Mike Fincke claims he lost the ability to speak for twenty minutes while on the ISS.
Then his voice stopped working. No warning. No pain. He was awake. He was aware. He knew he wanted to speak. He could not.
- Source reportedAsserted
The source says the ISS lacks onboard CT and MRI capability for direct intracranial imaging.
The ISS has no MRI. No CT scanner. No way to look inside an astronaut’s head under any circumstances.
- Source reportedAsserted
The article states that NASA does not screen for Patent Foramen Ovale (PFO) in astronaut candidates.
NASA has never performed routine screening or evaluation for PFOs in astronaut candidates.
- InferenceAsserted
The article suggests that microgravity can cause blood clots due to venous stasis.
Microgravity fundamentally breaks how blood drains from your head. On Earth, gravity pulls blood downward. In orbit, it does not.
- Source reportedObserved
The article states that the Crew-11 medical evacuation was the first in the 25-year history of the ISS.
It was the first medical evacuation in the 25-year history of the International Space Station.
- InterpretationAsserted
The article suggests that the diagnostic gap on the ISS poses a significant risk for deep-space missions.
The ISS medical suite can stabilize you. It cannot diagnose you. And until that changes, every astronaut who flies beyond LEO accepts a risk that cannot be identified, cannot be treated, and cannot be evacuated from.
