South Korean scientists have developed a 3D-printed material capable of blocking radiation in space. This breakthrough promises to reduce health risks in long missions, such as a trip to Mars. For the public, this means space exploration will be safer and more accessible, with potential applications in radiation protection on Earth. The invention brings the possibility of living and working off the planet closer.
Polymers and nanotechnology against cosmic radiation 🛡️
The team from the Korea Institute of Science and Technology combined polymers with tungsten and bismuth particles, creating a filament for 3D printing. Tests showed that the material reduces exposure to gamma rays and high-energy particles by up to 40%. Its porous structure allows for greater flexibility than current metal shielding. Researchers claim it can be customized to fit suits or spacecraft, optimizing weight and protection without compromising astronaut mobility.
Goodbye sunscreen, hello anti-radiation suit 😂
Astronauts will be able to forget about applying SPF 10,000 cream every two hours, although they might have to deal with a suit that looks like it came from a space hardware store. That said, if the material also works on Earth, frequent air travelers could request tungsten blankets instead of neck pillows. Meanwhile, scientists promise that the next prototype won't make noise when walking, which is what really concerns the crew.
