So, what provides the necessary energy to accelerate and heat the fastest parts of the solar wind?
Data from our Solar Orbiter and NASA’s Parker Solar Probe have provided conclusive evidence that the answer is large-scale oscillations in the Sun’s magnetic field, known as Alfvén waves.

This video takes you through a rare sky dive. Starting from a vast cosmic panorama bedazzled by some 14 million galaxies, a series of ever-deeper zooms brings you to a crisp view of a swirling spiral galaxy, in a final image enlarged 600 times compared to the full mosaic.
Although the scenes are enticing, they are not taken for their beauty, but to help us advance our understanding of the cosmos. Many of the 14 million galaxies in the initial vista will be used to study the hidden influence of dark matter and dark energy on the Universe.
Unveiled as a teaser of the wide survey, the mosaic accounts for 1% of the area that Euclid will cover over six years, and was obtained by combining 260 observations collected in just two weeks.
This first chunk of Euclid’s survey was revealed on 15 October 2024 at the International Astronautical Congress in Milan, Italy, by ESA’s Director General Josef Aschbacher and Director of Science Carole Mundell.

But this is not new news...
In 2013, our Herschel telescope solved the mystery of water in Jupiter’s upper atmosphere, tracing it back to the impact of comet Shoemaker-Levy 9 in July 1994.
This finding paved the way for our Juice mission, set to reach Jupiter in 2031. Juice’s observations will give us a better chance of understanding how Jupiter’s atmosphere responds to such events.

Hera is ESA’s first planetary defence mission. It will fly to a unique target among the 1.3 million asteroids in our Solar System – the only body to have had its orbit shifted by human action – to solve lingering unknowns associated with its deflection.
Hera will carry out the first detailed survey of a ‘binary’ – or double-body – asteroid, 65803 Didymos, which is orbited by a smaller body, Dimorphos. Hera’s main focus will be Dimorphos, whose orbit around the main body was previously altered by NASA’s kinetic-impacting DART spacecraft.
By sharpening scientific understanding of this ‘kinetic impact’ technique of asteroid deflection, Hera should turn the experiment into a well-understood and repeatable technique for protecting Earth from an asteroid on a collision course.

A shoebox-sized spacecraft from our Hera mission that’s about to explore the binary asteroid system of Didymos and its moon, Dimorphos – a space rock the size of the Great Pyramid!
Using its cutting-edge radar system, Juventas will reveal whether Dimorphos is a solid monolith or simply a loose pile of rubble. Plus, it’s going to gently land and measure the asteroid’s gravity—something never done before!
This tiny spacecraft is set to rewrite what we know about asteroids and could one day help protect our planet.

In this episode, Juice’s Mission Manager Nicolas Altobelli explains how the spacecraft will become the first ever human-made machine to orbit a moon of another planet, in this case Jupiter’s largest moon Ganymede.
You’ll also hear from Claire Vallat and Marc Costa at the European Space Astronomy Centre (ESAC) near Madrid, Spain. Juice will perform incredibly complex measurements once it reaches Jupiter, and the Science Operations team at ESAC is making sure we get the most out of every instrument.
Meanwhile, the Flight Control team at the European Space Operations Centre (ESOC) in Darmstadt, Germany, makes sure Juice is and stays on the right path. This episode shows what happened ‘behind the scenes’ before and during the lunar-Earth flyby, and stars Ignacio Tanco, Angela Dietz and members of the Juice Flight Control team as they do what they do best.
Finally, we highlight the ESA tracking station network (Estrack), another crucial component for Juice. Maintenance and Operations Engineer Belén Goméz gives a tour of the facility at Cebreros.
Following the very successful lunar-Earth flyby, Juice is now on its way to planet Venus for its next flyby. On 31 August 2025, this flyby will give Juice its second gravity boost. Tune back in next year for episode two of this series!
This series follows on from ‘The making of Juice’ series, which covered the planning, testing and launch of this once-in-a-generation mission.

