Astronauts on SpaceX's Fram2 mission successfully captured diagnostic X-ray images in orbit for the first time. The milestone gives space medicine a second imaging option beyond ultrasound and could help future crews diagnose injuries, inspect equipment, and support longer missions to the moon or beyond. Popular Science reports: Commercial off-the-shelf X-ray machines like the ice cooler-sized MinXray TR90BH now allow users to perform scans on subjects far away from traditional facilities. In 2022, [Mayo Clinic researcher Sheyna Gifford] assisted in preparing a crew to successfully generate digital X-rays while experiencing microgravity during a parabolic flight. Gifford's team then spent years collaborating with SpaceX to plan another feasibility study. This time, they didn't want to operate an X-ray machine aboard an aircraft simulating the conditions in space -- they intended to use the equipment during an orbital mission.
The process was detailed in a recently published study in the journal Radiology, and focuses on last year's Fram2 mission. Instead of days of medical training, astronauts spent only four hours learning how to use their portable radiography device. They then took preflight X-rays of a hand, forearm, chest, abdomen, and pelvis ahead of their SpaceX Falcon 9 rocket launch on March 31, 2025. Once in orbit, the team calibrated the system before testing their MinXray on the same body parts as well as a smartwatch.
Once the crew returned, a trio of independent radiologists reviewed the orbital X-ray images based on their positioning, spatial and contrast resolutions, and general scan quality. Although positioning scores were slightly decreased for the central body images, every other scan held up to similar examples created on Earth. Meanwhile, the astronauts reported that using the machine was easy despite minimal prior coaching. Looking ahead, researchers hope to conduct further X-ray tests during orbital missions, while continuing to reduce the overall size of equipment.
