ESA opens ideas factory to boost space innovation in Austria
A centre to innovate the design and manufacture of space hardware has today opened in Vienna. Driving commercialisation in space, it is the first of its kind of ESA-backed disruptive innovation centres outside ESA’s own premises.
Hera asteroid mission’s side-trip to Mars
ESA’s Hera asteroid mission for planetary defence will make a swingby of Mars next March, borrowing speed to help reach its target Didymos binary asteroid system.
Dead star lights up nearby galaxy
While ESA's Integral was observing the sky, it suddenly spotted a burst of gamma-rays coming from the nearby galaxy M82. Only a few hours later, ESA’s XMM-Newton searched for an afterglow from the explosion but found none. Astronomers realised that the burst must have been an extra-galactic flare from a magnetar, a young neutron star with an exceptionally strong magnetic field.
Signs of spiders from Mars
No sign of Ziggy Stardust – but ESA’s Mars Express has snapped the telltale traces of ‘spiders’ scattered across the southern polar region of Mars.
From space to soil
Soil sealing might not be a term that everyone's familiar with, but its effects are felt far and wide, particularly in urban areas.
Recognising the urgencies of addressing soil sealing and its associated challenges, an ESA-funded project, Ulysses, is offering insights into the extent and severity of soil sealing to mitigate soil degradation in the Mediterranean region.
Ariane 6 flies OOV-Cube: Internet of (wild) Things
Europe’s newest rocket soon launches, taking with it many space missions each with a unique objective, destination and team at home, cheering them on. Whether launching new satellites to look back and study Earth, peer out to deep space or test important new technologies in orbit, Ariane 6’s first flight will showcase the versatility and flexibility of this impressive, heavy-lift launcher. Read on for all about OOV-Cube, then see who else is flying first.
Hubble celebrates 34th anniversary
In celebration of the 34th anniversary of the launch of the legendary NASA/ESA Hubble Space Telescope on 24 April, astronomers took a snapshot of the Little Dumbbell Nebula (also known as Messier 76, M76, or NGC 650/651) located 3400 light-years away in the northern circumpolar constellation Perseus. The photogenic nebula is a favourite target of amateur astronomers.
Space Team Europe for Ariane 6: Julien Guiridlian
They say it takes a village to raise a child. To launch a rocket, we have the combined expertise and passion of Space Team Europe. Julien Guiridlian is one of many making the first Ariane 6 launch possible and has been interviewed as part of a series highlighting some of the people that make up this dream team.
Working for France’s space agency CNES, Julien is Ariane launch complex assistant, which means he takes care of the ground segment for the combined tests on Europe’s new rocket. Julien takes care of coordinating everything from the fuel for the launcher, to ensuring there is electricity and the mechanical connections between the rocket and the launch pad. Ariane 6 is all about teamwork, and the team is ready for the match.
Stay tuned for more from #SpaceTeamEurope: an ESA space community engagement initiative to gather European space actors under the same umbrella sharing values of leadership, autonomy, and responsibility.
Six mind-blowing facts about Galileo
Did you know Galileo was born in the Netherlands in the 1990s? Europe’s own global navigation satellite system was developed in ESA’s technological heart, ESTEC, in Noordwijk, almost three decades ago. Since then, it has grown to become one of the most complex and critical infrastructures ever built in Europe, as well as the largest European satellite constellation and ground segment.
ESA astronaut class of 2022 graduation ceremony replay
Watch a replay of the ESA astronaut class of 2022 graduation ceremony.
ESA astronaut candidates Sophie Adenot, Rosemary Coogan, Pablo Álvarez Fernández, Raphaël Liégeois, Marco Sieber and Australian Space Agency astronaut candidate Katherine Bennell-Pegg received astronaut certification at ESA’s European Astronaut Centre on 22 April 2024. This officially marks their transition into fully-fledged astronauts, ready and eligible for spaceflight.
The group was selected in November 2022 and began their year-long basic astronaut training in April 2023.
Basic astronaut training provides the candidates with 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.
10 ways Earth is interconnected
On this Earth Day, we reflect on the importance of protecting our planet for future generations. Understanding the Earth system and the complex interactions that shape our planet is paramount for addressing environmental challenges, mitigating climate change, preparing for natural disasters, managing resources sustainably and conserving biodiversity.
Each component of the Earth system – from the atmosphere and oceans to land surfaces and ice sheets – influences and interacts with one another in complex ways. ESA works all-year round to provide satellite data to monitor the health of our planet. Here are 10 examples of how Earth’s systems intertwine and how satellite measurements are key to understanding these complex processes.