One of the first features Hera will look for is the crater left on Dimorphos by its predecessor mission DART, which impacted the asteroid to deflect its orbit.
Yet, more recent impact simulations suggest no crater will be found. The DART impact is likely to have remodelled the entire body instead – a significant finding for both asteroid science and planetary defence.
📸 ESA - European Space Agency
📹 ESA/NASA
#ESA #HeraMission #Asteroid
On 26 September 2022, moving at 6.1 km/s, NASA’s DART spacecraft crashed into the Dimorphos asteroid. Part of our Solar System changed. The impact shrunk the orbit of the Great Pyramid-sized Dimorphos around its parent asteroid, the mountain-sized Didymos.
This grand experiment was performed to prove we could defend Earth against an incoming asteroid, by striking it with a spacecraft to deflect it. DART succeeded. But that still leaves many things scientists don’t know: What is the precise mass and makeup of Dimorphos? What did the impact do to the asteroid? How big is the crater left by DART’s collision? Or has Dimorphos completely cracked apart, to be held together only by its own weak gravity?
That’s why we’re going back – with ESA’s Hera mission. The spacecraft will revisit Dimorphos to gather vital close-up data about the deflected body, to turn DART’s grand-scale experiment into a well-understood and potentially repeatable planetary defence technique.
The mission will also perform the most detailed exploration yet of a binary asteroid system – although binaries make up 15% of all known asteroids, one has never been surveyed in detail.
Hera will also perform technology demonstration experiments, including the deployment ESA’s first deep space ‘CubeSats’ – shoebox-sized spacecraft to venture closer than the main mission then eventually land – and an ambitious test of 'self-driving' for the main spacecraft, based on vision-based navigation.
By the end of Hera’s observations, Dimorphos will become the best studied asteroid in history – which is vital, because if a body of this size ever struck Earth it could destroy a whole city. The dinosaurs had no defence against asteroids, because they never had a space agency. But – through Hera – we are teaching ourselves what we can do to reduce this hazard and make space safer.

After securing the crucial final assembly and battery connection, we take you inside the thermal vacuum tests (TVAC) to see how YPSat is tested under the extreme temperatures of space; through vibration tests to ensure its structural integrity during launch; and electromagnetic compatibility (EMC) tests to prevent interference with the launcher’s systems.
As we approach the European Space Agency’s traditional Flight Acceptance Review, the satellite is officially certified for flight. With the integration complete and final battery charge applied, control is handed over to the rocket. The only task left for the teams on the ground is to analyse one last time the rocket’s trajectory and await the critical first signal.
As tension builds up on launch day, watch as the team retrieves YPSat’s data and decodes breathtaking images and videos from its mission.

This flyby marked BepiColombo’s closest approach to Mercury yet, and for the first time, the spacecraft had a clear view of Mercury’s south pole.
This timelapse is made up of 128 different images captured by all three of BepiColombo’s monitoring cameras, M-CAM 1, 2 and 3. We see the planet move in and out of the fields of view of M-CAM 2 and 3, before M-CAM 1 sees the planet receding into the distance at the end of the video.
The first few images are taken in the days and weeks before the flyby. Mercury first appears in an image taken at 23:50 CEST (21:50 UTC) on 4 September, at a distance of 191 km. Closest approach was at 23:48 CEST at a distance of 165 km.
The sequence ends around 24 hours later, on 5 September 2024, when BepiColombo was about 243 000 km from Mercury.
During the flyby it was possible to identify various geological features that BepiColombo will study in more detail once in orbit around the planet. Four minutes after closest approach, a large ‘peak ring basin’ called Vivaldi came into view.
This crater was named after the famous Italian composer Antonio Vivaldi (1678–1741). The flyover of Vivaldi crater was the inspiration for using Antonio Vivaldi’s ‘Four Seasons’ as the soundtrack for this timelapse.
Peak ring basins are mysterious craters created by powerful asteroid or comet impacts, so-called because of the inner ring of peaks on an otherwise flattish floor.
A couple of minutes later, another peak ring basin came into view: newly named Stoddart. The name was recently assigned following a request from the M-CAM team, who realised that this crater would be visible in these images and decided it would be worth naming considering its potential interest for scientists in the future.
BepiColombo’s three monitoring cameras provided 1024 x 1024 pixel snapshots. Their main purpose is to monitor the spacecraft’s various booms and antennas, hence why we see parts of the spacecraft in the foreground. The photos that they capture of Mercury during the flybys are a bonus.
The 4 September gravity assist flyby was the fourth at Mercury and the seventh of nine planetary flybys overall. During its eight-year cruise to the smallest and innermost planet of the Solar System, BepiColombo makes one flyby at Earth, two at Venus and six at Mercury, to help steer itself on course for entering orbit around Mercury in 2026.
BepiColombo is an international collaboration between ESA and JAXA.

