China is developing a lunar gravity simulator

Published

The United States and its international partners are currently in full preparation to be able to return to the Moon by the end of the decade. But another country is also actively working to allow its astronauts to set foot on lunar soil, China. In addition to the construction of rockets capable of taking passengers to the Moon, we now know that the country is developing a lunar gravity simulator which will allow preparation tests to be carried out.

According to what was reported by the South China Morning Post, Chinese researchers are working on a device that can produce moon-like gravity. It is actually a vacuum enclosure using a powerful magnetic field capable of recreating a low gravity environment.

According to Li Ruilin, a geotechnical engineer at the China University of Mining and Technology, once the device is ready, it can “make gravity disappear for as long as you want”. The manufacture of the device in question could be completed within a few months.

Not for astronauts

While being able to move around in a low-gravity environment without leaving Earth is something we would all like to try, the device being developed by Chinese scientists is not intended for humans. Indeed, the enclosure will have a diameter of 60 cm, which is far from being enough for an astronaut dressed in his space suit.

The device can, however, be used to test equipment and tools that could be used on the Moon. Researchers will be able to see how these objects will react to the low gravity environment of our satellite.

According to Li Ruilin, some experiments that will take place in the enclosure will take a few seconds, such as the impact tests. But others, like creep tests, can take several days.

The origin of the invention

According to the information, the simulator is partially inspired by a study carried out by Russian physicist Andrew Geim. This physicist had succeeded in making a frog float using a magnet. This experience also allowed Geim to receive the Ig Nobel Prize in Physics. It is a satirical prize given to reward unusual scientific research.

In any case, being able to test the material in advance has many advantages in the field of space. This will make it possible, among other things, to detect certain faults which could cause problems when the time comes.

The Tesla Cybertruck electric pickup truck will have a “little brother” in miniature form

While Elon Musk and Tesla continue to push back the start of production of the Cybertruck electric pickup truck to ever later dates, information has appeared on the network about the possible release of another version of this car.

Initially, the rather well-known Indian analyst Trip Chowdhry from Global Equities Research, who specializes, among other things, in Tesla, shared the information.

According to the source, Tesla will present two versions of the Cybertruck at a special event in March 2022.

Moreover, Chaudhry notes that both versions will receive “significant changes” compared to the Cybertruck originally shown. Chaudhry did not go into details of the changes, but noted that the second version of the Cybertruck will be about 15-20 percent smaller than the first. The bodies of both cars will reportedly be built by the same Texas-based Steel Dynamics company, which operates about 100 miles from Tesla’s Texas plant.

Chaudhry expects to hear the first official news on the matter on January 26, when Tesla will report earnings to investors.

Recall that in November 2019, Elon Musk himself said that in the long run it makes sense to add a more miniature Cybertruck to the lineup. Since then, however, he has not further developed the idea publicly.

WhatsApp will soon be able to draw with different strokes

The Meta (former Facebook) team of the popular WhatsApp messenger is working on a new interesting feature for users.

WhatsApp will soon be able to draw with different strokes

In the latest beta version of WhatsApp for Android, there are hints of new drawing tools. As the thematic resource WABetaInfo drew attention to, two new pencils have been added to the built-in WhatsApp image editor in addition to the existing pencil. The pencil icons indicate that the new pencils will allow you to draw thicker lines on images or videos.

WhatsApp will soon be able to draw with different strokes

WhatsApp currently allows you to change the color of the pencil, but there is no way to increase or decrease the thickness of the stroke. In addition, WhatsApp has begun work on a blur tool. This should make it easier to share screenshots and photos by allowing you to “blur” the areas you need before sending.

It is not yet clear when the new tools will become publicly available in the stable versions of WhatsApp.

Taiwan strives to become self-sufficient in semiconductor equipment

Published

on

Taiwan President Tsai Ing-Wen told local media that she believes Taiwan can become self-sufficient when it comes to semiconductor equipment, although it obviously won’t happen overnight. The source said the issue is largely being considered in connection with the pandemic, which disrupted production and delivery systems, affecting most of Taiwan’s industries.

Taiwan strives to become self-sufficient in semiconductor equipment

In 2021, Taiwanese semiconductor companies invested about $363 billion, of which 70% was in equipment, with about $21.8 billion of that money directed towards imported equipment, the president said. It also shows that local semiconductor manufacturers have a lot of work to do, especially if they intend to catch up with their international competitors. The local semiconductor equipment industry grew by 28.7% in 2021, although it was still relatively small at $4.2 billion. Tsai Ing-Wen expressed her full confidence that Taiwan has the ability to produce all the semiconductor equipment needed by the local industry.
