To mark the 40 years of the flights of the two Voyager spacecraft through the solar system and into interstellar space, NASA held an event with several of the scientists involved in the project to discuss what it has accomplished:
This segment with William Shatner is about public messages transmitted to Voyager 1:
From the caption:
On Sept. 5, 2017—the 40th anniversary of Voyager 1’s launch—NASA revealed the winning #MessageToVoyager and beamed it into space. “Message to Voyager” is a social media campaign inspired by the messages of goodwill carried on the Golden Record aboard each Voyager spacecraft.
NASA invited the public to submit short, uplifting messages to the Voyager 1 spacecraft and all that lies beyond it. These messages were a maximum of 60 characters and were tagged #MessageToVoyager. NASA tracked more than 30,000 submissions. The Voyager team together with JPL and NASA headquarters selected their 10 favorites, which were then put to a public vote. The winning message was sent into interstellar space by a command that originated from the Deep Space Network (DSN) mission control at NASA’s Jet Propulsion Laboratory with help from the original Captain Kirk, actor William Shatner; Tracy Drain, Juno mission deputy chief engineer; Jeff Berner, DSN chief engineer; and Annabel Kennedy, DSN command engineer.
