Nasa has decided to bring four astronauts, part of Crew-11, back from the International Space Station in the coming days due to a medical emergency that prompted the indefinite postponement of a planned spacewalk on January 8, 2026.
The issue emerged Wednesday afternoon with an unidentified crew member, leading the agency to prioritise the astronaut’s health above mission objectives.
Officials stress the situation is stable, with no immediate life-threatening concerns, but early repatriation ensures proper care on Earth.
The spacewalk, US EVA 94, was set for Thursday morning, involving astronauts Mike Fincke and Zena Cardman to upgrade solar arrays and power systems critical for ISS operations.
Fincke, a veteran with multiple spacewalks, and Cardman, on her first EVA, prepared extensively, but medical concern halted preparations abruptly.
Nasa confirmed the postponement late Wednesday, shifting focus to monitoring the crew member’s condition and planning logistics for a SpaceX Crew Dragon return.
Crew-11, launched months ago, includes American, Japanese, and Russian personnel conducting experiments in microgravity, biology, and technology.
The affected astronaut’s identity remains private, aligning with protocols that shield personal health data during missions.
Nasa Administrator Jared Isaacman noted the decision reflects rigorous safety standards, potentially shortening the rotation from its planned duration. A follow-up spacewalk on January 15 now faces review.
Microgravity poses risks like fluid shifts, bone loss, and vascular issues, with past incidents including venous thrombosis cases.
Crews train for emergencies using onboard medical kits and telemedicine with ground control, but Earth return becomes necessary for advanced diagnostics.
Similar events occurred in prior missions, such as Crew-8 in 2024, where post-landing care addressed undisclosed issues without derailing operations.
This development highlights the human challenges of space habitation at 400 km altitude, where every decision balances science and safety.
Nasa vows updates within 24 hours on return timelines and rescheduling, maintaining transparency while safeguarding the crew.
As President Trump’s administration supports expanded space efforts, the agency demonstrates resilience, ensuring the ISS continues vital research uninterrupted. Ground teams now orchestrate a swift, safe homecoming, underscoring their commitment to astronaut well-being above all.
