> ...increased data rates throughout the solar system with 10 to 100 times the capacity of state-of-the-art radio systems currently used by spacecraft.
.
> Ground systems: A high-power near-infrared laser transmitter at the Jet Propulsion Laboratory’s Table Mountain facility near Wrightwood, California, will uplink a modulated laser beam to the flight transceiver and demonstrate the transmission of low-rate data.
> The uplink laser will also act as a beacon for the flight transceiver to lock onto. The downlink data sent back by the DSOC transceiver on Psyche will be collected by the 200-inch (5.1-meter) Hale Telescope at Caltech’s Palomar Observatory in San Diego County, California, using a sensitive superconducting nanowire photon-counting receiver to demonstrate high-rate data transfer.
