An innovative experiment flying aboard NASA’s Psyche mission just hit its first major milestone by successfully carrying out the most distant demonstration of laser communications. The tech demo could one day help NASA missions probe deeper into space and uncover more discoveries about the origin of the universe.
Set in motion in mid-October, the Psyche spacecraft is presently on its way to provide humanity’s inaugural view of a metal asteroid situated between the orbits of Mars and Jupiter. Over the next six years, the spacecraft will cover approximately 2.2 billion miles (3.6 billion kilometers) to reach its destination, the eponymous Psyche, positioned in the outer region of the main asteroid belt.
Accompanying Psyche on this voyage is the Deep Space Optical Communications technology demonstration, known as DSOC. This technology is conducting its own mission throughout the initial two years of the journey, adding a dimension of exploration and experimentation to the overall mission.
The tech demo was designed to be the US space agency’s most distant experiment of high-bandwidth laser communications, testing the sending and receiving of data to and from Earth using an invisible near-infrared laser. The laser can send data at 10 to 100 times the speed of traditional radio wave systems NASA uses on other missions. If wholly successful over the next couple of years, this experiment could be the future basis of technology that is used to communicate with humans exploring Mars.
And DSOC recently achieved what engineers called “first light,” the feat of successfully sending and receiving its first data. An innovative experiment
The experiment beamed a laser encoded with data from far beyond the moon for the first time. The test data was sent from nearly 10 million miles (16 million kilometers) away and reached the Hale Telescope at the California Institute of Technology’s Palomar Observatory in Pasadena, California.
