Snap! Astronauts Just Took the First X-Ray Pictures Ever in Space!
Quick Summary
For the very first time ever, astronauts took real medical X-ray photographs while orbiting Earth. The results were just published in a major science journal. This discovery is a huge leap forward for keeping astronauts healthy on future missions to the Moon and Mars.
What Happened?
You have probably seen an X-ray before — maybe a doctor used one to check if you broke a bone. An X-ray is a special kind of photograph that can look right through your skin and show your bones and insides. Doctors use them all the time here on Earth.
But in space? Until now, no one had ever taken a real medical X-ray while actually orbiting Earth.
That changed in March 2025, when four private astronauts flew on a SpaceX Crew Dragon spacecraft called Fram2. The mission orbited Earth for about three and a half days. Before their flight, three of the crew members received four hours of training on a small, portable X-ray device. It was about the size of a small lunchbox.
While floating in orbit hundreds of miles above Earth, the astronauts used the device to take X-ray images of their own hands, arms, chests, and abdomens — all without any help from doctors on the ground.
The results were published this week in a top medical journal called Radiology. Scientists confirmed that the space X-ray images were good enough to be used to diagnose a real injury, like a broken bone. The quality was nearly as sharp as X-rays taken right here on Earth.
The device even photographed a smartwatch. This showed that the same technology could be used to inspect spacecraft parts for hidden cracks or damage — kind of like using an X-ray to peek inside a wall without taking it apart.
Why Does It Matter?
Right now, if an astronaut on the International Space Station gets hurt, doctors on Earth can talk to them by radio. But there is no way to take a real picture of a bone to see if it is broken. They have to guess.
Future missions to the Moon will take several days to travel. A trip to Mars would take months. Astronauts on those journeys will need to handle medical problems completely on their own.
Having a portable X-ray machine means astronauts could check for broken bones, internal injuries, or even damaged equipment — all by themselves, far from Earth.
Researchers also noted the same technology could be used in remote places on Earth where doctors are hard to reach. Think of a tiny village in the middle of a jungle or a research base in Antarctica.
Big Words
- X-ray — a type of energy wave that can pass through soft body parts and create pictures of bones and organs inside the body
- Orbit — the looping path a spacecraft travels around Earth, like a ball swung on a string
- Portable — small and light enough to carry from one place to another
- Microgravity — the condition in space where everything feels nearly weightless, because a spacecraft is in a constant gentle fall around Earth
- Diagnostic — describes a test that helps a doctor figure out what is wrong with a patient
Fun Fact
The portable X-ray machine used in space is so small and easy to use that similar devices are already used on the sidelines at sports events like the Super Bowl to quickly check if an injured player has a broken bone!
Think About It
If you were traveling to Mars and someone on your crew got hurt, what other medical tools do you think would be important to bring along?
