The European Space Agency's presence in Spain is set to be strengthened, while more than a dozen contracts with Spanish industry were signed on Thursday.

No communication or navigation, faulty electronics and collision risk. At ESA’s mission control in Darmstadt, teams faced a scenario unlike any before: a solar storm of extreme magnitude. Fortunately, this nightmare unfolded not in reality, but as part of the simulation campaign for Sentinel-1D, pushing the boundaries of spacecraft operations and space weather preparedness.

Video: 00:05:04 English ESA Open Day 2025: An Unforgettable Journey Through Space Science at ESACOn 4 October 2025, the European Space Agency opened the doors of ESAC – the European Space Astronomy Centre near Madrid – for an inspiring day of discovery. Visitors had the opportunity to explore ESA’s window to the Universe, where missions studying our Solar System, the Milky Way and the distant Universe are operated and analysed.Throughout the day, guests met ESA scientists and engineers, learned about missions such as Gaia, XMM-Newton, and JUICE, and experienced hands-on activities that brought the wonders of astrophysics and planetary science to life. Interactive exhibits, talks, and guided tours showcased how ESA’s science missions are expanding our understanding of the cosmos.More than two thousand participants of all ages enjoyed an unforgettable day filled with curiosity, innovation, and a shared passion for exploring the Universe.Spanish Día de Puertas Abiertas de la ESA 2025: Un viaje inolvidable por la ciencia espacial en ESACEl 4 de octubre de 2025, la Agencia Espacial Europea (ESA) abrió las puertas de ESAC – el Centro Europeo de Astronomía Espacial, cerca de Madrid – para una jornada inspiradora dedicada al descubrimiento. Los visitantes tuvieron la oportunidad única de adentrarse en el corazón del programa científico de la Agencia Espacial Europea, la ventana de la ESA al Universo, donde se operan y analizan misiones que estudian nuestro Sistema Solar, la Vía Láctea y el espacio profundo.Charlas, exposiciones y visitas guiadas mostraron cómo las misiones científicas de la ESA amplían nuestro conocimiento del cosmos. A lo largo del día, los asistentes pudieron conocer a científicos e ingenieros de la ESA, descubrir misiones como Gaia, XMM-Newton y JUICE, y participar en actividades interactivas que acercaron la astrofísica y la ciencia planetaria al público de todas las edades. Más de dos mil personas disfrutaron de una jornada inolvidable y llena de curiosidad, innovación y pasión por explorar el Universo.

Video: 00:01:33 Friday the 13th of April 2029 will be our lucky day.Apophis, a 375-metre-wide asteroid, will safely pass Earth at a distance of less than 32 000 kilometres. For a few hours, Apophis will be closer than satellites in geostationary orbit and visible to the naked eye from Europe and Africa.Space agencies have sent a number of spacecraft to asteroids, but we have never had a mission at an asteroid as it sweeps past a planet. This grand natural experiment offers a unique opportunity to study in real time how an asteroid responds to a strong external force – and the European Space Agency aims to have a front-row seat.To this end, ESA’s Space Safety Programme has proposed the Rapid Apophis Mission for Space Safety (Ramses). If approved, Ramses would launch a year ahead of the Apophis flyby, travelling through space to rendezvous with the asteroid months before its encounter with Earth.Ramses would use a suite of scientific instruments to measure Apophis’s size, shape, composition, rotation and trajectory as it is pulled and stretched by Earth’s gravity. It wouldalso deploy two smaller spacecraft at the asteroid to study Apophis up-close.Apophis poses no danger to Earth during the flyby, but an asteroid of this size passes thisclose to our planet only once every roughly seven thousand years. By seizing this exceptionally rare opportunity to study an asteroid before, during, and after a planetary encounter, Ramses would help us prepare for the day that we may need to deflect a hazardous object on a collision course with Earth.A cornerstone of the Planetary Defence segment of ESA’s Space Safety Programme, Ramses would demonstrate Europe’s ability to rapidly design, launch and operate a mission to an asteroid of high importance.When the world looks up to see Apophis passing overhead, Ramses could be flying alongside, uncovering the secrets of the Solar System’s ancient building blocks, and helping us learn how to protect our planet from any that come too close for comfort.
