Progress MS-23 (Russian: Прогресс МC-23), Russian production No.453, identified by NASAasProgress 84P, was a Progress spaceflight launched by Roscosmos to resupply the International Space Station (ISS). It was the 176th flight of a Progress spacecraft.

History[edit]

The Progress-MS is an uncrewed freighter based on the Progress-M featuring improved avionics. This improved variant first launched on 21 December 2015. It has the following improvements:^[1][2][3][4]

• New external compartment that enables it to deploy satellites. Each compartment can hold up to four launch containers. First time installed on Progress MS-03.
• Enhanced redundancy thanks to the addition of a backup system of electrical motors for the docking and sealing mechanism.
• Improved Micrometeoroid (MMOD) protection with additional panels in the cargo compartment.
• Luch Russian relay satellites link capabilities enable telemetry and control even when not in direct view of ground radio stations.
• GNSS autonomous navigation enables real time determination of the status vector and orbital parameters dispensing with the need of ground station orbit determination.
• Real time relative navigation thanks to direct radio data exchange capabilities with the space station.
• New digital radio that enables enhanced TV camera view for the docking operations.
• Unified Command Telemetry System (UCTS) replaces previous Ukrainian Chezara Kvant-V as the Progress spacecraft's on-board radio and antenna/feeder system.
• Replacement of the Kurs A with Kurs NA digital system.

Launch[edit]

ASoyuz-2.1a with Progress MS-23 to the International Space Station from Baikonur Site 31 launched on 24 May 2023 at 12:56 UTC^{[5][6][7][8][9]} supporting Expedition 69 and Expedition 70 missions aboard the ISS. It docked the same day.^[9]

Cargo[edit]

The MS-23 cargo capacity is approximately 2,500 kg (5,500 lb) as follows:^[9][10]

• Dry cargo: 1,290 kg (2,840 lb)
• Fuel: 499 kg (1,100 lb)–600 kg (1,300 lb)
• Oxygen: 40 kg (88 lb)
• Water: 630 kg (1,390 lb)
