History

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:[7][8][9]

  • 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.[7][8][9]
  • Enhanced redundancy thanks to the addition of a backup system of electrical motors for the docking and sealing mechanism.[7][8][9]
  • Improved Micrometeoroid (MMOD) protection with additional panels in the cargo compartment.[7][8][9]
  • Luch Russian relay satellites link capabilities enable telemetry and control even when not in direct view of ground radio stations.[7][8][9]
  • GNSS autonomous navigation enables real time determination of the status vector and orbital parameters dispensing with the need of ground station orbit determination.[7][8][9]
  • 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.[7][8][9]
  • Unified Command Telemetry System (UCTS) replaces previous Ukrainian Chezara Kvant-V as the Progress spacecraft's on-board radio and antenna/feeder system.[7][8][9]
  • Replacement of the Kurs A with Kurs NA digital system.[7][8][9]

Launch

A Soyuz-2.1a launched Progress MS-26 to the International Space Station from Baikonur Site 31/6 on 15 February 2024.[10][11] Later, Progress MS-26 automatically docked with Zvezda and is continuing its mission on 17 February 2024, supporting Expedition 70 aboard the ISS.[12][13][11]

Cargo

The MS-26 cargo capacity is 2,518 kg (5,551 lb) as follows:[6]

  • Dry cargo: 1,478 kg (3,258 lb)[6]
  • Fuel: 580 kg (1,280 lb)[6]
  • Oxygen: 580 kg (1,280 lb)[6]
  • Water: 420 kg (930 lb)[6]
  • Nitrogen: 40 kg (88 lb)[6]
