NASA has ordered its first-ever medical evacuation from the International Space Station after an astronaut fell ill with a "serious" but undisclosed issue, according to officials. The crew of four, led by US Commander Zena Cardman, is expected to return to Earth in the coming days, earlier than planned.
The decision comes after a series of hurried NASA statements about a medical situation that arose on Wednesday, forcing the agency to cancel its first spacewalk of the year. NASA Administrator Jared Isaacman described the condition as "serious" and said that even if a doctor had been aboard, the agency would still have wanted to bring the astronaut home.
The sick crew member was now stable but there was a "lingering risk," said NASA's chief health and medical officer, Dr James Polk. The issue has not been properly diagnosed, and officials are unsure what it might be.
Despite the severity of the situation, Isaacman praised the swift effort across the agency to ensure astronaut safety, saying, "I'm proud of the swift effort across the agency thus far to ensure the safety of our astronauts."
The ISS will not be left empty, as three other people are living and working aboard. The US astronaut Chris Williams and Russia's Sergei Mikayev and Sergei Kud-Sverchkov arrived in November on board a Soyuz rocket for an eight-month stay.
This is only the second time a space agency has ended a space station mission early due to health concerns, following a 1985 incident where cosmonaut Vladimir Vasyutin returned from the Soviet station with an infection and high fever. The aging ISS is set to be retired by late 2030 or early 2031, with plans to slowly burn it up over time so that some debris falls into the ocean.
