Artemis Accords Explorer

Click any country on the map to select it. Signed nations appear in teal; non-signatories in light gray. Use the dropdown or quick-select chips to jump to a specific country. Toggle labels, accession years, or color-by-wave to customize the view. The signatory list and timeline tabs offer alternative views of the same data.

Browse all 10 Artemis Accords principles with plain-language summaries. Each principle shows its compliance status for the currently selected mission (in Mission Planner mode). Filter by status to focus on areas needing attention. Principles are grouped by theme: Peaceful Purposes, Transparency, Interoperability, Emergency Assistance, Registration, Scientific Data, Heritage Protection, Space Resources, Deconfliction, and Debris.

Design a hypothetical lunar mission: name it, choose a target region and mission type, select a lead signatory nation, and add partners. The checklist lets you mark which principles your mission addresses. Click Check Compliance to see a detailed assessment with a compliance score, principle-by-principle breakdown, and an exportable dossier.

Every compliance check generates a downloadable JSON dossier with the mission configuration, compliance scores, principle assessments, and a timestamp. Your last mission and map selections persist in localStorage and restore on reload. Use Reset in the mission planner to start fresh.

Signatory data reflects the 74 nations confirmed by NASA as of September 2026, including Croatia (74th). Accession dates are sourced from NASA press releases. The 10 principles are summarized from the official Artemis Accords text. This tool is for educational and planning purposes only — it does not constitute legal advice or official compliance certification. Compliance logic is a simplified heuristic; real missions require formal review by relevant authorities.
