That’s exactly what a study published today in Science Advances sought to do. The researchers exposed mice aboard the ISS to ...

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

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 ...

Mars used to have a warmer and wetter climate, which changed after billions of years because the Sun's solar wind removed ...

A look at how local resource use, material innovation, and autonomous construction are enabling practical habitat development ...

Elon Musk says his obsession with the red planet is cooling.

Mars didn’t always look like the barren world we see today. Over billions of years, the Sun’s solar wind stripped away much of its atmosphere, helping transform it from a warmer, wetter planet into a ...

But Mars Express belongs in the same breath as those films, not because it vibes hard with them, but because it delivers something startlingly novel and fully realized that every sci-fi work should be ...

Scientists compare volcanic cones on Earth and Mars to explain how gas-rich magma forms scoria cones. Spacecraft observations and Earth analog sites provide evidence of similar eruptive processes.

Geological features like these provide evidence that Mars once had a denser atmosphere and significant surface water — ...
