NASA Mars Reconnaissance Orbiter HiRISE Images: January 15, 2014

Status Report From: Jet Propulsion Laboratory
Posted: Saturday, January 18, 2014

- Dunes on the Rim of the Hellas Impact Basin

Sand dunes like these in this image have been observed to creep slowly across the surface of Mars through the action of the wind.

- Recent Volcanism in Valles Marineris

The possibility of recent volcanism inside Valles Marineris was first proposed decades ago based on Viking orbiter images.

- Looking for Salts on Mars

In this observation, chlorides have a bright appearance and are covered by other dark materials.

- Fissure near Cerberus Fossae with Tectonic Morphologies

The linearity of the volcanic vent in this observation, along with evidence of lava flow from the vent, suggests control by combined volcano-tectonic processes.
