Umbrella in Orbit: ESA’s BIOMASS Satellite Lifts Earth’s Green Veil, Revealing Hidden Carbon Stores and Jaw‑Dropping First Images
BIOMASS uses a fully polarimetric P-band SAR with a 70 cm wavelength to pierce through canopies and measure woody trunks where most forest carbon is stored. The 12-meter deployable reflector, shaped like an umbrella and built by L3Harris, directs radar pulses back to the sensor. The 1.25-tonne spacecraft was launched on 29 April 2025 aboard a Vega-C rocket from Kourou into a 666 km sun-synchronous orbit (flight VV26). The gold-colored reflector unfurled in orbit on 7 May 2025, marking a key commissioning milestone. First images show colour-coded maps of the Amazon, Indonesia, and the bedrock of the Sahara.
