description: "Knowledge base from NASA-STD-8719.14C (Process for Limiting Orbital Debris). Use for orbital-debris assessment planning, mission-related debris limits, explosion/passivation and collision risk, postmission disposal options, reentry casualty risk, and ODAR/EOMP governance. Covers STD-8719.14C (Approved 2021-11-05) synthesized notes only; does not replace NPR 8715.6 delivery timing, NASA-HDBK-8719.14 environment/modeling depth, or program-specific OSMA waivers."

# Process for Limiting Orbital Debris (NASA-STD-8719.14C)
**Source**: NASA-STD-8719.14C (Approved 2021-11-05) (US Government work, public domain) | **Chapters**: 7

## When to use
Reach for this pack when planning or reviewing NASA (or NASA-sponsored) orbital-debris assessments — applicability and NPR 8715.6 framing, assessment overview and tools, debris released in normal operations, explosions/breakups and collisions, postmission disposal of space structures, reentry surviving debris, or ODAR/EOMP content and special-mission classes.

**Prerequisites:** none — plain Markdown; no MCP server, API key, or licence tier needed at runtime.

## How to Use This Skill
- **Without arguments** — load the core frameworks below.
- **With a topic** — ask about ODAR, EOMP, 25-year LEO lifetime, GEO disposal, passivation, DAS/ORSAT, or reentry casualty risk.
- **With a chapter** — ask for `ch01` through `ch07`.

Supporting files: `glossary.md`, `patterns.md`, `cheatsheet.md`.

## Core Frameworks & Mental Models

### NPR + standard pair
- **NPR 8715.6**: When assessments and reports are required and delivered.
- **NASA-STD-8719.14C**: Technical shalls and assessment methods for those reports. Handbook 8719.14 is a reference companion — not ingested here.

### Six assessment issues (ODAR spine)
1. Debris released during normal operations.
2. Explosions and intentional breakups.
3. On-orbit collisions (large objects + small MMOD that can kill disposal).
4. Reliable postmission disposal of spacecraft and orbital stages.
5. Surviving reentry debris / human casualty risk.
6. Special classes (tethers, smallsats, large constellations, servicing, ADR).

### Technical-area template (every §4.x)
Definition → Requirements → Rationale → Methods to assess compliance → NASA mitigation summary.

### Disposal preference
Immediate removal (direct reentry or Earth escape) is the preferred 2019 ODMSP option. LEO default is “as short as practicable, ≤25 years.” Storage and long-term reentry are constrained alternatives, not a free graveyard.

### Evidence pair
- **ODAR**: design-time compliance case (Initial / PDR / CDR / Final).
- **EOMP**: living operations plan so mission use does not preclude safe passivation and disposal.

## Scope & Limits
This pack covers **NASA-STD-8719.14C (Approved 2021-11-05)**, Process for Limiting Orbital Debris, as synthesized reference notes from the official NTSS PDF (77 pages per extraction metadata). It does **not** ingest NASA-HDBK-8719.14, replace NPR 8715.6 delivery tables or OSMA waiver process, reproduce DAS/ORSAT user manuals, or dump every figure/table. IADC, UN, SPD-3, and 2019 ODMSP are cited as consistency references, not licensed inserts. US Government public domain work. No source-material download link is published.
