NASA’s Perseverance rover made its Martian debut this week—and strapped to its underbelly is one of NASA’s most daring scientific creations. Weighing at just four pounds (or 1.5 pounds on Mars), Ingenuity will become the first rotorcraft to explore the skies of another world.
To ensure the helicopter would be ready for its Red Planet debut, engineers at NASA’s Jet Propulsion Laboratory in Pasadena, California, developed two Ingenuity prototypes. They subjected one prototype to rigorous environmental testing to see whether it could survive chilling temperatures and vibrations associated with lift-off and landing. The other was developed specifically for flight tests, which took place in a 25-foot- diameter vacuum-sealed space simulation chamber on JPL’s campus.
Now, it’s almost showtime. Once separated from the rover, Percy’s otherworldly helo will have just 30 martian solar days (commonly called sols, which are each 24 hours, 39 minutes, and 35 seconds) to conduct a series of up to five test flights, each lasting anywhere from 30 to 90 seconds. The helicopter’s most ambitious hops, nearly all of which will be choreographed by Ingenuity itself, could take it as high as a single-story building and far as 1,000 feet.
