Alone

Today NASA announced that the space probe Voyager 1, launched in 1977, has now left our solar system, the first man-made object to do so. Originally intended to check out the moons of Jupiter and Saturn, it has kept on going, sending back data, careering into nothingness. It will continue... although by 2025 will cease sending back data and effectively 'die' as its batteries pack in. What an amazing journey. I know it's only a hunk of metal & wire & stuff but I really feel for it. Could there be anything related to mankind that has ever been more lonely?
