Mission
The mission was initially scheduled to use Soyuz MS vehicle No. 759, which was next in line for assembly at Energia's factory in Korolyov. During post-production testing, the spacecraft reportedly sustained major damage to its heat shield that could not be repaired in time for the planned launch at the end of 2025. Reports suggested that the shield was either detached when its pyrotechnic bolts were inadvertently triggered (similar to the procedure that occurs shortly before landing) or that its thermal layers delaminated during a poorly executed test. As of October 2025, Roscosmos had not acknowledged the incident, but photographs released from the Baikonur Cosmodrome showed that Soyuz MS vehicle No. 753 was being prepared for flight. [1]
Vehicle No. 753, along with No. 752, had originally been allocated for prospective commercial missions. Vehicle No. 752 was used for the Soyuz MS-20 space tourism flight, but following Russia's invasion of Ukraine, commercial contracts with the Russian space program were cancelled. As a result, No. 753 was reassigned to regular International Space Station operations. The substitution also allowed Roscosmos to utilize the older spacecraft before its onboard systems exceeded their certified service life. [1]
Preparations for launch began in early October 2025 at the Baikonur Cosmodrome, including testing of the spacecraft's Kurs rendezvous system, leak checks in a vacuum chamber, and verification of propulsion, guidance, and communications systems. [1]
The Soyuz-2.1a launch vehicle and payload fairing for the mission arrived by rail at Baikonur on 22 October 2025. [1]
The mission launched successfully on 27 November 2025 at 09:27:57 UTC (14:27:57 AQTT, local time at the launch site), [2] and the crew arrived at the ISS a little over three hours later at 12:34 UTC. However, the launch pad at Site 31 was damaged during the launch, with the mobile service platform beneath the pad appearing to have collapsed into the flame trench. The extent of the damage temporarily rendered Russia's only operational crewed launch facility unusable. The status of the next planned launch from the site, the Progress MS-33 cargo mission scheduled for late December, was not immediately clear. In the hours following the incident, Roscosmos issued a statement saying it was assessing the situation, had the necessary spare parts, and expected repairs to be completed soon. [4] [5]
On the other side, the arrival of Soyuz MS-28 meant that all eight docking ports aboard the ISS are occupied following the reinstallation of Cygnus NG-23 to Unity module on 1 December 2025. It was held on Canadarm2 away from its docking port on 24 November 2025 to provide docking clearance to MS-28. The space station currently hosts: two SpaceX Dragon 2 spacecraft (Crew-11 and CRS-33), the Northrop Grumman Cygnus XL freighter (NG-23), the JAXA's HTV-X cargo ship (HTV-X1), Roscosmos Soyuz MS crew vehicles (MS-27 and MS-28), and two Progress MS cargo spacecraft (MS-31 and MS-32).

On the lower stage of this rocket, the Unity Foundation in collaboration with Roscosmos, wrapped the fuselage with art painted by children from across the world. This project dubbed "The Art Rocket" and "Rocket of Dreams" was an artistic expression for these kids with cancer, enabling them to send their dreams to space. [7] [8] [9]
