Launched in 1977, the Voyager Space Probes I and II are making their merry way out of our Solar System. They are presently hitting a ‘bubble’ of charged particles put out by our sun that most astronomers consider to be the borderline between our Solar System and deep space.
Voyager Space probes are expected to still have power until about 2025. After that they will simply be drifting further into interstellar space towards nearby stars, but even at 38,000 mph it will take tens of thousands of years to get there. What shape the probe (besides electronically dead) will be in by that time is anyone’s guess
