Image: On Friday 18 July, His Excellency Christian Stocker, Federal Chancellor of Austria, visited ESA Headquarters in Paris receiving a tour of the site from Director General Josef Aschbacher. It was the Chancellor’s first visit to an ESA establishment following his swearing in earlier this year. Visiting the Astrolabe interpretive centre, Mr Stocker saw how Austria’s participation in ESA contributes to the goals of sustainable development and scientific excellence, and also heard how commercial space has undergone rapid development in Austria. He was accompanied by the Austrian ambassador to France, Barbara Kaudel-Jensen. Austria became ESA’s 12th Member State when it ratified the ESA Convention in December 1986 and while always strongly committed to Earth observation and space applications, Austria has recently diversified its space interests, becoming more involved in launchers, navigation and human and robotic exploration. Austrian Carmen Possnig was selected as a member of ESA’s astronaut reserve in 2022 and will commence her second phase of training in the autumn. Carmen joined the visit and enthusiastically answered questions from the assembled Austrian media. As part of Austria's innovation community, the ESA PhiLab opened last year and has a current call for proposals open until 8 October. Just last month, Austria hosted the Living Planet Symposium, which brought together 6500 members of the Earth observation community to present scientific results and plan future activities. It was supported by a citywide 'Space in the City' festival in Vienna, organised by the Federal Ministry for Innovation, Mobility and Infrastructure (BMIMI) and Urban Innovation Vienna GmbH (UIV) and demonstrating the everyday connections between citizens and space.

Video: 00:01:51 Space weather ‘reporter’ Vigil will be the world’s first space weather mission to be permanently positioned at Lagrange point 5, a unique vantage point that allows us to see solar activity days before it reaches Earth. ESA’s Vigil mission will be a dedicated operational space weather mission, sending data 24/7 from deep space. Vigil’s tools as a space weather reporter at its unique location in deep space will drastically improve forecasting abilities. From there, Vigil can see ‘around the corner’ of the Sun and observe activity on the surface of the Sun days before it rotates into view from Earth. It can also watch the Sun-Earth line side-on, giving an earlier and clearer picture of coronal mass ejections (CMEs) heading toward Earth. Radiation, plasma and particles flung towards Earth by the Sun can pose a very real risk to critical infrastructure our society relies on. This includes satellites for navigation, communications and banking services as well as power grids and radio communication on the ground. A report by Lloyd’s of London estimates that a severe space weather event, caused by such an outburst of solar activity, could cost the global economy 2.4 trillion dollars over five years. ESA’s response to this growing threat is Vigil, a cornerstone mission of the Agency’s Space Safety Programme, planned for launch in 2031. Vigil’s data will give us drastically improved early warnings and forecasts, which in turn help protect satellites, astronauts and critical infrastructure on the ground that we all depend on.

Video: 00:00:40 View of Earth as seen by ESA project astronaut Sławosz Uznański-Wiśniewski inside the seven-windowed cupola, the International Space Station's "window to the world". The European Space Agency-built Cupola is the favourite place of many astronauts on the International Space Station. It serves not only as a unique photo spot, but also for observing robotic activities of the Canadian Space Agency's robotic arm Canadarm2, arriving spacecraft and spacewalks. Sławosz was launched to the International Space Station on the Dragon spacecraft as part of Axiom Mission 4 on 25 June 2025. The 20-day mission on board is known as Ignis. During the Ignis mission, Sławosz conducted 13 experiments proposed by Polish companies and institutions and developed in collaboration with ESA, along with three additional ESA-led experiments. These covered a broad range of areas including human research, materials science, biology, biotechnology and technology demonstrations.  The Ax-4 mission marks the second commercial human spaceflight for an ESA project astronaut. Ignis was sponsored by the Polish government and supported by ESA, the Polish Ministry of Economic Development and Technology (MRiT) and the Polish Space Agency (POLSA).   View the full article

Φsat-2, a miniature satellite, has completed its commissioning and has begun delivery of science data, using algorithms to efficiently process and compress Earth observation images, as well as detect wildfires, ships, marine pollution and more. View the full article

All its parts have been built and put together. It has been wrapped in shiny gold insulating foil. Its launch is getting closer. But the Smile spacecraft had one major phase to pass before it could be certified ready for space – and it involved testing, testing and yet more testing. View the full article

Image: This image tells the story of redemption for one lonely star. The young star MP Mus (PDS 66) was thought to be all alone in the Universe, surrounded by nothing but a featureless band of gas and dust called a protoplanetary disc. In most cases, the material inside a protoplanetary disc condenses to form new planets around the star, leaving large gaps where the gas and dust used to be. These features are seen in almost every disc – but not in MP Mus’s. When astronomers first observed it with the Atacama Large Millimeter/submillimeter Array (ALMA), they saw a smooth, planet-free disc, shown here in the right image. The team, led by Álvaro Ribas, an astronomer at the University of Cambridge, UK, gave this star another chance and re-observed it with ALMA at longer wavelengths that peer even deeper into the protoplanetary disc than before. These new observations, shown in the left image, revealed a gap and a ring that had been obscured in previous observations, suggesting that MP Mus might have company after all. Meanwhile, another piece of the puzzle was being revealed in Germany as Miguel Vioque, an astronomer at the European Southern Observatory, studied this same star with the European Space Agency’s (ESA’s) Gaia mission. Vioque noticed something suspicious – the star was wobbling. A bit of gravitational detective work, together with insights from the new disc structures revealed by ALMA, showed that this motion could be explained by the presence of a gas giant exoplanet. Both teams presented their joint results in a new paper published in Nature Astronomy. In what they describe as “a beautiful merging of two groups approaching the same object from different angles”, they show that MP Mus isn’t so boring after all. [Image description: This is an observation from the ALMA telescope, showing two versions (side-by-side) of a protoplanetary disc. Both discs are bright, glowing yellow-orange objects with a diffused halo against a dark background. The right disc is more smooth and blurry looking. The left disc shows more detail, for example gaps and rings within it.] Source: ESO View the full article
