Astronauts say space station’s ultrasound machine was critical during medical crisis

Four astronauts were evacuated from the International Space Station last week following a medical emergency that occurred January 7, marking NASA's first medical evacuation in 65 years of human spaceflight. The crew successfully used the space station's portable ultrasound machine to help manage the undisclosed medical crisis, with astronaut Mike Fincke calling it "super handy" and advocating for ultrasound devices on all future spaceflights. The emergency forced the cancellation of a planned spacewalk and shortened their mission to 5½ months.
