During the Artemis II mission, NASA successfully demonstrated the use of laser (optical) communications at lunar distances, providing high-definition video, images, and data transfer between the Orion spacecraft and Earth. The optical terminal, mounted on Orion's exterior, allowed the crew to send and receive 484 gigabytes of data, equivalent to about 100 HD movies, dramatically exceeding the capacity of traditional radio frequency systems. The system transmitted real-time science data, voice communications, and photos, supporting faster scientific decision-making and enabling the public to experience the mission with unprecedented clarity. Ground stations at NASA's Jet Propulsion Laboratory, White Sands Complex, and the Australian National University were instrumental in receiving these signals, proving that commercial off-the-shelf components can effectively support lunar optical communications. The optical system achieved multiple downlinks at 260 megabits per second, far surpassing
