NASA's Voyager 1, now 25.79 billion kilometres (16.02 billion miles) from Earth, is on course to cross a symbolic milestone: a distance of one light-day, the time light takes to travel between the probe and Earth. The milestone is expected in roughly 40 days, while Voyager 2 trails at 21.58 billion kilometres. Space enthusiasts are marking the probe's continuing journey into interstellar space nearly five decades after launch.
