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 ...

Humans did not evolve for space. Ironically, because we insist on going there anyway, scientists now know from studying ...

How does Mars influence Earth’s climate cycles? This is what a recent study published in the Publications of the Astronomical Society of the Pacific hopes to address as a trio of researchers from the ...

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 ...

It's well known that spaceflight causes muscle atrophy and other biological changes in reduced gravity, and especially in ...

Small but mighty, the red planet — our celestial neighbor — has made Earth’s climate what it is today. Mars’ gravitational pull serves as a stabilizing force for our home’s orbit, tilt and position ...
