Development of a second phase of China’s planetary protection radar array is underway.
The “China Compound Eye” or Fuyan undertaking will create a community of radar antennae that can bounce radar indicators off distant objects to picture and monitor asteroids and decide if they may threaten Earth.
A first phase consisting of 4, 54-foot-diameter (16 meters) radars situated close to Chongqing in southwest China was completed (opens in new tab) final December. Scientists then pinged indicators off the moon to confirm the feasibility of the system and its key applied sciences.

A brand new phase is now underway to construct 25 radar antennas, every with a diameter of 98 ft (30 m). The work is predicted to be accomplished in 2025.
“After development within the second phase is accomplished, we will observe an asteroid with a diameter of solely dozens of meters 10 million kilometers [6.2 million miles] away. For instance, what it’s composed of, what’s its rotation pace and what’s the change in its orbit after its being hit. These might be noticed with the second phase below sure situations,” stated Zeng Tao, deputy director of the Radar Know-how Analysis Institute below the Beijing Institute of Know-how.
A 3rd phase will then be initiated to broaden Fuyan’s detection vary to 90 million miles (150 million km). The undertaking makes use of a number of smaller arrays to simulate a bigger aperture system to permit deep-space detection.
The China Nationwide Area Administration introduced final April that it’s engaged on a planetary protection plan that features monitoring near-Earth objects and launching an asteroid-deflection take a look at much like NASA’s DART mission within the subsequent few years, Space.com previously reported.
Different proposals for China’s asteroid monitoring capabilities embrace sending a constellation of satellites into Venus-like orbits.
