Ancient Cracked Mud Found on Mars

NASA's Curiosity Rover has discovered a region of Mars that seems to be covered in ancient preserved mud in a classic hexagonal pattern. What makes this spot exciting is that the mud is cracked, indicating it went through several cycles of being wet and then dried out again. Areas like this can preserve microbial life, where it doesn't stay too wet or dry for very long, and could be the perfect place for life to gain a foothold on the Red Planet.
