About Reentry

Reentry is an independent publication about what falls back to Earth, the debris piling up in orbit, and the technology racing to keep space usable.

What we cover

We report on three connected beats. The first is reentry: how satellites, rocket stages, and stations come back through the atmosphere, what survives, and the returns worth remembering. The second is space debris: how much junk is in orbit, why it threatens the satellites we depend on, and how it gets tracked and cleaned up. The third is the frontier technology shaping the same sky, from megaconstellations to quantum computing. Our aim is a publication a curious reader and a working engineer can both trust.

How we source and fact-check

Every figure on this site traces to an original or reputable source, and we link them. Our anchors are the organizations that actually measure orbit: ESA's Space Environment Report, NASA's Orbital Debris Program Office, the US Space Force catalogue on Space-Track, The Aerospace Corporation, and independent trackers such as Jonathan McDowell. Our data pages, the reentry watch and the recovered debris catalogue, cite a source for every row.

We are careful about the line between what is known and what is not. A reentry prediction made days out carries real uncertainty, and we say so rather than implying precision we do not have. When a bright streak in the sky has no confirmed source, we call it a candidate, not a fact. We do not present a dated snapshot as a live feed. That discipline is the whole point of a real publication.

Who is behind Reentry

Reentry is written and edited by a small independent team of science and technology writers. We are not affiliated with NASA, ESA, the US Space Force, or any space agency or company, and we do not speak for them. We link to those organizations often because they hold the source data, not because they endorse us. Reentry is funded through advertising and sponsored and contributed articles, which are labelled clearly and held to the same accuracy standard as our own reporting.

Corrections

We fix mistakes. If you spot an error, from a wrong date to a mislabeled object, email editor@reentrynews.com and we will review it. Substantive corrections are noted on the page they affect. Orbit is a fast-moving subject and the figures change, so we date our pages and update them as the sources do.
