ESA’s Euclid mission is designed to bring the dark side of the Universe to light. Based on the way galaxies rotate and orbit one another, and the way in which the Universe is expanding, astronomers believe that two unseen entities dominate the composition of our cosmos. They call these mysterious components dark matter and dark energy, yet to date we have not been able to detect either of them directly, only inferring their presence from the effects they have on the Universe at large.
To better understand what dark matter and dark energy may be, we need a mission that can more closely reveal what effects they have had on galaxies, galaxy clusters and the expansion of the Universe itself. Euclid is that mission.
ESA’s Euclid mission will create a 3D-map of the Universe, with the third dimension representing time itself. The further away a galaxy is located, the longer its light has taken to reach us and so the earlier in cosmic history we will see it. By observing billions of galaxies out to a distance of 10 billion light-years, scientists will be able to chart the position and velocity of galaxies over immense distances and through most of cosmic history, and trace the way the Universe has expanded during that time. Euclid’s extraordinary optics will also reveal subtle distortions in the appearance of galaxies.
From this wealth of new data, astronomers will be able to infer the properties of dark energy and dark matter more precisely than ever before. This will help theorists pin down the nature of these mysterious components and develop a refined understanding of how gravity behaves at the largest distances.

For a quarter century, Ariane 5 has been Europe’s heavy-lift workhorse. Flying from Europe’s Spaceport in French Guiana, Ariane 5 has carried to space a long series of commercial and scientific missions. Notable payloads include ESA’s comet-chasing Rosetta, a dozen of Europe’s Galileo navigation satellites – orbited with just three launches – the NASA/ESA/CSA James Webb Space Telescope and, in April 2023, ESA’s Juice mission to Jupiter.
Ariane 5 more than doubled the mass-to-orbit capacity of its predecessor, Ariane 4, which flew from 1988 until 2003 as a favourite of the telecommunications industry with its need to put large payloads into very high geosynchronous orbits. Ariane 5’s capacity enabled it to orbit two large telecommunications satellites on a single launch, or to push very large payloads into deep space.
After 117 flights, Ariane 5 is being replaced by an all-new launch vehicle, Ariane 6.

The level of practical expertise, technical and operational expertise required to operate in such a fast-paced, rapidly changing environment such as space needs to be permanently developed and improved to maintain the technical excellence at the right level. But the constant improvement of the technical and operational knowledge is an exciting journey. Nicolas has experienced this first-hand since he joined the European Space Agency Operation Centre as Ground Station Engineer. As a young engineer at ESA, you can gain extremely valuable expertise through launch campaigns, test and validation campaigns, time at the console in the operation control room together with your team, witnessing and learning from the whole life cycle of a real satellite mission, one impossible thing at the time.
With 35 years of experience at ESA, Nicolas Bobrinsky is the former Head of Ground Systems Engineering & Innovation Department. He initiated and further managed the Space Situational Awareness and later the ESA Space Safety Programme.
In four episodes of this new series of ESA Masterclass, Nicolas takes us through major events in his career at ESA, covering cornerstone missions, first attempts, overcoming technical challenges, leading diverse teams and solving the unexpected problems that are part of any space endeavour.

Imagine you are singing in a choir. You are doing your best, just like everybody else. Suddenly, somebody turns to you and points out that you are not singing the right note. If you are told off in a harsh way, you may feel bad about it, and if this happens too often you might not only feel upset about the choir but might even leave it for good. Eventually, the whole choir could end if everybody just leaves.
It is the duty of the choir conductor (the ESA team head) to be able to address every single situation in the right way, to make everyone feel heard and encouraged.
In the third video of this new series of ESA Masterclass, Nicolas shares some lessons learned in his decades as a team leader on what it takes to keep a team together through mutual trust and recognition and make all members work in a harmonious way, like singers of a well-tuned choir.

Satellites in orbit underpin our modern lives. They are used in many areas and disciplines, including space science, Earth observation, meteorology, climate research, telecommunication, navigation and human space exploration. However, as space activities have increased, a new and unexpected hazard has started to emerge: space debris.
If space debris – uncontrolled human-made objects such as spent upper stages of rockets and pieces of satellites – hits a satellite, it could cause serious damage, which can even end a mission (as has happened in the past). If debris crashes on Earth’s surface, it could potentially hit populated areas.
In this second video, Nicolas looks back on the first key steps taken at ESA to develop the Space Safety Programme, devoted to the detection, prevention and mitigation of threats originating from space. This includes not just space debris but also asteroids and space weather. The latter is an intense, occasional energetic storm of particles and material emitted by the Sun. Mitigating these hazards protects our planet, society and economically-important infrastructure on Earth and in orbit.
A key element for the forecasting and prevention of space weather is to observe the Sun from the side. Discover more in this second video of the ESA Masterclass with Nicolas Bobrinsky.

