China can take lead in tackling looming space-debris crisis that threatens Earth

The space debris crisis poses an existential threat to Earth, as evidenced by a recent incident where a tiny fragment damaged China’s Shenzhou capsule, risking reentry failure. High-velocity debris (up to 10 km/s) can devastate satellites and stations, potentially triggering Kessler syndrome and collapsing low-Earth orbit ecosystems. Experts, including a University of Hong Kong scholar, urge action amid rising collisions. China is positioned to lead globally by bolstering its space station with redundancies, accelerating expansion plans, and promoting international cooperation. Hong Kong could pioneer a space sustainability hub, spotlighted at the upcoming Asia-Pacific IAU meeting in May.
