ESA has released its new Earth Observation Science Strategy, Earth Science in Action for Tomorrow’s World. Responding to the escalating threats from climate change, biodiversity loss, pollution and extreme weather and the need to take action to address these threats, this forward-looking strategy outlines a bold vision for Earth science through to 2040.

ESA’s Jupiter Icy Moons Explorer (Juice), is on an epic eight-year journey to Jupiter. This first episode of ‘The journey of Juice’ tells the story of Juice’s first months in space, from its launch on 14 April 2023 to its lunar-Earth gravity assist (LEGA for short) in August 2024. This flyby was not only the first double gravity assist manoeuvre of its kind, it was also a perfect opportunity to test out the spacecraft’s cameras and science instruments.

Solar wind is a never-ending stream of charged particles coming from the Sun. Rather than a constant breeze, this wind is rather gusty. As solar wind particles travel through space, they interact with the Sun's variable magnetic field, creating chaotic and fluctuating motion known as turbulence.

Image: On 20 September, the Copernicus Sentinel-2C satellite captured its first stunning image of the Moon, achieved by rolling the satellite sideways in a unique manoeuvre. Although Sentinel-2C is primarily designed for Earth observation, this image – intended for calibration and cross-mission comparisons – exceeded expectations.

Looking deep into the early Universe with the NASA/ESA/CSA James Webb Space Telescope, astronomers have found something unprecedented: a galaxy with an odd light signature, which they attribute to its gas outshining its stars.

Over the nearly 70 years of spaceflight, about 10 000 intact satellites and rocket bodies have reentered the atmosphere with many more to follow. Yet for such a ubiquitous event, we still lack a clear view on what actually happens to a satellite during its fiery last moments.

There’s a mystery out there in deep space – and solving it will make Earth safer. That’s why the European Space Agency’s Hera mission is taking shape – to go where one particular spacecraft has gone before.

The Sentinel-1B satellite, the second satellite of the Copernicus Sentinel-1 mission, completed its disposal process – which included lowering its orbit and passivating its systems to ensure re-entry into Earth’s atmosphere within 25 years.

On 18–19 September, Europe’s space industry from start-up companies to large system integrators gathered at ESA–ESTEC in the Netherlands for Industry Space Days 2024.

XRISM revealed the structure, motion and temperature of the material around a supermassive black hole and in a supernova remnant in unprecedented detail. Astronomers presented the first scientific results of the new X-ray telescope today, less than a year after the telescope’s launch.

Just a month after its launch, ESA’s Arctic Weather Satellite has already delivered its first images, notably capturing Storm Boris, which has been wreaking havoc across central Europe. 

The European Galileo satellite navigation system keeps growing: a new pair of satellites has joined the constellation after a journey on a Falcon 9 rocket, launched from the Kennedy Space Center in Florida on 18 September at 00:50 CEST (17 September 18:50 local time).

From the arrival of the Earth obversation satellite Sentinel-2C in July 2024 and the first fit-check to launch from Europe’s Spaceport in French Guiana, this timelapse shows how the third Sentinel-2 satellite was prepared for launch. The last Vega rocket, flight VV24, lifted off on 5 September at 03:50 CEST (4 September 22:50 local time).
