We take you in amazing views of a virtual tour of one of the oldest valleys on the Red Planet - Mawrth Vallis. It is 2 kilometers wide, stretches for as much as 600 kilometers and separates the southern highlands and northern lowlands of Mars.
This movie, based on images taken by ESA’s Mars Express, highlights Mawrth Vallis, a 600 km-long, 2 km-deep outflow channel at the boundary of the southern highlands and the northern lowlands of Mars.
