Theme on Mars Expanded

14 July 2016 The IAU Working Group for Planetary System Nomenclature has approved the expansion of the theme for "other features" on Mars to include using the name of a nearby crater, if no nearby albedo feature name is available. Theme expansion was necessary because in some areas of Mars all available albedo feature names have been used. To see a list of IAU-approved themes, visit the "Categories" page in the Gazetteer of Planetary Nomenclature.
