NASA’s Curiosity rover has discovered a long-sought geological structure on Mars, dubbed “spiderwebs,” which suggest the Red Planet once had flowing water. The boxwork ridge structure, spanning 12 miles across, indicates groundwater spread across this area in the past, unlike what was previously observed from orbit.
The formation occurs via a similar mechanism to stalagmites and stalactites on Earth, with minerals accumulating in cracks and fissures before hardening as they dried. Despite Martian winds eroding rocks over time, these resistant ridges remain, revealing networks of underground water activity.
This discovery raises new questions about the Red Planet’s past, when rivers, lakes, and possibly an ocean existed. Scientists are eager to learn why water on Mars eventually dried up, transforming it into a cold desert. Further research will help answer these questions and shed light on Mars’ watery past.
