Chinese scientists are building more than 20 large radar antennae to track asteroids potentially threatening Earth.
China Fuyan (or 'composite eye') which is the name given to the project is being conducted by the Beijing Institute of Technology, Beijing, China.
It is hoped that by using this array, we will be able to capture images, track, and assess the likelihood of an asteroid impacting Earth by reflecting signals off asteroids within 93 million miles (150 million kilometers) of the Earth, roughly about as far away as the sun is from us.
There are already two antennas being built at an existing location in Chongqing, which is located in the South of China.
Earlier this week, the Chinese-language publication Science and Technology Daily published an article stating that the pair may be tested and operational in September, which is when the news broke.
More than 20 radar antennas will be included in the completed system, each of which will measure 82 to 98 feet (25 to 30 meters) in diameter.
News reports in the Chinese media claim that the system will be the world's farthest-reaching radar system, but when it comes to details about the system, such as the wavelengths at which it will operate, little is known about the project.
As the Chinese National Space Administration announced in April, it is working on a plan to develop a planetary defense system that would track near-Earth objects and launch an asteroid-deflection test mission shortly.
During an interview with Beijing news outlet Global Times, Beijing Institute of Technology president Long Teng said that the Beijing Institute of Technology project will be able to meet China's needs for space exploration and near-Earth defenses as well as pursue advanced studies on asteroids' formation.
This system may also be useful for tracking satellites or debris in orbit around the Earth since it could be used to track them.
