I find it amazing how engineers were good at the seventies. Even more amazing is that Voyager spacecrafts were launched in 1977, and yes, they are still working! It’s really interesting also to know that they can still debug failures 14 billion kilometers away. When the last problem happened, they sent a reset command, which took 13 hours to arrive in the Voyager’s computer, and after resetting, the Voyager 2 spacecraft sent a a reply, which also took 13 hours to arrive on Earth.
Lovely
