According to the state corporation Roskosmos, specialists perform final operations to prepare the rocket for the upcoming launch. After installing the media in a vertical position, service farms were brought to it. Autonomous tests of systems and assemblies of the cargo ship, the rocket itself and the launch complex are now being carried out. After that, the analysis and processing of telemetric information will begin.

The start is tentatively scheduled for July 23 at 17:26:22 Moscow time. However, the final decision will be made following the meeting of the State Commission.

The flight of the “truck” to the International Space Station (ISS) will take place in an ultra-short two-turn scheme. This means that the device will be able to reach the orbital complex in approximately three hours and twenty minutes.

Progress MS-15 will deliver to the ISS fuel and gases with a total mass of 600 kg, as well as 1520 kg of various equipment: resource equipment of onboard control and life support systems, components for experiments, sanitary and hygienic materials, garments and medicines, standard food rations and 420 liters of water in the tanks of the Rodnik system.
