NASA is calling on people across the globe to join a unique celebration as Voyager 1, the farthest human-made object, achieves a remarkable milestone: traveling one light-day away from our home planet. Launched in 1977, the venerable spacecraft is expected to reach this historic distance on Wednesday, November 18, when it will be more than 16 billion miles (25.9 billion kilometers) from Earth.
At this colossal distance, light emitted from Earth would take approximately 24 hours to reach the spacecraft, underscoring the extraordinary scale of Voyager 1's ongoing journey into deep space and its mission to explore beyond our solar system's boundaries.
Shine Bright for Voyager: A Global Tribute
To mark this significant occasion, NASA has organized two public events. The first, titled 'Shine Bright for Voyager's Light-Day,' will take place after sunset on Tuesday, November 17. The agency encourages individuals worldwide to shine lights towards the night sky, creating a symbolic wave of golden light in honor of humanity's pioneering interstellar explorer.
Participants have several options for joining in. A dedicated online tool on smartphones or tablets can be used to flash the letters V-G-R, Voyager's distinct call sign, in Morse code. Alternatively, any light source—such as a flashlight, phone light, or lantern—can be used to manually send the signal. NASA also invites participants to capture photographs and videos of their light signals and share them on social media, tagging the agency to amplify the collective tribute to Voyager 1's enduring legacy.
NASA JPL to Host Mission Discussion
The second event is scheduled for Thursday, November 19, at 12 pm EST (9 am PST). NASA's Jet Propulsion Laboratory (JPL) in Southern California will host a moderated discussion featuring key mission officials, scientists, and agency leadership. This session will delve into the current status of both Voyager 1 and its twin, Voyager 2, and highlight the invaluable scientific observations they continue to transmit from interstellar space.
The discussion will also address the complex challenges involved in operating spacecraft across such immense distances. A question-and-answer session will follow, allowing media representatives and other audience members to engage directly with the experts. Furthermore, NASA plans to offer a preview of its upcoming Voyager documentary, set for release in 2027 to coincide with the mission's 50th anniversary.
Voyager's Continuing Scientific Legacy
Both Voyager 1 and Voyager 2 were launched in 1977 to capitalize on a rare planetary alignment, enabling them to explore the outer planets. Voyager 1 made history by entering interstellar space in 2012, with Voyager 2 following suit in 2018. These iconic spacecraft continue to provide unprecedented data and observations from the region beyond the heliosphere, the protective bubble created by the Sun's particles and magnetic fields, expanding our understanding of the universe far beyond our solar system.
