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 ..read more

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.  ..read more

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 ..read more

Video: 00:02:35 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 shifte ..read more

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 ..read more

Video: 00:01:00 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, fli ..read more

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 ..read more
