NASA Deep Space Optical Communications Experiment Psyche Laser Message
NASA’s Deep Space Optical Communications (DSOC) experiment onboard the Psyche spacecraft used a near-infrared laser to beam a message back to Earth from 10 million miles. This DSOC experiment officially achieved “first light” in the early hours of November 14, 2023 after its flight laser transceiver targeted a powerful uplink laser beacon transmitted from the Optical Communications Telescope Laboratory at JPL’s Table Mountain Facility.



The beacon then helped the transceiver aim its downlink laser back to Palomar, while automated systems on the transceiver itself and ground stations refined its targeting. This test data also was sent simultaneously via the uplink and downlink lasers, also known as “closing the link”, a primary objective for the experiment.

Achieving first light is one of many critical DSOC milestones in the coming months, paving the way toward higher-data-rate communications capable of sending scientific information, high-definition imagery, and streaming video in support of humanity’s next giant leap: sending humans to Mars,” said Trudy Kortes, Director of Technology Demonstrations at NASA.
