China Is Building The World’s Most Far-Reaching Radar System – For Planetary Defence

According to a report from China’s Global Times, China has begun construction on a new high-definition deep-space active observation facility to bolster planetary defense.

The country’s officials and scientists say it will help it to safeguard humanity against space rocks, and other similar programs like NASA’s DART mission.

The facility will be built in the country’s Southwest Chongqing municipality. It is codenamed China Fuyan.

The observation facility will have more than 20 antennas, each of which will have a diameter of between 25 and 30 meters. These will work together at the same time to make high-definition observations of asteroids within 150 million kilometers of Earth. According to the Global Times, this will make it the world’s most far-reaching radar system.

In a statement to the Global Times, Long Teng, President of the Beijing Institute of Technology, said the construction of the China Fuyan facility will enhance the country’s near-Earth defense and space sensing capabilities and will also help it study potentially habitable exoplanets and asteroid formation.

Fuyan’s construction will begin with four 16-meter-diameter radars designed to verify the feasibility of the facility. According to the report, it will be the first deep-space radar with the capability to carry out 3D imaging and dynamic monitoring as well as active observation of space objects throughout the inner solar system.

China is also working on developing an asteroid deflection system similar to NASA’s Double Asteroid Redirection Test (DART) mission, which launched in November 2021.

China’s space agency, the China National Space Administration (CNSA), provided the first on-site evidence of water from the Moon’s surface earlier this year. It also recently announced it is developing a nuclear reactor for the Moon that it claims to be one hundred times more powerful than NASA’s similar in-development model.
