The flight occurred very early this morning, and NASA received telemetry confirming that the ‘Ingenuity’ helicopter it sent to Mars with its Perseverance rover. This is a major achievement, in no small part because the atmosphere is so thin on Mars that creating a rotor-powered craft like Ingenuity that can actually use it to produce lift is a huge challenge. > This first flight of Ingenuity was an autonomous remote flight, with crews on Earth controlling it just by sending commands through at the appropriate times to signal when it should begin and end its 40-second trip through the Martian ‘air.’ While that might seem like a really short trip, it provides immense value in terms of the data collected by the helicopter during the flight. Ingenuity actually has a much more powerful processor on board than even the Perseverance rover itself, and that’s because it intends to gather massive amounts of data about what happens during its flight test so that it can transmit that to the rover, which then leapfrogs the information back to Earth.
