China launches Tianwen-2 to image a “quasi-moon” and outline an early-warning system for sunward-approaching dangerous asteroids
China’s CNSA launched the Tianwen-2 probe from the Xichang Satellite Launch Center on May 28, 2025, and it has already snapped its first photo of Earth’s “quasi-moon.” Separately, China has announced plans for spacecraft to detect dangerous asteroids approaching from the sunward direction—an observation gap that has long limited asteroid tracking.
