NASA invites people to send text to farthest man-made object
NASA is inviting people to send a short message to one of the interstellar Voyager mission spacecraft currently over 20 billion km from Earth, the farthest a human-made object has ever reached. One of the messages from social media tagged #MessageToVoyager will be selected to beam into deep-space on September 5, 2017, marking the 40th anniversary of Voyager 1's launch.
