Soyuz MS-27 Mission Overview
NASA astronaut Jonny Kim, alongside Roscosmos cosmonauts Sergey Ryzhikov and Alexey Zubritsky, is set to return to Earth aboard the Soyuz MS-27 spacecraft after completing a 245-day mission on the International Space Station (ISS). The crew will undock from the ISS's Prichal module at 8:41 p.m. EST on December 8, 2025, and is expected to land in Kazakhstan at 12:04 a.m. EST on December 9, 2025. This mission marks Kim and Zubritsky's first journey to the ISS, while Ryzhikov concludes his third spaceflight.

The return process includes several key events:
- December 7, 2025: Change of command ceremony at 10:30 a.m. EST, where Ryzhikov will hand over command to NASA astronaut Mike Fincke.
- December 8, 2025:
- 4:45 p.m. EST: Farewells and hatch closing coverage begins.
- 8:15 p.m. EST: Hatch closing.
- 8:41 p.m. EST: Undocking from the ISS.
- 10:30 p.m. EST: Deorbit and landing coverage begins.
- 11:10 p.m. EST: Deorbit burn.
- December 9, 2025: 12:04 a.m. EST: Landing in Kazakhstan.
Importance of the ISS
The ISS has been continuously inhabited for over 25 years, serving as a vital platform for scientific research and international collaboration. As the station approaches its planned deorbit around 2030, NASA is focusing on deep space missions, including the Artemis program aimed at returning humans to the Moon and preparing for future missions to Mars. The ISS National Laboratory, managed by the Center for the Advancement of Science in Space (CASIS), will continue to facilitate research and commercial opportunities in low Earth orbit until the station's retirement.
Criticism & Opposition
While the ISS has been praised for its contributions to science, there are concerns regarding the future of human spaceflight as the station nears its end. Critics argue that the transition to commercial spaceflight may not adequately replace the scientific capabilities currently provided by the ISS. The reliance on commercial partners for transportation and research raises questions about the continuity and quality of future space exploration efforts.
Official Statements & Responses
NASA has emphasized the significance of the ISS in advancing scientific knowledge and preparing for long-duration space missions. In a statement, NASA Administrator nominee Jared Isaacman noted the agency's commitment to maximizing the scientific value of its budget. Additionally, Ramon Lugo, CEO of CASIS, expressed gratitude for NASA's continued partnership, stating, “We are honored that NASA has extended this unique partnership through 2030.”
