NASA has announced that its Voyager 1 probe will soon become humanity’s first object to travel one light-day from Earth. On Wednesday, the robotic space probe will hit the milestone of travelling at least 16 billion miles since its launch in 1977, a distance equal to one light-day, or how far light can travel in 24 hours. The probe completed its Saturn flyby in 1980, the end of its primary planetary mission, and is currently travelling at roughly 36,000 miles per hour (58km/h) in interstellar space, the vast gap between stars. NASA expects it to take 18,000 years to travel a full light-year, and double that before it nears another star. Plutonium-powered Voyager 1 was launched shortly before another probe, Voyager 2.
