New Command on ISS Ahead of Retrieval Mission - NASA cuts ISS mission short due to undisclosed astronaut health issue

NASA has brought four astronauts back from the International Space Station (ISS) earlier than planned. The decision follows an undisclosed medical issue affecting one crew member, marking the first such incident in the station's history. Their capsule landed safely in the Pacific Ocean off the coast of California on Thursday.

The Crew-11 mission, originally set to run until August 2025, was cut short due to health concerns. NASA did not reveal which astronaut was affected or the nature of the problem. The crew—Zena Cardman, Mike Fincke from NASA, Kimiya Yui from JAXA, and Oleg Platonov from Roscosmos—began their return journey on Wednesday.

Before departure, Mike Fincke formally handed over command of the ISS to Russian cosmonaut Sergei Kud-Sverchkov. The new commander's role includes maintaining team unity and coordinating with ground control. NASA may now accelerate the launch of the replacement crew, originally scheduled for mid-February.

The early return prioritised the health of the astronauts, with all four landing safely in the Pacific. This marks the first time an ISS crew has been brought back ahead of schedule for medical reasons.

The astronauts are now back on Earth after their shortened mission. Their replacement crew could launch sooner than planned, depending on NASA's assessment. The agency has not provided further details on the medical issue or the affected individual.
