Following its unanimous approval by ESA Council on 17 March, the Association Agreement between ESA and the Slovak Republic was signed on 14 June at ESA ESTEC in Noordwijk, The Netherlands.

We have now discovered 30 039 near-Earth asteroids in the Solar System – rocky bodies orbiting the Sun on a path that brings them close to Earth’s orbit. The majority of these were discovered in the last decade, showing how our ability to detect potentially risky asteroids is rapidly improving.

A new image from the NASA/ESA/CSA James Webb Space Telescope reveals a remarkable cosmic sight: at least 17 concentric dust rings emanating from a pair of stars. Located just over 5000 light-years from Earth, the duo is collectively known as Wolf-Rayet 140. Each ring was created when the two stars came close together and their stellar winds (streams of gas they blow into space) met, compressing the gas and forming dust. The stars’ orbits bring them together about once every eight years; like the rings of a tree’s trunk, the dust loops mark the passage of time.

The ESA-led Solar Orbiter mission arrives at its next close approach to the Sun on 12 October 2022 at 19:12 UTC (21:12 CEST). This sequence of images shows the progress of the ESA/NASA spacecraft as it heads inwards on its voyage of discovery. The sequence begins on 20 September and finishes on 10 October.

The kinetic impact of NASA’s DART spacecraft with the Dimorphos asteroid around its larger Didymos parent body has succeeded in shifting its orbit, meaning humankind’s first planetary defence test has been successful. Observations are continuing of the debris plume caused by the collision for as long as possible, as the asteroid system gradually recedes from Earth.

ESA astronaut Samantha Cristoforetti is returning to Earth alongside NASA astronauts Kjell Lindgren, Bob Hines and Jessica Watkins, marking the end of her second mission to the International Space Station, Minerva. Watch Crew-4's return live on ESAwebTV2 from 23:00 CEST (22:00 BST) 12 October.

At Europe’s Spaceport in French Guiana, a test model of the Ariane 6’s central core has been assembled for the first time. Ariane 6 is the first Ariane rocket to be assembled horizontally, which is simpler and less costly than more traditional vertical assembly. One of the P120C boosters can be seen from different angles during installation, before the rocket’s central core is moved to its launchpad and placed upright in its mobile gantry. With the central core and boosters in place, combined tests validate compatibility between all components of the complete launch system.

Certain estimates of Antarctica’s total contribution to sea-level rise may be over, or even underestimated, after researchers detected a previously unknown source of ice loss variability. In a new paper published in The Cryosphere, researchers using Copernicus Sentinel-1 data, found that glaciers feeding the George VI Ice Shelf speed up by approximately 15% during the Antarctic summer. This is the first time that such seasonal cycles have been detected on land ice flowing into ice shelves in Antarctica.

Image: A volcano on the Italian island of Stromboli erupted early on Sunday morning, releasing huge plumes of smoke and a lava flow pouring into the sea. The Copernicus Sentinel-2 mission captured this image of the aftermath less than five hours after the eruption.

The port town of Fos-Sur-Mer, in the southern part of Bouches-du-Rhône, France, is featured in this image captured by Copernicus Sentinel-2. It is from here where the first Meteosat Third Generation Imager satellite set sail last week on its journey to Europe’s Spaceport in French Guiana.

ESA’s flagship Ariane 6 launch vehicle programme has taken a dramatic step towards first flight with the start of a series of hot fire tests of the rocket’s upper stage and its all-new Vinci engine.

Following unusual seismic disturbances in the Baltic Sea, several leaks were discovered last week in the underwater Nord Stream 1 and 2 gas pipelines, near Denmark and Sweden. Neither pipeline was transporting gas at the time of the blasts, but they still contained pressurised methane – the main component of natural gas – which spewed out producing a wide stream of bubbles on the sea surface.

ESA astronaut Samantha Cristoforetti will soon complete her second mission to the International Space Station, Minerva.

Diversity and inclusiveness are at the heart of the ESA’s values and are high on the ESA Agenda 2025 as key elements to complete the ESA Transformation. Eight steps, aimed at advancing these values as concrete initiatives, will pave the way for continuous improvement.

On Friday 30 September, ESRIN, our establishment in Italy, welcomed members of the public on site as part of European Researchers' Night.
Joining research centres throughout Europe, European Researchers' Night, promoted each year by the European Commission, is targeted at people of all ages who want to know more about science, research, and space exploration.

Are you ready to join ESA’s initiative to support European space companies to create a constellation of lunar satellites that connect and guide missions to the Moon?
