about
Vesperio tracks the commercial space economy and the events that move it. Coverage of Chinese, Indian, Japanese, and European activity gets equal weight to US activity.

What is Vesperio?
A machine-maintained tracker for the new space economy: Earth observation, connectivity, launch, and commercial human spaceflight. It surfaces fresh items twice daily, keeps reference profiles of constellations and launch vehicles, and publishes basic computed statistics.
Who writes the items?
An automated agent drafts every item; deterministic validation scripts check each draft against the schema and editorial hard rules before anything is published. A human reviews the pipeline and its rules, not each item.
What counts as a source?
Every item accumulates sources over its life and links each one. The best source sets the base of its signal-to-noise score: the actor itself or an official record scores highest, wide reporting and established aggregators next, trade press next, informal posts lowest. Corroboration raises a score; contradiction lowers it. The copy still names who said what: ICEYE says, per the FCC filing, per SpaceNews.
What does the SNR score mean?
Every item carries a signal-to-noise score from 1 to 5, drawn as bars. 5 is a direct source: the actor itself or an official record. 4 is wide reporting that nothing has contradicted. 3 is a few reputable sources. 2 and 1 are weak corroboration: single sources, early signals, extraordinary claims. Clicking the bars shows the exact calculation, stored when the item was scored: the base source tier and every adjustment since. Scores move when corroboration, contradiction, or uncontested time changes the picture, and every move is logged.
What happens when a story cannot be verified?
It publishes with a low score instead of disappearing. The wide net is deliberate: readers see early signals with the uncertainty made explicit, and the score climbs only when corroboration arrives or the claim survives uncontested. A claim contradicted by a stronger fact is marked disputed and stays visible with both sides shown. Whether the scores are honest is measurable: each claim's score at publication is recorded and compared against how it resolves.
Are numbers ever estimated?
No. Figures are copied exactly from the linked source or omitted. Registry fields without a current source stay null, and every filled registry field carries its source URL and an as-of date.
Can I cite Vesperio?
Yes. Every stat block on the stats page has a stable anchor and a pre-formatted citation string with a retrieval date, and the same numbers are served machine-readable at /stats.json.
