The upcoming launch will be the sixth launch of the "Soyuz-2.1b" in 2026 and the 105th in the entire history of this rocket's operation. The "Progress MS-35" itself has a launch mass of 7280 kg.

The ship will deliver up to 2600 kg of cargo to the ISS. The pressurized compartment contains food, scientific equipment, and technology for servicing the station. In addition, the ship will bring fuel, drinking water, and gases to replenish the ISS atmosphere.
