Voyager sets another distance record

I don't think I own a single piece of machinery that's continued to run...without repair...for 29 years. But NASA's got one -- the Voyager I spacecraft. Voyager was launched back in 1977 and it's been heading further and further and FURTHER from Earth ever since.

It's long been the furthest man-made object from Earth, but today Voyager sets another record when it reaches a distance of 100 astronomical units (AU) from Earth. An AU is the distance from the Earth to the Sun (about 93 million miles) so that means that Voyager is now more than nine BILLION miles from Earth...so far that the Sun just looks like another star...so far that it takes nearly 14 hours for its signal to reach the Earth.

The Planetary Society's website has a nice little write-up of this extraordinary technical achievement.
