Today, November 27, at the Baikonur Cosmodrome, Roscosmos specialists completed the general assembly of the Soyuz-2.1a rocket with the Progress MS-25 cargo ship. The state commission then authorized the removal and installation of the rocket at the launch complex on November 28. The launch of the launch vehicle with the Progress MS-25 cargo ship is planned on December 1, at 12:25:11 Moscow time.
The Progress MS-25 will deliver 2528 kg of cargo to the ISS: 515 kg of fuel for refueling the station, 420 kg of drinking water and 40 kg of nitrogen, as well as 1553 kg of resource equipment, stowage for scientific experiments, food, etc. For example, the Incubator-3 complex and 48 Japanese quail eggs will be sent on the ship. In the incubator, which the cosmonauts will place in the Science laboratory module, it is planned to study the embryonic development of chicks: half of the eggs will be kept in zero-gravity conditions, and the other in a centrifuge simulating gravity.
Equipment for the Kvarts-M experiment will also fly on the Progress MS-25. The cosmonauts are going to install this equipment on the small research module “Poisk” during a future spacewalk. The Kvarts-M experiment is aimed at studying cosmic corrosion.
