ESA’s Biomass Space Probe Set to Map Carbon in Tropical Forests

Focus Keyword: Biomass Space Probe

On April 29, 2025, the European Space Agency (ESA) is preparing to launch a groundbreaking new satellite mission known as the Biomass Space Probe. This ambitious project is designed to measure the carbon stored in some of the world’s most remote and dense tropical forests. By generating detailed 3D maps of forest structures, the probe will provide invaluable data to help combat climate change and preserve the planet’s most vital ecosystems.

Why Tropical Forests Matter

Tropical rainforests are the lungs of our planet. Spanning continents like Africa, South America, and Southeast Asia, these ecosystems play a crucial role in the global carbon cycle. It’s estimated that tropical forests absorb more than eight billion tonnes of CO₂ annually — but deforestation and degradation are reversing that benefit, releasing vast amounts of stored carbon back into the atmosphere.

Yet, studying these forests has always been a challenge. Their dense, high canopies — often rising over 40 meters tall — block light and make traditional aerial and satellite measurements nearly impossible. This is exactly what the Biomass Space Probe aims to overcome.

What Makes the Biomass Probe Unique?

The ESA’s Biomass mission uses a revolutionary P-band synthetic aperture radar — a type of long-wavelength radar that can penetrate through thick vegetation. This will allow scientists to “see” beneath the forest canopy and map the biomass — essentially weighing the forests by measuring their carbon content.

Developed by Airbus UK, the spacecraft is fitted with a massive 12-meter antenna, making it one of the most sophisticated observation tools ever launched for forest analysis. It will orbit Earth for five years, collecting vast amounts of data on how much carbon is stored, where it’s being lost, and how forest systems are changing over time.

Why This Mission Is Critical for Climate Science

Until now, scientists have relied on estimates, ground surveys, and limited remote sensing to understand forest carbon levels. The Biomass probe changes that by providing accurate, scalable, and real-time data that can be integrated into climate models.

According to the Guardian, this mission will improve our understanding of global warming impacts and inform carbon offset and conservation policies at an international scale.

NASA has also explored biomass mapping through missions like GEDI (Global Ecosystem Dynamics Investigation), which uses lidar technology to assess forest structure and carbon stocks from the International Space Station. Learn more about GEDI here.

Additionally, the United Nations’ REDD+ program supports developing countries in reducing emissions from deforestation. The ESA’s Biomass mission is expected to complement these efforts by providing precise carbon data. Visit UN-REDD for details.

AI + Space Tech = Smarter Conservation

One of the most exciting aspects of this mission is its integration with artificial intelligence. The radar data collected will be processed using machine learning algorithms to model forest structure, carbon storage, and future deforestation risk.

This combination of AI and orbital technology allows for predictive insights, enabling environmentalists and policymakers to take preemptive action rather than react to damage already done.

A Global Tool for Conservation Strategy

With its ability to measure how much carbon tropical forests are truly holding, the Biomass Space Probe has the potential to shift climate policy. Countries can gain hard data to back conservation incentives, enforce carbon offset credits more accurately, and collaborate across borders on rainforest protection efforts.

It’s not just about trees — it’s about survival. The forests in question regulate rainfall, feed biodiversity, and buffer global climate. Losing them has planetary consequences.

Public and Scientific Excitement Builds

The mission has been widely applauded by climate scientists, conservationists, and environmental advocates around the world. From national space agencies to grassroots NGOs, many are eagerly awaiting the data that Biomass will provide.

ESA’s use of advanced radar technology in this context sets a precedent for future missions focused on Earth’s biosphere — not just stars and planets.
