Progress MS-25 passed vacuum tests at Baikonur

This morning, the ISS orbit was corrected to create ballistic conditions for the launch and docking of the Progress MS-25 cargo ship. And in the vacuum chamber of the installation and testing building at site 254 of the Baikonur Cosmodrome, its leak tests were just completed.

Specialists from RSC Energia and CC Yuzhny completed a full cycle of pneumatic vacuum tests of the cargo truck, which lasted from October 13. Automated control of the tightness of the compartments and on-board systems of the product in ground conditions passed without any comments.

Today, the ship was returned to its workplace at the MIK and connected to ground test equipment to continue pre-flight preparation. The launch of the Soyuz-2.1a launch vehicle with the Progress MS-25 cargo ship to the ISS is scheduled for December 2023.

Roscosmos:
The Baikonur Cosmodrome technical complex is completing pre-launch preparation of the Progress MS-25 cargo spacecraft for the flight to the International Space Station under the 86th supply mission program.

Today in the assembly and test building of pad 254 specialists of RSC Energia and Roscosmos specialized enterprises conducted an author's inspection of the Progress MS-25 cargo spacecraft and performed a set of technological operations for rolling up the head fairing. After completion of the launch readiness control set, the spacecraft as part of the space head unit was prepared for transportation to the assembly and test building of pad 31 for general assembly with the launch vehicle.

The launch of the Soyuz-2.1a launch vehicle with the Progress MS-25 spacecraft to the ISS is scheduled for December 2023. The spacecraft is to deliver to the ISS about 2,500 kg of cargo, including 515 kg of fuel in refueling tanks, 420 kg of potable water and 40 kg of compressed nitrogen, as well as 1,553 kg of resource equipment and stowage for scientific experiments, food, medical and sanitation supplies in the cargo compartment to support the work and life of the crew of the current 70th long-term expedition.

Progress MS-25 has an important mission!

It carries 2,528 kilograms of cargo to orbit - in the luggage of the truck, in addition to fuel, water and equipment, there are stowages for scientific research.

For example, for the experiment "Quail" on the ship will send a special complex "Hatchery-3" and 48 eggs of Japanese quail. In the incubator, which the astronauts will place in the module "Science", it is planned to study the embryonic development of chicks: half of the eggs will be in weightlessness, the other - in a centrifuge, simulating the Earth's gravity.

At certain stages of embryonic development (after three, seven, ten and 14 days) part of the eggs will be removed from the incubator, in a special hermetic device fixed in formaldehyde solution and then returned to Earth so that scientists can study the "frozen" embryos at different stages of formation.

The Progress will also carry equipment for the Quartz-M experiment, which the cosmonauts are to install on the Poisk module during work overboard the ISS to study and control space corrosion.
