Planet Earth, Digitized: Can ESA’s Virtual Twin Save Us?

This week, Simonetta Cheli, Director of Earth Observation Programs at the European Space Agency (ESA), joins Markus to dive into one of the most ambitious and groundbreaking projects of our time: building a digital twin of our planet. Through Destination Earth (DestinE), ESA is creating a dynamic, real-time model of Earth—a tool designed to simulate future scenarios, test the impact of human decisions, and ultimately help us better care for our fragile world.

Quotable Insights

• “We’re giving Earth a voice. Our satellites are the planet’s way of telling us what’s happening—and what’s coming next.” – Simonetta Cheli
• “We don’t need more data to know we must act. We need to use the data we already have to make change visible and urgent.”
• “Europe is a world leader in Earth observation—both in technology and in making data available for all.”
