Rover finds hints of an ancient Martian carbon cycle

Rather than cycling, some of Mars’ carbon took a one-way trip into rocks.

Scientists probe the mystery of Titan's missing deltas

For scientists who want to learn about the geological history of a planet, river deltas are a great place to start. Deltas gather sediment from a large area into one place, which can be studied to reveal climate and tectonic histories or signs of past life. That's why NASA sent its most recent Mars rover to Jezero Crater, home to a prominent and well-preserved delta.

Scientists reveal signs of crucial life-sustaining process on Mars: 'I knew right away how important this discovery was'

Samples drilled by the Curiosity rover on Mars have revealed abundant signs of a carbon cycle that remained hidden from orbital scans, alongside clues of how life may have been wiped out on the planet.

Curiosity Finds First In Situ Evidence of Carbon Cycle on Ancient Mars

A surprise discovery in Gale Crater is the component that was missing in the puzzle of Mars's climate history.

A NASA rover finally found Mars’ missing carbon

The Curiosity rover identified hidden caches of the mineral siderite, which could help explain why Mars lost its habitable climate.
