Все грузы «Союза МС-27» перенесли на борт МКС

On Wednesday, April 9, the cosmonauts on the International Space Station began the process of unloading the Soyuz MS-27 manned spacecraft. This was reported by Roscosmos.

The 73rd long-term expedition, including Sergei Ryzhikov and Alexei Zubritsky, arrived at the International Space Station on April 8. It is worth mentioning that this is Alexei Zubritsky's first spaceflight, while Sergei Ryzhikov already has experience.

Ryzhikov's first flight was from October 19, 2016, to April 10, 2017, where he became the commander of the Soyuz MS-02 spacecraft and a flight engineer on the ISS-49/50. His second flight was on October 14, 2020, on the Soyuz MS-17 spacecraft. In April 2025, Ryzhikov flew into space again and once again became the commander.

Currently, there are a total of 5 Roscosmos cosmonauts on the ISS. In addition to unloading the Soyuz MS-27 manned spacecraft, they conducted the "Lazma", "Fagen", "Cascade", "Pegas-SP", "Quartz-M", and "Ekon-M" experiments, aimed at studying life in space:

• "Lazma" experiment — study of blood microcirculation (blood movement at the micro level) and fluorescence of biological tissues (glow of living tissues) under microgravity conditions (absence of gravity);
• "Fagen" experiment — the effect of combined solar and galactic radiation on the genetic apparatus of bacteriophages (viruses that infect bacteria) in space flight conditions;
• "Cascade" experiment — study of the processes of cultivation (growing) of cells of various species under microgravity conditions;
• "Pegas-SP" experiment — systematic observation of the upper atmosphere;
• "Quartz-M" experiment — identifying the causes and locations of corrosion on the ISS to protect against its harmful effects;
• "Ekon-M" experiment — photographing the Earth to analyze the environmental situation.

The crew members also conducted training for emergency situations and performed physical exercises in full.
