In 1976, Carl Sagan placed a map of Earth's deep time inside a NASA satellite — not as a message to alien civilizations, but as a quiet testament to the planet's own impermanence. The plaque depicts three faces of Earth across nearly 277 million years of geological transformation, from ancient Pangaea to a future no human will witness. It is a rare act of humility embedded in metal: an acknowledgment that the ground beneath us is always moving, and that some truths are worth preserving for times beyond our own.
