NASA Invites Media, Public to Join Voyager 1 One-Light Day Activities
NASA invites the public to mark Voyager 1’s milestone of traveling one light-day from Earth with a global light-wave event and a live discussion on Nov. 17–19.
NASA’s Voyager 1, launched in 1977, will reach one light-day from Earth on Nov. 18, a distance exceeding 16 billion miles. The spacecraft, the most distant human-made object, will receive light from Earth after a 24-hour delay. NASA will celebrate this milestone with two events designed to engage the public and media worldwide.
On Nov. 17, NASA invites global participation in “Shine Bright for Voyager’s Light-Day,” encouraging people to create a golden light wave after sunset. Participants can use a NASA website to flash “VGR,” Voyager’s call sign, in Morse code via smartphones or tablets, then share images or videos on social media with @NASA.
On Nov. 19 at 12 p.m. EST, NASA’s Jet Propulsion Laboratory (JPL) in Southern California will host a moderated discussion with mission members and NASA leadership. The event will cover the status of Voyager 1 and 2, their ongoing science in interstellar space, and the challenges of operating the probes over vast distances.
Media interested in attending the Nov. 19 event in person at JPL’s von Kármán Auditorium must RSVP by Nov. 16 for U.S. press or Nov. 12 for foreign nationals. Virtual participation requires RSVP two hours before the event. A NASA+ documentary preview is also planned for release in 2027 ahead of the mission’s 50th anniversary.
