These images, taken by the High Resolution Stereo Camera (HRSC) on board ESA’s Mars Express spacecraft, are Europe’s highest-resolution pictures so far of the Martian moon Phobos. http://www.esa.int/SPECIALS/Mars_Express/SEM21TVJD1E_0.html |

The best (for me) explanation I've heard for the grooves so far was highlighted by Emily over at TPS as being the result of Phobos sweeping up ejecta in chains from Martian impacts. Scroll down on the linked article to see a computer simulation which is a good match to the observed grooves.
But looking at the latest pictures, they seem to be far too straight and of regular width to be secondary crater chains - looking much more like collapse features to my untrained eye. The mystery remains.... |
