Time moves differently on Mars — not in the Tibetan philosophy sense of the word, but in a measurable, physics-will-ruin-your-mission kind of way that's giving NASA engineers a real headache. As the ...

Ancient ripple layers on Mars capture a single sandstorm, helping scientists estimate how dense the planet’s atmosphere once ...

Mars' gravity has a surprisingly large influence on Earth, affecting our planet's tilt and orbit and thereby contributing to climate cycles lasting hundreds of thousands to millions of years, new ...

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 ...
