What is China's space mission Tianwen-2?

China's Tianwen-2 mission, set to launch in late May 2025, marks the nation's first endeavor to survey and sample an asteroid, Kamo'oalewa, using 'touch-and-go' and 'anchor and attach' techniques. Following this initial phase, the probe will journey to the asteroid belt to analyze comet 311P/PANSTARRS. This decade-long mission aims to place China among the leading nations in interplanetary exploration.
