The Orion Artemis II Optical Communications System (O2O) will bring laser communications to the Moon aboard NASA’s Orion spacecraft during the Artemis II mission. O2O will be capable of transmitting high-resolution images and video when astronauts return to the lunar region for the first time in over 50 years. Artemis II will be the first crewed lunar flight to demonstrate laser communications technologies, sending data to Earth with a downlink rate of up to 260 megabits per second.
