NASA’s Wit Mars Helicopter completed its 25th Mars flight

According to the latest report, NASA’s Wit Mars Helicopter finished its 25th Mars flight, with a cumulative flight of 5,824 meters and a total flight time of about 46.5 minutes. The single flight distance and ground speed set another record.

NASA’s Jet Propulsion Laboratory announced on April 13 that Wit’s 25th Mars flight flew 704 meters at a speed of 5.5 meters per second, and the flight time was 161.3 seconds, braking distance, and ground speed records.

According to NASA records, the longest single flight was 625 meters before, and the ground speed was up to 5 meters per second. Wisdom is the first drone sent to another planet. In February 2021, it successfully landed on the surface of Mars with the “Perseverance” rover, weighing only 1.8 kg, but the cost is as high as 8500 Ten thousand U.S. dollars. 

Moreover, it was originally planned to only attempt 5 test flights in 30 Martian days (31 Earth days), but due to its good performance, NASA extended its mission to September this year, leaving Witty as a terrain reconnaissance probe for NASA’s Perseverance the Mars Rover.

NASA has stated that the propeller blades of a helicopter on Earth rotate at an average of 400-500 revolutions per minute. Ingenuity’s blades spin at 2,500 revolutions per minute. Bobby Braun, director of the Planetary Science Division at NASA’s Jet Propulsion Laboratory, believes that if humans can conduct scientific investigations by means of aerial flight on Mars with a thin atmosphere, they can certainly be on many other planets in the solar system, such as Titan or Venus. The future of powered flight in space exploration is real and powerful.
