In this image taken by the Mars Perseverance rover and made available by NASA, the Mars Ingenuity helicopter, right, flies over the surface of the planet on Friday, April 30, 2021. Ingenuity made its fourth flight Friday afternoon, traveling 872 feet (266 meter) at a height of 16 feet (5 meters) for two minutes — considerably farther and longer than before.
