NASA expects Voyager 1 to reach one light-day from Earth on November 18

NASA expects Voyager 1 to reach a distance of one light-day from Earth on November 18. At that distance, about 25.9 billion kilometres, a signal travelling at the speed of light would take 24 hours to reach the probe one way. NASA announced the forecast on November 10. Launched in 1977, Voyager 1 entered interstellar space in 2012. NASA says it and its twin, Voyager 2, continue to gather observations beyond the bubble formed by the Sun’s influence. NASA’s Jet Propulsion Laboratory plans to discuss both missions and the challenges of operating the probes at such distances on November 19 at 10:30 p.m. India time. NASA lists the discussion on its live programming page.
