Voyager 1 left earth 33 years ago. It is just NOW about to achieve a milestone in human exploration - interstellar travel.
The craft is moving at 38,000 mph so in 68,000 years, it could be approaching the nearest star to us - Proxima Centauri (it won't because it's not going quite in that direction, but it COULD.)
Read the latest news about Voyager 1, the probe that was launched when I was a Junior in high school.
"When Voyager was launched, the space age itself was only 20 years old, so there was no basis to know that spacecraft could last so long," he told BBC News.
"We had no idea how far we would have to travel to get outside the Solar System. We now know that in roughly five years, we should be outside for the first time."
