NASA Astronauts Reflect on Return to Earth and Medical Precautions Taken After ISS Mission

Three NASA astronauts, who spent nearly eight months aboard the International Space Station (ISS) before returning to Earth in October, spoke publicly for the first time since their return and subsequent medical evaluations. They were briefly hospitalized upon their return “out of an abundance of caution,” according to NASA, but assured the public they are in good health. NASA is currently investigating the specifics of their post-flight health incident, which remains largely confidential due to medical privacy laws.

Michael Barrett, the mission pilot, addressed the media at a press briefing in Houston. He shared limited details about their experience, emphasizing that space flight continually reveals unexpected medical challenges that scientists and astronauts are still working to understand. He stated, “Space flight is still something we don’t fully understand. We’re finding things that we don’t expect sometimes – this was one of those times.”

Barrett, a medical doctor and an advocate of space medicine, highlighted the importance of learning how human bodies adapt to and are affected by extended space travel. He noted that more information would be shared when NASA’s investigation is complete.

The three U.S. astronauts, including mission commander Matthew Dominick and flight engineer Jeanette Epps, were taken to Ascension Sacred Heart Hospital in Pensacola immediately following their splashdown in the Gulf of Mexico on October 25. Russian cosmonaut Alexander Grebenkin, who was part of the same crew, was not at the press conference. NASA stated that one of the astronauts, who has not been publicly identified, was briefly held at the hospital for additional observation but was released soon after in good health.

At the press conference, the astronauts described their experiences adjusting to life on Earth again. Dominick explained some of the physical discomforts they encountered, such as the sensitivity of sitting on a hard surface after months in microgravity. “The big things you expect, being disoriented, being dizzy. But the little things, like just sitting in a hard chair … it’s rather uncomfortable,” he said.

Dominick also recounted the difficulty of readjusting to family life. Just days after his return, he struggled to stay comfortable while eating a meal with his family. Eventually, he chose to lay down on a towel rather than sit on a hard chair.

The mission was originally scheduled to conclude in August, but the crew was asked to extend their stay on the ISS due to delays in Boeing’s Starliner mission, which faced technical challenges. As a result, the Starliner’s crew, Butch Wilmore and Suni Williams, remain on the ISS and are expected to return no earlier than February of next year.

After the delay, the crew’s return was further postponed due to adverse weather conditions in the Gulf of Mexico, including Hurricane Milton, which caused dangerous conditions in early October. Dominick recounted the uncertainty they faced while awaiting their return, describing the back-and-forth nature of their departure plans as “entertaining to deal with.” Despite the delays, he expressed appreciation for the unexpected additional time in space.

The astronauts’ briefing offered a glimpse into the unique challenges of long-duration space missions and the ongoing work to understand and adapt to the effects of space on the human body. Barrett, Dominick, and Epps all expressed optimism about future research in space medicine and the potential for expanding human presence in space with these findings.
