Colin Dundas, Research scientist, writes on planetary science hot topic slope lineae.

Colin Dundas, a Research scientist at the Astrogeology Science Center recently had a paper published on February 3, in the scientific journal Icarus, entitled "An aeolian grainflow model for Martian Recurring Slope Lineae”.

Martian Recurring Slope Lineae are a hot topic in planetary science that is often the subject of debate and is of interest because these streaks were originally interpreted as evidence for liquid water on Mars. However, as more data become available this interpretation has been questioned. Scientific research aims to answer whether these streaks are caused by salty water flows or flows of dry sand and dust.

New or additional information regarding research on the subject is published as it becomes available.

Colin Dundas studies planetary geomorphology and surface processes using spacecraft imagery and topography data as well as numerical modeling, with a particular focus on active processes and change detection. He is a Co-Investigator and Science Theme Lead for Mass Wasting on the HiRISE camera team.
