China Space Agency (CNSA) or NASA, which is more powerful?

There is no doubt that NASA is the strongest space exploration institution in the world. In the 1970s, it began to explore the solar system extensively. Voyager 1 has flown 22 billion kilometers, and its main goal is to explore Saturn, Jupiter and other celestial bodies.

In fact, China's space flight started much later than that of the United States, and the United States was not affected during World War II. After World War II, the United States rapidly promoted industrialization.1In the 1950s, the United States became an industrialized power, attracting a large number of talents, and laughing at some technical reserves in Germany, so industrialization was rapidly improved. In the 1960' s, the United States designed many sophisticated equipment that still makes people angry, including the high-altitude reconnaissance plane Blackbird and Saturn V, the only overweight rocket that has been put into manned flight so far.

On the other hand, it is the space flight of the former Soviet Union. The former Soviet Union, like the United States, digested a lot of advanced technologies due to its rapid industrialization, and began to launch earth and even moon satellites in the 1950' s. So far, the first complete moon image was taken by the detector launched by the former Soviet Union in 1959, although the resolution was very low.

Speaking of the United States, it has really engaged in many important exploration projects, and has been conducting deep space exploration since the 1970s. The decade of 1962- 1972 is the Apollo moon landing plan, which includes several sub-plans, and realized the transition from unmanned landing to manned landing. Around 1977, the United States launched Voyager 1 and 2 successively.

/kloc-in the 1980s, the United States launched the Hubble telescope, which provided us with rich images of cosmic data; Also around the 1970s, the United States launched dozens of probes to detect Venus and Mars, realizing an unmanned soft landing of Mars. So far, many probes have patrolled Mars. There is also the Apollo solar probe, which is located near the orbit of Mercury when it is closest to the sun.

It can be said that NASA has carried out the largest solar system exploration plan to date, and all these need the support of powerful deep space telemetry system, which is much more difficult than launching several satellites around the earth. What was China doing around 1970s? Two bombs and one satellite, the first satellite, Dongfanghong-1, was launched in 1970, and lost contact after completing its mission in orbit for 2 1 days.

Due to the difficulties of economic and technological development, China once suspended the launch of large rockets and used them for other purposes. Until 2 1 century, the number of exploration spacecraft in China increased, a series of manned flight tests were carried out, and all the technologies of manned flight to the space station were mastered. In 2007, China launched the first lunar probe Chang 'e-1; Deep space exploration began, and only this year did the Mars probe and Chang 'e-5, which was sampled by the moon, be launched.

It can be said that the industrialization construction cycle of China is later than that of the United States. Due to the technical blockade, space technology initially lagged behind the United States. No matter the speed of development or the breadth of space exploration, China is really inferior to the United States. It can be said that NASA's technical reserves are still very powerful. As far as space exploration technology company is concerned, NASA supports it. How many remarkable projects have space exploration technology companies had in recent years?

Of course, this is related to Musk's hype, but we can't deny that their technical foundation is really rich. Long March 9, China's heavy weapon for moon landing or exploration activities in the future, has a larger carrying capacity than Saturn V, but Saturn V was a device more than 50 years ago. The heavy rocket written by SLS in the United States is about to enter the test flight, and its carrying capacity is much stronger than Saturn V.

At present, China lags behind the United States in terms of industrialization start time, space development time, rocket capability and detection breadth. To put it bluntly, many roads that China is taking now are the old roads of the United States and the Soviet Union, including the design of spacecraft and the moon landing scheme, and there are also the shadows of the United States and the Soviet Union. We can say that we are crossing the river by touching the United States and the Soviet Union. It is the most important thing to be brave after knowing shame and be able to see the gap. Not afraid of slowness, but afraid of standing differently.
