NASA’s Ingenuity Helikopter ist für historischen Marsflug bereit

By Jordi Bou

April 8, 2021 - NASA Ingenieure planen ein Experiment mit einem Miniatur-Helikopter, der knapp über der Marsoberfläche fliegen soll. Wenn das Experiment von Erfolg gekrönt ist, wäre es das erste, mit Motor angetriebene Fluggerät, das sich auf einem anderen Planeten kontrolliert bewegt.

The little helicopter, called Ingenuity, was carried to the Red Planet by the Perseverance rover which made its dramatic landing in Jezero Crater in February.

To celebrate Ingenuity’s pioneering mission, the mission team affixed a tiny swatch of fabric from the Wright Brothers’ plane, Flyer 1, which opened the era of powered flight on Earth in 1903, underneath its solar panel.

The 1.8kg, twin-rotor aircraft will attempt a series of short hops in Mars' rarefied air. The tiny chopper, no bigger than a chihuahua dog, has to be extremely light to achieve lift in the thin atmosphere.

The flight will take place in a flat and relatively hazard-free 10 sq-metre (33sq ft) area in Jezero that engineers have nicknamed the “airfield”.

Deploying the little chopper from Perseverance’s belly onto the red dirt is a complex process that will unfold over six days. If all goes to plan, Ingenuity will then gear up for its giant leap for robotkind. During its pioneering first flight, the chopper will rise to an altitude of 3m (10ft), hover for a maximum of 30 seconds and return to land on its four springy legs.

Ingenuity features four specially made carbon-fibre blades, arranged into two 1m-long rotors that spin in opposite directions at around 2,400 revolutions per minute – many times faster than blades turn on a regular passenger helicopter.

Perseverance will endeavour to record everything on camera.

If everything goes well, the four subsequent flights will get more complex.
