We cannot manage what we cannot see. Mapping orbital debris is
the first step toward explaining, regulating, insuring, and sustaining the
orbital commons. |
My Aerospace student Lauren Forcey, under my
supervision, performed an Esri StoryMap GIS project on one of the most urgent
but least visible challenges of the modern space age: orbital debris. Her
project, “Invisible Orbits, Visible Consequences,” explores how thousands of
satellites, retired spacecraft, rocket bodies, and fragments of human-made
material are transforming Earth’s orbital environment into a crowded and
increasingly fragile infrastructure zone.
What began as a GIS class project quickly
revealed a much larger research and communication opportunity: how can we make
the invisible risks of orbital debris visible to scientists, policymakers,
investors, students, and the public?
This blog article presents that idea through
the lens of geospatial science, aerospace sustainability, public communication,
and innovation.
Space
Is Not Empty Anymore
From the ground, space appears silent and
empty. We look up and see a dark sky, stars, and perhaps the occasional
satellite crossing overhead. But near-Earth orbit is no longer an empty
frontier. It has become a working environment filled with satellites,
spacecraft, rocket bodies, and debris fragments moving around the planet at
extremely high speeds.
Satellites now support almost every part of
modern life. They help us forecast weather, navigate with GPS, monitor
wildfires, observe climate change, support agriculture, connect remote
communities, guide aircraft and ships, secure national defense, and synchronize
financial transactions. This orbital infrastructure is essential, but it is
also vulnerable.
The European Space Agency reported in its
2025 Space Environment Report that about 40,000 objects are currently tracked
by space surveillance networks, including about 11,000 active payloads. ESA
also estimates that the real number of debris objects larger than 1 centimeter
is more than 1.2 million, large enough to cause serious damage in orbit.
NASA’s Orbital Debris Program Office gives a
similar warning: more than 25,000 objects larger than 10 centimeters are known
to exist, around 500,000 particles between 1 and 10 centimeters are estimated,
and the number of particles larger than 1 millimeter exceeds 100 million.
Why
Small Pieces Can Cause Big Damage
On Earth, a small metal fragment might seem
harmless. In orbit, the same fragment can become dangerous because objects
travel at very high relative velocities. Even a tiny piece of debris can damage
solar panels, sensors, spacecraft windows, thermal systems, or other critical
satellite components.
A larger object can be catastrophic. A
collision between two satellites, or between a satellite and an abandoned
rocket body, can create thousands of new fragments. Those fragments can then
threaten other spacecraft, creating a chain reaction of debris generation.
This is the concern often associated with the
Kessler Syndrome, a scenario in which collisions create more debris, which then
creates more collisions. The danger is not that all of space becomes unusable
overnight. The more realistic concern is that some valuable orbital regions
could become increasingly risky, expensive, and difficult to operate in.
This is why orbital debris is not simply
“space junk.” It is an environmental, technological, economic, and governance
problem.
The
GIS Question: How Do We Map an Invisible Risk?
Lauren Forcey’s StoryMap matters because it
approaches orbital debris as a geographic problem.
GIS is usually associated with maps of
cities, rivers, roads, forests, land use, or climate risk. But geography is not
limited to Earth’s surface. Near-Earth orbit also has spatial patterns. Objects
are distributed by altitude, inclination, orbit type, density, speed, and
proximity to operational satellites.
In other words, orbital debris has a
geography.
The StoryMap helps make that geography
visible. It translates a highly technical aerospace issue into an interactive
spatial narrative that students, researchers, policymakers, and the broader
public can understand. This is the power of GIS communication: it does not
merely store data; it helps people see relationships, patterns, and
consequences.
If orbital debris remains invisible to the
public and abstract to decision-makers, it will remain difficult to
communicate, regulate, insure, and mitigate. But when we map it, we begin to
understand it as a shared environment requiring shared responsibility.
From
StoryMap to Research Innovation
Lauren’s project inspired a broader framework
that I call GEO-ORBIS: Geospatial Orbital Risk and Business Intelligence
System.
GEO-ORBIS is a proposed decision-support
framework that connects orbital-debris science with GIS, risk analysis,
economics, policy, and public communication.
1.
The Geospatial Layer
This layer answers the question: where is the
risk? It maps orbital objects, debris density, active satellites, abandoned
spacecraft, rocket bodies, and high-risk orbital zones.
2.
The Risk Layer
This layer asks: what can be damaged or
disrupted? It interprets collision exposure, conjunction risks, debris
hotspots, and orbital congestion.
3.
The Economic Layer
This layer asks: what is financially at
stake? Orbital debris increases mission risk, shortens satellite lifetimes,
raises insurance concerns, forces avoidance maneuvers, and complicates future
launches.
