Quote from: Fishy on April 23, 2024, 01:43:50 PMVoyager-1 sends readable data again from deep space https://www.bbc.co.uk/news/science-environment-68881369

"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.

Is it using that solar power to get the on board computers, transmitters etc to work?

Edit - Google was able to answer that pretty definitively...

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.

Delighted with how well Bardet performed.  Hopefully he'll have a decent season; could well be his last

VAR is supposed to reduce human error.  In fact it has put additional humans into the chain thereby increasing human error!

Wicked Little Letters, funny but was expecting more. Jessie Buckley was excellent though

Got into alternate hell and had to choose between 2 words for my last guess. Luckily I chose the right one.

She's been doing well recently, seems to be over her battle with injury

Never liked The Magic Bus but Who are you and I Can See For Miles are fine tunes that i forgot to mention.

I recognise the titles but can't say I'm overly familiar with the others

I'll be interested in this. Always liked their well known stuff Substitute, My Gen, Pinball, Baba, Won't Get Fooled even You better.

Shout out to The Seeker too, which I only got to know when Rush covered it.

But whenever I delved below the fine icing I was distinctly unimpressed with the cake. Perhaps this will cause me to try again
