Ionosphere-M satellites have recorded an increase in plasma density in the atmosphere

The Russian Ionosphere-M satellites No. 1 and No. 2, launched into orbit in November 2024, recorded unusual changes in the upper atmosphere during the first six months of operation. Mikhail Mogilevsky, head of the Laboratory of the Space Plasma Physics Department at the Space Research Institute of the Russian Academy of Sciences, told Izvestia about this on July 25.

"In particular, their measurements showed an extremely high density of ionospheric plasma. This is confirmed by other measurements on spacecraft and on Earth," he said.

He explained that an increase in plasma density may be one of the reasons for the accelerated deceleration of the International Space Station (ISS) and other satellites. This requires more frequent adjustments to their orbits, and also leads to faster wear of the equipment.

The scientist added that the observed phenomena may be related to solar activity within cycles with a large time scale, which have not yet received sufficient scientific attention. Satellites were probably able to record these processes.

Ionosphere-M satellites No. 3 and No. 4, which will be launched on Friday, July 25, will complement the orbital constellation. This will help to verify the conclusions reached and develop the research results.

Earlier, on July 17, Russian Foreign Ministry spokeswoman Maria Zakharova announced at a briefing that Russia was ready to cooperate in space with all countries. According to her, Moscow continues the traditions of Russian cosmonautics and is open to constructive interaction with all participants in space activities. Zakharova stressed that the accumulated experience makes it possible to develop mutually beneficial and equal cooperation without closed alliances and unilateral standards.