4.
The Policy Layer
This layer asks: what rules guide responsible
behavior? As orbital congestion increases, regulators are beginning to respond
through deorbit, mitigation, licensing, and sustainability requirements.
5.
The Communication Layer
This layer asks: how do we make people
understand and act? StoryMaps, dashboards, reports, data visualizations, and
public-facing maps become essential tools for translating science into
decisions.
Why
This Matters for Investors and Incubators
Orbital debris is a risk, but it is also a
market signal. As the number of satellites grows, demand will increase for
orbital-risk dashboards, collision-awareness tools, geospatial risk scoring,
insurance analytics, regulatory compliance support, satellite-fleet exposure
reports, public education platforms, university training modules, and
space-sustainability intelligence.
A platform such as GEO-ORBIS could serve
satellite operators, insurers, investors, regulators, research laboratories,
universities, and incubators. Its value is not in replacing existing
space-surveillance systems. Its value is in translating complex orbital
information into decision-ready intelligence.
Many decision-makers do not need raw orbital
mechanics data. They need to know where risk is concentrated, what assets are
exposed, what regulations apply, and what decisions should be made next. This
is where GIS and business intelligence can work together.
A
New Kind of Environmental Geography
We often think of environmental problems as
issues affecting forests, rivers, oceans, cities, or the atmosphere. Orbital
debris asks us to expand that thinking. Earth orbit is also an environment.
It is not natural in the traditional sense,
but it is shared. It is limited. It is increasingly crowded. And it supports
essential services for people on Earth.
This makes orbital debris similar to other
global commons problems. Like ocean plastic, air pollution, or climate change,
orbital debris is created by many actors, accumulates over time, crosses
national boundaries, and requires cooperation to manage.
The difference is that most people cannot see
it. That is why Lauren’s StoryMap is powerful. It gives visual form to a hidden
risk and helps students and the public understand that the space around Earth
is not an unlimited dumping ground.
The
Role of Students in Scientific Innovation
One of the most inspiring aspects of this
project is that it began with a student. Students often bring fresh eyes to
complex problems. In this case, Lauren Forcey used GIS and Esri StoryMaps not
just to present information, but to ask a deeper question: how can spatial
storytelling help society understand the future of orbital sustainability?
That question has scientific value. It has
educational value. It has business value. And it has public value.
As educators, we often evaluate student
projects as class assignments. But sometimes a class project opens a door to
something larger. This project does exactly that. It shows how aerospace
thinking, GIS methods, and public communication can come together to address a
real global challenge.
Why
a StoryMap Is the Right Medium
A StoryMap is not simply a map. It is a
narrative environment. It combines text, maps, images, data, and interaction.
For a topic like orbital debris, this is especially useful because the problem
is difficult to imagine.
Most people have never seen orbital debris.
They may not realize how many objects are above Earth, how fast they travel, or
how much modern society depends on satellites. A StoryMap helps solve that
problem by guiding the reader through evidence and interpretation.
It can show where debris is concentrated, why
small objects matter, how satellites are exposed, why orbital congestion is
increasing, how policy is changing, and why space sustainability affects life
on Earth.
From
Classroom Project to Public Science
The next step is to develop this work into a
broader public-science and research platform. A future version of the project
could include updated orbital-debris datasets, interactive debris-density maps,
a risk index by orbital zone, a policy dashboard, a business-intelligence layer
for investors and insurers, educational modules, and a public StoryMap series
explaining space sustainability in accessible language.
The
Larger Message
The larger message is clear: space
sustainability is Earth sustainability.
When satellites are threatened, Earth-based
systems are threatened too. Weather forecasting, navigation, disaster response,
climate monitoring, agriculture, communications, and security all depend on
orbital infrastructure.
Orbital debris may be above us, but its
consequences are around us. Lauren Forcey’s StoryMap helps reveal this
connection. It shows that GIS can play an important role in aerospace
communication. It also shows that students can produce work that matters beyond
the classroom.
Conclusion:
Making the Invisible Visible
My aerospace student Lauren Forcey’s Esri
StoryMap project demonstrates the power of geospatial storytelling to
illuminate one of the most important hidden challenges of the modern space age.
Orbital debris is invisible to most people,
but it is not harmless. It is a growing risk to satellites, space missions, the
space economy, and the services we rely on every day.
By mapping orbital debris risk, we make the
problem visible. By making it visible, we make it understandable. And by making
it understandable, we make better decisions possible.
That is the promise of this project. It is
not only about space debris. It is about how we use GIS to communicate science,
how we prepare students to solve emerging problems, and how we protect the
shared orbital environment that now supports life on Earth.
