Soyuz MS-27 Crew Safely Docks at ISS for Eight-Month Mission

NASA astronaut Jonny Kim and Russian cosmonauts Sergey Ryzhikov and Alexey Zubritsky arrive at the ISS to conduct 50 scientific experiments and advance international space collaboration.

The Soyuz MS-27 spacecraft launched from the Baikonur Cosmodrome on April 8, 2025, at 1:47 a.m. EDT and docked with the ISS at 4:57 a.m. EDT after a three-hour journey.
NASA astronaut Jonny Kim, a former Navy SEAL and Harvard-trained physician, is joined by Russian cosmonauts Sergey Ryzhikov and Alexey Zubritsky on this mission.
The eight-month mission will involve 50 scientific experiments and technology demonstrations, focusing on long-term human spaceflight and advancing future exploration goals.
The mission highlights continued US-Russia cooperation in space exploration, a relationship that has endured despite broader geopolitical tensions.
This marks the first spaceflight for Kim and Zubritsky, while Ryzhikov embarks on his third mission, underscoring the Soyuz spacecraft’s decades-long reliability.
