There is no dedicated infrastructure on Earth for deep space optical communications, so for the purposes of DSOC, two ground telescopes have been updated to communicate with the flight laser transceiver. NASA’s Jet Propulsion Laboratory in Southern California will host the operations team, and a high-power near-infrared laser transmitter has been integrated with the Optical Communications Telescope Laboratory at’s Table Mountain facility near Wrightwood, California.

The farther Psyche travels from our planet, the fainter the laser photon signal will become, making it increasingly challenging to decode the data. As an additional challenge, the photons will take longer to reach their destination, creating a lag of over 20 minutes at the tech demo’s farthest distance.
