Voyager 1, which is now in the outermost layer of the heliosphere that forms the boundary between the Solar System and interstellar space, is set to be the first man-made object to leave the Solar System. It has taken the car-sized probe over 35 years to reach its current point, but at its current speed of about 3.6 AU (334,640,905 miles) per year it would take over 75,000 years to reach our nearest star, Proxima Centauri. Despite the mind-boggling distances involved, DARPA has just awarded funding to form an organization whose aim is to make human interstellar travel a reality within the next century.
