HI JUNO
Earthlings send a globally coordinated signal to a spaceship
In a simultaneous global effort, thousands of people around the world sent a synchronized greeting from Earth that was heard by the Juno spacecraft. Thank you for all who participated and said “HI” to NASA's spacecraft as it passed by Earth on its epic journey to Jupiter!
The first video is a short overall documentary of the project, the second shows the actual data.
