China's Mars rover has uncovered underground polygon structures buried beneath the Red Planet's surface - and it looks like they're related to Mars' long-lost water, too.
Using this high-tech radar, the rover combed Utopia Planitia, a large plain in the planet's northern hemisphere where Zhurong's inactive husk still rests, to see what was happening below. The CAS team found, per Zhurong's readings, a total of 16 'polygonal wedges' in an area of about three-quarters of a square mile, 'suggesting a wide distribution of such terrain under Utopia Plainitia,' the Nature Astronomy paper explains.
