Vandenberg Space Force Base, California, 26 August 2025 – Luxembourg successfully placed its first national Earth observation satellite, the National Advanced Optical System (NAOS), into orbit aboard a SpaceX Falcon 9 rocket. Liftoff occurred at 11:53 a.m. Pacific Time in a mission lasting just over one hour. SpaceX confirmed the deployment of NAOS and all rideshare payloads. The rocket’s first-stage booster returned to land at Vandenberg, completing its 27th mission.
Space-Based Observations Reveal Key Climate Changes in 2024
Satellite data continue to play a crucial role in understanding Earth’s changing climate. The annual State of the Climate report, published by the Bulletin of the American Meteorological Society, draws on a combination of space-based measurements, ground stations, ocean buoys, and field observations to provide a comprehensive overview of global climate conditions.
Kourou, French Guiana, 13 August 2025 – Ushering in a new era of weather and climate monitoring from polar orbit, Europe’s first MetOp Second Generation (MetOp-SG-A1) weather satellite has been launched aboard an Ariane 6 rocket from Europe’s Spaceport in Kourou, French Guiana. Liftoff occurred at 02:37 CEST (12 August, 21:37 local time), carrying the four-ton spacecraft into a polar orbit roughly 800 km above Earth.
US-French SWOT Satellite Measures Tsunami after 8.8 magnitude earthquake

United Nations/Nigeria Workshop on the International Space Weather Initiative:
Space Weather During a Moderate Solar Cycle #25
Introduction Space weather is an inherently international matter. Solar and magnetic storms affect large regions of the Earth simultaneously and equatorial ionospheric disturbances occur routinely around the world. It is therefore appropriate for the United Nations to promote improvements in space weather modelling and forecasting for the benefit of all nations.
