– A Circular Crack

The first thing anyone thinks of when they see circular features on Mars is a crater. Is that the case here?

– Layers, Dunes and Cliffs in Hydrae Chasma

Hydrae Chasma is a deep, circular depression that has steep walls flanked by numerous landslides and a massive scarp along its southern boundary.

– Monitoring a New Impact Site in Fortuna Fossae

This impact site is located on the floor of a large fracture within Fortuna Fossae, formed sometime between September 2005 and May 2008.

– A Defrosting Mess

Just like on the Earth, the frost layer that accumulates over the winter will disappear as summer approaches and Mars heats up.
