BURSTThe martian landscape is not the easiest terrain to get around. Some areas are too rocky for a wheeled rover to cross, and elsewhere a lack of distinctive features in the landscape can cause problems for a camera-based navigation system. For a flying drone, such a navigation issue can mean the difference between a safe landing and a crash. Dielof van Loon, a student from Delft University of Technology, investigated what would happen if the two explorers – rover and drone – teamed up.
