NASA Unveils Mystery Behind Mars Spiders
Originally Published 6 months ago — by ZME Science
NASA researchers have successfully recreated the spider-like geological structures on Mars, known as araneiform terrain, in a lab by simulating the planet's cold, low-pressure conditions. These features are formed by seasonal sublimation of CO2 ice, which causes gas buildup and surface cracking, creating the distinctive spider shapes. The findings help understand Mars' climate history and geological processes.
