Roscosmos General Director Dmitry Rogozin said that the pressure drop in the transition chamber of the Zvezda module has nothing to do with the docking of MLM Nauka.

– The predicted and not at all “sharp” drop in pressure in the still problematic “Zvezda”. And it has nothing to do with MLM, – wrote the head of the state corporation on Twitter.

Later, the Telegram channel of Roskosmos reported that the pressure in the Zvezda module compartment, where the cracks were found, would be raised to 200 mm Hg. Art. during the day. The state corporation stressed that the work to increase the pressure is planned and not related to the multipurpose laboratory module “Science”. Roscosmos clarified that the pressure in MLM is normal.

Recall, as the website kp.ru wrote, the new module “Science”, which was launched from the Baikonur cosmodrome on July 21 and launched into orbit by the “Proton-M” launch vehicle, on July 29, moored to the “Zvezda” module of the Russian segment of the ISS. Earlier it was reported that about three hours after the docking, the Nauka's engines were switched on abnormally, which caused the station to turn 45 degrees.

Roscosmos will build the national space station ROSS and stop operating the ISS, since by 2024 the international station will become dangerous for astronauts. This decision was made by the Scientific and Technical Council (STC).

“Due to the aging of a significant part of the station's equipment, the further operation of the Russian segment of the ISS after 2024 creates additional risks,” the statement said.

So that the development of space infrastructure does not stop, it was proposed to create a national manned space complex in low earth orbit. It will be named ROSS – Russian Orbital Service Station.

ROSS will be built using new technologies. The station will be used for the study and development of the Moon, flights to Mars, innovative scientific and technical programs.

In “Roskosmos” spoke about the drop in pressure in “Zvezda”

During the creation of the new generation orbital station, Russia will continue to maintain the operability and safety of the ISS. By 2028, the operation of the ISS will cease. The scenario for the completion of the operation of the Russian segment is coordinated with the partners of the Russian Federation.

In the spring of this year, Deputy Prime Minister of the Russian Federation Yuri Borisov announced that Russia would create its own orbital station and withdraw from the ISS project from 2025.

According to the Futurism.com portal, citing 7news, the Tesla Megapack battery system caught fire at one of the Tesla stations in Australia on Thursday evening. The fire is not big, but the smoke emitted is very toxic. Therefore, an emergency was declared in 5 nearby cities due to air toxicity. In addition, the dependent part of the Australian power grid has suffered.

It is noted that it is not yet clear why the power unit of the station caught fire. But the fact that it caught fire during the initial battery tests suggests that there are still a lot of nuances to be sorted out before Tesla can fully return the station to working condition.

In parallel with this, the company Electrek, which specializes in testing power grids, is conducting its investigation. Its experts report that the fire began immediately after the Tesla Megapack tests were carried out. This means that we can talk about both a sudden failure and unnoticed defects that can affect all previous Tesla developments.

The Americans reacted sarcastically to the breakdown of the Russian module “Science” on the ISS. In the comments to the Fox News article, American readers argued whether Russia should be trusted in space cooperation.

“Their outdated, flawed hardware and software has been and remains a constant source of danger for this program. Today Russia has almost lost its status as a nuclear power. It makes no sense to spare their feelings in such matters. They must leave, ”wrote one of the commentators (translated here and further by Inosmi).

However, he was immediately replied that for decades the Americans had not had cargo spaceships and were forced to “ask the Russians to take them into space”: “Has it almost lost its status as a nuclear power?” Are you seriously? Typical American Arrogance. “

“In case you suddenly forget: their outdated, imperfect hardware and software supported the supply of the International Space Station and the activities of its crew during a 10-year hiatus from the last shuttle flight to the first commercial flight,” the user recalled.

American readers have also put forward several conspiracy theories. They featured a favorite product of Western propagandists – the ubiquitous “Russian hackers”. The classic “everything was rigged” was not forgotten either:

“Being on the ISS now is problematic. Russian hackers may well have caught this “software glitch”. “Everything was set up. I'm not sure who could have done this. But we should expect more similar incidents in the future. “

One of the commentators frightened his compatriots with the fact that “the guys who created this module also developed Russian nuclear weapons, missiles and nuclear reactors.”

“What product of their production will fail next? You find it funny? It's not really funny at all, ”he wrote.

The reason for the discussion was the unauthorized activation of the engines of the Nauka modules on the ISS. The reason could be the human factor, said Dmitry Rogozin, general director of Roscosmos.

