On the 14th, China invited foreign diplomats and rapporteurs to discover the Mars earthquake test. The experiment, led by the Chinese National Port Authority (CNSA), took place in Hui Lai, Hebei Province, about an hour and a half north of Beijing.
This is the first time internationally for China to discover the stage of space technology. CNSA said in a statement: "This event was the first public announcement of China's mission to probe Mars and is an important step for China to conduct international exchange and co-operation with space."
The experiment involved more than 70 people from 19 countries, including major ambassadors from France, Italy and Brazil, as well as major foreign journalists such as CNN, the AP and Reuters. This major public event was held to promote China's confidence in space exploration and international cooperation in future space development.
Changsha Yiannan CNSA said in a speech: "China officially launched a Mars exploration mission in 2016, and all development work is underway." Tests for floating and avoiding obstacles for today's Mars landlords are underway. It is an important part of the process. China's first Mars exploration will begin in 2020 as planned. "
According to CASC, the chief operator of the Chinese Space Program, the simulated earthquake successfully conducted an experiment to avoid a terrestrial obstacle in an environment that reproduces the weaker gravity of Mars. The refrigerator-sized land, suspended by 36 steel cables, rose 140 meters above ground and stood 1 m high in hovering. In this process, the propellant burner can change the lowering rate independently.
Angang Rong Zhao, chief architect of the Mars Research Mission, said: "It takes seven months to reach Mars after the probe starts, and the final landing process takes about seven minutes. The final landing process is the most difficult and dangerous step in the overall mission. "The experiment proved the most difficult part of landing on Mars.
The only country that managed to land Mars was the United States.
The countries that have so far tried to capture Mars are the Soviet Union, the United States and the European Union. The councils, which first tried to land on Mars, tried to land several times, but all failed. In 1971, Soviet Mars 3 seemed to have landed successfully on Mars, but communication was lost immediately after landing.
The United States made eight successful landing attempts, beginning with Viking 1 in 1976, and currently has Curiosity Rover and Insight geological probes on the surface of Mars.
The European Union failed because of an unknown attempt to land on the Beagle 2 in 2003, and in 2016, the landlord Skaparelli attempted to land on Mars, but crashed to the surface of Mars due to a sensor altitude malfunction.
In addition, the United States, the Soviet Union, the European Union and India have been able to send probes to Mars. The Nozomi probe launched by Japan in 1998 did not reach the orbit of Mars, and China sent a small probe called Ingung No. 1 along with the Russia Phobos Grant probe in 2011, but crashed to Earth.
US, China and Europe Mars Landing Match
2020 is the year to go to Mars every two years. At this time, the United States, the European Union and China are preparing to send a landing gear to Mars, which will be launched from mid-July to early August next year.
NASA plans to send the Mars 2020 Rover to Mars as a continuation of its curiosity. Mars 2020 weighs 1050 kg and is the largest rover explorer ever. Landing at the same time as Mars arrived in February 2021, the accompanying small drone will fly on Mars' first flight.
The European Space Agency (ESA), which suffered Skiaparelli's failure to send Skiaparelli, is sending the Exomars 2020 probe back to Mars. This time, in cooperation with Russia, he is developing a lander (828kg) and a rover (320kg). Exomas 2020 is expected to land in March 2021, after Mars 2020.
The Mars probe, currently in development in China, has been temporarily named Huoxing-1 (HX-1). It consists of a landing gear and a rover, and the solar powered rover itself weighs 240 kg. It reached Mars in February 2021, but first orbited it around the satellite. The landing will try around April.
