US and Russian astronauts launch joint space mission from Baikonur

NASA chief Jared Isaacman made an uncommon trip to the Baikonur Cosmodrome in Kazakhstan, the historic launch site operated by Russia, to observe a scheduled launch on Saturday. The visit marked one of the few instances in recent years that a senior U.S. space official has traveled to the Russian‑run facility, underscoring the continued coordination between the two space agencies despite broader geopolitical tensions. Isaacman, who leads NASA’s human‑spaceflight initiatives, was escorted through the complex and attended the pre‑launch briefings before watching the liftoff of a Soyuz vehicle carrying a mixed crew of Russian and international astronauts bound for the International Space Station.

The launch, part of the ongoing rotation of crews to the orbiting laboratory, proceeded on schedule, with the Soyuz rocket lifting off from Site 31/6 at approximately 08:30 UTC. Mission control teams from both Roscosmos and NASA monitored the ascent and reported a nominal insertion into the station’s orbit. Isaacman’s presence was intended to reinforce collaborative ties and to assess operational procedures that could inform future joint missions, including upcoming Artemis endeavors. The successful launch concluded the day's activities at Baikonur, reaffirming the enduring partnership that underpins much of humanity’s presence in low‑Earth orbit.
