NASA officials said Thursday they have decided to bring home four of the seven crew members on the International Space Station after one of them experienced a \u201cmedical situation\u201d earlier this week.<\/p>\n

The space agency has said little about the incident, and officials have not identified which crew member suffered the medical issue. James \u201cJD\u201d Polk, NASA\u2019s chief health and medical officer, told reporters Thursday the crew member is \u201cabsolutely stable\u201d but that the agency is \u201cerring on the side of caution\u201d with the decision to return the astronaut to Earth.<\/p>\n

The ailing astronaut is part of the Crew-11 mission, which launched to the station August 1 and was slated to come back to Earth around February 20. Instead, the Crew-11 astronauts will depart the International Space Station (ISS) in the coming days and head for reentry and a parachute-assisted splashdown in the Pacific Ocean off the coast of California.<\/p>\n

\u201cAfter discussions with our chief health and medical officer, Dr. JD Polk, and leadership across the agency, I\u2019ve come to the decision that it\u2019s in the best interests of our astronauts to return Crew-11 ahead of their planned departure,\u201d NASA Administrator Jared Isaacman said Thursday.<\/p>\n

The Crew-11 mission is led by commander Zena Cardman, 38, who is wrapping up her first mission to space. Second in command is pilot Mike Fincke, a 58-year-old astronaut on his fourth spaceflight. Japanese astronaut Kimiya Yui, 55, and Russian cosmonaut Oleg Platonov, 39, round out the crew.<\/p>\n

Isaacman said NASA will release more information about the schedule for Crew-11\u2019s undocking and reentry within the next 48 hours. The crew will come home aboard the same SpaceX Crew Dragon spacecraft they launched in more than five months ago. The entire crew must return to Earth together because they rely on the same Dragon spacecraft as a lifeboat.<\/p>\n

\u201cFor over 60 years, NASA has set the standard for safety and security in crewed spaceflight,\u201d Isaacman said. \u201cIn these endeavors, including the 25 years of continuous human presence onboard the International Space Station, the health and well-being of our astronauts is always and will be our highest priority.\u201d<\/p>\n

Lingering risk<\/h2>\n

Polk, a physician who has served as NASA\u2019s chief medical officer since 2016, said the agency is not ready to release details about the medical issue, citing privacy concerns. \u201cI\u2019m not going to speak about any particular astronaut or any particular specific diagnosis,\u201d Polk said. \u201cI\u2019d ask that we still respect the privacy of the astronaut.\u201d<\/p>\n

Two of the Crew-11 astronauts, Cardman and Fincke, were preparing to head outside the space station on a spacewalk early Thursday. Spacewalk preps at the space station include a period of time breathing high concentrations of oxygen to purge nitrogen from the astronauts\u2019 bloodstreams, a mitigation to avoid decompression sickness when crew members are sealed inside their spacesuits\u2019 pure oxygen atmosphere.<\/p>\n

Polk said whatever happened Wednesday \u201chad nothing to do\u201d with preparing for the spacewalk. \u201cThis was totally unrelated to any operations onboard,\u201d he said. \u201cIt\u2019s mostly having a medical issue in the difficult areas of microgravity with the suite of hardware that we have at our avail to complete a diagnosis.\u201d<\/p>\n

Yui radioed mission controllers in Houston on Wednesday afternoon requesting a private medical conference with a flight surgeon, then asked ground teams to turn on camera views inside the station ahead of the session. Medical sessions are carried out on private radio channels and are not heard on the regular communication loops between the space station and mission control. Those open loops are streamed around the clock online, but NASA removed the audio feed from YouTube soon after the crew asked for the medical conference.<\/p>\n

NASA publicly revealed a medical concern with one of the astronauts later Wednesday afternoon, then announced late Wednesday night that officials were considering bringing the crew home early.<\/p>\n

\u201cI won\u2019t go into specific details about the medical incident itself,\u201d Polk said. \u201cBut the crew is highly trained, and they came to the aid of their colleague right away, and that\u2019s part of why we do that training.\u201d<\/p>\n

The space station is stocked with medical gear and medications to help astronauts respond to emergencies. Crew members are trained to perform ultrasounds, defibrillate patients, and start IVs, among other things. The medical treatment available on the ISS is akin to what an EMT might provide in transit to a hospital, former astronaut Tom Marshburn, himself a medical doctor, said in 2021.<\/p>\n

\u201cWe have a very robust suite of medical hardware onboard the International Space Station, but we don\u2019t have the complete amount of hardware that I would have in the emergency department, for example, to complete the workup of a patient,\u201d Polk said.<\/p>\n

