Editorial standards

• No advertiser, sponsor or partner pays for coverage, sees an article or report before it publishes, or has a say in what we cover or conclude.
• Money never changes our data, a Space Score, a tracker, a ranking, a fact-check or the order of search, directory or job results. Paid items are labelled in words (“Advertisement”, “Sponsored”, “Partner content”, “Featured”, “Presented by”, “Enhanced listing (paid)”) before the content. The full rules are in the advertising policy.
• Sponsored articles (partner content) are not journalism. They are fact-checked and labelled. For 14 days they may appear in a few labelled, fixed-position slots (a news-feed card, the end of related articles, a homepage card, one labelled block in Monday's SpaceNexus AM email, added after the brief is written), never mixed into the order of our news, and they are kept out of RSS feeds and search and never shown to the AI that drafts our products.

• Our standard is that every figure carries a source and an as-of date. Where a number on the site is missing either, that is an error: report it and we will fix it.
• We prefer primary sources: regulators' filings, agency data, company disclosures, Launch Library 2 for launches, SEC filings for public companies, and official procurement records. The data sources page lists what we ingest, and the methodology page explains how each computed number (Space Score, rankings, funding totals, jobs counts, satellite passes and the rest) is made.
• Estimates are labelled as estimates, and say what they are based on. We do not publish invented or placeholder numbers; where data is missing we say so instead of filling the gap.
• Launch dates move. We record the move rather than silently replacing the old date (see the Launch Slip Index).

SpaceNexus uses Anthropic's Claude models to draft some content. Anything AI-drafted is labelled as such, and is built from inputs that exclude advertising, sponsor messages and partner content. What is true today:

• AI insights carry the byline “SpaceNexus Desk”, which names a process, not a person. The pipeline:
  1. Selection. A daily job at 01:00 UTC (retried at 07:00 UTC) reads the last 24 hours of the aggregated news pool plus our own structured data (launch records, hiring snapshots, funding rounds, regulatory filings) and picks the stories worth an analysis piece. Titles published in the previous 14 days, including ones that were rejected, are shown to the selector so killed stories stay killed.
  2. Drafting. Claude Sonnet writes the draft against the selected sources. It is given the source articles and our data; it is not given a house line to argue.
  3. Fact-check. A second, separate model pass checks every claim in the draft against the cited sources and returns one of three verdicts: pass, minor issues, or major issues.
  4. Publication gate. Pass and minor-issues drafts publish automatically. Major-issues drafts are held as pending_review and emailed to the founder, who approves or rejects each one by hand. Nothing with a major-issues verdict reaches the site unread by a person.
  5. Sourcing. Every published piece lists the sources it was written from, and each carries a confidence badge derived from how many independent sources it stands on.
• The weekly lunar article is drafted by AI from the SpaceNexus lunar database and the news sources it lists, fact-checked by a second, independent AI pass against those same inputs, and published automatically when the checks pass (automatic publication is currently switched on); the editor can still withdraw it.
• Mission debriefs are drafted by AI from Launch Library 2 event data and news coverage. The outcome (success, failure, partial) is taken from Launch Library 2's confirmed status, never from the model, and a debrief that contradicts it is taken down. Drafts that pass automated quality checks publish without a person reading them first, and each one says so.
• SpaceNexus AM, the weekday morning email: the lead and each story's headline and why-it-matters line are drafted by AI, then checked against the same reporting by a separate AI fact-check before sending. If the check flags a problem, the issue goes out with the publishers' own headlines instead. Links, sources and dates come from the underlying articles; the launches, money, hiring and history sections come straight from our data. An issue that fails its automated checks is withheld.
• Week in Space Data (the Friday email) contains no AI-written text: its numbers are computed, and every linked piece is labelled SpaceNexus Desk (AI-drafted, fact-checked) or SpaceNexus Data (computed).
• Data briefs (State of the Space Economy, Who's Hiring in Space, the Hiring Index and the Launch Slip Index) are computed from our database. No AI writes them.

To report an error, use the corrections form or the “Report a correction” link on an article. This applies to sponsored content too: we fact-check partner articles before they publish and correct them after.

• Tell us what is wrong and, if you can, what the right figure or date is and where it comes from.
• Factual errors are fixed in place and the piece gets a dated correction note at the foot. We do not quietly re-edit a claim out of existence.
• If a piece is wrong in its premise rather than its details, it is withdrawn and the URL says so instead of 404ing.
• Corrections are handled by the founder directly, not by the pipeline that wrote the piece.

SpaceNexus is a one-person company. Jay Griffiths, the founder, is the responsible editor: he receives the held-article queue, approves or rejects every major-issues draft, and answers corrections.

Every material correction we have made is listed, with its date, on the corrections page.

• We do not accept payment, gifts or favours for coverage, and we do not accept payment to promote a security.
• A company that advertises with us, sponsors a report or posts a paid job is covered, scored and ranked exactly as it would be otherwise; claiming a company profile is free and changes nothing either. Its paid relationship is shown by the label on the paid item.
• Where SpaceNexus or its editor has a financial interest in a company a piece is about, the piece says so.
• Outside contributors, investors included, write unpaid and are named with their firm. They disclose any financial interest in a company they mention, the disclosure is printed with the piece, and a contribution may not promote their fund, portfolio or products (partners and contributors).
• Nothing on SpaceNexus is investment advice.
