Flying on Mars presents a serious problem.
The Martian floor air density is simply about one p.c of Earth’s, making it tough for craft to provide the raise essential to fly. But NASA’s experimental Ingenuity helicopter was designed to create raise with its rotors below such distinctive situations. Utilizing a four-foot wingspan, the robotic has now flown over 50 occasions — although the area company solely anticipated it to final for 5 flights.
NASA’s car-sized Perseverance rover not too long ago captured footage of the helicopter’s complete 54th flight in early August. After Ingenuity skilled a flight anomaly, inflicting it to promptly land, NASA ran this aerial check to verify the navigation system nonetheless labored correctly — which it does.

On the far backside of the video, at about 5 seconds in, Ingenuity fires up its rotors. At 15 seconds in, the robotic takes off. It hovers 16 toes within the Martian air earlier than touching down. All 46 seconds might be watched beneath:

Perseverance captured this clear shot from 180 toes away. Together with its trusty sidekick, Ingenuity, the rover is scouring rocks and soil for biosignatures — “an object, substance, and/or sample whose origin particularly requires a organic agent,” the area company defined.
“A key goal for Perseverance’s mission on Mars is astrobiology, together with the seek for indicators of historic microbial life,” NASA wrote.

There stays zero proof that life ever existed on Mars. However primitive life could have existed in Martian caverns or maybe a lot deeper within the soil. And past Mars, within the oceans of Enceladus and Europa out in deeper area, planetary scientists suspect situations could be appropriate for all times to evolve, if not flourish.
