"the issue was resolved by shifting the affected code to different locations in the memory of the probe's computers"
Amazing to think of people moving code around in the RAM of a computer system that's 15 billion miles away and hasn't been physically touched for 46 years, by using a very slow and weak radio link.
I started to try to imagine one billion miles as an understandable concept. I fully understand the number and what it signifies, but one thousand million miles is staggeringly difficult to absorb. Times that by fifteen and it becomes a pointless exercise of Brian energy, and to think that in cosmological terms it's not even that far away.
It's actually pretty close, despite the fact that it takes the light of the sun nearly a day to get there. If you were perched atop it with a paperback in one hand, you could probably read it by sunlight, just about. A bit like moonlight I think.
QuoteThe Voyagers travel too far from the Sun to use solar panels; instead, they were equipped with power sources called radioisotope thermoelectric generators (RTGs). These devices, used on other deep space missions, convert the heat produced from the natural radioactive decay of plutonium into electricity to power the spacecraft instruments, computers, radio and other systems.
