NASA Mars helicopter completes flight tests

Mars helicopter of the National Aeronautics and US Space Administration (NASA) has completed flight tests in accordance with the release of the Jet Propulsion Laboratory of NASA's Jet Propulsion (the JPL) on Thursday.

At the end of January 2019, all the parts that make up the model flight to Mars by NASA helicopter, the actual car is going on the red planet, were put to the test.

Weighing in at less than 1.8 kg, a demonstration project helicopter technology is currently undergoing rigorous testing process, proving it to Mars.

Most test flight model should have done with a demonstration of how it might work on Mars, including how it works for Mars, as the temperature can helicopter to survive cold temperatures on Mars.

All tests are aimed at February 2021, when the helicopter reached the surface of the Red Planet, firmly placed under the belly of the rover's Mars in 2020, according to the release.

A few months after his landing, the helicopter will be deployed and to make test flights to 90 seconds. This will be the first flight from the surface of another world, said a press release.

"In preparation for the first flight to Mars, we walked for 75 minutes flying time from the engineering model, which has been the approach of our helicopters," said Mimi Aung, Project Manager Mars helicopter Jet Propulsion Laboratory. "But this is the last test flight model was the real deal. That's our helicopter bound for Mars. We should have seen that it works as advertised. "

During a helicopter flight to the & # 39 is commonplace here on earth, flying hundreds of millions of miles in the thin atmosphere of Mars is something quite different, said the team.

Creating the necessary conditions for testing on the ground presents its own set of problems.

Aoun said the Martian atmosphere is only about one percent of Earth's density. Command test made in JPL, Space Simulator, 7,62 m in width of the vacuum chamber, which created an atmosphere similar density as Mars.

In addition, a truly simulates a flight to Mars is required to take two-thirds of the earth's gravity, because the force of Martian gravity is much weaker, said Teddy Tzanetos, a test vehicle for Mars helicopter at the Jet Propulsion Laboratory.

The command is performed via gravity unloading systems – motorized strap attached to the top of the helicopter to provide a continuous lift equivalent to two-thirds of the Earth's gravity.

Helicopter Mars will be launched as a technology demonstrator from 2020 rover rocket United Launch Alliance Atlas V in July 2020 from the station at Cape Canaveral, Florida Air Force. It is expected that reach Mars in February 2021, according to NASA.

2020 rover will carry out geological assessment of its landing on Mars, determine the population of the environment, look for signs of ancient Martian life, and evaluation of natural resources and hazards to future human explorers.

Scientists will use the instruments on board the rover to identify and collect rock and soil samples, pack them in a sealed tube, and leave them on the surface of the planet for a possible return to Earth on a future mission to Mars, according to NASA.
