NASA laser communication system transmits data across 218 million miles

NASA's laser communication system successfully transmitted data across 218 million miles, demonstrating a promising new technology for deep space missions. The Deep Space Optical Communications (DSOC) experiment, aboard the Psyche mission, completed its final test, exceeding goals by exchanging laser signals over vast distances. This technology could enable faster data transfer from future Mars missions. DSOC achieved 65 successful passes, downlinking 13.6 terabits of data, including an ultra-high-definition video streamed from 19 million miles away. The system uses laser light pulses instead of traditional radio frequencies.
