Human beings ask about the history of Mars, did India launch first? Spicy eyes
- In July 1965, the US Mariner 4 flew close to Mars, and 21 photos were taken from a distance of 10,000 kilometers from Mars.
- In 1972, the US Mariner 9 launched the first one. Mars satellite , long-term work around Mars;
- 1974 before the Soviet Union "Mars" 6 and "Mars" 7 probes landed on the surface of Mars, the results were not announced;
- 1976 in the United States The "pirate" Mars rover landed on Mars;
- On January 23, 2004, the European "Mars Express" first discovered frozen water in the south pole of Mars;
- Mars rover launched by India in 2013, 2014 Entered into Mars orbit, and then sent back data, but did not land on Mars;
There are many countries engaged in Mars exploration. Only the United States and the former Soviet Union have successfully landed. Among them, the U.S. Mars exploration is continuous. Therefore, the results achieved are relatively rich.
2011年中国大连兔子 once carried a Russian rocket to Mars, but the launch failed because of a Martian change of orbit.
also launched in this time window of this year from the United States. It is estimated that the launch time will be July 30. The UAE and the United States have jointly developed the "Nozomi" Mars rover, which has been launched on July 20.
The probe launched from the blue planet
China may be late, but never absent, and the technology is leading
US "New York Times" article on July 22 , The original question: China will answer the "question from heaven" Can it land on Mars?
my country’s Mars exploration mission has no one before and no one afterwards. It will land on Mars for the first time, and will also place Mars satellites.
This Mars exploration is the first mission in my country's planetary exploration phase and a brand new milestone in the field of deep space exploration. This time, our country will accomplish the three goals of orbiting, landing and patrolling in one go. This challenge is unprecedented.
’s rocket for this launch mission is 长征五号. The Chinese call it "Fat 5", with a total weight of 5 tons, which represents the power of China’s launch vehicle.
The research and development of this Mars rover belongs to an open research and development system, which unites the strengths of scientific research institutes in mainland China and Hong Kong, Macao and Taiwan. Once successful, another industrial chain will be brought up.
Can’t be happy too early, 200 days flying, there are any problems on the road
The success rate of Mars exploration is only 43%, which is extremely difficult. After the successful launch, the Tianwen-1 probe will experience a flight of more than 400 million kilometers in the next 200 days or so, and arrive within the gravitational potential field of Mars around February next year, explaining that the probe is only captured by the gravity of Mars For one chance, in order to grasp this time, the orbiter must brake urgently when approaching Mars, not sooner or later, and the window time is very short. In addition, at this time, the probe is 193 million kilometers away from the earth and the communication delay is 11 minutes. It is almost impossible to command and operate, and the probe can only land on its own.
What is the meaning of exploring Mars, why everyone is rushing to
- Mars is the closest to the earth, and The planet most similar to the earth’s environment, the study of Mars is of great significance to the earth and the origin of life;
- found the existence of water on Mars, and there is the possibility of life. According to the existing Mars exploration results, it is clearly found that there is Coasts, rivers,Traces of lakes, as well as the landforms of alluvial plains;
- Mars is of great significance as a possible spare tire for humans in the future. If you cannot put a foot in the "Martian real estate", you will lose many opportunities to make a fortune.
Summary
The launch of Tianwen this time embodies the Chinese nation’s thousands of years of yearning for space and the exploration of the unknown world, which is of far-reaching significance, but we should not be happy to fly too early. The time is 200 days. In addition to the technical level, good luck is needed for success. Congratulations on the success of Mars exploration in advance.