This video takes the viewers on a journey to the barred spiral galaxy NGC 5068, whose bright central bar is visible in the upper left of this image. NGC 5068 lies around 17 million light-years from Earth in the constellation Virgo.
With its ability to peer through the gas and dust enshrouding newborn stars, the NASA/ESA/CSA James Webb Space Telescope is the perfect telescope to explore the processes governing star formation. Stars and planetary systems are born amongst swirling clouds of gas and dust that are opaque to visible-light observatories like Hubble or the VLT. The keen vision at infrared wavelengths of two of Webb’s instruments — MIRI and NIRCam — allowed astronomers to see right through the gargantuan clouds of dust in NGC 5068 and capture the processes of star formation as they happened. This image combines the capabilities of these two instruments, providing a truly unique look at the composition of NGC 5068.

Innovation is triggered by many drivers. One of these is the constant need for ESA to develop innovative solutions,such asuniquespacecrafttechnologies.
In this first video, Nicolas recalls how he and his team had to think outside the box to find a solution for ESA to communicate with Ulysses. Thespacecraft was flyingaround the north pole of the Sun,which ismuch fartherin deep spacethan satellites had beenlaunched up to that point.
The success of this solution motivated the decision to build ESA’sfirst deep-space communications antennas in New Norcia, in Australia, thus enabling many ESA scientific firstsin deep-space exploration.
The antennas would, some decades after, be critically important receivers forthe messages sent by the very distant Rosetta probe, on its quest to find and land on the comet 67P/Churyumov–Gerasimenko, and other ESA science and exploration missions such as Mars Express, Venus Expressand Cassini-Huygens.

Axiom Mission 2 crew members return to Earth, discussing unidentified anomalous phenomena, and a water plume off of Saturn’s moon, Enceladus … a few of the stories to tell you about – This Week at NASA!
Detect, fetch and collect. A seemingly easy task is being tested to find the best strategy to collect samples on the martian surface, some 290 000 million km away from home.
Testing technologies for Mars exploration is part of the daily job of Laura Bielenberg, an ESA graduate trainee for the Mars Sample Return campaign.
The test takes place at the rock-strewn recreation of the Red Planet at ESA’s ESTEC technical centre in Noordwijk, the Netherlands. The nickname of this test site is the ‘Mars Yard’ and is part of the Planetary Robotics Laboratory.
The tube is a replica of the sample caches that NASA’s Perseverance rover is leaving on Mars hermetically sealed with precious martian samples inside. They are called RSTA, an acronym of Returnable Sample Tube Assembly, and to most people on Earth they look like lightsabers. Laura is investigating sample tube collection strategies, from autonomous detection to pose estimation of sample tubes on Mars, with a testbed called the RABBIT (RAS Bread Boarding In-house Testbed).
The Sample Transfer Arm will need to load the tubes from the martian surface for delivery towards Earth. ESA’s robotic arm will collect them from the Perseverance rover, and possibly others dropped by sample recovery helicopters as a backup.
Besides cameras and sensors, the team relies on neural networks to detect the tubes and estimate their pose. Inspired by the way the human brain works, neural networks mimic the way biological neurons signal to one another.

Lying in bed for a full 60 days – with one shoulder always touching the mattress – might sound like bliss, but add cycling, spinning and constant medical tests to the equation and it becomes a challenging experience for the sake of human space exploration.
A group of 12 volunteers are bracing themselves for a bedridden journey that put them into a compulsory reclined lifestyle. Participants are kept in beds tilted 6 degrees below the horizontal with their feet up – meals, showers and toilet breaks included.
As blood flows to the head and muscle is lost from underuse, researchers are charting how their bodies react. Bedrest studies offer a way of testing measures to counter some of the negative aspects of living in space.
During space missions, astronauts’ bodies go through a wide array of changes due to lack of gravity – everything from their eyes to their heart is affected, and muscles and bones start to waste away.

The name of Andreas’s second mission to the Space Station is ‘Huginn’. Inspired by Norse mythology, the name is taken from one of two ravens who serve the god Odin. Called Huginn and Muninn, these two birds sit on Odin’s shoulders and are sent flying across the world at dawn. They return at night to inform him of the many events they have seen and heard. In Old Norse, ‘Huginn’ means ‘thought’ and ‘Muninn’ means ‘mind’ or ‘memory’.
ESA astronaut Andreas Mogensen is going on his first long-duration mission to the International Space Station. Andreas will be the pilot on the SpaceX Crew Dragon that will carry him and the rest of Crew-7 to the Space Station – a first for a European! Representing Europe in space, Andreas will carry out science throughout his mission and bring back the knowledge to Earth, for the benefit of humankind.

The European Space Agency (ESA) is currently training five astronaut candidates for future missions to the International Space Station and beyond. Their training programme consists of three phases: The first phase is basic training, which covers medical exams, fitness assessments, and space programmes and systems. The second phase, the pre-assignment training, is advanced training in specific areas such as systems training, vehicle training, robotics and EVA-training. The third phase is mission-specific training, which is tailored to the tasks and experiments that astronauts will perform during their mission. ESA’s astronaut training programme also includes training for exploration of the lunar surface, as astronauts will need to apply their skills and knowledge to new challenges in future space missions beyond Earth orbit.

