Specialists of the concern “Radio-electronic technologies”of the state corporation “Rostec” have developed an installation that can purify the air in an airplane from all known viruses, writes “Rossiyskaya Gazeta”.

The presentation of the system was held at MAKS-2021. The device was named “Tiocraft VR1000 AERO”. This is a new model of the line of air purifiers, which are serially produced by the Ramenskoye Instrument-Making Plant.

It is noted that the device has an efficiency of over 99.9%. It cleanses the air from all known viruses, including the coronavirus. According to experts, the minimum particle size that Thiocraft is able to neutralize is 10 nanometers, while, for example, the size of the SARS-CoV-2 virus virion is from 50 to 200 nanometers.

The device can be used both during the pre-flight preparation of the aircraft, and directly during the flight.

It is emphasized that the technology has been confirmed by appropriate tests. “Tiokraft” has small dimensions and has the mobility of the installation.

Earlier it was reported that employees of the Center for Photonics and Quantum Materials of the Skolkovo Institute of Science and Technology have developed a nanomembrane that can kill microorganisms and viruses. It was noted that the development is planned to be used in filters of air purifiers and in air conditioners in medical institutions, airplanes, public transport and in production.

NASA expects that it will be able to support the work of the ISS at least until 2028, reports TASS.

This was reported by the representative of the American department, Stephanie Schirholz, during a conversation with the agency’s correspondents.

Earlier, Roscosmos said that the operation of the Russian segment of the ISS after 2024 creates additional risks due to the aging of a significant part of its equipment. In this regard, it was proposed to create a Russian manned space complex in low Earth orbit.

Commenting on this message, Schirholz said that NASA expects that they will be able to support the work of the ISS at least until 2028 or longer. At the same time, the agency continues to update the technical analysis of the service life of the space station.

According to the representative of the department, the goal of NASA is a continuous presence in low-Earth orbit in order to be able to move from the ISS to another platform that will allow this work to continue.

Earlier, the head of Roscosmos, Dmitry Rogozin, denied reports of readiness to extend the operation of the International Space Station until 2030. He also said that Russia’s withdrawal from the ISS project depends on the US decisions on sanctions against the RCC “Progress” and TsNIIMash.

The Scientific and Technical Council of Roscosmos recommended that work on the creation of a technical project for a new orbital station be included in the Federal Space Program – 2025.

According to the press service of Roscosmos, the recommendation was given in order to eliminate the risks associated with the technical condition of the Russian segment of the ISS, and the planned completion of its operation by 2028.

It is noted that RSC Energia will analyze the state of the Russian segment of the station and take measures to maintain its operability during the creation of a new one. In addition, a scenario for the completion of the ISS operation, agreed with partners, will be developed.

In the spring of this year, it was reported that the state of the International Space Station leaves much to be desired, so the Russian Federation can focus on creating its own orbital station. The Energy Corporation should ensure the readiness of the first basic module for the new station in 2025, its preliminary design will begin before the end of this summer.

Earlier on Saturday, July 31, Russian cosmonauts reported a drop in pressure in the ISS module due to an air leak. The pressure in the transition chamber of the module “Star”, where the cracks were found, fell to 154 mm of mercury. Roscosmos promised that it will be raised to normal values within a day.
