ECSS Space Standards: Signpost (pointers only)

This is a signpost, not a knowledge pack. It carries no standards-body content: no reproduced clauses, no normative text, no synthesised summaries of the standards. ECSS documents are free to download after registration on ecss.nl, and ESA holds the copyright with no redistribution grant (ECSS-P-00C clause 5.8), so they are Excluded under this repo's docs/SOURCE-VETTING.md and cannot be reconstituted into a redistributable pack. What this skill does: tell you which document you want, which edition is current, who owns it, and which existing NASA pack covers the process topic. A NASA pack is not the ECSS clause set.

When to use

You are working on a European space programme and need to identify or cite the governing ECSS document: which standard covers system engineering, which covers software, which covers dependability, and which free NASA pack covers the process topic. ECSS rows route you to the catalogue. NASA rows route you to an in-repo pack. Several needs have no in-repo pack, and those rows send you to the catalogue only.

Prerequisites: none, plain Markdown.

How to use

Find your document below. The Status column says whether it can be packaged:

• Excluded: free personal download after registration on ecss.nl; ESA copyright; no redistribution grant. Cannot be packaged here. Buy or download from the owner after registering.
• Open: an in-repo NASA pack covers the process topic. The Designation cell names the slug, and the Status cell reads Open. The pack is US Government work, public domain in the US (17 U.S.C. § 105). It is not the ECSS clause set.

Editions were confirmed on ecss.nl product pages on 2026-10-14. E-ST-10-12C is radiation methods, not RAM. E-ST-40C Rev.1 is software. E-ST-70C is ground systems and operations. Do not quote a date this file does not print. Where a public URL slug disagrees with the page title, the Title cell says so and the URL is copied as fetched. A reader who needs a designation not listed here goes to https://ecss.nl/standards/active-standards/ .

Discipline engineering, not the RAM standard and not the software standard

These five are the designations a reader commonly mis-cites. E-ST-10-12 in the table above is radiation methods, not RAM. E-ST-70C in this table is ground systems and operations, not the software standard. The software standard is E-ST-40C Rev.1, last row.

Project management (M branch)

The active management branch is exactly these five documents. M-ST-80C cancels the earlier M-00-03 lineage; that lineage is not a current designation and has no row here.

Sustainability, system description, and two optional rows

Four required rows, then two optional rows. Both optional rows ship, because a reader who asks for human factors or integrated product support will otherwise get silence.

Designation	Title	Edition	Owner	Status	URL
ECSS-U-AS-10C Rev.2	Adoption notice of ISO 24113, space debris mitigation requirements. Listed on the sustainability filter. No verified product-page URL, so the URL is the filter.

Scope & Limits

• No reproduced standards text. Rows carry designation, title, edition, owner, status, and URL only.
• ECSS rows are Excluded. Free after registration is not a redistribution grant.
• NASA rows are Open and name real in-repo slugs. They are process-topic analogues. They do not replace ECSS clause text, European customer-supplier DRDs, or contractual tailoring.
• E-ST-10-12C is radiation methods, not RAM. Dependability is Q-ST-30C Rev.1.
• E-ST-70C is ground systems and operations, not software. Software is E-ST-40C Rev.1.
• No in-repo pack covers structures, mechanisms, communications, ground systems and operations, space environment, radiation methods, planetary protection, product assurance management, or quality assurance.
• No dedicated cost-estimating pack exists in this catalogue beyond nasa-ceh. Schedule is nasa-schedule.
• The communications URL slug says rev-1. The page title is Rev.2. The IPS URL slug is mis-prefixed ecss-e-. Both URLs are copied as fetched.
• se-standards-signpost keeps a shorter ECSS list with no editions. This pack is the edition-pinned map. Do not treat the two lists as the same document.
