Some of the earliest spaceflights have been facilitated via radio communication with Earth, but laser transmission is the modern evolution of space comms.
NASA has successfully transmitted data between Earth and two spacecraft using lasers, completing a groundbreaking experiment that could aid in future missions to other worlds.
NASA successfully completed the first two-way laser communication link between the Laser Communications Relay Demonstration (LCRD) and the Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T) aboard the International Space Station, marking a significant advancement in space c
