The Obliquity of Mars (Periodic Bedding in Tithonium Chasma)

Earth's seasons are caused by the tilt of our planet's rotational axis to the orbital plane or obliquity. Mars' obliquity is currently about 25 degrees, which is not much different from Earth's 23 degrees. (Audio by Tre Gibbs. Enhanced color images are 1 km across.)

Rippled Surfaces on a Slope in Coloe Fossae

This observation shows us a set of landforms that appears to form a nested "chevron" pattern on a slope in Coloe Fossae. Interestingly, nearby surfaces on the same slope are all parallel. (Audio by Tre Gibbs. Enhanced color images are 1 km across.)
