2026年8月26日，地月空间激光通信试验任务在北京取得进展 1。经过一年多的在轨测试，中国科研团队成功构建超过40万公里的地月双向激光链路，首次在轨验证地月高速激光通信能力 1。这标志着中国空间激光通信从近地轨道迈入地月空间 1。
此次任务由“地月空间DRO（远距离逆行轨道）探索研究”组织实施，由中国科学院空间应用工程与技术中心牵头 1。中国科学院空间应用工程与技术中心联合之江实验室研制DRO-A卫星激光通信试验载荷，联合中国科学院云南天文台和中国科学院上海微系统与信息技术研究所研制建设地面激光通信系统 1。该链路初步实现上行1.25兆比特每秒（Mbps）和下行100Mbps的通信速率 1。8K月面高清图像采用百Mbps级激光通信传输时间缩短至约12秒 1。
On August 26, 2026, in Beijing, a Chinese research team announced the successful establishment of a two-way laser link between the Earth and the Moon spanning over 400,000 kilometers, achieving the first in-orbit verification of high-speed laser communication in the Earth-Moon space 1. This milestone signifies that China's space laser communication has transitioned from low Earth orbit to the Earth-Moon space 1. The mission, which involved more than a year of in-orbit testing, was organized and implemented under the Earth-Moon Space Distant Retrograde Orbit (DRO) Exploration Research program 1.
The project was led by the Technology and Engineering Center for Space Utilization of the Chinese Academy of Sciences 1. Zhejiang Lab collaborated on the development of the DRO-A satellite laser communication experimental payload, while the Yunnan Observatories and the Shanghai Institute of Microsystem and Information Technology of the Chinese Academy of Sciences jointly developed and constructed the ground laser communication system 1. In terms of performance, the link initially achieved an uplink communication rate of 1.25 Mbps and a downlink rate of 100 Mbps 1. Benefiting from this 100 Mbps-level laser communication capability, the transmission time for 8K high-definition lunar surface images was reduced to approximately 12 seconds 1.
