight: Elon Musk promises to launch Starship on a test flight into orbit almost every month for about a year, but it is delayed each time. However, there is no contradiction that an interstellar spacecraft to launch a payload into orbit: in concept, Starship should replace all of SpaceX’s current rockets, including the workhorse Falcon 9, which goes into space every week.
