Voyager 1 is Forced to Rely on its Low Power Radio

Voyager 1 was launched waaaaaay back in 1977. I would have been 4 years old then! It’s an incredible achievement that technology that was built THAT long ago is still working. Yet here we are in 2024, Voyager 1 and 2 are getting older. Earlier this week, NASA had to turn off one of the radio transmitters on Voyager 1. This forced communication to rely upon the low-power radio. Alas technology around 50 years old does sometimes glitch and this was the result of a command to turn on a heater. The result was that Voyager 1 tripped into fault protection mode and switch communications! Oops.

NASA is Fixing its Link to Voyager 1

Voyagers 1 and 2 were, to put it simply, incredible. They were true explorers and unveiled many mysteries of the outer Solar System, revealing the outer planets in all their glory. Communication with Voyager 1 has until recently been possible, slow but possible. More recently however, it has been sending home garbled data rendering communication to all intents impossible although messages can still be sent. Engineers at NASA have narrowed the problem down to an onboard computer, the Flight Data System (FDS). A dump of the entire memory of the FDS has now been received so that engineers can attempt to troubleshoot and fix the issue.
