NASA’s New Deep Space Laser Communication 40 Times Bandwidth of Radio Communications
by Brian Wang from NextBigFuture.com on (#6JKKH)
In late 2023, NASA tested a new hybrid laser/radio antenna to downlink data from 20 million miles (32 million kilometers) away at a rate of 15.63 megabits per second - about 40 times faster than radio frequency communications at that distance. On Jan. 1, 2024, the antenna downlinked a team photograph that had been uploaded ...
