There’s the mosquito-zapping laser weapon, and then NASA’s Laser Communications Relay Demonstration (LCRD), an orbiting experimental platform, that successfully helped stream 4K video from an aircraft to the ISS and then back.
Put simply, a Pilatus PC-12 aircraft transmitted the signal 22,000 miles from Earth to NASA’s Laser Communications Relay Demonstration (LCRD), which then relayed the signals to the ILLUMA-T (Integrated LCRD LEO User Modem and Amplifier Terminal) payload mounted on the International Space Station (ISS). The orbiting laboratory then sent the data back to Earth. NASA’s High-Rate Delay Tolerant Networking (HDTN), a new system developed at Glenn, helped the signal penetrate cloud coverage more effectively.

These experiments are a tremendous accomplishment. We can now build upon the success of streaming 4K HD videos to and from the space station to provide future capabilities, like HD videoconferencing, for our Artemis astronauts, which will be important for crew health and activity coordination,” said Dr. Daniel Raible, principal investigator for the HDTN project at Glenn.
