On November 27, a botched Soyuz MS-28 liftoff from Baikonur Cosmodrome in Kazakhstan heavily damaged the complex’s crewed launch pad. The Soyuz MS-28 crew—cosmonauts Sergey Kud-Sverchkov and Sergey Mikayev and NASA astronaut Christopher Williams—arrived safely at the International Space Station. Drone footage and expert analysis show major structural losses, including a mobile maintenance cabin inverted in the flame trench, and observers warn repairs could take months or years. NASA has publicly acknowledged the incident and said it is coordinating with international partners as inspections continue.
Key Takeaways
- The Soyuz MS-28 launch on November 27 successfully delivered three crew members to the ISS; no injuries were reported.
- Launch Pad 6 at Site 31 in Baikonur sustained extensive damage; drone imagery shows a maintenance cabin flipped into the flame trench.
- Experts interviewed by NASASpaceflight estimate repairs could require months to years, depending on component availability and logistics.
- That pad is Russia’s only currently certified site for crewed Soyuz launches, creating a single-point vulnerability for Russian crewed access.
- NASA confirmed it is aware of Roscosmos inspections and coordinates closely with partners for ISS operations; NASA referred mission-impact questions to Roscosmos.
- Russia reported reserve elements are available to restore the pad, but timelines remain unclear; a Progress cargo flight was delayed from December 21 to early next year.
- The next crewed Soyuz mission is scheduled for July 2026; Russia’s leadership has said it will support ISS operations at least through 2028.
Background
Baikonur Cosmodrome in Kazakhstan has been a linchpin of human spaceflight since the Soviet era and remains central to Russia’s crewed launch capability. Site 31, and specifically Launch Pad 6, has hosted recent Soyuz crewed missions; losing that infrastructure removes Russia’s primary domestic option for sending humans to low Earth orbit. Over the past decade, access to the International Space Station has diversified, notably with SpaceX’s Crew Dragon providing an alternative crew transport method since 2020.
Relations between Russia and the United States have been strained since Russia’s 2022 invasion of Ukraine, yet both countries have continued operational cooperation on the ISS. Russian statements in late 2024, including remarks by then-head Yuri Borisov, committed Moscow to supporting ISS operations through 2028, reversing earlier rhetoric about withdrawal. The differing political signals and the technical shock of a damaged pad add complexity to planners in Moscow, Houston, and partner agencies.
Main Event
On November 27, Soyuz MS-28 lifted off from Baikonur with a three-person crew bound for the ISS. Tracking and telemetry indicate the vehicle achieved a trajectory that allowed the crew to reach the orbital outpost and complete docking, but the pad experienced a destructive failure at or shortly after ignition. Visual evidence from drones showed a mobile maintenance cabin overturned into the pad’s flame trench, and other support elements were visibly damaged.
Specialist observers who reviewed imagery and site reports told NASASpaceflight that repair will be complex because the pad integrates heavy mechanical and electrical systems with specialized ground-support hardware. Some components are unique or stored in limited numbers, and international supply lines for replacements could be slow. Roscosmos issued a brief Telegram notice acknowledging damage to multiple pad elements and saying reserve parts exist to restore operations.
NASA issued a statement saying it is aware of Roscosmos’s inspections of Launch Pad 6 at Site 31 and reiterated that it coordinates closely with international partners for safe ISS operations. The agency confirmed the MS-28 crew arrived safely but pointed reporters to Roscosmos for questions about the pad’s repair timeline and impacts on future Russian missions. Roscosmos had not provided detailed repair schedules by press time.
Analysis & Implications
The immediate operational implication is a loss of Russia’s only certified crewed launch pad, creating a gap in national launch capacity. With Soyuz as a principal crew taxi and only SpaceX Crew Dragon available as an alternative, ISS crew rotation and contingency planning will need re-evaluation. For short-term crew safety, redundancy exists via existing Dragon missions and manifest changes, but longer-term reliance on a single foreign provider raises strategic and programmatic risks.
Repair complexity and timing matter for mission manifests beyond crew rotation. A delayed Progress resupply flight—moved from December 21 to an unspecified date next year—illustrates how cargo flows and station consumables planning are already being affected. If repairs stretch into many months, Roscosmos and international partners may need to shift launch manifests, reassign payloads to commercial vehicles, or replan logistics and crew increment lengths.
Politically, the incident tests Russia’s public commitment to the ISS through at least 2028. Restoring a heavily damaged pad will require funding, management focus, and possibly international coordination for parts or technical support. If Russia accelerates restoration, the program may absorb near-term costs; if repair stalls, partners will face increased pressure to cover crew and cargo access through alternatives such as commercial US vehicles or extended station consumables management.
Comparison & Data
| Capability | Status | Typical Crew Capacity | Next Scheduled Crewed Flight |
|---|---|---|---|
| Soyuz (Baikonur Launch Pad 6) | Damaged Nov 27, 2025; inspections ongoing | 3 | July 2026 (planned) |
| SpaceX Crew Dragon | Operational; launches from US | 4–7 (varies) | Depends on commercial manifest (operational alternative) |
This table summarizes the immediate crew access landscape: Soyuz remains the traditional Russian capability but its primary pad at Baikonur is under repair, while Crew Dragon is available as an operational alternative for crew transport. Supply ship cadence, like the delayed Progress mission, is already being rescheduled pending pad repairs.
Reactions & Quotes
NASA said it is aware Roscosmos is inspecting Launch Pad 6 and that it coordinates with international partners to ensure ISS safety.
NASA (agency statement)
Roscosmos acknowledged damage to several launchpad elements and stated reserve parts exist to restore the facility.
Roscosmos (Telegram notice)
An industry official cautioned that the real test will be how quickly and fully Russia commits resources to repair the pad and maintain its ISS contributions.

Unconfirmed
- The precise timeline for full restoration of Launch Pad 6 is not confirmed; industry estimates range from months to years depending on parts and approvals.
- The extent to which the damage will force permanent changes to Russian crew launch strategy, including greater reliance on foreign providers, remains uncertain.
- Roscosmos’s claim that reserve elements will allow rapid restoration has not been independently verified with a detailed parts inventory or repair schedule.
Bottom Line
The November 27 incident at Baikonur removed Russia’s prime certified crewed-launch site from immediate service, though the MS-28 crew reached the ISS safely. Operationally, the event compresses contingency options: partners must juggle resupply and crew rotation while Roscosmos assesses and repairs the pad. In the short term, commercial crew providers such as SpaceX offer alternative access, but program managers face complex logistics and political choices if repairs extend into 2026 or beyond.
For policymakers and ISS partners, the priority will be securing crew safety and station sustainment while clarifying repair timelines and resource commitments. The coming weeks of inspections, parts assessments, and official schedules from Roscosmos will determine whether this is a temporary disruption or a prolonged capability gap that reshapes near-term human access to low Earth orbit.