This episode starts with Rosalind searching for traces of life below the martian surface using a ground penetrating radar and a set of cameras.
The rover will dig, collect, and investigate the chemical composition of material collected by a drill. Rosalind Franklin will be the first rover to reach a depth of up to two metres deep below the surface, acquiring samples that have been protected from surface radiation and extreme temperatures.
Rosalind Franklin uses the WISDOM radar to help scientists on Earth decide where to drill. Besides identifying the most promising targets for sampling, WISDOM will help the rover avoid potential hazards, such as the presence of buried rocks that could damage the drill.
The scientific eyes of the rover are set on the Panoramic Camera suite known as PanCam. The Close-UP Imager (CLUPI) sits on the side of the drill box, a camera designed to acquire high-resolution, colour, close-up images of outcrops, rocks and soils. PanCam and CLUPI will help scientists find the most promising spots to drill. These instruments can also investigate very fine outcrop details and image drill samples before they are sent into the rover’s laboratory.
After the rover retracts its drill, the sample is in a special chamber at the tip. Under the reduced martian gravity (38% of Earth’s), the material drops onto a special “hand” that the rover can extend to the front to collect drill samples.
The mission will serve to demonstrate key technologies that Europe needs to master for future planetary exploration missions.
The ExoMars rover series show the rover and martian landscapes as true to reality as possible for a simulation.

This marks the end of the historic mission, over 24 years after it was sent into space to measure Earth’s magnetic environment. Though the remaining three satellites will also stop making scientific observations, discoveries using existing mission data are expected for years to come.
This ‘targeted reentry’ is the first of its kind. ESA’s efforts to ensure a clean end to the Cluster mission go beyond international standards, making the agency a world-leader in sustainable space exploration.
📹 ESA - European Space Agency
#ESA #Cluster #Satellite
The satellite’s orbit was tweaked back in January to target a region as far as possible from populated regions. This ensures that any spacecraft parts that survive the reentry will fall over open ocean.
During 24 years in space, Cluster has sent back precious data on how the Sun interacts with Earth’s magnetic field, helping us better understand and forecast potentially dangerous space weather.
With this first ever targeted reentry, Cluster goes down in history for a different reason, taking ESA well beyond international space safety standards and helping ensure the long-term sustainability of space activities.

#ESA #Vega #Sentinel-2C
Specialising in launches of small satellites to orbits flying the Earth’s poles, Vega has an impressive roster of missions that it has sent to space. Flagship ESA missions that flew Vega include technology demonstrator and Earth vegetation watcher Proba-V and wind-monitoring satellite Aeolus. Vega’s heaviest payload launched was the 1906-kg LISA Pathfinder, a forerunner to LISA that will measure gravitational waves in space..
In 2015 Vega launched three ESA missions in one year, including reentry demonstrator IXV that showed Europe has the technology to launch a vehicle to space and return it safely to Earth. In less than two hours Vega accelerated IXV to speeds of 27 000 km/h at a height of 412 km before the reentry vehicle splashed down in the Atlantic Ocean. This demonstration mission was a precursor to the reuseable Space Rider spacecraft that will offer regular access to space for research and in orbit validation and demonstration missions and is paired with the Vega family of launchers.
With its Vespa secondary payload adapter, first launched in 2013 on Vega’s second flight, Vega offered different options for payload ride-sharing where multiple satellites are launched on one rocket. In 2020 a variant of Vespa called the Small Spacecraft Mission Service transported over 50 satellites at once to orbit.
Sentinel-2C is the last payload that the Vega rocket launches into space – after 12 years of service. Fittingly the Sentinel-2A and Sentinel-2B satellites were launched on Vega marking a logical conclusion to Vega’s stellar roster of satellites launched.

#ESA #Vega #Rocket
On this last flight, it will carry the Copernicus Sentinel-2C, into orbit. Vega already delivered Sentinel-2A and 2B to space in 2015 and 2017 ensuring constant monitoring of our planet for precision farming, water quality monitoring, natural disaster management and detecting methane emissions.
Since its inaugural flight in 2012, Vega has launched over 20 times, serving Europe with precision and excellence. Now, Vega-C is ready to take the reins, bringing more power and capacity to future missions.