Space station managers will take a few days to determine when the Dragon spacecraft will leave the station. SpaceX will dispatch a recovery ship from Southern California to sail for the splashdown zone in the Pacific, and officials will assess weather and sea conditions before selecting the best opportunity to depart the station. Like every crew return, the vessel will be staffed with medical personnel to examine the astronauts after exiting from the Dragon capsule.<\/p>\n

,<\/p>\n

\u201cBecause the astronaut is absolutely stable, this is not an emergent evacuation,\u201d Polk said. \u201cWe\u2019re not immediately disembarking and getting the astronaut down.\u201d<\/p>\n

But without a confirmed diagnosis of the astronaut\u2019s medical issue, there\u2019s some \u201clingering risk\u201d for the astronaut\u2019s health if they remained in orbit, Polk said. That\u2019s why Isaacman and his deputies agreed to call an early end to the Crew-11 mission.<\/p>\n

This was the most significant decision of Isaacman\u2019s young tenure as NASA administrator. He was sworn in as NASA chief last month after clearing a confirmation vote in the Senate. Before taking the helm at NASA, Isaacman charted a career as an entrepreneur and private astronaut, flying to space twice on commercial missions with SpaceX.<\/p>\n

An inevitability<\/h2>\n

After Crew-11\u2019s departure, the space station will operate with a smaller crew of three until the arrival of SpaceX\u2019s Crew-12 mission with a fresh team of astronauts next month. Isaacman said NASA and SpaceX are looking at options to move up the launch of Crew-12 from its current target date of February 15.<\/p>\n

Until then, the station\u2019s crew will consist of NASA astronaut Chris Williams and two Russian cosmonauts, who launched to the space station in November on a Russian Soyuz vehicle. Williams and his crewmates\u2014Sergey Kud-Sverchkov and Sergey Mikayev\u2014have their own lifeboat in the Soyuz spacecraft, so they will still have a ride home in the event of a future emergency.<\/p>\n

The space station regularly operated with just three crew members for the first decade of its existence. The complex has been permanently staffed since 2000, sometimes with as few as two astronauts or cosmonauts. The standard crew size was raised to six in 2009, then to seven in 2020.<\/p>\n

Williams will be solely responsible for overseeing the lab\u2019s US segment until Crew-12 arrives. He will be busy keeping up with maintenance tasks, so managers will likely defer some of the station\u2019s scientific investigations until the complex is back to a full crew.<\/p>\n

,<\/p>\n

The early departure of Crew-11, leaving Williams as the only US astronaut aboard, also means NASA will be unable to perform spacewalks. This will mean a \u201cslightly elevated risk\u201d in NASA\u2019s ability to respond to a major hardware failure that might require a spacewalk to fix, said Amit Kshatriya, the agency\u2019s associate administrator.<\/p>\n

NASA and the Russian space agency, Roscosmos, inked an agreement in 2022 to fly multinational crews on Dragon and Soyuz missions to ensure an American and a Russian are always at the space station. The so-called \u201cseat swap\u201d deal is proving worthwhile with this week\u2019s events.<\/p>\n

NASA has never before cut short a human spaceflight mission for medical reasons. \u201cIt\u2019s the first time we\u2019ve done a controlled medical evacuation from the vehicle, so that is unusual,\u201d Kshatriya said.<\/p>\n

The Soviet Union called an early end for an expedition to the Salyut 7 space station in 1985 after the mission\u2019s commander fell ill in orbit.<\/p>\n

In a sense, it is surprising that it took this long. Polk said predictive models suggested the ISS would have a medical evacuation about once every three years. It ended up taking 25 years. In that time, NASA has improved astronauts\u2019 abilities to treat aches and pains, minor injuries, and routine illnesses.<\/p>\n

Crews in orbit can now self-treat ailments that might have prompted a crew to return to Earth in the past. One astronaut was diagnosed with deep vein thrombosis, or a blood clot, in 2018 without requiring an early departure from the space station. Another astronaut suffered a pinched nerve in 2021 and remained in orbit for another seven months.<\/p>\n

One of the more compelling reasons for the space station\u2019s existence is its ability to act as a testbed for learning how to live and work off the planet. The station has served as a laboratory for studying how spaceflight affects the human body, and as a platform to test life support systems necessary for long-duration voyages to deep space.<\/p>\n

\u201cWe are doing all this to continue to learn,\u201d Isaacman said. \u201cWe will absolutely learn from this situation as well, to see if that informs our future on-orbit operations, whether that be on the space station or our future lunar base that we\u2019re pursuing right now, and eventually for deep space missions to Mars.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
