Until now, there really hasn't been a lot of reliable medical imaging options for monitoring astronaut health during spaceflight. Now, a team of scientists has revealed the promising results of the first diagnostic X-rays taken during an orbital spaceflight. In the past, X-ray machines took up too much room and used too much power to be considered for space flights. New technology has changed this — you can even find portable X-ray machines at sports games and low-resource areas since they run on solar energy. Gifford's team took X-ray images of a hand during a simulated space flight in 2022 to show it was possible to get a clear image in microgravity — this prompted the next phase of testing in orbit.
