In a groundbreaking feat, a deep space experiment travelling on NASA’s Psyche spacecraft has successfully transmitted data via a near-infrared laser to Earth from 16 million kilometres away!
A deep space experiment traveling on NASA’s Psyche spacecraft has just beamed a message via laser to Earth from far beyond the Moon for the first time, an achievement that could transform how spacecraft communicate.
In the farthest-ever demonstration of this type of optical communication, the Deep Space Optical Communications (DSOC) beamed a near-infrared laser encoded with test data from its position around 16 million kilometers (10 million miles) away – which is around 40 times farther than the Moon is from Earth – to the Hale Telescope at Caltech’s Palomar Observatory in California.
