ESA launches Sentinel-3C and Flex satellites for climate monitoring

European Space Agency deploys two Earth observation satellites to track vegetation health and ocean conditions amid climate change.

What to know

  • ESA successfully launched Sentinel-3C and Flex satellites on September 14–15 to enhance climate and environmental monitoring for Europe.
  • Flex tracks plant photosynthesis fluorescence to measure vegetation stress and ecosystem health; Sentinel-3C monitors oceans, land use, and crop productivity to prevent food crises.
  • Social media users question the carbon footprint and ecological cost of satellite launches themselves, even as they serve climate science.

The dispute Whether the ecological and climate costs of launching and eventually deorbiting satellites outweigh their value for climate monitoring. · positions read across 2 posts and comments

Satellite launches have significant environmental and climate costs that must be weighed against their monitoring benefits.

    ESA describes missions as essential for climate understanding

    Simonetta Cheli, director of Earth Observation Programmes at the ESA, characterized the satellite missions as critical tools for addressing the climate crisis.

    “essential in helping with the climate change we are experiencing…”

  2. background

    Sentinel-3C will track ocean conditions and agricultural productivity — Sentinel-3C, part of the EU's Copernicus Earth observation program, will collect marine data including temperature, wave height, and ocean currents, plus monitor land use and land cover to optimize yields and prevent food crises.

  3. background

    Flex satellite will monitor plant health via photosynthesis fluorescence — The Flex (Fluorescence Explorer) satellite measures faint fluorescence emitted by plants during photosynthesis to assess vegetation efficiency and the impact of heat waves. It will orbit Earth 14 times daily and revisit locations every 27 days.
