NASA's Deep Space Optical Communications (DSOC) technology has completed its two-year demonstration aboard the Psyche spacecraft, surpassing project expectations by reliably transmitting laser-encoded data from distances comparable to Mars. The system successfully carried out 65 passes, including a final signal exchange at 218 million miles.

"NASA is setting America on the path to Mars, and advancing laser communications technologies brings us one step closer to streaming high-definition video and delivering valuable data from the Martian surface faster than ever before," said acting NASA Administrator Sean Duffy.

Within a month of Psyche's 2023 launch, DSOC established a laser link with its onboard optical terminal, proving data transmission could be sustained across interplanetary dist
