Voyager 1, the most distant human-made object from Earth, is sending back a repetitive jumble of 1s and 0s that don't make any sense.
Scientists at NASA are desperately trying to fix the glitch from 24 billion kilometers (15 billion miles) away.
The probe can still receive commands from Earth but messages to interstellar space require approximately 22.5 hours of travel.
That means it will take days before experts know if their attempts to restore the probe's nearly 50-year-old computers have worked or not.
This isn't the first time that Voyager 1 has sent back random readouts. In 2022, the probe started returning some of its data through a broken computer onboard, corrupting the outgoing messages.
Engineers at NASA managed to figure the problem out and fix it. But it took several months.
In this case, the glitch is coming from a disruption in communication between one of three computers onboard, called the probe's flight data system (FDS), and one of the probe's subsystems: the telemetry modulation unit (TMU).
This means that no science data about interstellar space is returning to Earth. What's more, engineering data describing the health and status of the probe is also a jumbled mess.
And yes, before you ask, engineers have tried turning the FDS on and off.
A team at NASA are now pouring through decades old documents on how the probe and its computers work – extremely outdated technology that has been all but forgotten.
Today, the phone in your hand can handle more than 100 billion instructions a second. The Voyager's computers can process just 8,000 a second.
The mission was really never meant to last this long. Both the Voyager 1 and Voyager 2 probes, which were launched in close succession in 1977, were mainly designed to explore Jupiter and Saturn. They are now zooming further and further away from us through interstellar space.
Putting another probe in the same spot would require decades.
If Voyager 1's outgoing data can be fixed, scientists hope it can continue until the mission's 50th birthday.
But its days are numbered. Beyond the Oort Cloud, on the distant edges of the Kuiper Belt, both probes will inevitably fall silent as the power of their generators run out of juice.

I'm thinking front line robot...technically it's a lot less lethal than what you'd expect but could be entertaining in it's own way...
Cool picture of the Merlin Airplane Engine production facility. The Merlin powered nearly the entire line of RAF fighters and smaller bombers, including the planes that won the Battle of Britain, the Hurricane and Spitfire, along with the USAAC's premier fighter, the P-51 Mustang.
The Rolls-Royce Merlin is a British liquid-cooled V-12 piston aero engine of 27-litres (1,650 cu in) capacity. Rolls-Royce designed the engine and first ran it in 1933 as a private venture. Initially known as the PV-12, it was later called Merlin following the company convention of naming its four-stroke piston aero engines after birds of prey.
After several modifications, the first production variants of the PV-12 were completed in 1936. The first operational aircraft to enter service using the Merlin were the Fairey Battle, Hawker Hurricane and Supermarine Spitfire. The Merlin remains most closely associated with the Spitfire and Hurricane, although the majority of the production run was for the four-engined Avro Lancaster heavy bomber. A series of rapidly-applied developments, brought about by wartime needs, markedly improved the engine's performance and durability. Starting at 1,000 horsepower (750 kW) for the first production models, most late war versions produced just under 1,800 horsepower (1,300 kW), and the very latest version as used in the de Havilland Hornet over 2,000 horsepower (1,500 kW).
One of the most successful aircraft engines of the World War II era, some 50 versions of the Merlin were built by Rolls-Royce in Derby, Crewe and Glasgow, as well as by Ford of Britain at their Trafford Park factory, near Manchester. A de-rated version was also the basis of the Rolls-Royce/Rover Meteor tank engine. Post-war, the Merlin was largely superseded by the Rolls-Royce Griffon for military use, with most Merlin variants being designed and built for airliners and military transport aircraft.
The Packard V-1650 was a version of the Merlin built in the United States. Production ceased in 1950 after a total of almost 150,000 engines had been delivered. Merlin engines remain in Royal Air Force service today with the Battle of Britain Memorial Flight, and power many restored aircraft in private ownership worldwide.

I'm trying to guess when that was..late 80's.....early 90's?
