NASA’s Curiosity Rover “spots clouds shaped by gravity waves”

From this story on

“NASA’s Curiosity rover usually keeps its instruments firmly focused on Mars’s ground, zapping grit with its laser or drilling cores in bedrock. But every few days, the SUV-sized robot, like any good dreamer, shifts its sights upward to the clouds.
