ESA and the EU agree to accelerate the use of space
ESA will work closely with the EU to use space to improve life on Earth, following an agreement signed today by ESA Director General Josef Aschbacher (left) and the European Commission’s Director-General for Defence Industry and Space, Timo Pesonen.

Hubble goes hunting for small main-belt asteroids
Astronomers recently used a trove of archived images taken by the NASA/ESA Hubble Space Telescope to visually snag a largely unseen population of smaller asteroids in their tracks. The treasure hunt required pursuing 37 000 Hubble images spanning 19 years. The payoff was finding 1701 asteroid trails, with 1031 of those asteroids uncatalogued. About 400 of these uncatalogued asteroids are about below a km in size.
ESA selects four new Earth Explorer mission ideas
As humans exert greater pressure on natural processes, understanding the intricate workings of our Earth system is increasingly vital for effective action on mitigation and adaption strategies. ESA’s Earth Explorer missions yield a wealth of astonishing findings, serving as the bedrock of scientific research in this field. Now, four new concepts have been selected to undergo assessment study, one of which is destined to be the twelfth in this family of world-leading satellite missions.
EarthCARE out of the box
After being packed up in Germany, a long voyage to the US and then a month in storage, ESA’s EarthCARE satellite has been carefully lifted out of its transport container so that the team at the launch site can start getting it ready for its big day in May.
Sleeping giant surprises Gaia scientists
Wading through the wealth of data from ESA’s Gaia mission, scientists have uncovered a ‘sleeping giant’. A large black hole, with a mass of nearly 33 times the mass of the Sun, was hiding in the constellation Aquila, less than 2000 light-years from Earth. This is the first time a black hole of stellar origin this big has been spotted within the Milky Way. So far, black holes of this type have only been observed in very distant galaxies. The discovery challenges our understanding of how massive stars develop and evolve.

The Incredible Adventures of the Hera mission – The Missing Puzzle Piece
Meet Hera, our very own asteroid detective. Together with two CubeSats – Milani the rock decoder and Juventas the radar visionary – Hera is off on an adventure to explore Didymos, a double asteroid system that is typical of the thousands that pose an impact risk to planet Earth.
In September 2022 NASA’s DART spacecraft tested if it was possible to divert an asteroid by giving it a shove – and found out that it was! Important knowledge, should we wish to avoid going the same way as the dinosaurs. Astronomers can observe from afar how the smaller asteroid’s orbit has shifted since DART’s impact, but there is still a missing piece of the puzzle if we want to fully understand how ‘kinetic impacting’ works in practice. Suitable for kids and adults alike, this episode of ‘The Incredible Adventures of Hera’ explains why ESA’s asteroid detective and its CubeSat assistants need to get up close and personal to shine light on this cosmic mystery.

ESA astronaut graduation: launching into the future
One year of basic training will soon bear fruit for ESA’s astronaut candidates Sophie Adenot, Pablo Álvarez Fernández, Rosemary Coogan, Raphaël Liégeois, Marco Sieber and Australian Space Agency astronaut candidate Katherine Bennell-Pegg.
On 22 April 2024, these astronaut candidates will receive their certification at ESA's European Astronaut Centre in Cologne, Germany, officially becoming fully fledged astronauts eligible for spaceflight.

ESA astronaut class of 2022 graduation ceremony
As they reach the end of one year of rigorous basic astronaut training, ESA astronaut candidates Sophie Adenot, Rosemary Coogan, Pablo Álvarez Fernández, Raphaël Liégeois, Marco Sieber and Australian Space Agency astronaut candidate Katherine Bennell-Pegg will receive astronaut certification at ESA’s European Astronaut Centre on 22 April 2024.
The group was selected in November 2022 and began their training in April 2023.
Basic astronaut training provides the candidates with an overall familiarisation and training in various areas, such as spacecraft systems, spacewalking, flight engineering, robotics and life support systems, as well as survival and medical training.
Following certification, the new astronauts will move on to the next phases of pre-assignment and mission-specific training, paving the way for future missions to the International Space Station and beyond.
Join us for the graduation ceremony live on ESA Web TV on Monday 22 April from 10:00 – 11:30 CEST.
Juice’s first year in space: “it’s real now”
One year since the launch of ESA’s Jupiter Icy Moons Explorer (Juice), we catch up with core team members Claire Vallat, Giuseppe Sarri, Olivier Witasse and Ignacio Tanco.
From memories of launch day to hopes for the future, they talk honestly about the ups and downs of flying a space mission, and reveal how they’re ensuring that Juice will be a huge success.
A tour of the International Space Station with Andreas Mogensen
On the last day of his Huginn mission, ESA astronaut Andreas Mogensen takes us on a tour of the place he called home for 6 months: the International Space Station. From the beautiful views of Cupola to the kitchen in Node 1 filled with food and friends and all the way to the science of Columbus, the Space Station is the work and living place for astronauts as they help push science forward.
