A decade on Mars: How the Curiosity rover confirmed the planet's ancient habitability

Ten years after landing in Gale Crater, NASA's Curiosity rover has fundamentally changed our understanding of Mars. This report details the mission's findings regarding the planet's past environment and previews the rover's ongoing search for clues about how long life might have persisted there.

Since landing on August 5, 2012, Curiosity has successfully addressed its primary objective: determining whether Mars could have supported ancient life. Scientists have confirmed that the answer is yes, shifting the mission's focus toward understanding the planet's historical climate transitions and the duration of its habitable periods.

Deputy Project Scientist Abigail Fraeman explains that the rover is currently navigating new terrain to investigate how Mars changed over time. The video also clarifies how the team processes visual data; by exaggerating color variations in images, researchers can better interpret the landscape. While some processed photos appear to show a blue sky, the actual Martian sky would appear pinkish to a human observer.
