China News Service, April 19, reported that the National Aeronautics and Space Administration (NASA) announced that the first flight of the first unmanned helicopter on Mars, the Ingenuity helicopter, will take place on April 19.

Foreign media believe that the first flight of the "Witty" helicopter is as significant as the Wright brothers' first test flight of a man-made aircraft on the earth, and it will bring a new "weapon" for mankind to explore the universe.

On April 4, 2021 local time, an original NASA helicopter landed on the surface of Mars before flying.

  The source said: "NASA predicts that the first flight of an unmanned helicopter to Mars will be held no earlier than April 19, at about 3:30 EDT."

Data related to the first flight of the helicopter will be sent back to Earth a few hours after the end of the flight.

  According to previous reports, the first flight of the "Witty" helicopter has been postponed many times.

  According to reports, the flight was a real challenge because the air on Mars is very thin-less than one percent of the pressure of the Earth's atmosphere.

This means that, in order to fly, the rotation speed of the rotor blades of a Martian helicopter must be much faster than that of a helicopter on Earth.

  NASA said this "unprecedented" helicopter operation is very dangerous, but said it can obtain valuable data about Martian conditions.

  The "Wit" helicopter carrying the "Perseverance" Mars rover successfully landed on the surface of Mars in February this year.

According to NASA's plan, the Mars rover will monitor the flight of the helicopter and send the captured pictures and data back to Earth.
