Moon-to-Earth laser link brings Artemis 2 data home in HD

Space.com reports that NASA’s Artemis 2 mission used the Orion Artemis 2 Optical Communications System (O2O) to beam back high‑definition video and images from the Moon via infrared laser links, delivering data at up to about 260 MB/s to ground stations and downlinking roughly half a terabyte over the 10‑day flight, enabling near real‑time public coverage and setting the stage for higher‑bandwidth communications on future Artemis missions.
