A serpentine shape twists across the floor and walls of a canyon on Mars, suggesting the form of a dragon snaking across a clouded sky.
This image from the HiRISE camera on board the Mars Reconnaissance Orbiter shows light-colored material deposited onto the darker-toned surface, possibly through a flow of some sort, in a corner of a feature on Mars called Melas Chasma, which itself is the deepest part of the Valles Marineris canyon system – the largest yet discovered in the solar system.
The bluish hues seen above are not true-color; click here for a larger RGB view of the region.
