As celestial threats like asteroid 2024 YR4 capture global attention, China is emerging as a key player in planetary defense through cutting-edge technology and international collaboration. At the forefront stands Professor Zhao Haibin, whose team operates an expanding network of high-precision telescopes across the Chinese mainland to track near-Earth objects.
Eyes on the Sky
Zhao's team, dubbed 'night-watchers,' recently contributed critical data to the International Asteroid Warning Network during 2024 YR4's close approach. Their Near-Earth Object Survey Telescope in Xinjiang's Tianshan Mountains can detect asteroids as small as 50 meters from 10 million kilometers away.
Next-Generation Defense
Planetary defense strategist Tang Menghui reveals China's Space-Based Asteroid Scout Program launching in 2026: 'Our constellation of infrared satellites will identify threats years earlier than ground systems. We're developing kinetic impactors and laser deflection prototypes through the Asian Space Cooperation Organization.'
United Front for Earth
Both experts emphasize the need for global data sharing, with Zhao noting: 'Last month's joint observation campaign with Chile and Germany prevented unnecessary public alarm about 2024 YR4.' Tang adds that China will host the 2025 Planetary Defense Conference, inviting APEC members to test asteroid deflection simulations.
