Purpose and description

Enable an AI agent to recognise a Soyuz crewed spacecraft, assess its configuration and mission state, and identify actions supported by configuration-specific evidence and authority.

Soyuz is a Soviet-origin family of crewed orbital spacecraft with an orbital module, a reentry capsule and a service module, designed to transport people to and from low Earth orbit.

It can be Classify a Soyuz reference as spacecraft family, variant, individual vehicle or launch-vehicle namesake.; Compare a documented configuration with crew transport and return requirements.; Check proposed rendezvous and docking compatibility against target-interface evidence.; Assess whether endurance and attached-duration limits support a proposed mission interval.; Identify missing evidence or restrictions affecting departure, return or recovery readiness.; Route a proposed action to the applicable approved procedure and responsible authority..

Distinguishing features

Determine whether the referent is the crewed spacecraft or the launch vehicle: the shared Soyuz name alone does not establish identity.

Check for the characteristic orbital module, descent module and instrumentation/propulsion module arrangement against documentation for the stated variant.

Establish that the descent module supports crewed atmospheric return; a related cargo vehicle with similar external features is not sufficient.

Require an explicit Soyuz variant or documented family relationship rather than classifying every Russian crewed capsule as Soyuz.

Distinguish a reusable family description from a named mission, serial-numbered spacecraft or museum article.

Characteristics

Documented family and variant
Documented Soyuz variant designation; unresolved Architecture, interfaces and operating limits must be attributed to the applicable variant.
Configuration evidence
Applicable technical document, revision and configuration identifier Prevents capabilities from different Soyuz generations being combined into an unsupported configuration.
Module attachment state
For each module: attached, separated, unknown; interpreted by mission phase The vehicle's available functions and return readiness change when modules separate.
Crew and seat configuration
Occupant-to-seat, restraint and pressure-suit compatibility records A nominal seat count does not establish that a particular crew can safely return.
Available crew places
persons, conditional on variant and installed equipment Supports transport and evacuation assessments without assuming all configurations have identical capacity.
Autonomous endurance
hours or days, with crew load and operating assumptions Separates free-flight support capability from permissible time attached to a station.
Permitted attached duration
days, with configuration-specific limits and extension authority A spacecraft attached to a station still has time-limited return capabilities.
Rendezvous and docking compatibility
Spacecraft equipment configuration matched to target port and supporting systems Mechanical compatibility alone does not demonstrate an achievable rendezvous and docking.
Mission phase
Prelaunch, ascent, free flight, rendezvous, docked, departure, deorbit, descent, landed, unknown Determines which capabilities, hazards and readiness criteria apply.
Return-system readiness
Verified ready, restricted, unavailable, unknown; supported by subsystem evidence An intact or docked Soyuz cannot automatically be treated as an available return vehicle.

Drafted structure

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.

Soyuz identity and applicability Resolve the Soyuz referent and establish which spacecraft configuration a claim describes.

Soyuz names both spacecraft and launch vehicles, while spacecraft variants cannot safely share every capability claim.

Registry referent

Establish the intended kind and its boundary.

Spacecraft family boundary

The draft assumes the crewed spacecraft family; registry provenance must support that interpretation.

  1. Which originating registry or Wikidata record establishes whether Soyuz denotes the spacecraft family or the launch-vehicle family? provenance
  2. Does an existing Vercy model already own this concept and require linking rather than another publication? boundary

Variant applicability

Attach capability claims to documented Soyuz variants and configurations.

Configuration-specific claims

Record the variant and document applicability before treating a feature or limit as usable evidence.

  1. Which documented Soyuz variant and equipment configuration does this description cover? definition
  2. Which source revision supports extending each capability claim to that configuration? provenance
Modules and flight functions Describe Soyuz's module arrangement and the functions available in each flight configuration.

Soyuz operates as a joined spacecraft before returning its descent module, so module boundaries determine capability and loss of capability.

Module function allocation

Identify functions and interfaces associated with the three principal modules.

Three-module architecture

Use the orbital, descent and instrumentation/propulsion modules as the starting architectural distinction, verified for the applicable variant.

  1. Which habitation, docking, control, power and propulsion functions are assigned to each module in this variant? definition
  2. Which intermodule connections must remain available for the current mission phase? boundary

Orbital resource state

Relate usable electrical and propulsion resources to Soyuz flight tasks.

Maneuver and power margin

Represent resource sufficiency against named rendezvous, departure and return obligations rather than a generic operational label.

  1. What usable propulsion and electrical reserves are established, in which units and under which operating assumptions? measurement
  2. Which planned maneuvers or contingency obligations become unsupported when those reserves fall below documented limits? action
Crew support and endurance Represent crew accommodation and time-dependent support constraints during free flight and station attachment.

Soyuz's transport and return roles depend on actual crew compatibility and consumable margins, not simply nominal occupancy.

Crew return fit

Connect occupants to the equipment required for their flight and return.

Occupant equipment compatibility

Treat seats, restraints, suits and applicable occupant limits as evidence needed to assign crew places.

  1. What seat, restraint, pressure-suit and occupant-fit requirements apply to this Soyuz configuration? definition
  2. What verified equipment allocation supports each proposed occupant's return? provenance

Support duration

Separate autonomous life-support endurance from allowable attached service duration.

Duration limits and consumables

State duration limits with crew loading, resource assumptions and documented extension conditions.

  1. What autonomous endurance is supported by the available atmosphere-control resources, water, power and other limiting provisions? measurement
  2. What attached-duration limit applies, and what evidence and authority support any extension? provenance
Rendezvous, docking and station role Capture target compatibility, relative-flight capabilities and Soyuz's role while attached.

A Soyuz serving a station must both reach a compatible port and retain the capability required for its assigned departure or return role.

Target and control compatibility

Match Soyuz rendezvous and docking equipment to a specific target interface.

Compatible approach and capture

Assess docking hardware, relative-navigation support and available control modes together.

  1. Which target ports and supporting rendezvous systems are compatible with this Soyuz configuration? boundary
  2. Which automatic and crew-controlled approach capabilities are documented, and what conditions restrict their use? action

Attached return availability

Assess Soyuz as an attached vehicle with a continuing departure and return obligation.

Station return role

Represent assigned occupants, station dependencies and readiness evidence for the attached spacecraft's return role.

  1. Which crew members and return obligations are assigned to this Soyuz while it is attached? boundary
  2. What documented checks establish that station-supported operation can transition to autonomous departure and return? action
Return, descent and recovery Represent the irreversible transition from orbital spacecraft to descending capsule and recovered vehicle.

Soyuz return depends on coordinated deorbit, module separation, descent protection and landing systems whose readiness must be assessed by phase.

Deorbit and module separation

Connect orbital departure conditions to the configuration required for atmospheric entry.

Entry configuration readiness

Track evidence for deorbit capability and required module separation without turning the model into an execution procedure.

  1. Which configuration-specific conditions establish deorbit and module-separation readiness? action
  2. What evidence distinguishes confirmed separation from an indication whose reliability remains unresolved? provenance

Descent and ground recovery

Relate descent-system condition, landing expectations and recovery support.

Landing and recovery constraints

Record variant-specific descent modes, thermal protection, parachute and landing-system requirements alongside recovery dependencies.

  1. Which descent modes and thermal-protection, parachute and landing-system limits are documented for this variant? definition
  2. Which landing-area, environmental and crew-condition constraints determine required recovery support? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.

A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
