Small, without on-board instrumentation, powered by solar energy.AND for the first time it flew just over 39” at about 10 feet in the air, becoming the first human artifact to hover on another planet.That's how it is Ingenuity, the helicopter that landed on Mars last February together with the rover Perseverance, he gave the start of aerial exploration of the red planet, 117 years after the Wright brothers' first flight.
“Although these two iconic moments in aviation history may be separated by time and 280 million kilometers of space, now they will be connected forever,” said Thomas Zurbuchen, associate administrator of the NASA for science.“In homage to Dayton's two innovative bicycle manufacturers, this first of many airports on other worlds will now be known as Wright Brothers Field.”
A flight full of unknowns
It was not at all obvious that Ingenuity would be able to fly, because there are many differences with flight conditions on Earth.First of all the density of the Martian atmosphere, extremely rarefied with only 1 percent of the surface pressure compared to our planet.This means there are relatively few air molecules for Ingenuity's two rotor blades to interact with to achieve flight.“Providing lift to propellers is extremely difficult“, explained Paolo Bellutta of NASA's Jet Propulsion Laboratory (JPL).“Having an aircraft that can lift enough electronics to have a camera is not trivial.”
