Russia's Soyuz MS-28 spacecraft successfully launched on November 27, carrying two Roscosmos cosmonauts and one NASA astronaut to the International Space Station (ISS). However, the routine mission was overshadowed by a launch pad collapse at Site 31/6 in Baikonur Cosmodrome.
According to reports, the structure's mobile maintenance cabin collapsed shortly after liftoff, sending photos of the damage flooding social media. Drone footage revealed the site's mobile maintenance cabin lying upside down in the flame trench. Roscosmos stated that the damage occurred due to "launch-related issues," and an inspection is currently underway.
The collapse has resulted in Russia being temporarily cut off from the ISS until repairs can be completed. Site 31/6, the only Russian launch site capable of launching astronauts and cargo to the ISS, is now out of commission. Despite this, the crew currently on board the ISS will not be stranded due to the delay.
The maintenance cabin is a massive structure weighing around 144 tons. It was placed beneath the rocket before launch with its lifting platforms in place. The team would then lower the platforms and move the maintenance cabin into an enclosed "nook" under the launch pad, where it could conduct final preparations. However, it appears that the cabin's locks were either not properly secured or failed to withstand the load, leading to the collapse.
RussianSpaceWeb.com reported that the incident likely occurred some moments after liftoff, with photos of the launch capturing no signs of failure. As the rocket launched, a pressure difference between the space beneath it and the enclosed area where the maintenance cabin was stored likely caused the structure to be pulled out of position and thrown into the flame trench.
Photos posted online show extensive damage to the maintenance cabin, suggesting that it may be beyond repair. Roscosmos will need to install a spare or build a new one before resuming launches at Site 31/6. The repairs are expected to take up to two years, with no clear timeline for when the site will reopen.
The collapse of the launch pad has raised concerns about Russia's ISS launch schedule. A critical cargo mission, Progress MS-33, scheduled to launch on December 21, may now be delayed. Additionally, a crewed Soyuz MS-29 mission set to launch in July 2026 could also be postponed due to the incident.
