If we're to land humans on Mars in the coming decades, we'll have to know what challenges await them when they get there.

Mars' atmosphere is over 100 times thinner than Earth's and is primarily composed of carbon dioxide, nitrogen and argon gases.

“Ozone and CO2 are important in Mars’ atmosphere,” Trokhimovskiy said. “By not accounting for these gases properly, we run the risk of mischaracterising the phenomena or properties we see.” ...

New research suggests that Mars' missing atmosphere, long a mystery for planetary scientists, could be hiding within the ...

A Mars orbiter run by the European Space Agency (ESA) has sniffed out two never-before-seen chemical signatures in the Red Planet's atmosphere. This discovery could solve a longstanding Martian ...

New findings from NASA show that violent solar storms likely launched Martian gases out into space years ago in a process still in motion today. Mars' atmosphere was likely 'blown away' by the sun ...

Enough CO2 remained as gas in the atmosphere to create the greenhouse effect, ... Venus has roughly the same concentration of CO2 as Mars, yet its atmosphere went in precisely the opposite direction.

As the sun grew hotter, so did Mars, prompting much of its atmospheric carbon dioxide to rain out and ultimately get locked ...

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.

The rods could be made out of iron and aluminum naturally found on Mars, according to the paper, and would settle ten times slower than natural Martian dust particles, staying in the atmosphere ...

The dominant explanation relies on an interaction between the sun's rays and gases in the atmosphere. Mars lost its protective magnetic field billions of years ago, likely allowing high-energy ...
