Progress ISS Resupply
 

Progress MS-24 (Russian: Прогресс МC-24), Russian production No.454, identified by NASA as Progress 85P, is a Progress spaceflight launched by Roscosmos to resupply the International Space Station (ISS).[1][2] It is the 177th flight of a Progress spacecraft. It is planned to remain docked for approximately six months before performing a destructive reentry loaded with trash.[3]

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:[4][5][6]

  • 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.[2]

Launch

A Soyuz-2.1a launched Progress MS-24 to the International Space Station from Baikonur Site 31 on 23 August 2023.[7] Around 2 days after the launch, Progress MS-24 automatically docked with Zvezda and continues its mission, supporting Expedition 70 aboard the ISS.[7]

Cargo

The MS-24 cargo capacity is 2,500 kg (5,500 lb) as follows:[8][9]

  • Dry cargo: 1,535 kg (3,384 lb)
  • Fuel: 500 kg (1,100 lb)
  • Oxygen: 0
  • Nitrogen: 40 kg (88 lb)
  • Water: 420 kg (930 lb)[10]
