Ingenuity, the helicopter of the Mars exploration mission that landed on the Mars with rover Perseverance, successfully lifted off from Mars at 3:30 pm on April 19, 2021.
It successfully lifted off from Mars, the first powered flight on an alien planet.
The entire first flight was recorded by rover Perseverance.
NASA held a press conference to provide detailed data about this historic flight.
The "Ingenuity" lifted off to a height of 3 meters, stayed in the air for 30 seconds and then landed.
At the same time, a video of the first flight of "Ingenuity" shot by "Perseverance" was released.

Due to the delay in message transmission between the Earth and Mars, the flight could be broadcast live.
NASA received the data live after nearly 3 hours.

Ingenuity is a solar-powered helicopter weighing about 1.8 kilograms.
Ingenuity was able to take a picture of its own shadow on Mars.  
This helicopter-type robot is programmed to rise straight up to a height of about 3 meters, hover above the surface of Mars for about half a minute, and finally land on four legs.

The technical difficulty of a helicopter taking off on Mars is much more difficult than that on Earth.
The air density on Mars is only 1% of that on Earth, making it difficult for helicopters to rely on air resistance to generate propulsion.
Therefore, in order to obtain sufficient air support, the blades of Ingenuity must move in reverse direction every minute.
2,400 high-speed rotations.

It is worth mentioning that in performing its fifth test flight, Ingenuity set a new milestone.
It completed its first one-way transit flight and landed at a spot 129 meters away and reached a new flight height of 10 meters.
