NASA's Curiosity rover is currently exploring the Martian surface, focusing on intriguing boxwork formations. These web-like ridges, formed by ancient groundwater activity, are providing valuable insights into Mars' geological history and past water presence. This close-up study of the formations is a significant step in understanding the planet's evolution.
In April 2025, Curiosity captured detailed images of these formations on Mount Sharp within Gale Crater. These formations, some extending up to 12 miles, are thought to have developed when groundwater flowed through rock fractures, depositing minerals. The rover is now preparing to drill into a target named "Altadena" near the formations to analyze samples.
Studying these structures offers crucial clues about Mars' transition from a wet to a dry environment. The presence of minerals like calcium and magnesium sulfate suggests that liquid water once existed, potentially creating conditions favorable for microbial life. As of June 2025, Curiosity continues to analyze samples from the Altadena site, aiming to uncover more about Mars' geological history and the potential for past life.
