NASA’s next Mars rover will land at the foot of a mountain inside a 96-mile-wide crater named Gale. The space agency selected Gale Crater over another crater named Eberswalde. The mountain in Gale Crater is layered, and scientists believe it is the surviving remnant of an extensive sequence of deposits.
The contest is accepting entries in one or all of four categories: wildlife, landscapes, underwater and aerials. The grand-prize winner will receive $10,000, publication in National Geographic Magazine and a feature on National Geographic’s Instagram account.
