The Progress MS-33 ISS resupply 2026 mission marks the resumption of Russian cargo flights to the International Space Station (ISS) from the recently repaired Site 31/6 launch pad at Baikonur Cosmodrome. This launch comes nearly four months after Soyuz MS-28 caused extensive damage to the pad, delaying subsequent missions.
Progress MS-33 ISS Resupply 2026: Launch Schedule
- Launch date: Sunday, March 22, 2026, at 11:59 UTC
- Docking with ISS: Tuesday, March 24, 2026, around 13:34 UTC at the Poisk module
- Cargo load: Over 2,500 kg of food, fuel, and supplies
- Duration docked: Approximately six months before deorbit
The spacecraft, also known as Progress 94 by NASA, will be unloaded and eventually filled with trash for a controlled reentry over the South Pacific.
Damage and Repair at Site 31/6
Soyuz MS-28 Launch Incident
- During the Soyuz MS-28 launch on November 27, 2025, a mobile maintenance cabin under the rocket was improperly secured.
- Launch forces caused the platform to fall into the flame trench, severely damaging the pad.
- Without the platform, Progress and Soyuz launches from Site 31/6 were impossible.
Restoration Efforts
- Roscosmos sourced a spare platform from the 1970s and modified it for current launches.
- The repairs were completed in time to support the spring launch of Progress MS-33.
- Successful repair ensures Russia can continue cargo and crew launches to ISS.
Docking and ISS Operations
Docking Procedures
- Progress MS-33 will dock to the Poisk module, following the recent undocking of Progress MS-31 on March 16.
- Other vehicles at ISS:
- Progress MS-32 docked to Zvezda module’s aft port
- Soyuz MS-28 docked to Rassvet module
Role in ISS Supply Chain
- Supplies include fuel, water, and essential consumables for the Russian segment.
- Docking allows for resupply, orbital reboosts, and continued support of crewed operations.
Historical Context of Baikonur Launch Pads
Site 1/5 (Gagarin’s Start)
- Famous for Sputnik (1957) and Yuri Gagarin’s first human flight (1961).
- Last used for Soyuz MS-15 in 2019; now under Kazakhstan control and set to become a museum.
Site 31/6
- Currently the only operational Russian pad for ISS missions.
- Site 31/6 is critical until the ISS is decommissioned and replaced by Russia’s Orbital Service Station (ROSS).
Vostochny Cosmodrome Limitations
- Cannot currently handle Progress launches or provide safe abort options for Soyuz crewed missions.
Future Russian ISS Missions
- Progress MS-34: Scheduled April 25, 2026
- Soyuz MS-29 crewed launch: Scheduled July 14, 2026
ISS Operational Extension
- NASA Authorization Act of 2026 proposes extending ISS operations until September 30, 2032, ensuring continued collaboration with Russia.
