Story summary

Liu Chao, lead researcher at the Chinese Academy of Sciences, led a breakthrough by sustaining a 1 gigabit per second laser link with a satellite over 40,000 kilometers away for more than three hours.
The experiment used a 1.8-meter telescope in Yunnan province.
The lead researcher noted that traditional satellite-ground communication is often unstable and brief.
The advance is crucial for future deep-space networks and enables real-time communication.
