NASA wants you (yes, you。) to help celebrate the 40th anniversary of the Voyager mission.。

In honor of four decades of Voyager 1 — humankind's farthest-flung spacecraft — NASA is inviting people everywhere to share an uplifting message for the spacecraft using the hashtag #MessageToVoyager.。

NASA will even beam one lucky person's #MessageToVoyager into space, according to a press release. The messages can be sent through social media, including Twitter and Facebook. 。

The effort is inspired by "messages of goodwill" from Voyager's Golden Record, a disk which contains sounds and images of life on Earth which was carried aboard Voyager 1 and Voyager 2 in 1977 on their tours of the solar system's planets. 。

Thanks for signing up!。

In order to submit messages for consideration, people must use the hashtag #MessageToVoyager by 11:59 PM PDT on August 15. 。

It would be a pretty kind gesture for a spacecraft that's all alone up there. 。

Submissions will be judged by NASA, the Voyager team, and the Jet Propulsion Laboratory, before the public has the ability to select a final, winning message through an online poll. 。

That winning message will be beamed into space on Sept. 5 — the anniversary of of Voyager 1's launch in 1977. But that's just the day the message will be launched. It won't reach the vicinity of Voyager 1 until the next day.。
