Duranki – The Bond of Heaven and Earth

IPIS / Duranki – InterPlanetary Identity System

“There’s a starman waiting in the sky…” – David Bowie, Starman (1972)

IPIS (InterPlanetary Identity System) is a voluntary protocol for identification, access control, and navigation in the Solar System. Its codename is Duranki (ancient Sumerian for The Bond of Heaven and Earth).

IPIS gives every object (human, spacecraft, robot) a human‑readable code and a stackable history of visited worlds – the Snezhkov Stack.

It does not replace national flags or existing systems (NORAD, transponders). It works alongside them, creating a shared semantic layer for space activities.

Key Features

• Simple coding – circle (human/base), hexagon (robot), numbers 01 (Earth), 02 (Moon), 03 (Mars), indices ' (orbit), E (EVA), 00 (deep space).
• Snezhkov Stack – horizontal row of touching small discs, each with a world number. First disc = birthplace, then work locations (>6 months). E disc after any world where EVAs were performed.
• Ship Thread – straight line on the hull from start to end node (e.g. 01—03). Intermediate manoeuvres are digital only.
• Two‑layer patch – outer layer shows current code; under it hides a flat disc (future stack element). When you leave a base, the outer layer is peeled off and the disc is added to your stack. No need to print new patches in space.
• Ritual “Base Gulp” – a glass of local water, a sip, the sound of Velcro – a symbolic admission into the new ecosystem.
• Technical integration – RFID chips in patches for access control; IPIS_CODE field in NORAD / Space‑Track.org catalog. Stack verification is based on ship and base logbooks (digitally signed).

Quick Example

A person born on Earth (01), who worked on a lunar orbital station with EVAs (02’E), and is currently on Mars (03):

• Main patch: circle with 03
• Stack: 01 02’ E
• Two‑layer mechanism: when leaving the lunar station, the outer 02’ patch was peeled off and the inner disc 02’ (plus the E disc earned there) became part of the stack.

How to Use This

1. Quick start – Quick Start for Beginners – make your first IPIS patch in 5 minutes.
2. Read the presentation – Slides (convert to PDF for printing).
3. Learn the stack mechanics – Stack Guide for detailed patch donning / updating.
4. Dive into technical integration – RFID spec and NORAD extension.
5. Explore cultural examples – Stack Examples (Major Tom, John Carter, etc.).

The system is open – you can adopt, modify, and pilot it. Feedback and contributions are welcome.

Contributing

We welcome contributions of all kinds: bug reports, design improvements, code, translations, and community building.
Please read CONTRIBUTING.md and our Code of Conduct before submitting anything.

Ways to help:

• Create a mod for Kerbal Space Program, Star Citizen, or Elite Dangerous.
• Translate documentation into other languages.
• Improve SVG assets or add new examples.
• Write a script to convert NORAD IDs to IPIS_CODE.
• Spread the word – articles, videos, social media.
