Progress MS-33
Progress MS-33, Russian production No. 463, identified by NASA as Progress 94, is a Progress cargo spacecraft mission by Roscosmos to resupply the International Space Station. It will be the 186th flight of a Progress spacecraft and was originally scheduled to launch in late 2025, but was delayed indefinitely due to damage at Baikonur Cosmodrome Site 31 following the launch of Soyuz MS-28.
Mission
Progress MS-33 was scheduled to launch on 19 December 2025 and after a two-day free flight, dock with the zenith port of the ISS's Poisk module.However, Site 31 at the Baikonur Cosmodrome was severely damaged during the launch of Soyuz MS-28, with the mobile service platform beneath the pad appearing to collapse into the flame trench. The extent of the damage temporarily rendered Russia’s only operational crewed launch facility unusable. Roscosmos officials subsequently told NASA that repairs to the site and restoration of launch capability were expected to take at least four months. As a result, the next planned launch from the site—the Progress MS-33 cargo mission originally scheduled for late December—was delayed to no earlier than March.
In response to the disruption, NASA adjusted its cargo resupply schedule to the ISS. The agency moved the CRS SpX-34 forward by one month, from June 2026 to May, and advanced the subsequent CRS SpX-35, by three months, from November to August. NASA indicated that the changes were intended to ensure adequate food, water, oxygen, and other critical supplies aboard the station in the event of further delays to visiting Progress vehicles.
