Space Atlas publishes two kinds of content: calculators (an input form and a computed result) and written guides (explanations of a formula, a rate, or a standard). This page states who is responsible for that content, how it is produced, and how to get something corrected. It applies to every page on www.spaceatlas.cloud.
1. Who is responsible
The site is edited by Marcus Reed, who is the named author on published guides. The editor is accountable for what is published, for corrections, and for the sourcing standard described below. Editorial correspondence goes to [email protected] and is read by the editor.
2. How calculators are built
- Formula first. Every calculator implements a published formula or an institutional rule — for example a rate schedule from a carrier or tax authority, a standard test method, a textbook finance identity, or a manufacturer specification. Where a formula has several variants, the guide for that calculator states which variant is used and why.
- Inputs are named and unit-tagged. Fields carry the unit expected (kg or lb, cm or in, percent or decimal). Unit ambiguity is the most common source of wrong results, so it is labelled rather than implied.
- Results are computed, not looked up. A result follows only from the values entered. We do not present a result as a quote, an approval, a filing, or an appraisal.
- Rounding is disclosed. Where a result is rounded, or where a carrier or authority rounds in a direction that changes the amount billed, the guide says so.
3. How guides are written
- Primary sources. Each figure is traced to the body that actually sets it: a statute or regulation, an agency or carrier instruction, a rate schedule, a published standard, or a manufacturer datasheet. We link to that source so the figure can be checked.
- Worked examples, not case histories. Examples are worked illustrations of the arithmetic. Space Atlas does not publish client engagements, consultancy case histories, or claims of professional credentials as evidence for a figure. If an example uses dates and amounts, it is an illustration and is labelled as such.
- Local variation is flagged. Where a value changes by year, country, state, carrier, platform or product tier, the guide names the variable, shows the range, and points to the current source instead of freezing one number.
- No borrowed authority. We do not describe ourselves as practising a licensed profession. Space Atlas is not a law firm, tax or accounting practice, licensed adviser or broker, insurer, lender, carrier, or health care provider.
4. Use of automation
Space Atlas produces content at scale and uses software, including language models, to draft, translate and format it. Automation is a production tool, not a source. Because of that:
- every published guide is reviewed against its primary source before it goes live, and the sourcing standard in section 3 is applied at review, not assumed;
- figures that cannot be traced to a named source are removed rather than published;
- translations are held to the same standard as the English original, and a translation that cannot meet it is withheld from publication;
- pages are dated, so you can see when the content was last checked.
We would rather delete a claim than keep one we cannot source. If you find something on this site that reads like a personal anecdote, a client story or a professional credential, that is a defect: report it and it will be removed.
5. Corrections and updates
- Reporting. Email [email protected] with the page URL, the figure you believe is wrong, and the source you are comparing it to. A link to the source is the fastest route to a fix.
- What happens next. A figure that no longer matches its source is corrected or the page is re-dated to show the point at which it was last verified.
- Dates. Guides and policy pages carry a “last updated” date. A page with an old date is not automatically wrong, but it has not been re-checked since that date.
- No silent edits to substance. Where a correction changes the result of a calculation, the change is described in the update note on the page.
6. Advertising and independence
Space Atlas is free to use and is funded by advertising. Advertising is served by third-party networks and is labelled as advertising. Advertisers have no influence over which calculators exist, which formulas are used, what a guide concludes, or whether a correction is made. Paid placement is never presented as an editorial result, and no advertiser is given advance sight of a guide.
Which cookies advertising partners may set, and how to opt out, is set out in our Cookie Policy.
7. Scope and limits
Everything on this site is general information and a computed estimate. It is not professional advice, and it is not a substitute for the rules of the body that governs your case. See our Disclaimer, Privacy Policy and Terms of Service.
