1 Because, the development of aerospace industry to this day, its significance has long gone beyond scientific exploration. Just as facing the sea, our minds have become broad-minded, and in the face of the infinite space, human beings' horizons have been greatly expanded, and there is more reason to think about their own homeland and their own destiny.
Sex. 2' is to tell us about China's history of aerospace.
3.Because many countries have not yet fully explored the truth in space.
4.Connecting the previous and the next, and undertaking the difficult exploration of space above. Thus, it leads to the admiration for the spirit of lunar exploration in the following.
-
1. Why is it said that "the launch of the 'Chang'e-1' satellite leads the progress of human space exploration"?
A: Aerospace experts from Japan, Germany, Italy and other countries appeared on the viewing platform at China's Chang'e-1 satellite launch site.
2. Judging from the text, why does the author review the history of the development of the aerospace industry?
Mount Everest is there, space is there, the moon and other planets are there, and the hope of human knowledge and progress is there.
3. Why does the article quote Luan En, the commander-in-chief of the lunar exploration project, as saying, "In space exploration, no one knows how far we can go and how fast we can go." "This sentence?

China, the United States, Russia, France, Great Britain.
A space shuttle (also known as a space shuttle or space shuttle) is a reusable spacecraft that travels between space and the ground, combining the properties of an airplane and a spacecraft. It can not only send satellites and other spacecraft into space on behalf of launch vehicles, but also operate in orbit like a manned spacecraft, and glide and land in the atmosphere like an airplane. The space shuttle provided a very good tool for human beings to enter and exit space freely, and it greatly reduced the cost of space activities, which was an important milestone in the history of spaceflight.
-
Now the countries that are able to explore space are the United States, Russia, China.
The United States is now a leader in the space club, with great achievements in space exploration.
Fifty years after space exploration began, NASA astronauts orbited the Earth, walked on the moon, flew the first space shuttle and built the International Space Station.
And Russian space technology was built mainly on the basis of the USSR and developed rapidly. Russia carried out 31 space launches in 2010, and the launches are generally progressing smoothly. Putin said that Russia will continue to increase the number of space launches and comprehensively develop its presence in the global space market.
The history of China's aerospace industry began in February 1956, when the famous scientist Qian Xuesen put forward the "Opinions on the Establishment of China's National Defense Aviation Industry" to **. In April 1956, the Aviation Industry Commission of the People's Republic of China was established to lead China's aviation and rocket undertakings in a unified manner. As the director, Huang Kecheng and Zhao Erlu served as the deputy directors, and the establishment of the Aviation Industry Committee marked the beginning of China's aerospace industry.
At 18:05 on October 24, 2007, with the successful flight of Chang'e-1 to the moon, China's space technology has taken a step closer.
Sky Introduction: Space refers to the cosmic space outside the Earth's atmosphere, the entire space outside the atmospheric space. Physicists divide the atmosphere into 5 layers:
The troposphere (sea level up to 9 km), the stratosphere (9 45 km), the mesosphere (45 80 km), the thermosphere (ionosphere, 80,400 km) and the outer atmosphere (ionosphere, above 400 km). About 3.4 percent of the atmosphere above the Earth is in the troposphere and 97 per cent below the stratosphere, the outer edge of which is the maximum limit for aircraft to fly with air support.

Russia has military reserves, such as a lot of ** equipment and technical reserves of the Soviet Union back then, and Russia's nuclear warheads are the most countries in the world, just comparing Britain and Russia with each other, I don't think Britain is Russia's opponent! Because Britain is now largely dependent on the United States militarily!
-
Russia's military power is much stronger than that of Britain!
-
Only China, the United States, and Russia have the ability to land on the moon, and the moon landing is a very complex and very large high-tech project in aerospace technology, and the investment is also huge, and ordinary countries simply do not have the ability to do so.
-
At present, there are only three countries in the world that have the ability to go to the moon, and that is China, the United States, and Russia.
-
At the moment, only the United States has successfully landed on the moon. Russia and China are almost, but soon. India has been working on it lately.
-
China, the United States and Russia should all have capabilities, but the cost of the plan is a bit imperfect, so it is not listed.
-
Only three countries have successfully landed on the moon, so how difficult is it to have a soft landing on the moon.
-
It should be the three countries of the United States, Russia and China, and the key is to see if they need to go to the moon.
-
The countries that have landed on the moon so far are the United States, the former Soviet Union and China.
-
It should be the United States, Russia, and China.

