Launched just two months ago and still in the process of being commissioned for service, the Copernicus Sentinel-1C satellite is, remarkably, already showing how its radar data can be used to map the shape of Earth’s land surface with extreme precision. These first cross-satellite ‘interferometry’ results assure its ability to monitor subsidence, uplift, glacier flow, and disasters such as landslides and earthquakes. View the full article

After years of meticulous development, ESA’s next Earth Explorer satellite, Biomass, is ready to be packed up for transport to Europe’s Spaceport in French Guiana, where it will launch aboard a Vega-C rocket this spring. Before final preparations and shipment, media representatives had the exclusive opportunity today to see the satellite up close in the cleanroom at Airbus’ facilities in Toulouse, France.

Optical technology has the potential to revolutionise the field of positioning, navigation and timing. To drive the development of this technology, ESA has signed a contract with a consortium of European companies that will conduct a definition study (Phase A/B1) and associated critical technology predevelopment. This is the first step toward a potential in-orbit demonstrator for optical time synchronisation and ranging (OpSTAR) that will be proposed at the ESA Council at Ministerial Level in November 2025, to validate intersatellite optical links before future use in operational satellite navigation systems.

Space is not the safest place to be. During spaceflight, both devices and humans risk exposure to high levels of radiation. Without sufficient protection, instruments would malfunction, and astronauts might face serious health risks. A team of researchers from Ghent University in Belgium are testing the potential of 3D-printed hydrogels – materials that can soak up large amounts of water – to serve as highly-effective radiation shields.

In a landmark achievement, ESA successfully migrated Galileo’s Control Centres in a highly complex operation involving over 200 people from the Agency, industry and EUSPA. This milestone marked the beginning of a global operation to upgrade Galileo’s entire Ground Segment, a vast network of stations spread around the world. View the full article

Video: 00:00:40 Back in 2023, we reported on Solar Orbiter’s discovery of tiny jets near the Sun’s south pole that could be powering the solar wind. The team behind this research has now used even more data from the European Space Agency’s prolific solar mission to confirm that these jets exist all over dark patches in the Sun’s atmosphere, and that they really are a source of not only fast but also slow solar wind. The newfound jets can be seen in this sped-up video as hair-like wisps that flash very briefly, for example within the circled regions of the Sun's surface. In reality they last around one minute and fling out charged particles at about 100 km/s. The s…

Today, ESA, the Finnish government and the Finnish Meteorological Institute took the initial steps towards establishing a ‘supersite’ for Earth observation calibration and validation in Sodankylä in Finnish Lapland. Envisaged as a joint investment, this world-class site would bring benefits to both ESA, by helping to further ensure satellites deliver accurate data over high latitude environments, and to Finland by providing Finnish businesses with new opportunities to develop and test environmental sensors and technology.

Video: 00:06:40 A group of volunteers is spending two months lying in bed—with their feet up and one shoulder always touching the mattress—even while eating, showering, and using the toilet. But why? This extreme bedrest study is helping scientists understand how space travel affects the human body and how to keep astronauts healthy on long missions. Microgravity causes muscle and bone loss, fluid shifts, and other physiological changes similar to those experienced by bedridden patients on Earth. By studying volunteers here on Earth, researchers can develop better countermeasures for astronauts and even improve treatments for medical conditions like osteoporosis. …
