China achieves lunar laser communication
Chinese researchers successfully tested a bidirectional laser link between Earth and the Moon over a distance of more than 400,000 kilometers. This test achieved data transfer rates of up to 1.25 Megabits per second for the uplink and 100 Megabits per second for the downlink, after a year of development to improve laser beam pointing accuracy and overcome signal strength challenges. This advancement aims to provide a high-speed method for data transmission during lunar exploration missions, especially as the volume of data from future missions is expected to increase.
