Terra Sirenum looking south

High altitude clouds of water ice crystals dominate this otherwise bleak lunar-like landscape. The perspective is from an altitude of 30 miles and about 50 from the south pole.

What's in a name?

Terra refers to any of the relatively light-colored highland areas on the surface of the moon or a planet.

Sirenum comes from Greek mythology and refers to the small rocky islands where the Sirens lived and lured sailors to their deaths.

This rendering is based upon elevation data from NASA's Mars Orbiter Laser Altimeter.
