NASA's MSL Curiosity rover has been closely examining "boxwork" formations, informally called Martian spiderwebs, in Gale Crater's Mt. Sharp foothills since August 2025. These low ridges, 1-2 meters tall, are believed to have formed from mineral-rich groundwater flowing through ancient underground fissures, indicating a past with liquid water. Curiosity's detailed analysis, including collecting and analyzing samples in its onboard laboratory using wet chemistry, has revealed long-chain hydrocarbons, the largest ever found on Mars, which are crucial building blocks for cell membranes on Earth. The high silica content suggests neutral or slightly acidic water, a potentially habitable environment for microbes. While the exact placement of mineral nodules within the boxwork remains unexplained, the findings are considered intriguing evidence for ancient Martian life, prompting further investigation as Curiosity continues its ascent of Mt. Sharp.
