ESP_040776_2115_1.0xA piece of Mars: This 300×300 m (984×984 ft) scene shows bright windblown dunes or ripples arrayed in a lacy pattern (the biggest ones are about 5 m, or 16 ft, across). This is near the landing site of Ares 3, a science fiction book called “The Martian”, by Andy Weir that’s being made into a movie. I’m betting these beauties won’t make an appearance in the movie, though… (HiRISE ESP_040776_2115, NASA/JPL/Univ. of Arizona)
