NASA's researchers are surprised to find them, perhaps like everyone else, but not for the same reasons. According to a NASA blog post, the agency has encountered the same polygon-patterned rocks before, but what makes this particular patch special is that it's "dramatically abundant," stretching across a much larger area of the planet's surface than anything previously encountered. They're visible as raw images on NASA's site as Sol 4859.…
