The European Space Agency confirmed a security breach involving unclassified data from science servers, with reports suggesting the leak included source code, confidential documents, and system credentials, potentially affecting the Ariel exoplanet study mission; ESA is investigating and has taken measures to secure affected systems.
In 2029, asteroid Apophis will pass within 32,000 km of Earth, prompting ESA and JAXA to collaborate on the Ramses mission to study its response to Earth's gravity, aiming to improve planetary defense techniques and demonstrate international cooperation in space exploration.
ESA's JUICE mission captured images of the active interstellar comet 3I/ATLAS as it approached the outer Solar System, revealing its bright coma and two tails, with full data expected in February 2026 to provide insights into the comet's composition and origins.
European orbiter captures the most detailed images of Mars' sunset, revealing layered atmospheric structures, particle sizes, and color variations that provide insights into the planet's climate and atmospheric composition, with plans to monitor these layers over time.
A large butterfly-shaped impact crater on Mars, created by a low-angle asteroid collision, shows signs of having been influenced by water, providing insights into the planet's watery past and impact history.
ESA has been conducting a 20-year study at Concordia station in Antarctica, where a medical doctor lives for 13 months to research the psychological and physiological effects of extreme isolation and environment, providing insights relevant to space missions beyond Earth.
A new true-color mosaic of Mars, created from 20 years of data by ESA's Mars Express, offers the most accurate visual representation of the planet's surface, revealing nuanced colors and geological features that challenge previous exaggerated red portrayals, and providing valuable scientific insights into Mars' mineral diversity and history.
The 'Eye of the Sahara,' or Richat Structure, is a 50-kilometer-wide geological formation in Mauritania, visible from space and formed by ancient geological uplift and erosion. Recent satellite imagery from ESA reveals its layered sedimentary rocks, signs of erosion, and some desert life, providing valuable insights into Earth's geological history and ecosystem, showcasing ESA's role in Earth observation.
The European Space Agency has introduced a space environment health index to assess the long-term impact of space debris, revealing that Earth's orbit is in serious crisis with levels four times above the safe threshold, emphasizing the urgent need for debris mitigation and sustainable space practices to prevent future chaos and ensure the viability of space activities.
The European Space Agency is testing a new space food made from microbes, air, and urine called Solein aboard the ISS, aiming to develop sustainable nutrition for long-duration space missions to the Moon and Mars, with the goal of making it a primary protein source by 2035.
A rare meteoroid impact on Mars near Apollinaris Mons caused dust avalanches and new surface streaks, captured by ESA's ExoMars orbiter, highlighting that most slope streaks are driven by wind and dust rather than impacts, with implications for understanding Mars' current and past environment.
Several upcoming missions to Venus are planned for the next decade, including NASA's DAVINCI and VERITAS, ESA's Envision, Rocket Lab's Venus Life Finder, and India's Venus Orbiter Mission, aiming to study Venus's atmosphere, surface, and geological history, despite some missions facing potential cancellations due to budget constraints.
Ólafur Waage successfully ported the classic game Doom to the ESA's OPS-SAT satellite by hacking its onboard systems and using its camera to capture gameplay, marking a notable achievement in orbital computing experiments and demonstrating innovative ways to utilize satellite hardware.
Europe's ESA conducted its most extreme space weather simulation to test responses to a solar superstorm similar to the 1859 Carrington Event, revealing that no spacecraft would survive such an event and highlighting the need for improved monitoring and preparedness for future solar storms.
The European Space Agency (ESA) has introduced a Space Environment Health Index to quantify the impact of human activities on Earth's orbital environment, highlighting that current space debris levels are four times higher than the sustainability threshold and emphasizing the need for stronger mitigation efforts to ensure long-term space sustainability.
