Video: 00:07:25 Meet Copernicus Sentinel-1 – this ground-breaking mission delivers continuous, all-weather, day-and-night imaging for land, ice and maritime monitoring. Equipped with state-of-the-art C-band synthetic aperture radar (SAR), Sentinel-1 captures high-resolution data around the clock, in any weather, making it indispensable for detecting the subtle changes on Earth’s surface that remain hidden from the human eye. Sentinel-1 data serves a multitude of critical applications: from ensuring the safety and efficiency of maritime traffic, tracking sea ice and icebergs, to monitoring structural integrity and natural hazards, such as earthquakes, landslides a…

Video: 00:04:30 Explore the immense power of water as ESA’s Mars Express takes us on a flight over curving channels, streamlined islands and muddled ‘chaotic terrain’ on Mars, soaking up rover landing sites along the way. This beautiful flight around the Oxia Palus region of Mars covers a total area of approximately 890 000 km2, more than twice the size of Germany. Central to the tour is one of Mars’s largest outflow channels, Ares Vallis. It stretches for more than 1700 km2 and cascades down from the planet’s southern highlands to enter the lower-lying plains of Chryse Planitia. Billions of years ago, water surged through Ares Vallis, neighbouring Tiu Vallis, and…

Zoom into Solar Orbiter's four new Sun images, assembled from high-resolution observations by the spacecraft's PHI and EUI instruments made on 22 March 2023. The PHI images are the highest-resolution full views of the Sun's visible surface to date, including maps of the Sun's messy magnetic field and movement on the surface. These can be compared to the new EUI image, which reveals the Sun's glowing outer atmosphere, or corona. View the full article

Video: 00:02:18 At ESA, through the Advanced Research in Telecommunications Systems programme, we’re addressing solutions for when safety and security of communication services cannot be guaranteed by the terrestrial networks alone. With our programme Space systems for Safety and Security, or 4S, we are pioneering cutting-edge development of secure and resilient satellite communication systems, technologies and services to improve life on Earth. Picture a world where our critical infrastructure is protected from cyber threats, and where communication links work when the world around them doesn't. A transportation network where safety is not just a priority, but a…

As Arctic temperatures rise, marine-terminating glaciers—especially in places like Svalbard—are undergoing rapid retreat and intensified calving. The ESA-funded Space for Shore project utilises radar data from the Copernicus Sentinel-1 mission to provide precise, year-over-year insights into glacier retreat and calving intensity, particularly in areas like Kongsfjorden, where notable glaciers are experiencing significant retreat.

Video: 00:04:31 The double-satellite Proba-3 is the most ambitious member yet of ESA’s Proba family of experimental missions. Two spacecraft will fly together as one, maintaining precise formation down to a single millimetre. One will block out the fiery disc of the Sun for the other, to enable prolonged observations of the Sun’s surrounding atmosphere, or ‘corona’, the source of the solar wind and space weather. Usually, the corona can only be glimpsed for a few minutes during terrestrial total solar eclipses. Proba-3 aims to reproduce such eclipses for up to six hours at a time, in a highly elliptical orbit taking it more than 60 000 km from Earth. The two space…

Marking a major milestone in the preparation of Copernicus Sentinel-1C for its scheduled 3 December liftoff, experts have completed the critical and hazardous process of fuelling the satellite. Once in orbit, Sentinel-1C will extend the Sentinel-1 mission’s legacy, delivering radar imagery to monitor Earth’s changing environment to support a diverse range of applications and scientific research. Additionally, Sentinel-1C brings new capabilities for detecting and monitoring maritime traffic View the full article

Video: 00:06:45 Smile is the Solar wind Magnetosphere Ionosphere Link Explorer, a brand-new space mission currently in the making. It will study space weather and the interaction between the solar wind and Earth’s environment. Unique about Smile is that it will take the first X-ray images and videos of the solar wind slamming into Earth’s protective magnetic bubble, and its complementary ultraviolet images will provide the longest-ever continuous look at the northern lights. In this first of several short videos, David Agnolon (Smile Project Manager) and Philippe Escoubet (Smile Project Scientist) talk about the why and the how of Smile. You’ll see scenes of the b…

A new European Space Agency-backed study shows that the extreme heatwaves of 2023, which fuelled huge wildfires and severe droughts, also undermined the land’s capacity to soak up atmospheric carbon. This diminished carbon uptake drove atmospheric carbon dioxide levels to new highs, intensifying concerns about accelerating climate change. View the full article

Video: 00:09:09 On 12 November 2014, after a ten-year journey through the Solar System and over 500 million kilometres from home, Rosetta’s lander Philae made space exploration history by touching down on a comet for the first time. On the occasion of the tenth anniversary of this extraordinary feat, we celebrate by taking a look back over the mission's highlights. Rosetta was an ESA mission with contributions from its Member States and NASA. It studied Comet 67P/Churyumov-Gerasimenko for over two years, including delivering lander Philae to the comet’s surface. Philae was provided by a consortium led by DLR, MPS, CNES and ASI. read the article Philae’s extraordin…

ESA is taking a significant step towards creating a more digitally inclusive Europe through a new partnership that will bring internet access to the hardest-to-reach areas. Reliable connectivity has become essential in today's digital age, yet for many Europeans in rural villages, mountainous regions, and small islands, dependable internet access remains out of reach.
