ESA Biomass Satellite Mission

In News:

The Biomass Mission is a new Earth observation mission by the European Space Agency (ESA) aimed at enhancing our understanding of the global carbon cycle through accurate forest biomass measurements.

Launch Details:

  • Rocket: Vega-C
  • Launch Site: Europe’s Spaceport, French Guiana
  • Orbit: Sun-Synchronous Orbit (SSO) at an altitude of ~666 km
  • Scheduled Launch Date: 29 April 2025 (subject to final checks)

Key Features:

  • First satellite to use P-band radar (long-wavelength synthetic aperture radar).
  • Capable of penetrating dense forest canopies to scan tree trunks, branches, and stems — where most of a tree’s carbon is stored.
  • Will generate 3D maps of the world’s tropical forests.

Mission Objectives:

  • Measure above-ground forest biomass and forest height.
  • Create five global biomass maps over its five-year mission.
  • Monitor changes in forests to assess their role in carbon sequestration and climate regulation.

Scientific Importance:

  • Forests absorb ~8 billion tonnes of CO? annually and are often referred to as "Earth’s green lungs."
  • By analyzing forest carbon storage and changes, the mission will contribute significantly to:
    • Monitoring climate change
    • Supporting carbon accounting
    • Improving air quality assessments

Phases of the Mission:

  1. Initial Phase: Produces detailed 3D forest maps globally.
  2. Second Phase: Generates global estimates of forest height and biomass.

Relevance to Climate Action:

  • Helps in quantifying carbon uptake and release.
  • Supports global climate models and carbon budgeting.
  • Aids in policy-making for sustainable forest management.