In my opinion, the current United States and Russia are not competing for hegemony, but at best they are just a great power competition in the context of global multipolarization. During the Cold War, both the United States and Russia wanted to put the other side to death, so that the United States would be flawless and had no time to contain us, a poor big country in the East, so we had a relatively peaceful environment, and reform and opening up were developing rapidly. After the drastic changes in Eastern Europe, the United States was just about to point the spearhead at China and wanted to provoke confrontation with China by bombing the embassy of the Federal Republic of Yugoslavia.
Uncle bin Laden did us a favor again, and the United States has been waging a war on terror for more than eight years, and this war on terror has really caused a great setback to the US military in the past few years, and at the same time has given China ten years of rapid development. And now that the war on terror is far from over, the United States has to admit that a strong, tough Russia is back ......Therefore, from my one-sided point of view, I hope that the competition between them will become more intense, so that China can maintain stable and rapid development for another few decades, and truly become a superpower on a par with the United States!
-
Personal opinion.
From now on, Russia is not competing with the United States for hegemony, but not steaming steamed buns! The United States is aggressively knocking on the western door of Russia again. Compressing Russia's strategic space, Russia could not bear it anymore and gave rise to military confrontations, including the earlier resumption of bomber cruises, the Russian-Georgian war, etc.
They are not fighting on the same level. Russia is invincible by land, sea and air, and neither is it in space, so it is not qualified to fight.
China can only wait and see what happens, and it is only good to work hard to develop itself. It is not a short-term matter for the United States to pick Russia off the horse. China is neutral at this stage, and we can take advantage of Russia's lack of money, and we will buy its military technology and strengthen ourselves at a low price, and then solve our TW problem.
Because you neutralized Russia, you want to win us over, and this is how Ah San travels between Russia and the United States to strengthen his strength. In the later stage, in order to prevent the United States from meddling in our own problems, it is estimated that we will make our position clear. But the later stage I'm talking about is when China's economic strength, military strength, and international influence reach a certain level and have that qualification.

Because of the hegemony between the United States and Russia, and China as an important player in it, it is natural that both of the above parties want to win over China, which makes China gain double benefits. For example, Russia, although it has sold a lot of ** to China, but it is still quite wary of China, and has never sold advanced **, they are not used**, but recently Russia suddenly discussed with China to buy the latest production of Su-35 in Russia, you must know that Su-35 is Russia's latest production of heavy fighters, and the combat effectiveness can be imagined; The United States, on the other hand, is fighting for the Diaoyu Islands with great fanfare in China and its watchdog Japan, but the United States has unexpectedly "calmed down" and allowed China to buy advanced American technological products, which was unthinkable before. Both the United States and Russia are trying their best to win over China, and China can take advantage of the fisherman's profits.
-
In the confrontation between the United States and Russia, China's tendencies are bound to be decisive; Of course, China will not clearly favor one side or the other, because that would minimize China's interests.
As for China's politics, it will be a test of flexibility, and only when we flexibly use our political skills on the world stage can our economy and military develop to the greatest extent in this confrontation between the United States and Russia, and our domestic social problems will also be able to avoid external interference.
-
It doesn't have any effect, it's good for China. Both want to win over China. At present, none of the Chinese team has any support.
In the past, China was pro-Soviet. Now it's not pro-Russian. Sino-Russian relations are not as good as you think.
China can now develop itself more in the cracks.
-
How can there be a US-Russia hegemony now? At present, the main imaginary enemy of the United States is China, and the United States is now trying to find ways to improve relations between the United States and Russia. Russia now has no strength to fight, and now the only way to balance the United States is through Sino-Russian strategic cooperation.
-
First of all, to illustrate one problem, the United States and Russia do not now have a situation of competing for hegemony, but Russia is reluctantly confronting the United States
-
It's nothing, we can't move forward if they don't make progress, and the more developed they are, the harder we work, not to beat others, but to keep not being beaten, and to fight back.
-
There will definitely be an impact, because China is the object of co-optation. China can't be left alone!
-
What are the reasons for the emergence of the characteristics of China's foreign relations during the period when the United States and Russia are vying for hegemony? China is the only one that has always been. Alas, it has been peaceful. Not at risk. No? Reluctance to war. Peace rose and smiled.
Yes, of course!! It will be a great threat to artificial satellites flying over the earth! There should be no threat to the ground, because the earth has a natural umbrella, the atmosphere!! >>>More
I don't understand strategy.
However, it is said that the collision was due to a miscalculation of the orbit of the American satellite, so the Russian satellite was knocked down. >>>More
2.In the absence of closed beta, if you want to play SC2, you can only use a cracking tool and a computer (AI patch). >>>More
You check to see if the key doesn't come up after pressing it.
Meituan relied on its own strength to return to the pre-liberation period.
