Under the method, more than 20 large antennas are being combined to form an array, so that signals can be bounced from the asteroids.
This method is to be tested in September
Chinese researchers are working on a new method to detect and track asteroids. This will help to know whether any huge piece of space rock is a threat to the Earth. In this method, more than 20 large antennae are being combined to form an array, to bounce signals from asteroids, and determine whether they can affect our planet or not. Some Chinese universities are involved in this project. The details about this were first published in the official newspaper – Science and Technology Daily of the Ministry of Science and Technology of China.
North American Aerospace Defense Command
At the time Nasa scientists generally believed that North American Aerospace Defense Command (Norad) was cataloging all man-made objects in space, but Kessler suspected there might be small debris that was slipping past the military’s radar network. And if the debris wasn’t there yet, it would be eventually, he reasoned. In a landmark paper published in 1978, he calculated that the number of trackable man-made objects orbiting Earth had increased by 13% per year from 1966 to 1976. He predicted that by about the year 2000 fragments from satellite collisions would pose a serious threat to other satellites, creating a “debris belt”. “I was shocked at the answer,” he says.
If it is successful, the antenna will be started
According to the Ministry of China, the name of this project is China Fuyan in English – Compound I, and the Beijing Institute of Technology is leading this project. The asteroids selected for signal bouncing will be present at a distance of 93 million miles (150 million kilometers) from Earth.
According to a Space.com report, two antennas under the project have been built at a site in Chongqing, southern China. They will be tested in September. If the testing is successful, then they will be started after that. The diameter of the antenna will be 82 to 98 feet.
China is also working on many more technologies
Long Teng, president of the Beijing Institute of Technology, told that this project will meet the country’s needs, which include research related to the security of the near-Earth and the manufacture of asteroids. The researcher said that this system can also be applied to track satellites and debris in Earth’s orbit.
In addition, in April, the Global Times reported that the country’s space agency was developing a new monitoring and defense system. It will be tested by intentionally crashing a spacecraft with an asteroid. Reports further say that the new mission will be launched in early 2025 to re-orbit and attack a dangerous asteroid.