#ESA #Rocket #Satellite
The mission is based on a constellation of two identical satellites: Sentinel-2A and Sentinel-2B. The constellation was originally designed to monitor land surfaces – but its scope has since expanded.
It now covers a wide range of applications including deforestation, water quality, monitoring natural disasters, methane emissions and much more.
Sentinel-2C, once in orbit, will replace the Sentinel-2A unit – prolonging the life of the Sentinel-2 mission – ensuring a continuous supply of data for Copernicus, the Earth observation component of the EU Space Programme.
Tune in to ESA WebTV on 4 September from 03:30 CEST to watch the satellite soar into space on the last Vega rocket to be launched from Europe’s Spaceport in Kourou, French Guiana.

It is nestled between the colossal martian ‘Grand Canyon’ (Valles Marineris) and the tallest volcanoes in the Solar System (the Tharsis region).
The intense volcanism in the nearby Tharsis region is to blame for the formation of these features; this volcanism caused large areas of martian crust to arch upwards and become stretched and tectonically stressed, leading to it thinning out, faulting and subsiding.

The closest approach to the Moon was at 23:15 CEST on 19 August, deflecting Juice towards a closest approach to Earth just over 24 hours later at 23:56 CEST on 20 August. In the hours before and after both close approaches, Juice’s two monitoring cameras captured photos, giving us a unique ‘Juice eye view’ of our home planet.
Juice’s two monitoring cameras provide 1024 x 1024 pixel snapshots that can be processed in colour. Their main purpose is to monitor the spacecraft’s various booms and antennas, especially during the challenging period after launch. The photos they captured of the Moon and Earth during the lunar-Earth flyby are a bonus.
The piece of music that accompanies the images is called 11,2 km/s. It was composed by Gautier Acher back in 2015, and selected as the official theme music for ESA’s Estrack ground station network to mark its 40th anniversary (more information). The music is available under a CC BY-NC-SA licence.

Flight controllers guided the spacecraft past the Moon and then the Earth, ‘braking’ the spacecraft.
This manoeuvre may seem counterintuitive but will allow Juice to take a shortcut via Venus on its way to Jupiter.

The images will be captured using Juice’s two ‘monitoring cameras’, designed to watch the unfolding of Juice’s solar panels, antennas and booms in space in the weeks after the spacecraft launched into space in April 2023. The cameras have successfully completed their task. But we thought… what will we see if we point them at the Moon?
We don’t know how the images will look. It’s the first time the cameras will point at a big bright object in space. And we’re sharing them publicly before we’ve had a chance to process them at all.
Let’s see what happens!

This is annoying for researchers as it limits the time they can study foams and interferes with their experiments. But in space foams are more stable as the liquid does not drain to the bottom in weightlessness.

Enter ESA’s Arctic Weather Satellite: a brand new prototype mission to show exactly how this can be achieved. The satellite will provide precise, short-term weather forecasts for the Arctic region. It is equipped with a 19-channel cross-track scanning microwave radiometer which will provide high-resolution humidity and temperature soundings of the atmosphere in all weather conditions.
The Arctic Weather Satellite is the forerunner of a potential constellation of satellites, called EPS-Sterna, that ESA would build for Eumetsat if this first prototype Arctic Weather Satellite performs well.

The distorted spiral galaxy at the centre, the Penguin, and the compact elliptical galaxy at the left, the Egg, are locked in an active embrace. A new near- and mid-infrared image from the James Webb Space Telescope, taken to mark its second year of science, shows that their interaction is marked by a faint upside-down U-shaped blue glow.
The pair, known jointly as Arp 142, made their first pass between 25 and 75 million years ago — causing ‘fireworks’, or new star formation, in the Penguin. In the most extreme cases, mergers can cause galaxies to form thousands of new stars per year for a few million years. For the Penguin, research has shown that about 100 to 200 stars have formed per year. By comparison, our Milky Way galaxy (which is not interacting with a galaxy of the same size) forms roughly six to seven new stars per year.
Arp 142 lies 326 million light-years from Earth in the constellation Hydra.

