Progress MS-15

NSSDCA/COSPAR ID: 2020-050A

Description

The Progress-MS is a uncrewed freighter based on the Progress-M-M featuring improved avionics.

The new version features the upgraded Kurs-NA rendezvous system, featuring the AO-753A antenna replaced the earlier 2AO-VKA antenna and three AKR-VKA antennas, while two older 2ASF-M-VKA antennas are retained. Kurs-NA will increase the reliability and safety during docking operations. The new SUD flight control system allows for autonomous trajectory measurements using the GLONASS (Uragan) navigation satellites. The communications system is also upgraded to use the Luch-5 data relay satellites. Also improvements were made to the micrometeoroid protection, the lighting system and the docking port. Finally, beginning with the third flight, Progress-MS can optionally carry four CubeSat deployers for a total of 24 CubeSat-units.

An automated version of Soyuz, known as Progress, was developed to carry propellant and cargo to the Salyut and Mir space stations and it will serve the same purpose for the International Space Station (ISS). Although the Mir and ISS have their own propulsion systems, generally it is the Progress vehicle which will perform periodic reboosting maneuvers to maintain the Space Station orbital altitude. The Progress is approximately the same size as the Soyuz but it has a slightly higher mass at launch of approximately 7150 kg. The Progress spacecraft docks automatically to the space station and there is also a backup remote control docking system. The Progress is composed of three modules: Cargo Module, Refueling Module, and Instrument-Service Module.

The Progress cargo module is similar in construction to the Soyuz orbital module. The cargo module carries pressurized cargo which the crew transfers into the station through the docking hatch. After the cargo module is unloaded, trash, unwanted equipment, and waste water can be loaded into the Progress for disposal when the spacecraft leaves the Station.

In place of the Soyuz descent module, the Progress has a module containing propellant tanks. The Progress is able to transfer propellant into the space station propulsion system through fluid connectors in the docking ring. The propellant in the refueling module can also be used by the thrusters on the Progress vehicle for controlling and re-boosting the Station. The Progress M has four propellant tanks (two each for fuel and oxidizer) and two water tanks. The Progress M1 will have eight propellant tanks and no water tanks. In the Progress M1, water will be delivered in separate containers carried in the cargo module.
