This learning environment is an educational summary of open sources on the military space domain. This chapter accounts for the sources used: by topic (§ 12.2), as a register (§ 12.3), the doctrinal framework (§ 12.4) and the images (§ 12.5).
| Item | Explanation |
|---|---|
| Purpose | To account for the open sources used for the chapters, the timeline and the reference cards of this learning environment. |
| Method | The material was built from open sources: publications by NATO, the UN and US and European government agencies, open-source assessments by think tanks (Secure World Foundation, CSIS), trade press and Wikipedia, updated to October 2026. Orbital figures are rounded; where sources differ, a range is given. |
| Reference framework | The NATO and US doctrine documents (AJP-3.3, AJP-3.29, JP 3-14) are listed separately in § 12.4. They are not (fully) public; the material follows their public outlines and does not cite them. |
| Reliability | Much of what is known about military space activity consists of claims by states. The performance of lasers and EW, the intent of approaching satellites and nuclear plans cannot be checked independently and appear in the text as claims or as uncertain. Orbits, launches and debris can be measured. |
| Tools | N2YO, Orbital Radar and Space-Track (S17–S19) are included as reference and practice tools (§ 10.6). They only show what is in public catalogues. |
| Images | Photos from Wikimedia Commons under a free licence. See § 12.5. |
