According to NASA, the Webb telescope would have enough fuel for about 20 years

That’s it, the James Webb Space Telescope is currently fully deployed. The solar shield and the mirrors are all in their place. All that remains for the space observatory is to reach its final position and calibrate its instruments. But the good news does not end there as NASA has just announced that the amount of fuel on board Webb could allow it to operate for about 20 years.

This news was announced by the scientists in charge of the telescope during a press conference on Saturday, January 8. The conference was organized to mark an important milestone which is the successful deployment.

According to Bill Ochs, Webb’s project manager, the limiting factor at launch is the amount of fuel.

An excellent performance from Ariane 5

During the conference, Ochs did not forget to mention the “super-precise” launch carried out by Arianespace’s Ariane 5 heavy launcher on December 25. He indicated that thanks to the efficiency and precision of the launch performed by Ariane 5, as well as the equally excellent performance of the team during course corrections, they have a fuel margin of around 10 years.

In total, Webb thus has on board a quantity of fuel corresponding to approximately 20 years. However, Ochs added that it still had to be determined.

One last operation to perform

What still needs to be determined is how much fuel will remain after the next lane correction. This event will take place in about 2 weeks and will allow the telescope to reach its final destination.

It is estimated that Webb will arrive at his “place of insertion” by January 23. It will use its thrusters to be able to reach its position which will be at Point de Lagrange L2 1.5 million kilometers from Earth.

This Lagrange point is a position where the forces of gravity of the Sun, Earth and Moon are balanced. This will allow Webb to remain stable while using a minimum amount of fuel.

Apple Declares 2013 and 2014 iMacs Obsolete and Watch Series

Apple has added three models of iMacs to its list of obsolete products: a 21.5-inch screen from 2013, a 21.5-inch screen from 2014, and a 27-inch Retina 5K screen also from 2014.

Apple typically deprecates products seven years after they were released, so it’s no surprise that the 2013 and 2014 iMacs are on the list.

As for smart watches Apple Watch Series 2, they are recognized as “vintage”. This category usually includes devices that have been released for five years. There may be problems with the official repair of the aforementioned iMacs.

There are almost 1 billion 5G users Ericsson report shows

According to a report by Ericsson cited by The Verge, by the end of this year, the number of 5G subscribers in the world will reach 1 billion.

Of course, this is far from the performance of 4G networks, which are now used by about 5 billion people, but still this is a fairly significant part of the market.

There are almost 1 billion 5G users. Ericsson report shows that operators often ask for more money for such tariffs.

Of course, 5G adoption is far from uneven. In North America, about 35% of subscribers will use 5G networks by the end of this year.

At the same time, the report indicates that operators often ask for more money for the higher speeds offered by new networks. Dividing into corresponding tariffs is popular among operators in Western Europe, but overall, 25% of operators worldwide charge extra for 5G. And the average markup is 40%.

Ericsson believes that, unfortunately, this trend will continue for several more years, as operators need to compensate for the costs of developing a new network.

Is Apple Helping the Chinese Government Fight Protests? The company cut the AirDrop function in the Middle Kingdom

Is Apple Helping the Chinese Government Fight Protests The company

The history of protests in China is overgrown with new interesting details related to IT companies.

Is Apple Helping the Chinese Government Fight Protests?  The company cut the AirDrop function in the Middle Kingdom

Just weeks before the protests began, Apple reportedly made a major change to how AirDrop works, and only in China. After updating to iOS 16.1.1, AirDrop in the mode of receiving messages from everyone became possible only for 10 minutes, after which AirDrop simply turns off. In normal mode, AirDrop has no time limit, as there is none now and all over the world outside of China.

The fact is that AirDrop is one of the ways protesters communicate, and not only in China. AirDrop works locally in smartphone-to-smartphone mode, without relying on external networks, so it cannot simply be blocked or read data. But in this case, for some reason, Apple decided to seriously change the function, although it did not turn it off completely.

The CNBC resource also notes that the corresponding update was released a month after Chinese President Xi Jinping was re-elected for a third term.

Recall that Huawei smartphones have been noticed that they automatically delete videos that depict events related to protests in China.
