Laser Communications Experiments Validating Technology for Space and Moon

Seeking to advance in-space communication beyond cost, security and bandwidth limitations of RF and building on Lunar Laser Communications Demonstration (LLCD, 2013-14), NASA now operating first 2-way laser relay link from Laser Communications Relay Demonstration (LCRD) orbital craft to Integrated LCRD Low Earth Orbit User Modem and Amplifier Terminal (ILLUMA-T) mounted on exposed facility of ISS Japanese Kibō module at 1.2 Gbps data rate, ~7x the average USA internet speed; Deep Space Optical Communications technology demonstration (DSOC) recently validated very deep space laser comms, sending data from JPL Psyche 16,000,000 km (~41x Earth-Moon distance) to Palomar Observatory
