The NASA Mars Helicopter is an aircraft pilot at JPL

Since the Wright brothers became the brains of Kill Devil Hills, North Carolina, 17 December, 1903, the first time has been significant milestones in the life of any vehicle designed to air travel. After all, one would be to design and make a plane by airplane on paper or on a computer. It is quite other to put all the pieces together and look at them coming to land.

Towards the end of January 2019, all the flying modules (the vehicle itself's journey to Red Planet) of NASA's Helicopter were tested.

It is no more than 4 pounds (1.8 kilograms) in length and a helicopter is a technology demonstration project that is currently going through a strict verification process that is used for Mars.

Most of the experiment going through the plane model would have to show how Mars can work, including as it is t Have a temperature like Mars. Can the helicopter survive – and work – in cold temperature, including temperature nights as low as only 130 degrees Fahrenheit (less 90 degrees Celsius)?

The whole test is scheduled for February 2021, when the helicopter reaches the surface of the Red Planet, firmly embedded under the belly of the Mars Marsh. A few months later, they are introduced and exams (up to 90 seconds long) – the first time from another surface.

“Getting ready for that first time on Mars, we've picked up over 75 minutes of flying airplane using an engineering module, hovering to the helicopter,” said MiMi Aung, project manager. for Mars Helicopter at NASA's Jet Dress Laboratory in Pasadena, California. “But this new experiment is the real thing on the aircraft model. This is our helicopter that goes to Mars. We'd have to see how he did the job. ”

Although helicopters are flying very common here on Earth, traveling hundreds of thousands of miles (kilometers) away in the Martian atmosphere is something else completely. And the creation of the right conditions for a test here has just brought its own challenges.

“Martian air is only about one per cent of the Earth's density,” said Aung. “Groundbreaking may have similar environmental pressures on Earth – if you set up your airfield 100,000 feet (30,480 meters). So you can't go somewhere and look for that. You have to do it. ”

Aung and her Mars Helicopter team made it into the JPL space model, a 25-foot (7.62-meter) chamber. First, the crew created an empty rubbing of the nitrogen, oxygen and other atmospheric gases inside the large cylinder. Instead the team eliminated Marsh's carbon dioxide, its main substance.

“Only a part of the challenge of getting a helicopter into this environment is just part of the challenge,” said Teddy Tzanetos, trial director for the Mars Helicopter at JPL. “To make a real difference to Mars's flight we need to subtract two thirds of the Earth's gravel, as Mars's size is much weaker.” T

This team carried out an pull-pull system – a motorized surgical device connected to the helicopter top to remove uninterrupted thrill equivalent to two-thirds of the Earth's gravel. Although the team took great care as the helicopter could get their first trip, they were just as anxious about how the pulling system would be away.

“The withdrawal system was perfectly played, just like our helicopter,” said Tzanetos. “We only needed two 2-inch (5-centimeter) flags to get all the data sets needed to prove that our Mars helicopter is automatically running, as designed in thin conditions similar to Mars; it was not necessary to raise it. It was a first time tour. ”

The first Mars Helicopter flight was followed by a second in the empty room the next. By uploading up to one complete minutes of flight time at a height of 2 inches (5 centimeters), over 1,500 individual pieces of carbon fiber, flight level aluminum, silicon, copper, foil and foam have proven to work with them. combined with a complete unit.

“The next time we fly, we travel on Mars,” said Aung. “By looking at our helicopter she will pass through the room, I can only help to think about the historic vehicles that have been there before. The hospitality room provided Ranger Moon missions to the Voyagers to Cassini and the Mars Mars movement was never moved. Our helicopter then brought me in mind that we are also making a bit of a history of space. ” T

JPL's Mars Helicopter project in Pasadena, California, is managing a helicopter development for NASA's Science Attainment Science Directorate in Washington.

Helicopter Mars will be launched as a technology demonstration with the Mars 2020 moving on a rocket United Launch Alliance Atlas V in July 2020 from Complex Launch Complex 41 at Cape Canaveral Air Force Station, Florida. It is expected to arrive in Mars in February 2021.

The rover 2020 carries out geological assessments on its base in Mars, deciding how suitable the environment is, detecting the characteristics of ancient Martian life, and assessing natural resources and threats to people. who are looking to the future. Scientists will use the instruments on board the flow to identify and collect examples of rock and soil, put them in tubes on the seal, and leave them on the surface of the planet to get around it. back to Earth on the future of Mars's mission.

The JPL Mars 2020 project in Pasadena, California, manages transformational development for the Science Mission Directorate at NASA Headquarters. The NASA Energy Services Program based at Kennedy Space Space Center in Florida is responsible for opening controls.
