NASA Crew Splash Down On Earth Successfully After Medical Issue: Four astronauts, Zena Cardman, Mike Fincke, Kimiya Yui and Oleg Platonov successfully splashed down in the Pacific Ocean off San Diego in their SpaceX Dragon capsule after 10-hours journey from the International Space Station due to an unexpected medical issue on January 15.
According to the National Aeronautics and Space Administration (NASA), one of the four astronauts who returned to Earth had a 'medical concern', but did not reveal the name of the astronaut or the medical issue due to health privacy. The decision to return the astronaut, accompanired with the rest of the crew for medical evaluation back on earth Friday, after a planned spacewalk was cancelled on Friday.
NASA astronaut E. Michael Fincke took to social media to share his thoughts about why the mission was cut short. "First and foremost, we are all OK," he wrote on LinkedIn. "Everyone on board is stable, safe, and well cared for. This was a deliberate decision to allow the right medical evaluations to happen on the ground, where the full range of diagnostic capability exists. It's the right call, even if it's a bit bittersweet."

The astronauts who recently splashed down to earth are part of the SpaceX Crew-11 mission, which was launched in August 2025 and was scheduled to last for at least six months aboard the International Space Station (ISS). Reportedly, this is the first time in the space station's 25-year history that, due to a medical problem in orbit, a mission is forced to be cut short.
The National Institute of Health (NIH) explains that no matter how healthy astronauts are, they can face a variety of health problems when on board at the ISS and after returning to the earth. This typically occurs because astronauts face unique environments and biological adaptations such as fluid shift, plasma volume loss, bone density loss, and muscle atrophy. The US health agency states that the absence of noise and natural light can also disrupt circadian rhythms, resulting in sleep issues, fatigue and changes in physical and mental health.
In his LinkedIn post, Fincke further wrote, "We're leaving the ISS in great hands." Talking about his 167 days in space, Fincke said, "This moment also highlights the strength of NASA's Commercial Crew Program and our partnership with SpaceX. Dragon provides a safe, reliable, and flexible capability to bring us home on short notice when it's the right thing to do."
He added, "We're leaving the ISS in great hands. The three crewmates who arrived in November will continue the mission, and they'll be joined by Crew-12 in just a few weeks. Explore 74! We're grateful for the teamwork, proud of the mission, and looking forward to coming home soon back to our loved ones and to resolving any medical questions with the best care available."
