Table of Contents
A medical incident aboard the International Space Station prompted a care team to complete a full workup from ground facilities, as officials explained the on‑board medical suite could not conduct every necessary test in space.
The episode led to a continued emphasis on crew safety,with three astronauts remaining aboard the ISS while the situation is evaluated on the ground using the full range of medical testing equipment not available onboard.
The three-person ISS contingent currently aboard includes Russian cosmonauts Sergei Mikaev and Sergey Kud-Sverchkov, along with NASA astronaut Chris Williams.
Crew-12, featuring NASA astronauts jessica Meir and Jack Hathaway, together with Russian cosmonaut Andrey Fedyaev and European Space Agency astronaut Sophie Adenot, is slated to head to the ISS on February 15.
In parallel, NASA is advancing its artemis II mission, which will send Canadian Space Agency astronaut Jeremy Hansen and NASA astronauts Reid Wiseman, Christina Koch and Victor Glover around the Moon. The launch window is no earlier than february 6.
the public portrait of NASA’s SpaceX Crew-11, showing Oleg platonov, Mike Pincke, Kimiya Yui and Zena Cardman, serves as a reminder of the broad collaboration behind spaceflight.
Officials said the incident highlights the inherent challenges of operating in space, while underscoring NASA’s commitment to safeguarding its crew through careful monitoring and readiness.
