CERN launched a cubesat into space to study the effect of cosmic rays on electronics

Published

Specialists from the European Organization for Nuclear Research (CERN) have developed and launched into space the CELESTA cubesat (CERN latchup and radmon experiment student satellite), designed to study how cosmic rays and other charged particles affect the operation of microchips and other electronics.

“If the CELESTA mission is successful, then the Space RadMon device developed by us can be adapted to work inside microsatellites, which are now used to create communication probes. It will allow us to assess their condition and predict when it will be necessary to replace such satellites.”– said CERN researcher Ruben Garcia Alia.

The satellite was launched into low-Earth orbit last night by a Vega-C launch vehicle launched from the CSG launch site in French Guyana. CELESTA, which belongs to the category of microsatellites, is equipped with the only scientific instrument – the Space RadMon radiation sensor.

The instrument consists of a miniaturized version of the ionizing radiation sensors used at the Large Hadron Collider. Using this device, the scientists plan to measure the typical frequency of charged particles hitting the electronics of orbiting probes operating at an altitude of several thousand kilometers from the Earth’s surface.

In this region of near-Earth space, as physicists explain, is the so-called inner Van Allen belt. It is one of two zones in the Earth’s orbit, inside which electrons and high-energy protons accumulate, “caught” by the Earth’s magnetic field. The launch of CELESTA into this region of space will help scientists quickly assess how often charged particles get into microchips and other electronic components of satellites.

The researchers hope the data they collect will help develop systems to estimate the radiation load on orbiting probes and predict when they need to be replaced. This is especially true for fleets of communications satellites, whose electronics are most vulnerable to cosmic ray impacts due to their small size and low cost, Aliya said.

20000 mAh for 22 New Xiaomi external battery introduced

Xiaomi has released a new power bank that offers impressive capacity at a modest price.

20,000 mAh for $22.  New Xiaomi external battery introduced

The novelty costs only $ 22, but it has a capacity of 20,000 mAh. There are also three USB ports for charging other devices. True, two of them are USB-A, and only one is USB-C, capable of delivering 22.5 watts of power.

To charge the battery itself, you can use both USB-C and micro-USB present here. Separately, it is worth highlighting the presence of a low-current charging function, which is suitable when connecting smart watches, headsets and other similar devices.

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.
