Last month, on October 13, SpaceX successfully launched NASA’s Psyche spacecraft from Launch Complex 39A at Kennedy Space Center in Florida. The spacecraft was propelled by SpaceX’s most powerful operational rocket – Falcon Heavy – which features an impressive 27 Merlin engines that generate more than 5 million pounds of thrust.
The NASA spacecraft is set to explore the intriguing metal-rich asteroid named ‘Psyche,’ which orbits the Sun between Jupiter and Mars. The primary objective of this mission is to study the exposed nickel-iron core of this early planetesimal, providing valuable insights into the fundamental building blocks of our solar system. In addition to its planetary exploration mission, Psyche will also demonstrate NASA’s Deep Space Optical Communications (DSOC) system, enabling high-bandwidth optical communication through vast interplanetary distances using a near-infrared laser.

NASA’s Psyche spacecraft, currently over 10 million miles away from Earth, successfully transmitted and received a laser signal as part of the first test of the DSOC system. The momentous event marks a significant leap forward in interplanetary laser communication technology and opens the door to faster and more efficient data transmission in deep space missions.
On November 14, NASA detected a laser signal fired from the DSOC instrument aboard the Psyche spacecraft, which is on its way to explore the mysterious metal asteroid. Psyche continues its journey toward the asteroid, expected to arrive in the year 2029. Upon arrival, it will initiate a 29-month survey of the enigmatic metallic world.
DSOC employs an invisible near-infrared laser to send and receive test data, offering data transmission rates 10 to 100 times faster than conventional radio wave systems used in most spacecraft today. The technology demonstration will continue for nearly two years following the Psyche mission launch, with a planned Mars flyby in 2026.
Abi Biswas, the project technologist for DSOC at NASA’s Jet Propulsion Laboratory (JPL) in Southern California, expressed the significance of the achievement, stating: “Achieving first light is a tremendous achievement. The ground systems successfully detected the deep space laser photons from DSOC’s flight transceiver aboard Psyche. And we were also able to send some data, meaning we were able to exchange ‘bits of light’ from and to deep space.”
“With successful first light, the DSOC team will now work on refining the systems that control the pointing of the downlink laser aboard the transceiver. Once achieved, the project can begin its demonstration of maintaining high-bandwidth data transmission from the transceiver to [Caltech’s] Palomar [Observatory in San Diego County] at various distances from Earth. This data takes the form of bits (the smallest units of data a computer can process) encoded in the laser’s photons – quantum particles of light,” shared Jet Propulsion Laboratory representatives.
