As a result of the flight control group operational meeting at the TsNIIMash Mission Control Center (part of Roscosmos), the specialists decided to adjust the plans to undock and deorbit the Pirs module.

The decision came based on the telemetry data and the need to build optimal orbit conditions. The operations are currently scheduled for Monday 26 July, 2021.

On Saturday, Roscosmos cosmonauts Oleg Novitskiy and Pyotr Dubrov closed the transfer hatches between the Pirs module and the Russian segment of the International Space Station, and checked them for pressure integrity. The physical separation is preliminary scheduled at 10:56 UTC on July 26, the non-combustible structural elements of the module and the ship are to drop in the Pacific Ocean at 14:51 UTC of the same day.

The Pirs docking module is now docked to the nadir port of the Zvezda Service Module of the Russian segment of the International Space Station. It is planned that after undocking it will be replaced by the Nauka Multipurpose Laboratory Module, which was launched from the Baikonur Cosmodrome on Wednesday and is currently in autonomous flight.

Prior to that, the Aist-2D small remote sensing spacecraft, developed at the Progress Rocket and Space Center (Samara, part of Roscosmos), photographed the International Space Station. RSC Progress is the operator of the Aist-2D satellite, providing control, reception, processing and distribution of the received information of remote sensing of the Earth.

  The presentation of the Ya-130M aircraft took place at the international military-technical forum "Army-2024", which was held from August 12 to 14, 2024 at the Patriot Convention and Exhibition Center. It should be noted right away that this is not just the modernization of the Yak-130 aircraft, but the transformation of a combat training aircraft into a full-fledged light combat aircraft. In the information field, this event was marked by a number of brief reports from federal news agencies. But the project, like the Yak-130 aircraft with its unique flight characteristics, deserves a more detailed review, which we decided to do.
