Curiosity finds strange boxwork ridges on Mars that hint at ancient underground water. Scientists are now drilling for answers.

NASA's Curiosity rover explored Mars' Gale Crater, finding "boxwork" patterns and evidence of ancient waterways, providing clues about the red planet's watery past.

Landing on Mars' Gale Crater in 2012, the rover has traversed 21 miles (34 kilometers) of the 96-mile-wide (154 km) meteor impact crater, dutifully investigating the geology within.

The Perseverance rover has captured new images that appear to show evidence of a fast-flowing river that once fed into Jezero Crater, the site of an ancient Martian lake.

Curiosity has spent over a decade in the Gale Crater, the Martian landmark in which it landed in 2012. The 100-mile-wide crater was formed by an asteroid impact some 3.5 to 3.8 billion years ago.
