They broke into applause as one of them read off a checklist of tasks Ingenuity had achieved and concluded: "Ingenuity has performed its first flight - the first flight of a powered aircraft on another planet".
A black-and-white photo taken by a downward-pointing onboard camera while the helicopter was aloft showed the distinct shadow cast by Ingenuity in the Martian sunlight onto the ground just below it.
"The Perseverance rover will provide support during flight operations, taking images, collecting environmental data, and hosting the base station that enables the helicopter to communicate with mission controllers on Earth", the agency said in a statement. The basic rules of flight are different, in other words, and Ingenuity is testing many components for the first time. Video was then downloaded and played at mission control, showing the flight from the perspective of the Mars Perseverance rover. Mars' gravity is about a third of Earth's, and the very thin atmosphere offers just 1 percent of our planet's surface-level pressure.
Though the first flight of Ingenuity only lasted only seconds and the flight was not particularly high by Earth standards, the monumental achievement of flying a powered aircraft on another planet - especially one with as thin of air and atmosphere as Mars - can not be understated.
NASA named Ingenuity's Martian airfield used by Ingenuity the Wright Brothers Field after Orville and Wilbur Wright.
