A new study reveals a hidden risk for Mars missions: astronauts could lose strength even if muscle size stays the same.

The study conducted by an international team of astronomers exposed mice to different levels of gravity in the orbital ...

Back on Earth, balance issues could arise. Continued monitoring showed that the brain orientation of the astronauts in the study slowly returned to normal. For those with the longest stays, ...

Videos of astronauts on the Moon show them often bouncing across the lunar surface, helped by the fact that the gravity of our satellite is just one-sixth of Earth’s surface gravity. That experience ...

The UK Space Agency and Cambridge-based firm LinkGevity are working with Lithuania-based Delta Biosciences to see how ...

Serious health issues could potentially become show stoppers for longer missions to the moon and Mars, so scientists are working hard to understand more about the health issues long distance ...

The space-faring mice spent about 28 days in those conditions before returning to Earth in April. Mortreux and her colleagues then analyzed the weight, strength and movement of the 23 surviving ...

Astronauts’ brains can change shape and shift positions during stays in space, according to a new study with implications for NASA’s goals to conduct long-duration missions to the moon and Mars. The ...

Before you ever set foot on a spacecraft bound for deep space, tiny replicas of your organs might make the journey first. Suspended in microgravity aboard a research mission, this organ-on-a-chip, or ...

IRVINE, Calif. (KABC) -- The technological challenge of getting to Mars is a huge hurdle, but it may be biology that holds humanity back from venturing to the red planet. A new UC Irvine study shows ...

NASA is sending the first Black and first female astronauts to the moon in an upcoming launch, marking the first journey to ...
