Soyuz MS-28 Launch Successful Amid Critical Baikonur Launch Pad Damage

Soyuz MS-28 Mission: Successful Docking Overshadowed by Baikonur Launch Pad Failure

On November 27, 2025, the global space community witnessed a complex event characterized by both operational success and significant ground infrastructure failure. The Russian Soyuz MS-28 spacecraft successfully lifted off from the Baikonur Cosmodrome in Kazakhstan, delivering a three-person crew to the International Space Station (ISS). The mission, carrying Roscosmos cosmonauts Sergey Kud-Sverchkov and Sergey Mikaev, along with NASA astronaut Chris Williams, proceeded according to flight parameters, with the spacecraft docking safely with the ISS approximately three hours after launch.

However, the successful orbital insertion was immediately followed by reports of catastrophic damage to the launch infrastructure at Site 31/6. During the liftoff sequence, a critical support structure known as the “service cabin” or mobile service platform failed to retract or lock correctly. Consequently, the immense force of the rocket’s exhaust blasted the structure off its rails, causing it to collapse into the flame trench below. This incident has raised immediate concerns regarding the operational status of Russia’s human spaceflight program.

The significance of this event cannot be overstated. Since the retirement of the historic Site 1 (“Gagarin’s Start”) in 2020, Site 31/6 has served as the sole operational launch pad for crewed Soyuz missions. With the primary infrastructure now sustaining major structural damage, the timeline for future launches remains uncertain. We must now analyze the technical specifics of the failure and the conflicting narratives regarding the repair timeline to understand the broader implications for international space cooperation.

Technical Breakdown of the Site 31/6 Incident

To understand the severity of the damage, it is necessary to examine the specific component that failed. The damaged structure is the Service Cabin (known in Russian as Kabina Obslyzhnivaniya). This massive, multi-level scaffolding is integral to pre-launch operations. It allows technicians access to the rocket’s first and second stages for final inspections, fueling line connections, and the securing of hold-down arms. In standard operations, this cabin retracts into a protective niche prior to ignition to avoid the destructive power of the rocket’s plume.

Reports indicate that during the launch of Soyuz MS-28, the mechanism designed to retract or secure the cabin failed. As the rocket ascended, the exhaust plume struck the exposed structure, tearing it from its mountings and leaving it as a “crumpled mess” in the exhaust pit. This is not merely a cosmetic issue; the service cabin is a custom-built, complex mechanism essential for preparing a rocket for flight. Without it, fueling and finalizing a Soyuz rocket for launch is operationally impossible.

The immediate aftermath confirmed that while the crew was safely en route to the ISS, the ground facility suffered critical damage. This creates a logistical bottleneck. The Baikonur Cosmodrome, leased by Russia from Kazakhstan, currently has no other certified pad ready to support human spaceflight. The redundancy that once existed with multiple active pads has been eroded over the last decade due to funding constraints and the retirement of older facilities.

“As of today, Russia has effectively lost the ability to launch humans into space, something that hasn’t happened since 1961.”

Conflicting Narratives: Repair Timelines and Future Viability

A significant divergence has emerged between official state statements and independent expert analysis regarding the recovery timeline. Roscosmos, the Russian state space corporation, has publicly acknowledged “damage to a number of elements of the launch pad” but maintains an optimistic outlook. Official channels have stated that the necessary spare parts are available in reserve and that repairs will be completed “very soon.” This narrative suggests that the damage, while dramatic, is manageable within the existing supply chain.

Conversely, independent experts present a far more cautious, if not alarming, assessment. Anatoly Zak, the publisher of RussianSpaceWeb, has estimated that repairs to such a complex, custom-engineered structure could take up to two years. The service cabin is not a standard “off-the-shelf” component; it requires precise engineering to ensure the safety of future crews. If the damage involves the structural foundation of the pad or the rail mechanisms, a quick fix using spare parts may not be sufficient to recertify the site for human spaceflight.

The lack of immediate backup options complicates the situation further. Russia’s new Vostochny Cosmodrome in the Far East was intended to eventually host crewed missions, but it is not yet certified for Soyuz human launches. Certification for Vostochny was projected for the 2026–2027 timeframe. Additionally, the Plesetsk Cosmodrome, while capable of launching Soyuz rockets, is a military site not equipped or certified for ISS crew rotations. This leaves the program in a precarious position, dependent entirely on the speed and success of repairs at Site 31/6.

Implications for the ISS and International Logistics

The grounding of Site 31/6 has immediate ripple effects on the International Space Station’s logistics. The next scheduled Launch from this site was the uncrewed cargo mission, Progress MS-33, slated for December 21, 2025. Given the extent of the damage described by independent observers, it is highly probable that this mission will face delays. A prolonged inability to launch cargo vessels could impact the resupply chain for the station, although other partners currently provide cargo capabilities.

Of greater concern is the schedule for crew rotations. If repairs extend into months or years, as suggested by some analysts, Russia will be unable to rotate its cosmonauts using domestic hardware. This scenario would force a total reliance on the SpaceX Crew Dragon for all ISS crew transportation. While the international partnership is resilient, losing the redundancy of two independent crew launch systems introduces new risks and places additional strain on the remaining operational fleet.

We are currently in a waiting period to see if Roscosmos can substantiate its claim of a rapid repair. The coming weeks will be critical as engineers assess the structural integrity of the flame trench and the availability of the required replacement components. Until Site 31/6 is recertified, the Soyuz MS-28 crew remains safe aboard the ISS, but the path for their successors remains unclear.

Concluding Section

The launch of Soyuz MS-28 will be remembered as a moment of stark contrast: a flawless ascent and docking set against the backdrop of a crumbling infrastructure. While the primary objective of delivering the Expedition 74 crew, Sergey Kud-Sverchkov, Sergey Mikaev, and Chris Williams, was achieved, the destruction of the service cabin at Site 31/6 exposes the fragility of Russia’s current spaceflight capabilities. The incident highlights the risks associated with relying on a single point of failure for critical access to space.

As the situation develops, the space industry will be watching closely to see if the optimistic repair schedules provided by Roscosmos hold true, or if the pessimistic projections of independent experts come to pass. The outcome will determine not only the schedule of upcoming ISS missions but also the broader strategic landscape of human spaceflight in the mid-2020s.

FAQ

Was the crew injured during the incident?
No. The crew of Soyuz MS-28 (Sergey Kud-Sverchkov, Sergey Mikaev, and Chris Williams) arrived safely at the International Space Station. The damage occurred to the ground infrastructure after the rocket had already lifted off.

What exactly was damaged?
The primary damage was to the “service cabin” (mobile service platform) at Site 31/6. It failed to retract properly and was blown into the flame trench by the rocket’s exhaust, suffering major structural damage.

Can Russia launch from a different launch pad?
Currently, no. Site 31/6 is the only active pad certified for crewed Soyuz launches. The historic Site 1 is retired, and the new Vostochny Cosmodrome is not yet certified for human missions.
