Another great shot of Mars' surface, taken in December 2013 by the HiRISE camera on board the Mars Reconnaissance Orbiter. Is this a fleet of star ships built by the Utopia Planitia Fleet Yards, a major starship construction facility based on Mars where Star Trek's spacecraft (like Starship Enterprise) were built? Not really... these are arc-shaped sand dunes - also called barchan dunes - formed by winds that mainly blow from one direction. A bit less exciting than huge starships, but still an interesting oddity and a real beauty in its own right! These types of dunes exist in many places on Earth too.
