The forces of rotation caused red hot masses of stones to be torn away from the Earth and to be thrown into the ether, and this is the origin of the stars.

SMOS adds long-term view on carbon stored in forests

Fri, 08/01/2025 - 5:00am

Data from ESA’s Soil Moisture and Ocean Salinity (SMOS) mission can be used to estimate how much carbon is stored in forests – and a study has improved our understanding of how reliable this proxy is and how long-term datasets from SMOS can help us to monitor this valuable resource.

A troubling shift in Europe’s forest carbon balance

Wed, 07/30/2025 - 11:00am

Europe’s forests play a crucial role in removing carbon dioxide from the atmosphere, but research led by the European Commission’s Joint Research Centre has found their capacity to absorb carbon dioxide has declined in the past decade.

Webb traces details of complex planetary nebula

Wed, 07/30/2025 - 10:00am

More than one star contributes to the irregular shape of NGC 6072 – Webb’s newest look at this planetary nebula in the near- and mid-infrared shows what may appear as a very messy scene resembling splattered paint. However, the unusual, asymmetrical scene hints at more complicated mechanisms underway, as the star central to the scene approaches the very final stages of its life and expels shells of material, losing up to 80 percent of its mass.

Greenland subglacial flood bursts through ice sheet surface

Wed, 07/30/2025 - 5:00am

Using data from several Earth-observing satellites, including ESA’s CryoSat and the Copernicus Sentinel-1 and Sentinel-2 missions, scientists have discovered that a huge flood beneath the Greenland Ice Sheet surged upwards with such force that it fractured the ice sheet, resulting in a vast quantity of meltwater bursting through the ice surface.

Highlights and liftoff of Vega-C flight VV27 from Europe’s Spaceport in French Guiana, at 23:03 local time on 25 July (03:03 BST/04:03 CEST on 26 July).

Flight VV27 was operated by Arianespace and launched Airbus’s four CO3D satellites and the French space agency CNES MicroCarb mission.

The four small satellites in the CO3D constellation (an abbreviation of the French 'Constellation Optique en 3D') are set to map the globe in three dimensions from low Earth orbit, to serve public and private sector needs.

MicroCarb is designed to map sources and sinks of carbon dioxide on a global scale. ESA coordinated and procured the launch of MicroCarb on behalf of the European Commission, as part of its In-Orbit Demonstration / In-Orbit Validation (IOD/IOV) programme.

First MetOp Second Generation satellite fuelled

Thu, 07/24/2025 - 4:56am

The journey to launch is picking up pace for Europe’s MetOp Second Generation weather satellite – which hosts the Copernicus Sentinel-5 as part of its instrument package. Specialists at Europe’s Spaceport in Kourou have completed the critical and hazardous task of fuelling the satellite, marking a major milestone in its final preparations for liftoff.

Sea-level monitoring satellite Sentinel-6B sets sail

Wed, 07/23/2025 - 6:07am

The next sea-level monitoring satellite, Copernicus Sentinel-6B, has begun its journey from Europe to the Vandenberg Space Force Base in California, where it is scheduled to launch in November. Carefully packed into a climate-controlled container, the satellite is currently crossing the Atlantic Ocean aboard the cargo ship Industrial Dolphin.

On 15 July 2025, with the splashdown of the Dragon capsule off the coast of California, the Ignis mission ended after a 20-day space journey. ESA project astronaut Sławosz Uznański-Wiśniewski from Poland, during nearly 230 orbits around Earth, completed about 120 hours of telework on the International Space Station and contributed to more than 20 experiments from his orbital office.

Following medical checks on the recovery vessel, Sławosz flew to shore by helicopter and then travelled from the United States to Germany in order to undergo a week of recovery at the European Astronaut Centre. Dozens of people gathered to give him a warm welcome at the Cologne Bonn airport.

Federal Chancellor of Austria welcomed to ESA Headquarters

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.
