Golden Message Adrift: Pioneer 10, Pulsar Map and a Quiet Cosmic Drift

Pioneer 10 carries a gold plaque showing a man and a woman alongside a pulsar-based map meant to mark Earth’s location for any finder; the spacecraft has been silent since 2003 and is now drifting outward toward Aldebaran, a journey NASA estimates at about two million years, though the star’s own motion means it isn’t a fixed rendezvous. The plaque was designed as a durable, albeit uncertain, message to distant intelligences, and while the craft may fade, the plaque’s intended message endures as a symbol of human curiosity.
