NASA’s Perseverance rover has detected complex molecules of carbon on the surface of Mars. These compounds, known as macromolecular carbon, can be produced by living organisms, though that’s not the only way they might form.

On June 14, 2026, NASA's Perseverance Mars rover completed a marathon, or 26.2 miles (42.2 kilometers) as a spacecraft watched from orbit.

The organic molecules could come from life or from ordinary chemistry — only samples returned to Earth can settle it.

The Exploration Rover for Navigating Extreme Sloped Terrain (ERNEST) test rover has been put through its paces with great success.

After nearly five years on Mars, NASA's Perseverance rover has traveled almost 25 miles (40 kilometers), and the mission team has been busy testing the rover's durability and gathering new science findings on the way to a new region nicknamed "Lac de ...

Data from NASA’s Perseverance rover confirms the presence of macromolecular carbon on Mars – another potential piece of the puzzle in the search for life.
