ESA’s Hera asteroid mission for planetary defence is about to gain its sight. Two complete and fully tested Asteroid Framing Cameras have reached OHB in Germany for integration aboard Hera’s payload module. This instrument will provide the very first star-like view of Hera’s target for the mission to steer towards the Dimorphos asteroid, which last year had its orbit altered by an impact with NASA’s DART mission.

Video: 00:08:47 In the 1980s, scientists discovered a gaping hole in Earth's ozone layer, caused by humanmade chemicals. But thanks to the historical Montreal Protocol, the world came together to take bold action to save our planet. Decades later, we can see the steady recovery of the ozone hole. How did we do it? And what does space have to do with it? Join us as we explore the journey of the ozone hole, from its alarming discovery to the incredible strides made to fix it, and how satellites are helping us track its recovery. View the full article

This year started with a nice imaging opportunity for Solar Orbiter, and a chance to further improve the quality of its data. On 3 January 2023, inner planet Mercury crossed the spacecraft’s field of view, resulting in a transit where Mercury appeared as a perfectly black circle moving across the face of the Sun.

Understanding Earth’s delicate natural balance and how it is being altered by human activity is not only key to advancing science but also fundamental to acting on environmental issues, the climate crisis, and preparing for their societal impact. With their hallmark of demonstrating novel space technologies and returning scientific excellence, ESA’s family of Earth observing Earth Explorer research satellite missions are world-renowned – and now it’s time for scientists to pitch their new ideas for the twelfth mission in this outstanding series.

Image: ESA’s Euclid mission is undergoing the final test before launch in July 2023. Here it is standing in a special room in the Thales Alenia Space test facilities in Cannes, France, where it successfully underwent electromagnetic compatibility testing. This kind of testing is routine for spacecraft. All electronics emit some form of electromagnetic waves that can cause interference with other devices. Think of the buzz that speakers give out right before an incoming call on a mobile phone. Spacecraft electronics can cause similar interference, but out in space such interference can have disastrous consequences, so all systems must be checked before launch. The large…

Video: 00:04:54 After many years of study, development, building and testing, ESA’s Jupiter Icy Moons Explorer, Juice, has finally arrived at Europe’s Spaceport in Kourou, French Guiana. At the end of 2022 the spacecraft underwent its final thermal vacuum test at an Airbus Defence and Space facility in Toulouse, as well as its final software verification tests, whereby it was controlled from the ESOC mission control centre in Darmstadt, Germany. Soon, an Ariane 5 will lift Juice into orbit and send it on its journey to explore the largest planet in our Solar System and its three icy moons, Europa, Callisto and in particular Ganymede. By exploring and studying the …

Image: No one saw the Chelyabinsk meteor of 15 February 2013 coming – the largest asteroid to strike Earth in over a century. Just after sunrise on a sunny winter’s day, a 20-metre, 13 000 tonne asteroid struck the atmosphere over the Ural Mountains in Russia at a speed of more than 18 km/s. The relatively small rock exploded in the atmosphere at an altitude of 30 km, releasing about half a megaton of energy (equivalent to 35 Hiroshima-sized bombs). Two minutes later, the shockwave reached the ground damaging thousands of buildings, breaking windows and injuring roughly 1500 people from flying shards of glass. Hidden in the glare of our Sun are an unknown number of ast…

Image: For the seventh time, a small asteroid – a meteoroid as astronomers call it – was discovered in space as it raced towards Earth for impact. The predicted time and location of the impact (02:50 - 03:03 UTC, above northern France) were made possible with observations by European astronomer Krisztián Sárneczky using the 60 cm Schmidt telescope from the Piszkéstető Observatory in Hungary. 2023 CX1 is the second impactor discovered by Krisztián, after the impact of 2022 EB5 less than a year ago. The last three predicted impacts have all occurred in the last 12 months– an encouraging illustration of how asteroid detection capabilities are rapidly advancing. What ha…

Video: 00:01:00 ESA's Euclid mission is designed to explore the composition and evolution of the dark Universe. The space telescope will create a great map of the large-scale structure of the Universe across space and time by observing billions of galaxies out to 10 billion light-years, across more than a third of the sky. Euclid will explore how the Universe has expanded and how structure has formed over cosmic history, revealing more about the role of gravity and the nature of dark energy and dark matter. Euclid is a fully European mission, built and operated by ESA, with contributions from NASA. The Euclid Consortium – consisting of more than 2000 scientists fr…

Türkiye and Syria are reeling from one of the worst earthquakes to strike the region in almost a century. Tens of thousands of people have been killed with many more injured in this tragedy. Satellite data are being used to help emergency aid organisations, while scientists have begun to analyse ground movement – aiding risk assessments that authorities will use as they plan recovery and reconstruction, as well as long-term research to better model such events.

ESA’s mission to explore Jupiter and its largest moons has safely arrived at Europe’s Spaceport in French Guiana, where final preparations for its April launch are now underway. The Jupiter Icy Moons Explorer – better known as Juice – arrived on 8 February at Félix Eboué airport in Cayenne by a special Antonov Airlines An-124 cargo flight from Toulouse, France, where prime contractor Airbus completed a nearly decade-long process of concept, design, testing and construction. Now, the spacecraft will undergo final testing and inspection by engineers from ESA and Airbus before it is fueled up and mounted on its Ariane 5 rocket. View the full article
