In a groundbreaking move, NASA has decided to bring an astronaut team back to Earth prematurely from the International Space Station (ISS) following a medical emergency in space. This marks the first instance in the 25-year history of the ISS that a mission is ending early due to health concerns.

NASA Administrator Jared Isaacman announced on Thursday that a crew member experienced a medical issue on January 7. The individual is currently stable, but after thorough discussions with medical experts and agency leaders, the decision was made to expedite the crew’s return.

“For more than six decades, NASA has been a leader in ensuring the safety and security of human spaceflight,” stated Isaacman during a press briefing. “The health and well-being of our astronauts is and will always be our top priority.”

Isaacman confirmed that the SpaceX Dragon Endeavour spacecraft will return the Crew-11 team to Earth within the next few days, ahead of their originally scheduled departure later this year. The crew had launched to the ISS in August and was initially slated for a six to eight-month mission.

The crew includes Commander Zena Cardman, pilot Mike Fincke, Japan Aerospace Exploration Agency astronaut Kimiya Yui and Russian cosmonaut Oleg Platonov.

Space historian and NASA expert Rod Pyle said the decision represents a historic first in U.S. human spaceflight.

“The declaration of a medical emergency in space is unprecedented, certainly in the operation of the International Space Station, which has been crewed continuously for 25 years,” Pyle said. “They did have one notable medical emergency, in the past, when an astronaut suffered deep vein thrombosis, but they were able to actually stabilize that in orbit and continue on the mission.”

“This is the first time in the history of the ISS. And as far as I remember, the first time in the history of the American space program, where somebody had to be brought home early, in effect, evacuated from orbit.”

Pyle, who worked at NASA’s Jet Propulsion Laboratory and the Johnson Space Center, lauded Isaacman’s decision to return to come back to Earth, while discussing the research implications.

“The ripple effects of this are pretty significant. Certainly, they’re nothing as serious as having a life-threatening medical issue,” he said. “So it’s the right decision for them to come home. And I think we’re all happy that Jared Isaacman was in the seat to make that decision as the new NASA administrator. I think he handled this very well.”

Pyle explained that nearly half the astronauts’ time on the ISS is spent on research and daily activity, while the other time is spent on maintenance and repair due to the space station’s condition.

“Now some of that load will probably be handed off to the astronauts that remain behind. That’ll be three of them. But this does throw a bit of a ripple into the works. And what’s kind of critical about that, this would be important at any time, but we don’t have a lot of time left with the International Space Station as it is being de-orbited in 2030. It remains to be seen how quickly the private companies will be replacing it.”
