A new investigation by an international team of astronomers using data from the NASA/ESA/CSA James Webb Space Telescope into K2-18 b, an exoplanet 8.6 times as massive as Earth, has revealed the presence of carbon-bearing molecules including methane and carbon dioxide. The discovery adds to recent studies suggesting that K2-18 b could be a Hycean exoplanet, one which has the potential to possess a hydrogen-rich atmosphere and a water ocean-covered surface.

In a significant leap forward for meteorology, the preliminary data obtained by Meteosat Third Generation’s two instruments, the Flexible Combined Imager (FCI) and the Lightning Imager (LI), were successfully combined today for the first time – highlighting their complementary capabilities. This first set of animations gives us a preview of the system’s future impact.
ESA satnav receiver vans – driving between the busy heart of Rotterdam, quiet countryside, and the Agency’s ESTEC technical centre – have confirmed that Galileo signals now provide a first position fix more rapidly, while also offering improved robustness in challenging environments and streamlined access to time information.
ESA is testing kombucha cultures, famous for their fermentative properties and potential health benefits, to assess their resilience in space. These cultures hold great promise for supporting humans on the Moon and Mars.

As of 1 September 2023, Sławosz Uznański joined ESA as a project astronaut anticipating flying on a future space mission.
ESA astronaut Andreas Mogensen will film thunderstorms and lightning shooting up towards space as part of the climate science of the Huginn mission.
Scientists have used Solar Orbiter’s EUI camera in a new mode of operation to record part of the Sun’s atmosphere at extreme ultraviolet wavelengths that has been almost impossible to image until now. This new mode of operation was made possible with a last-minute ‘hack’ to the camera and will almost certainly influence new solar instruments for future missions.

On 5 September 2023, teams from France’s space agency CNES and Arianegroup under the lead of ESA carried out a complete Ariane 6 launch sequence on its launch pad at Europe’s spaceport in French Guiana. The test ended with a hot-fire of the launcher’s core stage and startup of the Vulcain 2.1 engine.
As quantum technology continues to shape our future, quantum entanglement remains a crucial element in unlocking valuable space applications, but how robust is it?

On 1 September 2023 ESA’s all-new Ariane 6 launch vehicle fired its two upper stage engines to simulate the way they will have to operate together at German aerospace agency DLR’s engine test centre in Lampoldshausen, Germany. The test – of the new Vinci engine and a smaller Auxiliary Power Unit (APU) – took place on a purpose-built test bench.
Validation testing continues for ESA’s all-new Ariane 6 launch vehicle, with firing of its two upper stage engines to simulate the way they will have to operate together during a flight.
