Scientists model Mars climate to understand habitability

A Southwest Research Institute scientist modeled the atmosphere of Mars to help determine that salty pockets of water present on the Red Planet are likely not habitable by life as we know it on Earth. A team that also included ...

Life on Mars theory boosted by new methane study

Scientists have ruled out the possibility that methane is delivered to Mars by meteorites, raising fresh hopes that the gas might be generated by life on the red planet, in research published tomorrow in Earth and Planetary ...

The four most promising worlds for alien life in the solar system

The Earth's biosphere contains all the known ingredients necessary for life as we know it. Broadly speaking these are: liquid water, at least one source of energy, and an inventory of biologically useful elements and molecules.

MAVEN's top 10 discoveries at Mars

On June 17, NASA's MAVEN (Mars Atmosphere and Volatile Evolution Mission) will celebrate 1,000 Earth days in orbit around the Red Planet. Since its launch in November 2013 and its orbit insertion in September 2014, MAVEN ...

Curiosity finds evidence of Mars crust contributing to atmosphere

NASA's Curiosity rover has found evidence that chemistry in the surface material on Mars contributed dynamically to the makeup of its atmosphere over time. It's another clue that the history of the Red Planet's atmosphere ...

Scientists detect water vapour emanating from Mars

Researchers said Wednesday they had observed water vapour escaping high up in the thin atmosphere of Mars, offering tantalising new clues as to whether the Red Planet could have once hosted life.

What happened to Mars? A planetary mystery

Billions of years ago when the planets of our solar system were still young, Mars was a very different world. Liquid water flowed in long rivers that emptied into lakes and shallow seas. A thick atmosphere blanketed the ...

ChemCam findings hint at oxygen-rich past on Mars

The discovery of manganese oxides in Martian rocks might tell us that the Red Planet was once more Earth-like than previously believed. A new paper in Geophysical Research Letters reveals that NASA's Curiosity rover observed ...
