Ocean heat reaches record highs as El Niño looms

Global ocean surface temperatures in June hit record highs, with Copernicus Climate Change Service recording about 20.86°C and Copernicus Marine Service about 21°C outside polar regions, signaling a potential new warming phase as El Niño approaches; scientists say the warming is driven by greenhouse gas emissions and could bring more temperature records and heat waves in the US and Europe, where over 46 million people are under extreme heat alerts and Europe has logged thousands of heat-related excess deaths.

Galileo’s Hidden Annotations Reframe His Leap from Ptolemy to Copernicus

An Italian historian has found a 1551 copy of Ptolemy’s Almagest with notes in likely Galileo’s handwriting, dated around 1590 and confirmed by handwriting experts, suggesting Galileo used Ptolemy’s mathematical framework to develop Copernican ideas rather than reject ancient wisdom outright; the find is to be studied further in the Journal for the History of Astronomy and highlighted by the National Central Library of Florence.

Sentinel-2A Captures Earth After Dark in Nighttime Imaging Trial

ESA’s daylight-focused Sentinel-2A was activated during night passes and produced unexpectedly clear images of gas flares in Qatar and Iraq, a wildfire in India, and fishing boats off South Korea, demonstrating potential for nighttime Earth observation and informing future mission requirements as the Copernicus program progresses with additional Sentinel-2 satellites.

Earth nears 1.5C barrier as 2025 is third-warmest year on record

Copernicus data show global temperatures about 1.4C above pre-industrial levels, with 2025 the third-warmest year on record at about 1.47C; 2024 remains the hottest year at around 1.6C, and the three-year stretch has briefly exceeded 1.5C, indicating the world is on pace to breach the Paris Agreement’s 1.5C target this decade due to greenhouse gas emissions and intensified heat in Europe and polar regions.

Vega-C Rocket Triumphantly Returns with Successful Launch

Europe's Vega-C rocket successfully launched from French Guiana, marking its return after a two-year hiatus due to a previous failure. The rocket carried the Sentinel-1C satellite for the EU's Copernicus Earth observation program, which aims to enhance radar imagery for environmental monitoring. The Vega-C, an upgrade from the original Vega, offers increased payload capacity and cost efficiency. This launch is crucial for Europe's space access, especially after the cessation of using Russian Soyuz vehicles and delays in the Ariane 6 program.

Vega-C Set for Comeback with Sentinel-1C Launch

Arianespace is set to launch the Vega-C rocket on December 5, 2024, marking its return to flight after a failed mission in 2022. The launch will deploy the Sentinel-1C satellite, part of the Copernicus Earth science program, from Kourou, French Guiana. This mission is crucial for Arianespace as it transitions from older rockets to new models like the Ariane 6 and Vega-C, amid geopolitical and technical challenges. Sentinel-1C will enhance radar imaging capabilities and introduce new features like AIS receivers for ship tracking.

Vega-C Rocket Set for Return with Sentinel-1C Launch

Europe's Vega-C rocket is set to return to flight for the first time since a 2022 mission failure, launching the Copernicus Sentinel-1C satellite from Kourou, French Guiana. This mission aims to replace the inoperable Sentinel-1B and complete a dual-satellite constellation with Sentinel-1A for comprehensive Earth observation. The launch marks a significant step for ESA and Avio, Vega-C's primary designer, as they continue to innovate with plans for an upgraded Vega-E rocket.

Vega-C Launch Delayed for Precautionary Checks, Now Set for Dec. 4

The Vega-C rocket's return to flight has been delayed by a day for additional precautionary checks, as announced by Arianespace. The mission, VV25, will launch the Sentinel-1C satellite into a Sun-synchronous orbit, marking the first Vega-C flight since a failed launch in December 2022. The delay is part of efforts to ensure maximum flight worthiness, following extensive tests on the rocket's upper stage. The Sentinel-1C is part of the Copernicus program, providing crucial Earth observation data.
