Study explains bright radar reflections on Mars without liquid water

by

Cornell University researchers have provided a simple and comprehensive—if less dramatic—explanation for bright radar reflections initially interpreted as liquid water beneath the ice cap on Mars’ south pole. Their simulations show that small variations in layers of water ice—too subtle for ground-penetrating radar instruments to resolve—can cause constructive interference between radar waves. Such interference can … Read more

Plate tectonics is not something most people would associate with Mars. In fact, the planet’s dead core is one of the primary reasons for its famous lack of a magnetic field. And since active planetary cores are one of the primary driving factors of plate tectonics, it seems obvious why that general conception holds. However, … Read more
