From the rover's point of view on the ground, it's hard to tell, but this ancient shoreline on Mars seemed to lie inside a 2,050-mile-wide (3,300-kilometer-wide) impact crater called Utopia Basin.

Scientists appear to have unravelled the mystery of Mars' "Martian dichotomy" - a contrast between its southern highlands and northern lowlands that's puzzled experts for over half a century.
