Mars helicopter 'Ingenuity' is steadily preparing for 'the first powered flight on a planet other than Earth in human history'
The first helicopter 'Ingenuity ' to test ' powered flight on a planet other than Earth ' in human history will land on Mars on February 19, 2021 with the Mars rover '

The plan to 'fly a small helicopter on Mars' was announced in May 2018.

The helicopter, dubbed 'Ingenuity,' was launched with the spacecraft Perseverance from Cape Canaveral Air Force Station in Florida on July 30, 2020 toward Mars on February 19, 2021. Landed on Mars.

Ingenuity will begin its flight mission over 30 Mars solar days within 90 days of Perseverance's landing on Mars. On February 22, 2020, Ingenuity sent a signal to NASA's control room informing them that they had activated a heater to keep their electronics running.
Mars has about one-third the gravity of the Earth, but atmospheric pressure is only about 1% of the Earth. Therefore, Ingenuity is a helicopter that flies using rotary wings (rotor) like the earth, but it is difficult to fly a helicopter like on the earth.
To fly in the very thin atmosphere of Mars, the Ingenuity rotor is constructed with two wings of approximately 1.2 meters rotating in opposite directions at 40 revolutions per second. In addition, the aircraft weight of Ingenuity is only 1.8 kg.
When installed in Perseverance, the Ingenuity is folded as shown in the image below.
Ingenuity is powered by electricity and is equipped with a lithium-ion battery that is charged by a solar panel. The average power during flight is 350W, and it is possible to fly 90 seconds per Mars sun per day. Nominally, Ingenuity has a maximum flight altitude of about 5 meters and a range of 300 meters.
Ingenuity is fully autonomous, as it takes an average of less than 30 minutes to make a round trip between Mars and Earth. To achieve this, Ingenuity is equipped with Linux and the open source flight software framework 'fprime (F')'.

If the Ingenuity experiment is successful, we can expect future topographical surveys and sample collection in areas that cannot be explored by ground probes, such as cliffs, ice caps, and volcanoes.
As of February 27, 2021, Perseverance has successfully updated the software using the interplanetary network.
And with this interplanetary software update, the code I wrote was finally loaded onto my Perseverance computer! !! !! !! !! !! ????

And with the interplanetary software update, the code I wrote should now be loaded on Perseverance's computer! ????
