NASA's Curiosity rover has captured close-up images of massive, web-like geological formations on Mars, dubbed "boxwork." These mineral-rich ridges, spanning up to 20 kilometers, are believed to have formed from ancient groundwater. Analysis of rock samples reveals calcium sulfate veins, suggesting a past watery environment potentially suitable for microbial life. The discovery on Mount Sharp is surprising due to the unique nature of the formations and their potential to unlock secrets about Mars' past habitability.
