One in every of humanity’s most profitable aerial missions is not taking place anyplace close to Earth.
In early December, NASA’s experimental helicopter, Ingenuity, whirled its four-foot-long rotor blades and flew on Mars for the thirty fifth time. The area company’s four-pound chopper (it weighs simply 1.5 kilos on the smaller, much less large Crimson Planet) ascended to 46 ft above the desert flooring, its highest altitude ever — and the highest-ever flight of a powered plane on one other world.
“An all-time excessive for the #MarsHelicopter!” NASA tweeted on Dec. 6. “Ingenuity accomplished Flight 35 over the weekend and set a brand new max altitude file, hitting 46 ft (14 meters) above the Martian floor.”

Ingenuity flew for 52 seconds, reaching practically 7 miles per hour whereas touring 15 ft horizontally.
This extraterrestrial aerial mission, which remains to be a flight demo, continues to vastly exceed NASA’s expectations. “Lower than a yr in the past we didn’t even know if powered, managed flight of an plane at Mars was attainable,” Thomas Zurbuchen, the affiliate administrator of NASA’s Science Mission Directorate, stated in an announcement earlier this yr. “Now, we’re wanting ahead to Ingenuity’s involvement in [the Mars Perseverance rover’s] second science marketing campaign. Such a change of mindset in such a brief interval is solely superb, and one of the crucial historic within the annals of air and area exploration.”
Flying on Mars is not straightforward. This arid world has a profoundly skinny ambiance, with only one % the floor air stress of Earth. “This implies there are comparatively few air molecules with which Ingenuity’s two 4-foot-wide (1.2-meter-wide) rotor blades can work together to realize flight,” explains NASA.

But the experimental rotor blades catch sufficient air to repeatedly take-off, fly, and land safely with out direct human management. NASA engineers beam flight directions to the close by Perseverance rover — a car-sized exploration robotic — which then transmits the subsequent aerial mission to Ingenuity.

So long as the small, dusty helicopter holds up, Ingenuity will proceed to journey by way of Mars with Perseverance. The machines are at present exploring the dried-up delta in Mars’ Jezero Crater, a spot planetary scientists imagine as soon as hosted a lake.
“This delta is likely one of the finest places on Mars for the rover to search for indicators of previous microscopic life,” NASA stated.
