Voyager 1, launched in 1977, is set to break free from the final bonds of our solar system. Last August she registered a massive increases in galactic rays and a sudden drop in solar particles. The sun's magnetic sphere holds her still, but that won't last long.
The spacecraft is over 11 billion miles from earth with a power supply that should keep her running until about 2025.
What a sad day that will be when she shuts down for good.
Fairs Winds Voyager!
