NASA confirms that Mars has air, but its composition and extremely low pressure raise a far more serious question: could a ...

NASA’s MAVEN spacecraft has confirmed, through nearly a decade of orbital observations, that solar wind physically strips gas from Mars’ upper atmosphere in a process called sputtering. That finding ...

Prefer Newsweek on Google to see more of our trusted coverage when you search. Mars' missing atmosphere may be locked up in the planet's clay-rich surface, a new study by MIT geologists has suggested.

Despite the absence of a global Earth-like magnetic dipole, the Martian atmosphere is well protected from the effects of the solar wind on ion escape from the planet. New research shows this using ...

For years, scientists have puzzled over how Mars lost the thick atmosphere it once had. That atmosphere was essential for liquid water to exist on the planet’s surface, billions of years ago. Today, ...

Mars' atmosphere has been of interest to scientists for decades, especially as humanity looks to set up outposts on the Red Planet. Recently, the European Space Agency's ExoMars Trace Gas Orbiter gave ...

A key tracer used to estimate how much atmosphere Mars lost can change depending on the time of day and the surface temperature on the Red Planet, according to new observations by NASA-funded ...
