For the first time, scientists have directly observed atmospheric sputtering in action on Mars — an erosion process driven by solar wind ions that may have played a major role in the planet’s atmospheric and water loss. ScienceAlert reports: The only …

Evidence is mounting for “a vast reservoir of liquid water” on Mars, according to a new article by Australian National University professor Hrvoje TkalÄiÄ and geophysics associate professor Weijia Sun from the Chinese Academy of Geological Sc…

Billions of years ago Mars “had a warm, habitable climate with liquid water in lakes and flowing rivers,” writes Ars Technica.

But “In order for Mars to be warm enough to host liquid water, there must have been a lot of carbon dioxide in the atmosphe…
