At 18:52 Beijing time on April 19, NASA announced that,
This is the first time that human beings have completed power flight in the atmosphere outside the earth.
The first flight speed of the rotor blade reached 2500 RPM from 0 in 12 seconds, and reached an altitude of 3 meters in 6 seconds, while hovering in the air for 30 seconds.
It is worth mentioning that because the air on Mars is very thin, the rotation speed of the rotor blades of a Mars helicopter must be much faster than that on earth.
You know, the main rotor speed of helicopters on earth is about 300 rpm,
It is worth noting that in memory of the significance of this flight,
As the first Mars helicopter in human history, it opens up a new perspective to observe Mars.
