NASA spacecraft receive signal from depths of the solar system

Astronomers at NASA have made a crucial breakthrough for space communications by sending a signal from a staggering distance of 290 million miles.

The feat — sending a laser signal to the Psyche spacecraft, named after the Greek goddess of the soul and launched on a SpaceX rocket last year — broke the agency’s previous records and could revolutionize our exploration of the solar system.


Although Psyche’s main mission is to study an asteroid of the same name, the craft is also helping NASA experiment with testing laser communications through space.

The laser technology is part of NASA’s Deep Space Optical Communications experiment and promises to send data at speeds up to 100 times faster than current radio frequencies.

This breakthrough could pave the way for more complex and high-definition data transmission, potentially transforming future manned missions to Mars and beyond.

NASA hopes the breakthrough will enhance the prospects for future Mars missions, as well as our ability to study the solar system more generally.

The US-based agency’s administrator Bill Nelson said on social media: “This extraordinary achievement will transform the way we explore the solar system.”

The successful test shows that using lasers could prove a robust method for future space endeavors – but the precision required for laser communication presented significant challenges.

Meera Srinivasan, project operations manager at NASA’s Jet Propulsion Laboratory, explained: “The milestone is significant.

“Laser communications require a very high level of precision, and before we launched with Psyche, we didn’t know how much performance degradation we would see at our farthest distances.

“Now the techniques we use to track and point have been verified, confirming that optical communication can be a robust and transformative way to explore the solar system.”

The distance covered by the laser signal – about 460 million kilometers – is comparable to the maximum distance between Earth and Mars, highlighting the technology’s potential for future interplanetary missions.

And the agency’s achievements in laser communication have been steadily improving.

Late last year, NASA successfully transmitted data from 10 million miles away in a move hailed as a “first light” by the agency.

This was followed by a series of record-breaking transmissions as Psyche ventured further into space.

A notable milestone was the transmission of the first ultra-high-definition video from space, featuring a cat named Taters.

However, as the Psyche drifts further from Earth, data transfer rates decrease.

When Psyche was only 33 miles away, it could receive data at 267 megabits per second.

At the time of this latest record, the maximum speed had plummeted to 8.3 megabits per second.
