Story summary

NASA's Deep Space Optical Communications (DSOC) transmitted laser-encoded data from 218 million miles, improving deep space communication.
Launched in October 2023 with the Psyche spacecraft, DSOC aims to enhance data transfer for Mars and Moon missions.
It achieved record distances and data rates, streaming ultra-high-definition video at 267 megabits per second from over 19 million miles.
DSOC used a flight laser transceiver and two ground stations for transmission.
The successful demonstration paves the way for integrating optical communications into future missions.
