The high resolution imaging science experiment (HiRISE) on NASA's Mars Reconnaissance Orbiter captured this image in the Red Planet's Hellas Planitia region. According to the University of Arizona researchers who operate the HiRISE camera for NASA's Jet Propulsion Laboratory, shapes like this "are the result of a complex story of dunes, lava, and wind." But they also note that "enterprising viewers will make the discovery that these features look conspicuously like a famous logo."
They add that it's a coincidence, but we know better.
