Engineers are confident that shutting down the LECP will give Voyager 1 about a year of breathing room. They are using the time to finalize a more ambitious energy-saving fix for both Voyagers they call “the Big Bang,” which is designed to further extend Voyager operations. The idea is to swap out a group of powered devices all at once — hence the nickname — turning some things off and replacing them with lower-power alternatives to keep the spacecraft warm enough to continue gathering science data.
Radiation and cold would have killed any electronics long before it would get to another system. And with the electronics dead, nothing would be able to tell the beacon to activate.
Is there radiation between stars? I’m sure it’s cold tho.
Plenty. Unfortunately it’s mostly the nasty damaging kind, rather than the sort that can be turned into power. It also doesn’t take much damage to add up, when you’re dealing with large millennia time scales.
The damaging kind necessarily carries enough energy to cause damage, what’s preventing it from being harvested?
Imagine you have a paper balloon setup. It randomly takes hits from a high powered rifle. In theory, you could harvest the energy. However, it’s delivered in such powerful, random bursts that capturing it is difficult.
Gamma rays punch straight through the structure of the craft. The actual energy is small (around 1/1,000,000 of a joule), but it’s so focused that it damages anything it hits. If it hits the atoms in a transistor, that transistor gets ripped up at an atomic level.
it would destroy them so when heated and energized they would not work?
