NASA’s Psyche spacecraft has fired off a stream of laser-encoded data across 218 million miles. And Earth caught it. The test, part of the Deep Space Optical Communications project, used California telescopes to aim and decode the faint beams, after earlier feats like streaming ultra-HD video from 19 million miles. With 65 test passes complete, the system points to a future where Mars missions swap radio crackle for broadband bursts of light.
