Purpose and description
Enable an AI agent to recognise astronautics as a field of knowledge, assess the applicability and maturity of its knowledge, and select appropriate methods for analysing spaceflight.
Astronautics is the science and engineering of flight beyond Earth's atmosphere, encompassing the design, operation, navigation and control of spacecraft and their missions.
It can be Classify a knowledge claim or research problem as central, overlapping or outside astronautics under an explicit scope convention.; Route a spaceflight question to relevant specialisations and identify dependencies between them.; Select analysis methods whose assumptions match the flight regime and available evidence.; Compare competing technical claims using validation context, uncertainty and demonstrated applicability.; Identify missing knowledge or verification evidence before a proposed concept informs mission design.; Map astronautics coverage across curricula, reference works and classification schemes..
Distinguishing features
Its central questions concern enabling, analysing or conducting spaceflight; studying celestial objects alone does not establish astronautics coverage.
Compared with aeronautics, its methods must address flight beyond sustained atmospheric aerodynamic support, while retaining atmospheric launch and return interfaces.
Compared with astrodynamics, it includes vehicle engineering, propulsion, environmental constraints and mission operations as well as motion.
Compared with aerospace engineering, it identifies the spaceflight portion of a broader field; the exact disciplinary boundary requires a named convention.
A spacecraft or mission is an application of astronautics; the field itself consists of organised knowledge, methods and recognised areas of inquiry.
Scope
+ Definitions and conventions that distinguish astronautics from neighbouring disciplines
+ Knowledge of spaceflight dynamics, trajectories, guidance and control
+ Engineering knowledge concerning spacecraft, propulsion and operation in space environments
+ Methods for mission analysis, verification and assessment of technical maturity
+ Disciplinary classifications, educational coverage and institutional recognition
- Individual spacecraft, launch vehicles and their component inventories
- Execution records and operational status of particular space missions
- Astronauts and other practitioners as people or occupational roles
- Astronomy concerned with observing and explaining celestial phenomena independently of spaceflight
- Space agencies, companies, societies and publications as individual entities
- Space law, policy and economics as independent disciplines
Characteristics
- Adopted disciplinary definition
- Source-attributed definition with inclusions, exclusions and date Prevents an agent from treating one institution's scope convention as universal.
- Spaceflight regime coverage
- Launch and ascent; orbital flight; transfer and escape; interplanetary flight; entry, descent and landing; other explicitly defined regimes Identifies where a method or body of knowledge applies.
- Specialisation relationships
- Named subfields and neighbouring disciplines, with source-supported relation types Supports navigation between astronautics and narrower or overlapping knowledge models.
- Method applicability conditions
- Physical assumptions, environmental bounds, reference frames, timescales and neglected effects Determines whether an analysis method is appropriate for a proposed spaceflight problem.
- Knowledge validation state
- Proposed; analytically assessed; simulated; ground tested; flight demonstrated; contested, with evidence and context Distinguishes theoretical feasibility from demonstrated performance without assigning one maturity level to the whole field.
- Classification placement
- Classification scheme, edition, code, label and mapping scope Allows comparison across catalogues without inventing a single authoritative classification.
- Institutional recognition
- Relevant curricula, professional societies, journals and reference works, with the coverage each supports Provides evidence of disciplinary organisation while keeping institutions separate from the field.

What the second pass must settle
- Which authoritative definition should anchor this registry entry, especially at the boundary between astronautics and aerospace engineering?
- Does an existing Vercy world model already cover astronautics, requiring a registry link instead of a separate publication?
- Which classification codes and editions explicitly cover astronautics, and which only cover broader or narrower subjects?
- How should the adopted scope place human spaceflight, planetary surface operations and in-space manufacturing relative to neighbouring models?