The NASA/ESA/CSA James Webb Space Telescope has taken a stunning image of the Solar System’s other ice giant, the planet Uranus. The new image features dramatic rings as well as bright features in the planet’s atmosphere. The new Webb data of Uranus offer exquisite sensitivity, revealing the faintest dusty rings.
The seventh planet from the Sun, Uranus is strange: it rotates on its side, at a nearly 90-degree angle from the plane of its orbit. This causes unusual seasons since the planet’s poles experience 42 years of constant sunlight and 42 years of complete darkness (Uranus takes 84 years to orbit the Sun). Currently, it is late spring at the northern pole, which is on the right side of this image; Uranus’s northern summer will be in 2028.

The main goal of the Jupiter Icy Moons Explorer, Juice, is to characterise Jupiter’s icy moons as both planetary objects and possible habitats. But by observing Jupiter’s atmosphere, magnetosphere, and system of moons and rings, the mission will also reveal how different aspects of the planet’s environment affect one another. In this way, Juice will improve our knowledge of Jupiter as a unique planet and as a whole system.
With Jupiter being like a ‘mini solar system’, we will be able to apply this knowledge to our own Solar System and other planetary systems in the Universe, improving our understanding of how gas giants form and behave, and the potential for life to exist on their orbiting worlds. This knowledge will feed into our exoplanet monitoring programme, which currently consists of a trifecta of dedicated missions – Cheops, Plato and Ariel – complemented by Webb.

Chariklo is an icy, small body, but the largest of the known Centaur population, located more than 3.2 billion kilometres away beyond the orbit of Saturn. Chariklo is only 250 kilometers or ~51 times smaller than Earth in diameter, and its rings orbit at a distance of about 400 kilometers from the center of the body.
On 18 October 2022, a team used the James Webb Space Telescipe to closely monitor the star Gaia DR3 6873519665992128512, and watch for the tell-tale dips in brightness indicating an occultation had taken place. The shadows produced by Chariklo’s rings were clearly detected, demonstrating a new way of using Webb to explore solar system objects. The star shadow due to Chariklo itself tracked just out of Webb’s view. This appulse (the technical name for a close pass with no occultation) was exactly as had been predicted after the last Webb course trajectory maneuver.

When a spacecraft launches on a mission to another planet it must first break free of the Earth’s gravitational field. Once it has done that, it enters interplanetary space, where the dominant force is the gravitational field of the Sun.
The spacecraft begins to follow a curving orbit, around the Sun, which is similar to the orbit of a comet. When this orbit brings it close to its target destination the spacecraft must fire a retrorocket to slow down and allow itself to be captured by the gravitational field of its target. The smaller the target, the more the spacecraft must slow down.
Sometimes passing a planet can result in the spacecraft being accelerated, even without the spacecraft firing any of its thrusters. This is known as the ‘slingshot’ effect. Such ‘gravity assist’ manoeuvres are now a standard part of spaceflight and are used by almost all our interplanetary missions. They take advantage of the fact that the gravitational attraction of the planets can be used to change the trajectory and speed of a spacecraft.
The amount by which the spacecraft speeds up or slows down is determined by whether it is passing behind or in front of the planet as the planet follows its orbit. When the spacecraft leaves the influence of the planet, it follows an orbit on a different course than before.

Our Jupiter Icy Moons Explorer, Juice, will make detailed observations of the giant gas planet and its three large ocean-bearing moons – Ganymede, Callisto and Europa – with a suite of remote sensing, geophysical and in situ instruments. The mission will characterise these moons as both planetary objects and possible habitats, explore Jupiter’s complex environment in depth, and study the wider Jupiter system as an archetype for gas giants across the Universe.
Juliet will be taking us to Jupiter and its moons in the coming weeks. So stay tuned for more!

The Drag Augmentation Deorbiting System Nano – a 3.6-sq-m aluminium-coated polyamide membrane attached to four metallic booms – deployed from a 10 cm box aboard a satellite platform launched in 2021 used to deliver miniature ‘CubeSats’ into their individual orbits.
By increasing the overall area of the satellite, the sail will increase the gradual air drag acting upon it from atoms at the top of the atmosphere, and speed up its atmospheric reentry.

Asteroids, like stars, only come out at night. Hidden in the glare of our Sun are an unknown number of asteroids on paths we cannot track, many of which could be heading for Earth, and we just don’t know it.
Our planned NEOMIR mission will be located between Earth and the Sun and will act as an early warning system for asteroids 20 metres and larger that cannot be seen from the ground.
By making observations in the infrared part of the light spectrum, NEOMIR will detect the heat emitted by asteroids themselves, which isn’t drowned out by sunlight. This thermal emission is absorbed by Earth’s atmosphere, but from space NEOMIR will be able to see closer to the Sun than we can currently from Earth.
