“Major technological breakthrough”. Taiwan tests its own cubesat rocket

Published

Taiwan has test-fired a hybrid rocket it is developing independently to launch mini-satellites into orbit. We are talking about a small HTTP-3A rocket with a height of 4.8 m and a mass of 365 kg. The purpose of the experiment was to test the second stage of the propulsion system.

This is what HTTP-3A looks like

The rocket was launched from a launch pad in southern Pingtung County. It was assumed that in 8-10 minutes of flight it would reach a maximum height of 12 km and then parachute down into the sea. In this regard, the goal was not achieved: the rocket remained in the air for only two minutes, having risen by 3 km. Despite this, developers from the Advanced Rocket Research Center (ARRC) called the current launch a “major technological breakthrough” and a great success.

In addition to testing the propulsion system, the launch was also an important test of the rocket’s flight control system, ground support and parachute return system, the scientists said.

Taiwan has been implementing its space program since 1991. Until now, the island has carried out launches with the help of the United States. The HTTP-3A program aims to develop a hybrid-powered rocket capable of launching mini-satellites into orbit at least 100 km high.

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.
