A new portable X-ray device made by a South Korean company will be taken aboard a NASA spacecraft to help keep astronauts healthy and support equipment checks during missions. The device, called the Xcam6, was developed by Remedi, a company specializing in small, low-dose X-ray machines.
NASA began searching for a compact X-ray device in 2023 to support its ‘Mini X-ray Technology Demonstration’ project. The need arose because astronauts can face a variety of medical issues during space travel, and X-rays can help diagnose at least 36 of 119 possible conditions. After reviewing over 200 products from around the world, NASA chose three finalists in May 2024: Remedi from South Korea, MinXray from the United States, and Fujifilm from Japan.
The selection process lasted about a year and a half and was led by NASA’s Glenn Research Center. The devices were tested for their ability to take clear images of bone fractures and dental damage in astronauts. The tests also checked if the X-rays could detect hidden cracks or problems in spacesuits and spacecraft equipment, all without the need to take anything apart. Their toughness was also assessed, as devices must survive strong vibrations and shocks during launch and re-entry to Earth.
One important part of the process was a performance check at Cleveland University Hospital. The Xcam6 was compared to standard hospital X-ray machines to see how well it worked on real patients. Based on these results and other tests, NASA decided the Xcam6 was the best choice.
Later this year, the Xcam6 will fly aboard a SpaceX crewed spacecraft, orbiting between 200 and 2,000 kilometers above Earth. Astronauts can use it to quickly check for bone injuries or dental issues that may happen during spacewalks or as a result of the low gravity, which weakens bones. Besides human health, the device will also help inspect spaceship structures and equipment for hidden damage. If it performs well, NASA may use it for future missions on the International Space Station and even on lunar exploration missions under the Artemis program. Remedi hopes their technology will also be used in South Korea’s future space trips.
