Tagline: When a forest whispers, even space must listen.

🛰️ Intro

The European Space Agency (ESA) is preparing to launch the Biomass mission on April 29, 2025, a major leap in forest mapping and carbon cycle analysis.
This satellite will pierce the canopies, capturing unseen layers of life—and loss—beneath the forest green.

🔍 Key Highlights

🌲 Mission Overview

• Uses P-band Synthetic Aperture Radar (SAR)
• Operates at 435 MHz, capable of penetrating forest canopies
• Generates 3D maps of global forests
• Focus: Biomass estimation, carbon storage, forest height, change detection
• Orbit: Low Earth Orbit | Duration: 5 years

🌿 Why It Matters

• Forests absorb ~16 billion metric tonnes of CO₂ annually
• Forest loss: 3.7 million ha of tropical forests vanished in 2023
• Forests contribute to climate resilience, carbon sinks, biodiversity
• Biomass data critical for climate modeling and global emission policies

❄️ Broader Scientific Objectives

• Monitor ice sheet dynamics in Antarctica
• Map terrain under dense vegetation
• Improve understanding of Earth’s ecological systems

🧠 Concept Explainer: Why This Matters

You cannot save what you cannot measure.
Forests, long romanticized in literature, must now be rendered in frequency and form.
ESA’s Biomass mission makes trees visible in the dimension that matters most—carbon.

💭 A Thought Spark — by IAS Monk

“What the eye cannot count,
a satellite sees—
not just trees,
but the breath of Earth
hidden in their stillness.”
