[NASA] The astronauts will test Orion Artemis II (O2O) Optical Communication System To send 4K HD video straight back to Earth from the Moon. The system will also support enhanced image, sound, channel control, and science data transmission.
Aboard Orion, the space station includes optical modules, modems and control systems. The optical unit features a four-inch telescope on a biaxial mount. The modem modulates the digital information in the laser beam for transmission back to Earth, and demodulates the data from the laser beam received from Earth. The control system interacts with the Orin’s onboard avionics system to control and direct the communications telescope.
On Earth, facilities including JPL and the White Sands complex will maintain a broadband optical communications link with Orion. Information received from Orion will be passed on to mission operatives, scientists and researchers.
NASA board Laser Communication Relay Display (LCRD) Demonstrate the benefits of optical communication. Traditionally, missions have relied on radio communications, but better technology will better serve space missions that generate and collect increasing amounts of data. Optical communication solutions can provide 10 to 100 times the bandwidth of RF systems. Other improvements may include increased link distance, higher efficiency, reduced interference, increased security, and reduced size and weight. Our brief history of optical communications demonstrates many of these advantages.
