Ephemera ephemera.space

The largest constellation in history publishes where it is going, with uncertainty, every eight hours — and the files vanish at the next cycle. Ephemera keeps them.

The archive has been running since 30 August 2026. As of 31 August 2026 it holds four complete eight-hour cycles — every file hashed, each cycle bound into a Merkle root, anchored with OpenTimestamps, and sampled into the Wayback Machine.

This page is a placeholder. The archive ledger and a daily scoreboard — how well the public satellite catalogue can actually see the constellation — are under construction.
