Tian Wen 1 successfully circled Mars. What does this mean for China's space industry?

The aerospace industry is of great significance to the development of our country. Space exploration activities have effectively promoted new scientific discoveries and technological breakthroughs, especially in national defense and high-tech industries. Many of these high-tech technologies used in space have actually served us, such as nuclear magnetic resonance, life support systems, diapers and even dehydrated vegetables in instant noodles. Improve the industrialization level of China and seize the future development opportunities.

Humans have been paying attention to Mars for a long time. Because of its red appearance and the backwardness of ancient science and technology, people often associate Mars with bad things, and some astronomical phenomena about Mars are also considered ominous. ? Mars stays in antares? The astronomical phenomenon of Mars has been recorded 23 times in the history of China, which is called "Martian astronomy" in the west? Mars myth star? . Since modern times, the invention of the telescope has made us know more about the universe. 1877 when? Mars storm? When it appeared, Italian astronomer Giovanni? Fognio? Giovanni Foginho ChaParelli discovered some canyons and grooves on the surface of Mars with a telescope.

The process of exploring Mars is very dangerous. The former Soviet Union and the United States started the Mars exploration competition in the 1960s, but it was too difficult to explore Mars. So far, many Mars exploration missions in the former Soviet Union or Russia have not even succeeded at all. Mars is about 500 million kilometers away from the earth. If all goes well, it will take about seven months to explore this distant planet. Due to the reasons of time, cost and feasibility, the Mars exploration mission needs to wait for a window period of 26 months, that is, when Mars is 44 degrees ahead of the Earth (Homan transfer orbit), the launch can reach Mars. At the same time, due to the long distance, few exploration opportunities, complicated orbit design, complicated Mars environment, insufficient rocket power and great technical difficulties, the success rate of Mars exploration missions has been below 50% for decades.

At present, only the United States has successfully explored Mars, and American probes have landed on Mars since 1975. Even the United States has experienced many failures, and it was not until 2 1 century that it began to achieve relatively stable success. Prior to this, due to financial, technical and policy reasons, China missed many windows in Mars exploration, so this window is very important for us this year, and we must not waste this launch window any more.
