Their model suggested that Mars' surface could contain up to 1.7 bar of CO2—roughly 80 percent of its early atmospheric volume—sequestered as methane within clay deposits.

In a recent discovery that has sent shockwaves through the scientific community, NASA’s Perseverance rover uncovered ...

New research suggests the atmosphere of Mars may be hiding in plain sight, having been absorbed by minerals in the Red Planet's clays. If Mars' envelope of gas did "go to ground" over 3 billion ...

This study suggests that Mars' missing atmosphere might be stored in its clay-rich crust. MIT researchers propose that olivine-rich rocks on Mars interacted with water, converting atmospheric ...

Rocks on Mars would have interacted with water containing CO2 from the atmosphere. Researchers said that over several billion years, this process could have stored enough CO2 in the clay surface ...

All evidence points to Mars having had a carbon dioxide-rich atmosphere billions of years ago, but insufficient carbonates in Martian soil challenge this theory. Now, a new study using data from ...

Mars’s atmosphere is thin and made up of primarily carbon dioxide. When condensed by cool temperatures and mixed together with dust and water vapour, it can create striking cloud patterns.

Explaining persistent hydrogen in Mars' atmosphere New insight into Red Planet's hot again, cold again history Date: January 28, 2025 Source: Harvard John A. Paulson School of Engineering and ...

MIT research suggests Mars’ missing atmosphere — which dramatically diminished 3.5 billion years ago — could be locked in the planet’s clay-covered crust. Water on Mars could have set off ...

Chris Herd, a University of Alberta geologist, has helped in the study of the meteorite, in which traces of Mars' unique atmosphere are trapped.

"In some ways, Mars' missing atmosphere could be hiding in plain sight." The team's research was published Sept. 25 in the journal Science Advances.
