NASA Mars successfully tested the helicopter in the chamber with carbon dioxide
Many fans of the cosmos are eagerly awaiting the summer of 2020 - that's when the mission starts, during which the Mars 2020 and the accompanying helicopter flight to the Red Planet to find out whether there was on it ever life. Recently, NASA Space Agency announced the successful testing of the rover - the researchers believe that it is ready to self-landing on the planet, without outside interference. A week later there was another good news that says that the helicopter has proven its ability to fly in Martian conditions. Testing was performed in a special chamber with carbon dioxide.
The experiment was held at the Laboratory of NASA's Jet Propulsion near Los Angeles. Mars conditions were restored in the chamber 7, the width, 62 meters, first researchers sucked out of it all nitrogen, oxygen and other gases, and then filled with carbon dioxide - the major component of the atmosphere of Mars. To ensure low gravity, scientists used gravity discharge system - the strap on top of the helicopter, which provides power, the equivalent of two-thirds of the Earth's gravity. During the two test helicopter takeoffs rose by 5 centimeters - to make sure that the machine can fly in Martian conditions, that was enough. Previous tests have proven that the helicopter is able to withstand sudden changes in temperature, and this helped him great internal heater.
Helicopter weight of 1, 8 kilograms and a box-like shape equipped with a camera to detect interesting for the study of surfaces. When accompanied by Mars 2020 system, it will also collect data to build routes for subsequent missions. After studying its behavior, engineers can build advanced vehicles for flying to Mars, correcting any errors.
The fact that the Mars mission in 2020 will include a helicopter, it became known in May 2018. Then we published an article with a detailed explanation of how it works - Recommended reading!
