NASA reveals 'honeycomb' terrain on Mars

Speckling the surface of one of Mars' oldest impact basins, NASA's Mars Reconnaissance Orbiter has spotted a sprawling expanse of'honeycomb' landforms, with individual cells of up to 6 miles wide. The origin of these textured features has long remained a mystery, as scientists debate which type of natural process could be responsible, from glacial events to wind erosion. It's possible that multiple processes are at play, according to NASA, with evidence suggesting the honeycombs and the surrounding landscape in Mars northwestern Hellas Planitia may still be undergoing activity today.

According to NASA, the area has features of different natural processes, suggesting activity may still be reshaping the land today.
