How to prepare for the flight of the first space helicopter’Injinyuiti’ flying in the thin Mars sky

It has to endure minus 90 degrees without periphery protection… it needs to supply heater power and reserve flight power

On the 11th of this month (U.S. Eastern Time), NASA’s Mars Exploration Rover Perciviarence’s small helicopter,’Indigenuity’, will make its first historic flight. This is the first motorized flight attempted in Mars skies. This is an attempt to be made about two months after Percivirence arrived on Mars on February 19th.

Mars has about a third of the Earth’s gravity, but its atmospheric density is only one hundredth of the Earth’s, so the aircraft needs more power to fly. Even if the propeller is rotated, the lift is insufficient. The weight was greatly reduced to solve the problem. Only the solar panel, camera, laser altimeter, and communication equipment were loaded, and the weight was set to 1.8kg and 50cm in height. Two 1.2m long wings were mounted up and down to rotate 2537 times per minute. In this way, it is possible to ascend at a speed of 1m per second.

The energy to rotate the wing comes from the sun. However, only half of the Earth’s solar energy reaches its surface during the daytime on Mars. Also, at night, Mars falls to -90 degrees below zero, which can freeze or break electrical components. In addition to the energy to be used for flight, the energy to supply power to the internal heater is considered as a big challenge.

In this test flight, 100% of the energy was supplied through Persitivity. At present, Injinuity is suspended 13cm above the surface of Mars with 4 legs extended, hanging from the bottom of Percivience. By the 11th, Perciviarance will drop the Incognito on the surface and drop by 5m. From this point on, Indigenuity must survive in the harsh environment of Mars outside the protection of Percivience.

“It will be a big challenge for Injinity to be deployed on the surface of Mars,” said Bob Balaram, chief engineer at NASA’s Jet Propulsion Lab (JPL). Will be.”

After enduring the Martian night and ready to fly, Injinyuiti will hover over the surface of Mars for up to 30 seconds, holding it in place for up to 30 seconds. After that, a test of landing after descending is performed. Persistence captures the entire flight process from the side and transmits it to Earth. The video filmed by Injinuity is also sent to Earth.

Indigenuity’s flight begins approximately 60m from Percivirence’s landing site. It is a flat area without large rocks, and is considered suitable for Injinyuiti’s flight preparation. The artificial intelligence (AI)-based navigation camera attached to Injinuity also needs the shadow of the floor to be used to recognize the position during flight, and it was analyzed that these conditions were also satisfied.

If the flight is successful, it is expected that drones will be useful in the future for humans to explore Mars.
