Mars helicopter borked, broken, an ex-helicopter, now abandoned and alone

Space fans prepare yourselves, for I have some sad news: NASA's Mars-based helicopter, Ingenuity, has flown its last, thanks to a broken rotor blade. It is now an ex-helicopter, or if you prefer, the little space helicopter that no longer could. Pour one out for a true original, and give mad respect to the first aircraft on another planet that shall take to the skies no more.

After completing its 72nd flight on the Martian surface, NASA scientists reviewing images from Ingenuity's onboard camera made the sad discovery that one or more of its rotor blades were damaged (via Gizmodo) and made the decision that the helicopter will no longer be able to fly. 

This marks the end of a remarkably tough little aircraft that was originally only designed to perform five test flights, but now is consigned to the lonely Martian graveyard of dead technology and broken dreams.

Alright, it's a bit much, I know. But Ingenuity's story is one of engineering triumph, and it's likely to go down in history as one of the more successful tests of exploratory vehicles catapulted to the red planet. 

Launched in February 2021 attached to the belly of the Perseverance Mars rover (charmingly nicknamed «Percy»), the 19-inch tall helicopter weighed in at a miniscule four pounds, and once detached from its host became the first powered and controlled aircraft to fly on another planet.

While it's tempting to think of Ingenuity as a glorified drone, the engineering challenges that needed to be overcome to allow a helicopter to fly in the thin Martian atmosphere were immense. Mars has a 95% carbon dioxide atmosphere that's only 0.6% the density of the air on Earth, which meant that Ingenuity had to be extraordinarily light and generate huge amounts of lift for its size in order to fly at all.

This was achieved by employing a twin contra-rotating rotor design and the efficient use of carbon fibre in the construction, and it was this, along with six powerful DC motors and six solar-charged Sony Li ion