Our astronaut Andreas Mogensen was in space, was part of a study to explore how space travel affects the human immune system.
Before, during and after his Huginn mission, Andreas collected both blood and saliva samples to reveal how the body's defences adjust to space.
This research is crucial for developing strategies to manage the health challenges faced by astronauts on long missions.

The culprit? An active sunspot region called AR3664. As it rotated away from Earth’s view around 14 May, it sent out the strongest flare yet (class X8.79), causing large radio blackouts on Earth. But the fact that we could not see it anymore from Earth did not mean that this monster had gone to sleep.
Watching the Sun’s far side on 20 May, Solar Orbiter’s X-ray instrument STIX observed a massive flare with an estimated class of X12. This makes it the strongest flare yet of the current solar cycle, and in the top ten flares since 1996.

The drones have to complete a course as fast as possible, showing how quickly and efficiently they can react, just like a spacecraft would need to in space.
Normally, spacecraft manoeuvres are planned on the ground and then uploaded to the spacecraft to be carried out. But space is full of unpredictable events! Whenever the spacecraft deviates from its planned path for whatever reason, it has to use a lot of fuel and resources to get back on track.
Instead, with this alternative AI control system that’s being tested here, the spacecraft would continuously recalculate and adjusts its path in real-time from wherever it is.
This approach would be much more efficient because the spacecraft could handle unexpected changes better and use fewer resources to stay on course.

At first, the object appeared to orbit Earth in a similar way to our Moon. But astronomers found it was actually orbiting the Sun on a very similar path to Earth. So, Kamo’oalewa was demoted from a potential new moon to a near-Earth asteroid and a quasi-satellite to Earth.
However, the asteroid's connection to the Moon could run deeper. The object's Earth-like orbit and Moon-like composition may indicate that it was created when a chunk of the Moon was thrown into space by an asteroid impact.

The remarkable event was the first direct observation of an extraterrestrial collision in the Solar System.
Huge plumes up to 3 thousand kilometres high were created by the impact and raised the atmospheric temperatures to 40,000 degrees Celsius.
Almost 10 years after the collision, our Herschel telescope found conclusive evidence that Shoemaker-Levy 9 was the origin of water found in Jupiter's upper atmosphere. Our Juice mission launched last year will map the distribution of Jupiter’s atmospheric ingredients in even greater detail.
This kind of collision was more frequent in the early solar system but today, something as large as Shomaker-Levy impacts Earth only once in a million years.
However, it is important we can protect ourselves from such space hazards which is why we are carrying out several projects dedicated to improving our ability to detect, track and mitigate potentially hazardous asteroids and comets, such as our Hera mission currently planned to launch later this year and our new mission, Ramses, which will to rendezvous with the asteroid Apophis.

However, Apophis will still pass closer than some satellites currently orbiting Earth and will be visible with the naked eye.
This rare event is a great opportunity to study Apophis up close and prepare for future asteroid encounters.

Europe’s new rocket Ariane 6 powered Europe into space taking with it a varied selection of experiments, satellites, payload deployers and reentry demonstrations that represent thousands across Europe, from students to industry and experienced space actors.
This inaugural flight, designated VA262, is a demonstration flight to show the capabilities and prowess of Ariane 6 in escaping Earth's gravity and operating in space. Nevertheless, it had several passengers on board.
Ariane 6 was built by prime contractor and design authority ArianeGroup. In addition to the rocket, the liftoff demonstrated the functioning of the launch pad and operations on ground at Europe's Spaceport. The new custom-built dedicated launch zone was built by France's space agency CNES and allows for a faster turnover of Ariane launches.
Ariane 6 is Europe’s newest heavy-lift rocket, designed to provide great power and flexibility at a lower cost than its predecessors. The launcher’s configuration – with an upgraded main stage, a choice of either two or four powerful boosters and a new restartable upper stage – will provide Europe with greater efficiency and possibility as it can launch multiple missions into different orbits on a single flight, while its upper stage will deorbit itself at the end of mission.
ESA’s main roles in the Ariane 6 programme is as contracting authority – managing the budget from Member States participating in the Ariane 6 development programme; and as launch system architect – ensuring that the rocket and launch pad infrastructure work together.
Ariane 6 is the latest in Europe's Ariane rocket series, taking over from Ariane 5 featuring a modular and versatile design that can launch missions from low-Earth orbit and farther out to deep space.
