Astronauts achieve historic first: medical X-rays taken in space

In a groundbreaking achievement for space exploration, astronauts on the Fram2 mission have successfully captured the first medical X-rays in orbit. This milestone promises to revolutionize healthcare for crews on long-duration space missions, particularly those heading to the Moon.

The results confirmed that this type of device can operate effectively in space and produce images with the required clarity to diagnose conditions such as fractures, a tool that crew members lacked until now.

The Fram2 mission, launched on March 31, 2025, aboard a SpaceX Crew Dragon, featured a four-person crew with no prior medical experience. They utilized a portable X-ray unit to image human bodies and various objects while orbiting Earth for three and a half days. The results confirmed the equipment's effectiveness in microgravity, producing clear images suitable for diagnosing conditions like fractures, a capability previously unavailable to astronauts.

Historically, space expeditions relied heavily on ultrasound for medical diagnostics. However, ultrasound requires a physical medium for its acoustic waves, limiting its use in the vacuum of space. X-rays, conversely, can function independently of such a medium, offering a more versatile diagnostic tool.

X-rays can be used even in a vacuum, unlike ultrasound, which requires a physical medium to propagate acoustic waves.

The primary challenge in bringing X-ray technology to space was the size, weight, and fragility of conventional equipment. Modern innovations have led to compact, portable devices that require minimal power, some even operating on solar energy. Dr. Sheyna Gifford, a key proponent of the project and an aerospace medicine specialist, aimed to prove that commercially available X-ray devices could function effectively in microgravity.

Conventional radiological apparatuses were excessively bulky, heavy, and fragile to tolerate a space launch. At the same time, they demanded high electrical consumption and presented drawbacks for capturing clear plates if the subject under evaluation made any movement.

Prior to the mission, the Fram2 crew underwent just four hours of training on the equipment. Once in space, they captured X-rays of a smartwatch, a hand, the abdomen, pelvis, and chest. The digital images were stored for immediate review, demonstrating the potential for real-time medical assessment far from Earth.