The operation of the Russian segment of the ISS after 2024 “creates additional risks,” according to Roscosmos. So that the work of Russian cosmonauts does not stop, it is necessary to create a national manned space complex – the Russian Orbital Service Station (ROSS). This was stated by the chief designers of the enterprises that are part of the state corporation. The ISS itself is planned to be flooded in 2028, Roscosmos said in a statement.

On July 31, the designers discussed the state of the Russian segment of the International Space Station. The engineers noted that “due to the aging of a significant part of the equipment” of the ISS, its operation after 2024 is associated with additional risks. To continue the “continuous development of near-earth space infrastructure”, the designers proposed to create a national manned space complex in low earth orbit.

According to the chief designers, the Russian Orbital Service Station “should become an evolutionary step in the development of a program for the study and development of the Moon, flights to Mars and the implementation of innovative scientific and technical programs in space.”

The Scientific and Technical Council instructed the State Corporation Energia, together with its partners, to further analyze the state of the Russian segment of the ISS and take the necessary measures to maintain its operability “during the period of work on the creation of a new generation orbital station”.

Also, Energia was instructed to agree with the partners on the scenario for the completion of the ISS operation. The council proposed to Roscosmos to begin the technical study of the ROSS project “as part of the ISS or as an independent national station”. These works are required to be included in the Federal Space Program of Russia for 2016–2025.

On July 21, Russia sent the Nauka module to the ISS, which had been built and prepared for launch for almost 15 years.

If strains of coronavirus arise that cause a higher mortality rate among those infected, they are unlikely to become dominant, Alexei Agranovsky, a virologist, professor at Moscow State University, Doctor of Biological Sciences, told RBC.

So he commented on the findings of the report of the UK Government Emergency Advisers Group (SAGE). The report said that one of the possible scenarios for the development of coronavirus mutations suggests that the mortality of a new potential strain will be 35%.

“Such scenarios for the development of the epidemic are possible, but not required. Highly pathogenic strains, if they arise, are likely to lose in contagiousness (infectivity) and are unlikely to become dominant, ”Agranovsky said.

According to him, the conclusions from the report are “quite obvious” – it is necessary to vaccinate people, work on vaccines and try to prevent the penetration of new strains from abroad.

Larisa Popovich, director of the Institute for Health Economics at the Higher School of Economics, advised not to take seriously “such apocalyptic forecasts.” “All forecasts have a common property of not coming true. Vaccination significantly reduces mortality. And the infectivity? In the end, people will easily get sick with coronavirus and this disease will cease to be lethal due to vaccination and the formation of herd immunity, ”Popovich told RBC.

In the document of British virologists, in addition to the variant with the appearance of COVID, leading to a greater number of cases of severe course of the disease, two more scenarios were also considered:

• the emergence of options that will be resistant to drugs and vaccines against coronavirus;
• the emergence of variants of the virus with a lower level of threat, which will be transmitted faster from person to person, that is, COVID-19 will become endemic.

At the same time, the experts called the first option, which assumes the emergence of strains with higher mortality, “really possible.”

The emergence of vaccine-resistant strains was considered probable. Experts considered the latter scenario unlikely in the near future, but possible in the long term. The World Health Organization agrees that coronavirus can become endemic and cannot be completely eliminated: in December, WHO expert, Professor David Heymann expressed this point of view.

According to the WHO, all viruses, including SARS-CoV-2, change over time, but most of the changes have virtually no effect on the properties of the virus. However, mutations can affect properties of the virus, such as how quickly it spreads, the severity of the associated disease, or the effectiveness of vaccines and therapies. WHO monitors and evaluates the evolution of the virus and identifies those of concern. Now this list includes four of them. These are alpha (found in the UK), beta (South Africa), gamma (Brazil), and delta (India).

Samsung will start producing 24 GB DDR5 RAM modules in the second half of the year. This offer applies to corporate clients only.

According to the WCCF Tech edition, if you use 32 chips of this size, you can reach 768 GB in the composition. And to create such a capacitive single RAM, Samsung will produce 32-chip modules for eight-layer 8-Hi stacks. Cloud storage services are already interested in this solution. it takes the industry to the next level.

It is noted that a system with an eight-channel controller will be able to receive 12 TB of memory, but there are no processors on the market that can cope with such a volume. For comparison, the Intel Xeon Ice Lake-SP processor is shown, the capabilities of which are limited to 6 TB.
