May 2025 in China

Tianwen-2 () is a Chinese asteroid sample return and comet exploration mission that launched on 28 May 2025. The China National Space Agency (CNSA) plans for the probe to return samples from 469219 Kamoʻoalewa—a near-Earth asteroid that is currently a quasi-satellite of Earth—in 2027. After the mothership drops off the sample return vessel to Earth, it is planned to rendezvous with the main-belt comet 311P/PanSTARRS and explore it with its 11 onboard instruments.
