The biggest “eye of heaven”, which was built with a huge amount of money, once led the aerospace field, but now it is rusty!

It used to be the biggest “eye of heaven” in the world, but now it has been pulled down from the altar and become a huge garbage dump!

The development of science and technology requires a lot of human and material resources, as well as the economy. Once China was relatively backward in the field of science and technology, and a lot of technology had to rely on other countries. However, now China has been reborn, separated from pendulum control in all aspects, realized independence, and has the ability to develop on its own. It is very gratifying to see that China’s strength is becoming stronger and stronger. Today, China’s science and technology level has been at the top, and it is our joint efforts to achieve such results.

In 2003, Yang Liwei successfully entered space, opening the space age. Since then, China has made great achievements in the field of aerospace, and has also built various kinds of detectors. In addition, the success of China’s sky eye has made the whole world admire. It is the world’s largest radio telescope, especially the one to two sensitivity, which can quickly capture signals. It was officially put into use in 2016. Up to now, it has captured hundreds of pulsars and made outstanding contributions. It has made such a significant breakthrough in just three years. It used to be the biggest “eye of heaven” in the world, but now it has been pulled down from the altar and become a huge garbage dump!

In fact, before China’s Tianyan was built, the United States also had a huge telescope. It is understood that its diameter has reached 350 meters, which is no less than China’s Tianyan. Its appearance has caused a sensation in the whole world, that is, Arecibo space radio telescope. It took a long time to build. It was built in 1974 and cost a lot of money. At that time, the United States was also very proud of having such a telescope more than 30 years ago. We can see how powerful it is.

Its main function is to observe the changes of asteroids and satellites. As time goes by, the contribution of Arecibo radio telescope becomes less and less, and it has also been pulled down from the altar. Because it is fixed, it can not rotate back and forth, and what it observes is only a fixed range, which is relatively rigid. In today’s aerospace field, it can no longer play any major role. Every year, the United States maintains the Arecibo radio telescope, and the maintenance cost alone reaches millions of yuan.

As time goes on, it has become rusty and gradually forgotten. Today, it looks like a huge garbage dump, not like a great project at all. It’s not as brilliant as that day. I didn’t expect that the radio telescope, which was once a big hit, would look like this. It’s a pity. Today, China’s Tianyan is the largest telescope on the earth, and the data and information it sends back enable people to have a deeper understanding of the universe.

As long as it is used properly, China’s sky eye will not end up like the U.S. radio telescope. Any science and technology needs to be reasonably utilized to make the most of its role. It does not mean that the most expensive technology is the best. Only technologies that contribute to human society will be praised by the world. What do you think of China’s sky eye? You can leave a message for interaction.
