The Global Centre for Risk and Innovation (GCRI)
Space and Earth observation brings together the science of observing the Earth from orbit and the engineering of the space systems that make it possible. As a risk field it has two faces: satellites as a source of evidence about hazards, ecosystems and human activity, and satellites as critical infrastructure whose failure would ripple through systems on the ground. This overview sets out why the field matters and what experts study.

The Space and Earth Observation field covers space systems and the Earth-observation technologies used for risk intelligence and sustainable development. Experts in it study questions such as Earth observation sensors and spatial temporal evidence, with methods such as Earth observation and remote sensing as well as space systems and satellite services. Its counterparts at GRF and GRA look at the same systems through governance and finance.

The working screen behind this subject: its structure, terms and states. Names are placeholders and values illustrative.
Earth observation offers what ground networks cannot: consistent, repeated coverage of the whole planet, including oceans, remote land and places where access is unsafe. It underpins weather prediction, tracks the climate system, and supports decisions on water, food, forests, cities and disasters. For countries with sparse monitoring networks, it can be the main source of environmental evidence.
The value of that evidence depends on continuity and quality. Long, consistently calibrated records allow change to be separated from noise, and products validated against ground observation can be trusted for decisions. Gaps between missions, undocumented processing and unvalidated products weaken the evidence base for every field that uses it.
At the same time, many essential services rely on space without their users noticing. Navigation satellites provide precise timing that synchronises telecommunications, electricity networks and financial transactions. Satellite communications provide backup when ground networks fail. These dependencies make space a part of critical infrastructure, with risks that need to be understood alongside its benefits.

Each term as this page uses it. Where a standard-setting body defines the term, the wording follows that body.
| Term | Definition |
|---|---|
| Space debris | Non-functional human-made objects in orbit, including dead satellites, rocket bodies and fragments. |
| GNSS | Global navigation satellite systems, such as GPS and Galileo, that provide positioning and timing. |
| Spatial data infrastructure | The policies, standards, technology and people that let geospatial data be shared and used. |
| Systemic risk | Risk arising from the interactions and dependencies within and between systems, where a shock can propagate and threaten the functioning of the whole. |
Satellite evidence feeds almost every environmental and hazard field, while space infrastructure supports energy, telecommunications, transport and finance. Dependencies and consequences maps those links.
The current service level is R0: information and enquiries. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
