See beyond the sky

Built because the real numbers were always somewhere else

Space is the most documented frontier in human history, and almost none of that record reaches the people who are curious about it. The orbit of a satellite lives in one agency feed, the solar wind speed in another, the next launch window in a third, and the asteroid passing Earth tomorrow in a database most people will never open. STELLUN was built to close that gap.

Every figure here comes from a named source or a documented formula: NASA, NOAA, CelesTrak, JPL Horizons, The Space Devs. Nothing is invented, nothing is smoothed over, and when a source cannot be reached the page says so and shows the last verified reading with its timestamp. That honesty is the whole product.

The purpose is simple. A student should be able to watch the station pass overhead, a researcher should be able to pull a clean orbital element set, and anyone at all should be able to look up and know exactly what is above them tonight. One platform, real data, no guesswork.
