In a discovery as fascinating as it is chilling, NASA’s Mars Reconnaissance Orbiter has captured stunning, high-resolution images of intricate channels cutting across the Martian landscape. These ‘spidery’ formations, concentrated near the planet’s south pole, are unlike anything seen on Earth.

Scientists believe these bizarre channels form when vast sheets of frozen carbon dioxide, or dry ice, cover the Martian surface. As spring arrives, the trapped gas beneath the ice sheets warms, builds pressure, and eventually explodes through cracks in the ice. The force of these violent eruptions carves the intricate spider-like channels, throwing dust and sand skyward in the process.

The latest images, a collaborative effort between NASA and a dedicated group of citizen scientists, provide unprecedented detail. Volunteers pored over thousands of images from the Mars Reconnaissance Orbiter, painstakingly cataloging strange surface features to pinpoint areas deserving a closer look from the orbiter’s powerful HiRISE camera

The spiders appear clustered amidst a unique Martian terrain dubbed “basketball terrain” for its textured appearance. Further study of these alien landscapes could uncover vital clues about Mars’ volatile climate and the unique geological processes that sculpt its surface.
