Mick Ohrberg's Journal: Voyager 2 30 years

The Voyager 2 spacecraft (part of the ongoing Voyager Mission) today celebrates 30 years of faithful service, by far surpassing the 4 years that was its inteded lifespan. Voyager 2 is today 7.8 billion miles from the sun, placing it almost as far out as the heliopause. At the speed of light that's about 12 hours away, and it's clocking about 1 million miles per day. Voyager 1, launched a couple of weeks after Voyager 2, is at 9.7 billion miles from the sun the farthest man-made object. So when are we going to get around to sending up Voyager 6?
