Scientists are a step closer to solving a 40-year-old mystery about some unusual-looking craters on Mars.
Called double-layered ejecta (DLE) craters, these features attracted research attention because their debris patterns do not match the typical understanding of how craters are formed.
Craters are pockmarks that form on the surface of a planet or moon when a high-speed rock smashes into the surface. The fast-moving collision sprays out dirt and other debris in a ring. There are more than 600 craters on Mars that have two layers of this debris, however. A new study suggests a glacial landslide would have created the second layer. Read more…
