NASA Astronaut’s Sudden Speech Loss Prompts First ISS Medical Evacuation

With a heart attack ruled out, NASA is reviewing astronaut records for signs of a microgravity link.

Overview

  • Mike Fincke, who suddenly could not speak for about 20 minutes on Jan. 7, says he felt no pain and recovered quickly.
  • NASA carried out a controlled medical evacuation, bringing Fincke and three Crew-11 crewmates home on Jan. 15 aboard a SpaceX Dragon and straight to a San Diego hospital.
  • The crew used the station’s ultrasound during the scare, but NASA opted for an early return to access advanced imaging not available in orbit.
  • Doctors have not found a cause, ruling out a heart attack and choking as investigators assess whether long time in weightlessness played a role.
  • The incident canceled a planned spacewalk and ended the mission more than a month early, and NASA sped up Crew-12’s launch to sustain station operations.
