NASA’s Psyche mission marks a major milestone in space exploration
NASA’s Psyche mission has reached a significant milestone in space exploration by successfully carrying out its first demonstration of laser communications. The Deep Space Optical Communications technology demonstration, or DSOC, is aimed at helping NASA missions to probe deeper into space and make more discoveries about the origin of the universe.
Launched in mid-October, Psyche is currently en route to study a metal asteroid located between the orbits of Mars and Jupiter. As the spacecraft travels about 2.2 billion miles over the next six years to reach its destination, DSOC will be carrying out its mission during the first two years of the journey.
The tech demo, described as NASA’s most distant experiment of high-bandwidth laser communications, was designed to test the sending and receiving of data to and from Earth using an invisible near-infrared laser. This laser can send data at a much faster rate than traditional radio wave systems used on other NASA missions, and if successful, it could be used to communicate with humans exploring Mars in the future.
DSOC recently achieved the feat of successfully sending and receiving its first data, a laser beam encoded from almost 10 million miles away, far exceeding the distance between the moon and Earth. Trudy Kortes, director of technology demonstrations for the Space Technology Mission Directorate at NASA, stated that this accomplishment is a critical milestone for DSOC and paves the way for higher-data-rate communications capable of sending scientific information, high-definition imagery, and streaming video in support of future missions to Mars.
The successful demonstration of DSOC’s capabilities positions it as a game-changing technology for the future of space exploration. As the Psyche spacecraft continues its journey, DSOC will serve as a testament to the advancements in space communication technology and the potential for uncovering more discoveries about the universe. The experiments will also allow the team to refine the systems used in the laser’s precision pointing accuracy.
While the laser will not send scientific data collected by the Psyche spacecraft, it will be used to send test data encoded in the laser’s photons, or quantum light particles. This new technique of optical communication could revolutionize the way NASA sends and receives data from its missions across deep space, leading to more data and more discoveries.
As the mission continues, the DSOC team will be monitoring the time it takes for the laser messages to travel across space as the spacecraft moves and Earth rotates. The Psyche spacecraft is also preparing for its primary mission, which involves powering on propulsion systems and testing scientific instruments in preparation for studying the asteroid when it arrives in July 2029.
The innovative experiment, along with the ongoing mission of the Psyche spacecraft, has set significant precedents in space exploration, marking a new chapter of technological advancement in the study of the universe.
