Space Station Sickness: A Mystery Unfolds
A 59‑year‑old former Air Force officer, who has flown to space four times, reported a sudden illness while dining on the International Space Station (ISS). The incident occurred just days before a scheduled spacewalk, prompting an immediate response from his crew and ground‑based medical support.
Duration & Symptoms
The episode lasted about twenty minutes. During this time, the astronaut could not speak and did not report pain, yet his teammates observed distress and surrounded him. Emergency protocols were activated, and an onboard ultrasound was used to assess his condition.Medical Findings
After returning to Earth, doctors ruled out a heart attack and confirmed he was not choking. The cause remains unknown, though the astronaut suggested it might be linked to over 549 days of microgravity exposure—a factor known to affect many bodily systems.
Agency Response
The space agency is reviewing medical records of other astronauts to check for similar events. The astronaut also emphasized protecting crew members’ medical privacy so they can perform duties without fear of personal information exposure.Impact on Operations
The sickness forced the cancellation of a planned spacewalk that would have been his tenth. It also led to an early return for the crew, who were flown back by a commercial space company and received hospital care shortly after landing.Outlook
Despite the surprise and challenges, the astronaut remains optimistic about future missions. He credits his overall health for surviving the episode and views it as a reminder of how unpredictable space can be.
