The Future of Space-Based Communication
How satellites carry phone, TV, internet and data signals today, from geostationary to low Earth orbit, and the directions the technology may take next.
Space and Science
Space Communication and Navigation
Satellites that connect, guide and are affected by space weather.
The Challenges of Space Weather
Solar flares, coronal mass ejections and geomagnetic storms can disturb satellites, radio links and power grids. Here is how, and why forecasting them is hard.
The Challenges of Space-Based Communication in Remote and Disaster-Prone Areas
Why satellite links matter when floods, earthquakes and storms knock out ground networks, and what makes keeping them working so difficult in practice.
The Challenges of Space-Based Communication in Remote and Disaster-Prone Areas for a Sustainable Future
Affordability, equipment lifetimes and long-term access: what it takes for satellite connectivity to serve offline communities in a lasting, sustainable way.
The Challenges of Space-Based Communication in Remote Areas
Why remote regions often lack coverage and what practical limits, from geometry and weather to cost and power, shape reaching them from orbit.
The Importance of Space-Based Navigation Systems for Emergency Response
How satellite navigation helps rescuers find people, route vehicles and coordinate crews during emergencies, and where its limits lie.
The Importance of Space-Based Navigation Systems for Emergency Response and Global Safety
Beyond rescues, satellite positioning and timing support aviation, shipping and critical infrastructure. Here is what depends on it and what happens if signals fail.
The Importance of Space-Based Navigation Systems for Emergency Response and Global Safety for a Sustainable Future
A long-term look at how satellite positioning can help rescuers coordinate disaster relief, and what makes those systems resilient over the coming decades.
The Importance of Space-Based Research in Understanding the Effects of Space Weather
What space weather is, from the solar wind to flares and geomagnetic storms, and why spacecraft observations are essential for understanding its effects on Earth.
The Importance of Space-Based Research in Understanding the Effects of Space Weather and Climate Change
Space weather and climate change are different things. Learn how they differ, what satellites measure for each, and where the research overlaps.
