An asteroid hurtles from space and strikes the surface of Mars, creating an impact crater. The hit causes a turbulent dust cloud to flow outward, scattering a thin layer of fine-grained material that settles up to 20 times the crater’s radius. Winds normally remove this deposit within a few weeks of its formation. But in certain areas of the planet, the deposits somehow resist erosion and survive for… Read more
Lessons from underground nuclear tests and explosive volcanoes may hold the answer to how a category of unusual impact craters formed on Mars.
The craters feature a thin-layered outer deposit that extends well beyond the typical range of ejecta, said Nadine Barlow, professor of physics and astronomy at Northern Arizona University. She… Read more
