Extraterrestrial organic matter was found in the samples of the asteroid Itokawa. 10 years after the samples were delivered to Earth

At the end of last year, the Japanese spacecraft Hayabusa 2 dropped a container with samples of the asteroid Ryugu to Earth.

However, this is not the first such case in space exploration. As early as 10 years ago, Hayabusa (the first generation) delivered samples of the asteroid Itokawa to Earth. And one would think that everything that is possible has already been studied there, but this is not at all the case.

The other day, an article was published, which indicated that extraterrestrial organic matter was found in the dust particles of the asteroid. Using energy dispersive X-ray spectroscopy and Raman spectroscopy, the scientists discovered organic substances, including nanocrystalline graphite and polycyclic aromatic carbon.

Scientists exclude the ingress of organic matter on the asteroid from a space probe, that is, it is precisely extraterrestrial organic matter. True, of course, this does not at all correspond to traces of extraterrestrial life – these are only organic substances.

But they allowed scientists to determine that the asteroid Itokawa has constantly evolved during its existence. Including sometime in the past, it underwent severe heating, dehydration and destruction, probably due to a collision. At the same time, after Itokawa gathered from the fragments and replenished water reserves thanks to the fall of dust and carbon-rich meteorites on it.

Billions of years ago, it was asteroids and comets, according to one of the theories, that could bring organic elements to the Earth, which became the basis for the origin of life on our planet.

Some motherboards will turn the Core i9 13900K into a power

Intel can make the Core i9-13900K even more attractive with a new auto-overclocking mode.

Some motherboards will turn the Core i9-13900K into a power consumption monster.  The power limit will increase to 350W

The source reports that some motherboards based on 700-series chipsets will allow you to activate an increased power limit. In this case, we are talking about a value of 350 watts. For comparison, Alder Lake has a maximum of 241 watts.

The values ​​of PL1 and PL2 for the new CPUs will hardly change and will amount to 125 and 253 W, respectively. But there will also be an opportunity to remove the limit, thanks to which the Core i9-13900K will be able to consume up to 350 watts. In this case, of course, the motherboard will need a powerful power supply subsystem, and the processor will need a productive CO.

CPU performance in this mode can increase by 15%, although this will depend on the tasks. Whether the Core i9-13900KS, which was previously assigned a frequency of up to 6 GHz, will be released under such conditions is now unclear.

In 10 years there will be about 70000 satellites in

About 70,000 spacecraft could be in Earth orbit by 2032. Sergey Boev, chief designer of the missile attack warning system, general director of Vympel IAC, spoke about this within the framework of the Army-2022 forum.

In 10 years, there will be about 70,000 satellites in Earth orbit.

The population density of space objects is increasing, which creates a significant threat of collisions. Now the United States, the EU countries, China and India are announcing the creation of their own megagroups of hundreds and even thousands of devices. According to our forecasts, within 10 years, the constellation of satellites in low Earth orbit can increase to 70,000 operating spacecraft“, – he said.

Boev noted that such a number of functioning satellites will be accompanied by an abundance of space debris, which will greatly complicate the situation.

All this needs to be controlled. It is necessary to improve the capabilities of the domestic space control system, increase the domestic space constellation, create small-sized spacecraft and space control tools, and need the ability to exchange information with other systems“, – said Sergey Boev.

Android 13 fixes over 150 bugs on Pixel smartphones

Recently, Google unexpectedly released the final version of the Android 13 OS, which became available for Pixel smartphones. And, it seems, the owners of such devices should install it now.

Android 13 fixes over 150 bugs on Pixel smartphones

It turned out that in Android 13, the search giant fixed a huge number of bugs that existed in Pixel smartphones. More specifically, the list includes 151 issues that Google has fixed in the update.

In particular, the Pixel 6 and 6 Pro have a much better in-display fingerprint scanner, the slowness of which many have complained about. We also fixed the issue with double-tap to wake up the screen, Always-On Display, auto-brightness, auto-rotate the screen, and more. Users of the new Pixels say that smartphones have simply become faster and more stable.

As a reminder, Android 13 is available for Google models starting with the Pixel 4 line.
