Interesting details about the James Webb Space Telescope have surfaced on the Web. As it turns out, the $10 billion device has just 68GB of file storage. Depending on the task and the intensity of observations, this entire volume can be filled in just 2 hours, so the telescope is in constant communication with NASA specialists who transfer data to their servers on Earth.

The $10 billion James Webb Space Telescope has just 68 GB of memory to store scientific data.

While the drive is 68 GB, it is 3% smaller in reality, as part of the drive is used to store engineering data and telemetry. It is estimated that by the end of the life cycle (that is, in 10 years), the amount of storage for storing scientific data will decrease to 60 GB. However, in comparison with the 2 GB of memory of the Hubble telescope, this amount seems very large.

Why didn’t they make a larger drive for James Webb? There is no clear answer to this question, but there is an assumption that such parameters are provided for by the contract for the creation of the telescope, concluded back in 2003.

Due to the relatively small volume of the drive (by the way, the device does not use an SSD, but an SSR – Solid State Recorder, it is characterized by increased reliability and resistance to cosmic radiation), the telescope has to constantly be in touch with the Earth. It transmits data to NASA for two four-hour periods daily, for each of which “pumped” 28.6 GB of information. For this, a channel at a frequency of 25.9 GHz is used, the data transfer rate is 28 Mbps.

This is not the only communication channel with the telescope. There is an uplink, operating at a frequency of 2.09 GHz, used by engineers. The speed here is quite low – only 16 Kbps. And there is another downlink at a frequency of 2.27 GHz and at a speed of 40 Kbps, which transmits telemetry data, the status of the device and the parameters of its current state.

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.
