NASA receives laser signal sent from mind-blowing 226 million kilometers away

If you think 5G is good, NASA just received a laser signal message beamed from 226 million kilometers away.

Forming part of the NASA Psyche mission that aims to study a peculiar metallic asteroid, the agency decided to give a new communication system a whirl.

And it’s exceeding all of their expectations.

The new approach uses an infrared laser over the radio waves that were previously relied upon.

And the laser signal has proven to deliver information from the most distant place in history.

Putting ‘the long-distance’ in long-distance call, Psyche was 226 million kilometers (140 million miles) from Earth when the message was sent.

To put that into context: that’s 150% of the distance between the Earth and the Sun.

Previously, as was the norm, Psyche was transmitting engineering test data via radio waves through the NASA Deep Space Network from much closer.

However, the NASA mission team then made the unprecedented decision to use an alternative route: a laser signal.

The decision was made to transmit spacecraft data on 8 April over the Deep Space Optical Communication system.

While spacecraft were previously ‘just’ tens of millions of kilometers away, even from this new and almost incomprehensible distance, the data was downloadable with a maximum rate of 25 Mbps.

This laser signal method is 10 to 100 times faster than radio transmissions and massively exceeds the goal of ‘at least 1 Mbps’.

“We downlinked about 10 minutes of duplicated spacecraft data during a pass on April 8,” Meera Srinivasan, the project’s operations lead at NASA’s Jet Propulsion Laboratory (JPL), said in a statement.

“Until then, we’d been sending test and diagnostic data in our downlinks from Psyche.

“This represents a significant milestone for the project by showing how optical communications can interface with a spacecraft’s radio frequency comms system.”

The result was that images and a cat video (what else) were beamed back from deep space.

This far surpassed the reach of Earth’s culture past the lunar library.

While an overwhelming success, there are several kinks in the tech that need ironing out.

One is that optical observations are stopped by clouds – something that doesn’t affect radio comms.

“We’ve learned a great deal about how far we can push the system when we do have clear skies, although storms have interrupted operations at both Table Mountain and Palomar on occasion,” Ryan Rogalin, project receiver electronics lead at NASA JPL.

It’s hoped that these issues can be resolved in June when Psyche and its communications will be pushed even further.

It will be 2.5 times the distance Earth is from the Sun – which, by coincidence, is the furthest distance between Mars and Earth.

If successful, it could prove that a data-intensive network between Earth and Mars is possible.

Elon Musk will be happy as he plans a massive expansion of Starship to prepare for Mars missions.
