Image: Group photo taken at the General Assembly on Defence, Space and Cybersecurity, held on Friday 12 September 2025, at ESRIN, ESA’s Centre for Earth Observation Programmes in Italy. The event was organised by the European Parliament and the European Commission, in collaboration with the European Space Agency, to promote dialogue between European and national decision-makers and industry leaders. Representatives from major European entities debated the future of the European Union, which is facing unprecedented challenges since the postwar period, in an increasingly complex geopolitical context. Participants examined Europe’s needs in key sectors such as space, cybersecurity, and defence, within the broader context of the Atlantic Alliance. Acting at the European level, as demonstrated by projects like Galileo, EGNOS, and Copernicus, not only brings extraordinary added value in terms of innovation, industrial competitiveness, economies of scale, and spending efficiency, but also strengthens Europe’s strategic autonomy, the security of its citizens, and the protection of its critical infrastructure. The group included experts from major European entities, including: Andrius Kubilius, European Commissioner for Defence and Space; Adolfo Urso, Italian Minister of Enterprises and Made in Italy; Matteo Piantedosi, Italian Minister of the Interior; Gen. B. Luigi Vinciguerra, Brigade General of the Guardia di Finanza – Head of the III Operations Department, General Command; Josef Aschbacher, Director General of the European Space Agency; Simonetta Cheli, Director of Earth Observation Programmes and Head of ESRIN; Carlo Corazza, Head of the European Parliament Office in Italy; Ammiraglio Giuseppe Cavo Dragone, Chairman of the NATO Military Committee; Teodoro Valente, President of the Italian Space Agency (ASI); Hans de Vries, Chief Cybersecurity and Operations Officer (COO) - ENISA; Fabio di Stefano, Communications at the European Parliament in Italy.

The fourth satellite for the Copernicus Sentinel-1 mission, Sentinel-1D, has arrived at Félix Eboué airport, the main airport in French Guiana. From there the spacecraft, safely stored in its protective casing, will be transported to launch preparation facilities at the European Spaceport in Kourou. View the full article

The European Space Agency’s Plato spacecraft has safely arrived at ESTEC, ESA’s technical heart in the Netherlands. There, engineers will complete the spacecraft by connecting its solar panels and sunshield, and carry out a series of critical tests to confirm that Plato is fit for launch and ready for its planet-hunting mission in space.

Following the announcement of the upcoming launch of LEO-PNT’s first satellites, ESA has now unveiled the name of the mission. Celeste, as it has been officially designated, will test the potential of a new, low Earth orbit layer of satellites to enhance Galileo’s resilience and complement its capabilities.

For this new Picture of the Month feature, the NASA/ESA/CSA James Webb Space Telescope has provided a fantastic new view of IRAS 04302+2247, a planet-forming disc located about 525 light-years away in a dark cloud within the Taurus star-forming region. With Webb, researchers can study the properties and growth of dust grains within protoplanetary discs like this one, shedding light on the earliest stages of planet formation. View the full article

Video: 00:09:30 In Tenerife, Spain, stands a unique duo: ESA’s Izaña-1 and Izaña-2 laser-ranging stations. Together, they form an optical technology testbed of the European Space Agency that takes the monitoring of space debris and satellites to a new level while maturing new technologies for commercialisation. Space debris is a threat to satellites and is rapidly becoming a daily concern for satellite operators. The Space Safety Programme, part of ESA Operations, managed from ESOC in Germany, helps develop new technologies to detect and track debris, and to prevent collisions in orbit in new and innovative ways. One of these efforts takes place at the Izaña station in Tenerife. There, ESA and partner companies are testing how to deliver precise orbit data on demand with laser-based technologies. The Izaña-2 station was recently finalised by the German company DiGOS and is now in use. To perform space debris laser ranging, Izaña-2 operates as a laser transmitter, emitting high-power laser pulses towards objects in space. Izaña-1 then acts as the receiver of the few photons that are reflected back. The precision of the laser technology enables highly accurate data for precise orbit determination, which in turn is crucial for actionable collision avoidance systems and sustainable space traffic management. With the OMLET (Orbital Maintenance via Laser momEntum Transfer) project, ESA combines different development streams and possibilities for automation to support European industry with getting two innovative services market-ready: on-demand ephemeris provision and laser-based collision avoidance services for end users such as satellite operators. A future goal is to achieve collision avoidance by laser momentum transfer, where instead of the operational satellite, the piece of debris will be moved out of the way. This involves altering the orbit of a piece of space debris slightly by applying a small force to the object through laser illumination. The European Space Agency actively supports European industry in capitalising on the business opportunities that not only safeguard our satellites but also pave the way for the sustainable use of space.

According to the newly released 35th State of the Climate report, 2024 saw record highs in greenhouse gas concentrations, global land and ocean temperatures, sea levels, and ocean heat content. Glaciers also suffered their largest annual ice loss on record. Data records from ESA’s Climate Change Initiative helped underpin these findings. View the full article

The European Space Agency’s Jupiter Icy Moons Explorer (Juice) is on track for its gravity-assist flyby at Venus on 31 August, following the successful resolution of a spacecraft communication anomaly that temporarily severed contact with Earth. The issue, which emerged during a routine ground station pass on 16 July, temporarily disrupted Juice’s ability to transmit information about its health and status (telemetry). Thanks to swift and coordinated action by the teams at ESA’s European Space Operations Centre (ESOC) in Darmstadt, Germany, and Juice’s manufacturer, Airbus, communication was restored in time to prepare for the upcoming planetary encounter.
