"In a matter of weeks, NASA will attempt a historic first by directing a small helicopter to take flight on another planet.

Ingenuity, a four-pound helicopter, is tucked under the belly of the agency’s Perseverance rover on Mars. And it’s getting ready for its big moment. As soon as April 8, Ingenuity will attempt to fly to an altitude of three meters.

To celebrate the momentous occasion, NASA stashed a stamp-sized piece of fabric from the famous Wright aircraft under Ingenuity’s solar panel, as the helicopter’s chief engineer Bob Balaram revealed during a Tuesday briefing."
