Method, evidence and resilience for space-based services.
Space and Earth Observation is designed to publish Earth observation method guides, land and ocean observation cases and space-system risk briefs. Its methods combine satellite data science, Earth observation models and attention to uncertainty and rights. It is distinct from the Earth observation platform (EOP) in Foundry, which renders shared Earth observation data across the Consortium; this platform is the research community behind the methods.
Sensors and products
How each sensor type sees the Earth, what it can and cannot measure, and how products are validated against ground observation.
Evidence for decisions
Water, agriculture, ecosystems and disasters: how satellite evidence is used, where it adds most and where it is weakest.
Space system resilience
The vulnerabilities of satellites, ground segments, navigation and communications, and the stewardship of orbital space.

Stocks, flows, delays and a tipping threshold.
Two stocks, pressure and adaptive capacity, joined by a reinforcing growth loop, a delayed balancing response and damage when pressure outruns capacity; past the threshold the system can tip. Teaching model with stated illustrative values, not a prediction. The map on this page shows The Arctic; the model itself is not tied to a place.

What Space and Earth Observation does.
Earth observation is the gathering of information about the planet’s surface, water and atmosphere from satellites and aircraft. Space and Earth Observation covers sensors, analysis-ready evidence, space system resilience, communications and navigation, water and agriculture, disaster monitoring, debris and geospatial governance. Space agencies, operators and mapping authorities decide.
Its community
Remote-sensing scientists; space engineers; geospatial analysts; disaster scientists.
Its methods
Satellite data science; EO models; uncertainty and rights.
Its outputs
EO method guides; land/ocean observation cases; space-system risk briefs.
Model Space and Earth Observation as a system. Run the cascade.
Assembled from the Nexus Standards area profile Climate risk standards: the hazards it names, the systems and sectors that carry the loss, the controls that dampen it and the data that observe it. Choose the components, pick an initiating hazard and step through the cascade. The Map view places the run on an example geography with open data. Every coupling weight is a stated assumption you can change. A teaching model, not a forecast, an assessment or a certification. To model a place of your own choosing, open the full System Builder.

What Space and Earth Observation studies, and who governs space.
Space and Earth Observation, studies the satellites and ground systems that observe the planet and position and connect people, and the risks to those systems in orbit. Space agencies, operators, spectrum regulators and mapping authorities decide; GCRI operates no satellite and orders no acquisition as an authority.
Imagery and orbit illustrations here are examples; imagery products keep their providers’ licences.
How Space and Earth Observation is modelled, measured and tested.
The model, its assumptions, its data and its uncertainty, in the form a scientist or engineer would check. Structures follow published methods. The values drawn are illustrative, not findings.

Where space evidence goes.
Earth-observation evidence is designed for the Observatory Signal series; space system resilience for the Strategic Systems series. Products would carry NS-3b metadata under the proposed Nexus Standards.
- Agencies can share validation data.
- Field teams can contribute reference observations.
- Researchers can contribute debris and space weather studies.
A dependency in orbit, and evidence from above.
Satellites observe the whole planet repeatedly. Optical, radar, thermal and other sensors record floods through cloud, crop condition across continents, sea-surface temperature, forest loss, urban growth and the ground deformation that can precede landslides. For many places, satellite data is the only consistent record of environmental change, and it has become central to weather forecasting, climate monitoring, disaster response and resource management.
That evidence is powerful and easily misread. A satellite measures radiation reflected or emitted from the surface, not the quantity a decision-maker cares about. Turning measurements into maps of flooded area, crop yield or damage requires models, calibration and ground truth, each with errors that vary by place, season and sensor. Products with very different accuracy can look equally authoritative on a screen. Without stated uncertainty and validation, satellite evidence can mislead the decisions it is meant to inform.
Society also depends on space in a second way. Satellite navigation provides the timing signals used by telecommunications networks, power grids and financial systems, as well as positioning for transport and agriculture. Satellite communications connect remote areas, ships, aircraft and disaster zones. These services can fail through space weather, interference, cyber attack, ground-segment faults or collisions in increasingly crowded orbits, and a failure can cascade into systems on the ground that have no obvious link to space.
Steward of four STEM methods, connected across three institutions.
The platform stewards Earth observation and remote sensing, space systems and satellite services, geospatial information systems and spatial statistics and geostatistics in the STEM Commons, which other platforms apply. It also draws on high-performance, cloud and edge computing, communications and network technology and physics. See the STEM foundation.

The areas of space and Earth observation this platform takes on.
Space and Earth Observation studies the satellites, ground systems and data that observe the planet and connect and position people on it, and the risks to those systems in orbit. Its pages set out how Earth observation sensors work, how space-based evidence is made reliable, how it serves water, agriculture and disaster monitoring, and how space systems, debris and geospatial data are governed, with every value labelled by its evidence and every limit stated. It prepares evidence; space agencies, operators and mapping authorities decide.

Every claim on Space and Earth Observation rests on methods with a canonical page in the STEM Commons, so readers can see what a finding depends on and where its limits lie.
How work moves in this field.
A question becomes evidence, a governed build, an organised community, a controlled test, a reviewed publication and, finally, a decision taken by the competent authority under its own rules.

How this works across the six pillars.
Space and Earth Observation works through six pillars of one annual programme, led by the Nexus Consortium, with GCRI, the Global Risks Forum (GRF) and the Global Risks Alliance (GRA) each contributing in its role: explore, experiment and prototype in Labs, build, simulate and prepare in Foundry, convene and test in Universe, codify, correct and apply in Nexus Standards, publish in every format in Reports, teach in the open in Risk Academy.

How Space and Earth Observation works
Platforms · Programme year · Standards · Reports
A platform joins a field to named methods, labelled evidence and the outputs it publishes, without becoming the authority it serves.
01 Scope
- 01Field and familiesStart · The platform leadThe home states the field, its families and who it serves.
- 02Topic dossiersRecord · Platform authorsTopics explain the subject with labelled evidence.
02 Evidence
- 03Evidence labelsRecord · GCRIEach value is labelled: observed, published statistics, estimated, modelled, scenario or unknown.
- 04MethodsStep · Method ownersMethods come from the STEM Commons, each with one canonical page.
03 Work
- 05Scenarios on the systemsModel · Foundry pillarScenarios run on the Nexus systems, labelled as scenario.
- 06Standards that applyRecord · Nexus StandardsThe platform names the standards that apply. A validator report is evidence for review.
04 Publish
