Astronomers looking into the early Universe have made a surprising discovery using the NASA/ESA/CSA James Webb Space Telescope. Webb’s spectroscopic capabilities, combined with its infrared sensitivity, have uncovered a cluster of massive galaxies in the process of formation around an extremely red quasar. The result will expand our understanding of how galaxies in the early Universe coalesced into the cosmic web we see today.

Watch the replay of our Q&A with the media to learn about the outcomes of the 310th session of the ESA Council. Updates are provided on the ambitious package presented by ESA for the 22/23 November ESA Ministerial Meeting in Paris, but also on the further expansion of ESA memberships, the future of ExoMars, Space Transportation and the overall, delicate economic situation.

After months of effort, astronomers have succeeded in capturing the momentary shadow cast by the Didymos asteroid, from tens of million km away as it passed in front of far-distant stars – a feat of observation only made possible when both the trajectory of the asteroid and the precise location of the stars are known. Even in that case, to have a chance of success, several observers had to be placed in meticulously predicted locations across the path of the shadow, to glimpse the fleeting fading of the star within just a fraction of a second.

ESA’s Navigation Directorate is planning a new satellite whose results will enable the generation of an updated global model of Earth – the International Terrestrial Reference Frame, employed for everything from land surveying to measuring sea level rise – with an accuracy down to 1 mm, while tracking ground motion of just 0.1 mm per year. This improvement, at a stroke, will have a major impact in multiple navigation and Earth science applications, including enhancing the precision of the Galileo navigation system. This mission, called GENESIS, is being proposed to ESA’s Council Meeting at Ministerial Level next month.

Ariane 6, the new heavy-lift launch system being developed by the European Space Agency, will make its inaugural flight as soon as the fourth quarter of 2023. Briefing media gathered at ESA’s Paris Bertrand headquarters on 19 October, Director General Joseph Aschbacher said sufficient progress had been made over the past several months to anticipate a Q4 2023 first flight, pending the realization of three key milestones before April next year.

The NASA/ESA/CSA James Webb Space Telescope has captured a lush, highly detailed landscape – the iconic Pillars of Creation – where new stars are forming within dense clouds of gas and dust. The three-dimensional pillars look like majestic rock formations, but are far more permeable. These columns are made up of cool interstellar gas and dust that appear – at times – semi-transparent in near-infrared light.

Watch the replay of Samantha’s first news conference in Europe after almost six months of living and working on board the International Space Station. Samantha talks from ESA’s European Astronaut Centre in Cologne, Germany. Her Minerva mission came to an end last week and she and her colleagues from Crew-4 splashed down off the coast of Florida on 14 October at 22:55 CEST.

After a two-week voyage across the Atlantic Ocean, the ship transporting the first Meteosat Third Generation satellite docked at Pariacabo in French Guiana and the precious cargo unloaded. Now safe and sound in one of the spaceport’s cleanrooms, satellite engineers will ready it for liftoff on an Ariane 5 rocket in December. Once in geostationary orbit, this new satellite, which carries two new extremely sensitive instruments, promises to further bolster Europe's leadership in weather forecasting.

The Ariane 6 launch pad at Europe’s Spaceport in French Guiana now hosts for the first time a fully assembled example of ESA’s new heavy-lift rocket, following the addition of an upper composite to the core stage and four boosters already in place. The upper composite – consisting of two half-fairings and a payload mock-up with the structural adapter needed to join it to the core stage – made the 10 km trip from the encapsulation building to launch pad on 12 October.

In October 2022, ESA Space Shop opened its first temporary concept store on one of Europe’s busiest shopping streets. Located in Rome’s city centre, the first physical ESA Space Shop outside an ESA establishment aims to bring ESA and its space missions closer to the general public. For a period of three months only, the store offers a mix of cosmic fashion, space fun and official ESA merchandise.

Seeing how a spacecraft dies

ESA’s Mars Express has captured the rare moment of Mars’ small moon Deimos passing in front of Jupiter and its four largest moons ­– the focus of ESA’s upcoming Jupiter Icy Moons Explorer launching next year. Celestial alignments like these enable a more precise determination of the martian moons’ orbits.
