ISS Ultrasound Hinted at Astronaut Medical Emergency
23 Jan
Summary
- Portable ultrasound used during a January 7 medical emergency on the ISS.
- Ultrasound scans monitor cardiac and eye health in microgravity.
- This was NASA's first medical evacuation in 65 years.

Astronauts returning from the International Space Station have offered insight into a medical emergency that triggered a rare evacuation. Mike Fincke, a pilot on the mission, indicated that a portable ultrasound machine was instrumental in managing the situation on January 7.
This technology is vital for monitoring astronauts' cardiac systems and eye health in the unique environment of space. Microgravity can cause fluid to shift, increasing risks like blood clots and contributing to spaceflight-associated neuro-ocular syndrome.
The emergency led to NASA's first medical evacuation in 65 years and the first-ever evacuation of the ISS. A planned spacewalk was cancelled on January 8, with the crew's return accelerated and set for January 10.
While NASA has been discreet about the specifics, the use of ultrasound suggests a serious medical concern requiring immediate diagnostic capabilities. The crew emphasized that extensive training and available equipment were crucial for handling the unforeseen circumstances.
Portable ultrasound devices are recommended for all future spaceflights due to their effectiveness in diagnosing and monitoring astronaut health in real-time. This incident underscores the ongoing challenges and advancements in maintaining crew well-being during long-duration space missions.
