ESA observations of interstellar comet 3I/ATLAS
The European Space Agency (ESA) reacted promptly to the discovery of comet 3I/ATLAS on 1 July 2025. Soon after they were alerted to its existence by automated detection systems, ESA astronomers began using ground-based telescopes in Hawaii, Chile, and Australia to monitor its progress.
Since then, the comet has been observed by space telescopes close to Earth, including the NASA/ESA Hubble Space Telescope and the NASA/ESA/CSA James Webb Space Telescope.
In the coming months, ESA will turn interplanetary voyagers such as Mars Express, ExoMars Trace Gas Orbiter and the Jupiter Icy Moons Explorer (Juice) in the direction of the comet to make further
Galileo daughter mission named Celeste to strengthen navigation resilience
Following the announcement of the upcoming launch of its first satellites, ESA has officially named the Low Earth Orbit Positioning Navigation Timing (LEO-PNT) mission Celeste. The new program will test how a low Earth orbit layer of satellites can reinforce the resilience of Europe's Galileo system and extend its capabilities.
Galileo and its sister augmentation service EGNOS have become Limited safe carbon storage could lower warming by less than 1 degree
A new study led by the International Institute for Applied Systems Analysis (IIASA) has mapped safe underground storage areas for carbon dioxide and found that their practical use would only reduce global warming by about 0.7C. This figure is nearly ten times lower than earlier industry-based projections of 6C, which included storage in high-risk locations where carbon injection could trigger ea Hidden chemistry of Earth core revealed through freezing process
A new study by researchers from Oxford, Leeds, and University College London has uncovered fresh insights into Earth's core chemistry by showing how crystallisation became possible millions of years ago. Published in Nature Communications, the research indicates that Earth's core required 3.8% carbon content to begin freezing.
This finding suggests that carbon is more abundant in the core AI powered SAR imagery analysis tool launched by SATIM and ICEYE
SATIM and ICEYE have jointly introduced Detect and Classify, a product designed to automate analysis of Synthetic Aperture Radar (SAR) satellite imagery. The system identifies vessels, aircraft, and vehicles with accuracy exceeding 90 percent, reducing dependence on manual review and enabling defense and security organizations to act more quickly.
The product integrates ICEYE's high resolu Second Meteosat Third Generation Imager completes thermal testing ahead of Ariane 2 launch
The second Meteosat Third Generation Imager, MTG-I2, has cleared a key milestone in its preparation for launch after completing thermal vacuum testing at Thales Alenia Space's cleanroom facilities in Cannes, France. The satellite endured extreme simulated space temperatures from -180C to +150C, verifying its resilience in the geostationary environment.
