Deviated from orbit in 8 minutes, "one arrow and two stars" declared a failure

According to British media reports, the National Aeronautics and Space Administration NASA let helicopters fly on Mars. This feat, which was directly evaluated by the media as a "Wright Brothers moment", will bring revolutionary changes to space exploration.

NASA said the project cost as much as 61 million pounds, and the battery-powered "Wit" Mars rover successfully rose to 3 meters above the surface of Mars, hovered for 30 seconds, and then landed after spinning. It is worth mentioning that this is the first time to achieve steerable powered flight on another planet, 170 million miles away, after the success, the Mars Helicopter project team at NASA's Jet Propulsion Laboratory cheered.

The report also said that this mission was difficult. The gravity of Mars is much smaller than that of the earth, the atmosphere is extremely thin, and the surface pressure is only 1% of that of the earth. The researchers can only estimate the wind speed of the Martian mountains, and the rotor blades will reach 2400 revolutions per minute. Leaving this helicopter in the air is 5 times the speed necessary on Earth. But no matter how difficult it was, the final plan was successfully completed.

In recent years, with the advancement of science and technology, human beings have begun to turn their attention to outer space, and have a great interest in the unknown sky. In order to explore a more secret universe, all countries are sparing no effort to develop aerospace technology, especially my country's Tiangong, Chang'e, and Long March. The successful launch of the world has made the world jealous, but not every country can have space technology like China and the United States.

Europe is a typical example. Back then, the European Ariane Company launched the "Vega" carrier rocket. After a loud bang, the Vega took off. Only 8 minutes later, bad news came that the Vega deviated from the orbit and lost contact. The satellite disappeared, which also marked the complete failure of the European "one arrow and two satellites" plan.

It is understood that the two satellites carried by "Vega" were originally used to observe natural disasters. After the two satellites were silent, it means that the 2.45 billion yuan invested by them was lost.

As a country that wants to develop in the aerospace industry, the experience of "Vega" reminds us that the reason for the failure of European countries is that they indulge in the advantages of the past and are unwilling to break their inherent thinking. When developing, we must have the courage to innovate.

It is worth mentioning that Russia has officially announced that it will withdraw from the project after the end of the space station operation contract in 2024, while my country's space station will be completed in 2022. In other words, after 2024, China will have the only space station in the world, which is Something we are very proud of.
