NASA scientists have successfully recreated the mysterious 'spiders' found on Mars, known as araneiform terrain, in a laboratory setting. These large, spider-like geological formations, first discovered in 2003, have been linked to the sublimation of carbon dioxide ice on the Martian surface. The study, led by planetary geomorphologist Lauren McKeown at NASA's Jet Propulsion Laboratory (JPL), utilized a specialized chamber called DUSTIE to simulate Martian conditions and observe the formation processes. The experiments confirmed the Kieffer model, which explains how sunlight heats the icy surface, causing gas to build up and crack the ice, thus creating the spider-like features. McKeown's excitement was palpable, as she recounted the breakthrough moment when the experiment succeeded, prompting a startled reaction from her lab manager. This advancement opens new avenues for understanding the geological processes on Mars.
