The weather in Arabia – The spaceship “perseveres” or Perseverance (Perseverance) NASA is preparing for the most technologically exciting phase of its mission, which is to fly a helicopter to Mars!
Perseverance has landed on a roof March Last month it was Helicopter (Ingenuity) One of the mechanisms that came to the surface with it MarchThe purpose of uploading it to the Mars rover was to demonstrate that it is possible to fly on another planet.
Details of helicopter flight in the sky of Mars
NASA officials said on Tuesday that the appropriate site on the surface of Mars for the helicopter flight experience, which is located north of the area where the Perseverance ship landed, has been chosen and the site has been selected. been chosen so that the area is naturally flat and contains no hills or heights, and it should not contain a lot of rocks that could be dangerous for the helicopter when landing.
The rover passed this site to verify it, and will return there to launch the helicopter (Ingenuity), Then step back to watch the plane fly about 200 feet away, Be the first helicopter to fly on a planet other than Earth, The experiment, if successful, will provide broader opportunities to explore Mars.
The helicopter launch date will not be later than April 8, 2021.
About the helicopter (Ingenuity) Who will fly in the sky of Mars
The helicopter called “creativity” or (IngenuityIt is a small robotic plane weighing 1.8 kg, consisting of a body the size of a soft ball, with four long protruding legs and two sets of blades, so that each group rotates in the direction opposite to generate lift.
How would a helicopter fly on Mars
The helicopter is still connected inside the Perseverance craft, but once exited it will face several challenges. Great gravity equivalent to about a third of Earth’s gravity, Let it go The density of its atmosphere is only 1% of the density of the Earth’s atmosphereDuring the day, the surface of Mars receives approximately Half the amount of solar energy Who hit the ground and can Temperatures drop overnight At minus 90 degrees Celsius, it can cause the unprotected electrical components to freeze and crack.
So it must be the helicopter Small To be able to fly in the Martian environment, you must be Lightweight To be able to survive in the nights March When cold, it must also have sufficient energy to operate the internal radiators. The plane was tested under similar conditions at NASA laboratories in Southern California.
In other words, the challenge is not just the ability to fly the aircraft over a surface. March, But also in the possibility of surviving the first night on the surface of Mars without the protection of the rover which maintains its energy.
Helicopter launch in the sky of Mars
The helicopter launch will take about six Martian days (six days, four hours on Earth). at first day Martian, the team on Earth will activate a lock-breaking device and release a locking mechanism that helps hold the helicopter firmly against the vehicle’s belly when launching and landing on Mars. at the second dayA cable cutter firearm will be fired, allowing the mechanical arm that holds the aircraft to begin rotating the helicopter out of its horizontal position. Several stages stretch over the remainder of the four days, until the world has a chance to see the helicopter flying over a rooftop. March.
