Voyager 1 Reaches One Light-Day Distance From Earth
According to NASA JPL: NASA's Voyager 1 spacecraft has reached a milestone of one light-day away from Earth, traveling over 16 billion miles since its 1977 launch.
According to NASA JPL:
Launched in 1977, Voyager 1 is officially humanity's most distant space traveler. It has traveled so far that a signal from Earth now takes a full 24 hours to reach the spacecraft. Originally designed to explore the outer planets during a rare planetary alignment, the probe eventually entered interstellar space in 2012, continuing to send back valuable scientific data from beyond the sun's protective bubble.
To mark this historic milestone, NASA has organized a series of events. On November 17, people worldwide can use their smartphones to send a symbolic morse code signal of the spacecraft's call sign. Following that, NASA's Jet Propulsion Laboratory will host a live-streamed discussion with key mission members on November 19, detailing the ongoing challenges of operating the aging probes and offering a preview of a documentary planned for the mission's 50th anniversary in 2027.
