Read the latest positive news, breakthroughs, and inspiring stories about astronaut health, curated daily by BrightWire.
NASA astronauts who spent six months aboard the International Space Station returned to Earth with healthy hearts, thanks to exercise regimens that protected them during prolonged spaceflight. The findings bring us closer to safely sending humans to Mars.
A coin-sized eye scanner could prevent astronauts from losing their sight on deep space missions. The quantum-powered device will help space agencies monitor and treat a condition that affects 7 in 10 astronauts.
Astronauts just captured the first diagnostic X-rays in orbit, using a portable device that could transform medical care on future space missions. Three crew members with only four hours of training proved the technology works as well in space as it does on Earth.
Three astronauts with just four hours of training took the first diagnostic-quality X-rays of human bodies during SpaceX's Fram2 mission, opening new possibilities for treating sick or injured crew on future deep-space voyages. For over 40 years, ultrasound has been the only imaging option available in orbit.
The four astronauts who circled the Moon in April are helping scientists understand how quickly humans can work after landing on other worlds. Their health data could shape the future of living and working on the Moon and Mars.
British inventors tested space gym equipment that could slash astronaut exercise time from 2 hours to just 30 minutes daily. Olympic rower Matthew Wells helped test the device in weightless conditions above Earth.
Three astronauts returned from an 18-day space mission with perfectly healthy joints, easing concerns about what microgravity does to the human body. Even better, researchers discovered a portable imaging tool that could revolutionize how doctors monitor astronaut health on future missions to the Moon and Mars.
A compact exercise device smaller than a shoebox delivered up to 500 pounds of resistance for astronauts on their historic 10-day journey around the Moon. NASA engineer Ryan Schulte and his team created the flywheel that helped the Artemis II crew stay physically and mentally strong in zero gravity.
A Scottish emergency room doctor is revolutionizing space medicine by teaching astronauts life-saving techniques for missions to the Moon and Mars. Dr. Christina Mackaill's work is preparing both space travelers and Earth-based doctors for humanity's next giant leap.
Scientists studied mice on the International Space Station and discovered a critical "gravity threshold" needed to maintain muscle strength. The findings could revolutionize how astronauts prepare for long Mars missions.
Before astronauts venture to the Moon or Mars, miniature versions of their organs might make the journey first. These tiny tissue chips could unlock safer, faster ways to protect humans in deep space.
Astronauts launching to the International Space Station will help solve a critical health mystery: why weightlessness might cause dangerous blood clots. Their research could protect future crews traveling to the Moon and Mars.
