Star Trek's Starfleet Insignia On Mars?
NASA's Mars Reconnaissance Orbiter took some very cool pictures recently. Specifically of a dune field on the Martian surface in a large crater. There, the dunes in question have formed into shapes reminiscent of the Starfleet insignia. Well, we know this isn't product placement...but if it were, that's one gigantic billboard.
NASA says, "In this image of a dune field on Mars in a large crater near Mawrth Vallis, some of the dunes appear to be in a V-shaped formation. For dune fields, the spacing of individual dunes is a function of sand supply, wind speed, and topography." See their write-up here.
