Supersaturated water vapor in Martian atmosphere Date: October 10, 2011 Source: CNRS (Délégation Paris Michel-Ange) Summary: Analysis of data collected by the European Space Agency's Mars ...

An international team of researchers has found a larger-than-expected amount of water vapor in Mars' upper atmosphere. The scientists believe seasonal changes are largely responsible for the ...

Once, Mars was a warm planet that could potentially support life and water on its surface. But something changed about 3.5 billion years ago and it lost most of its atmosphere. Only a thin ...

and Mars is now a dry, arid place. Water exists there only in the form of ice near its poles and in tiny quantities of water vapor in its atmosphere. The question that remains is: How did this happen?

which is orbiting Mars as part of the ExoMars program, and found that seasonal changes influenced how water vapor was distributed in the planet's atmosphere. "The loss of water from Mars to space ...

With less gravity than Earth, Mars has a harder time holding onto its atmosphere, and over the course of a billion years or so huge amounts of water vapor could drift off into space. While some of ...

When you look at Mars today it’s hard to even imagine ... Storms like that one can essentially siphon water vapor into the atmosphere where it is at risk of being stripped away from the planet ...

We already know that ice exists at the planet's poles and that its thin atmosphere contains water vapor. We even know ... liquid water once existed on Mars. “The shape of the ripples could ...

Billions of years ago, it likely had a thicker atmosphere rich incarbon dioxide and water vapor, creating a greenhouse effect ...
