NASA will send a helicopter to Mars as part of NASA's 2020 mission to place next-generation rover on the surface of Mars, the first time NASA has sent a helicopter into space.
According to NASA, the remote-controlled Mars helicopter is equipped with double-reverse blades, so it can move in the thin atmosphere of Mars. Its blades can rotate at nearly 3,000 rpm, about 10 times that of a conventional helicopter. It weighs about 4 pounds (1.8 kg) and its size is softball.
Mimi Aung, NASA's Jet Propulsion Laboratory's Mars Helicopter Project Manager, said: "The altitude of helicopters flying on Earth is about 40,000 feet (12,200 meters), and Mars' atmosphere is only one percent of Earth's. So when our helicopter flies to the surface of Mars, it is already equivalent to 100,000 feet (30,480 meters) on Earth."
NASA officials say that after the helicopter reaches the surface of Mars, it will be directed to a safe area and continue to wait for orders. The controller on Earth will remotely command the helicopter to perform its first automatic flight after its battery is fully charged and tested.
The idea of ​​a helicopter flying over another planet is exciting. The purpose of the helicopter is to prove the viability and practicality of the aircraft on Mars and may act as a low-altitude scout to observe hard-to-reach locations.
The Mars 2020 probe is scheduled to be launched from Cape Canaveral Air Force Base in Florida in July 2020 and arrives at Mars in February 2021. NASA said the helicopter is designed for geological research. And determine the suitability of the Martian environment.
