Chinese scientists<\/a> have reported a milestone in space laser communications, sustaining a high-speed, hours-long laser link with a satellite more than 40,000km (25,000 miles) above the Earth. The capability is seen as critical to future deep-space networks.According to the Chinese Academy of Sciences\u2019 Institute of Optics and Electronics, which led the project, researchers used a 1.8-metre (6-foot) aperture telescope in Yunnan province to lock onto a geostationary satellite<\/a> within four seconds.<\/p>\n

During the experiment, which lasted more than three hours, the laser link sustained uninterrupted data transmission at 1 gigabit per second (Gbps) in both directions, the Sichuan Observer reported on Tuesday.<\/p>\n

The research team described the result as a \u201cleading breakthrough\u201d in long-duration, real-time communication in high orbit, where the tiniest of pointing errors or shifts in the atmosphere can break the beam.<\/p>\n

Lead researcher Liu Chao said high-orbit satellite-ground communication was often unstable and brief, sometimes lasting only minutes. And while data travels quickly from satellites, signals from Earth are much slower, making real-time interaction difficult.<\/p>\n

\u201cIt\u2019s like sending someone 10 messages and getting only one reply,\u201d Liu told the Sichuan Observer. \u201cIt\u2019s hard to have an efficient conversation that way.\u201d<\/p>\n
