Press Release N° 7–2023 On Tuesday 20 December 2022, Arianespace announced the loss of the Vega-C VV22 mission after its launch at 22h47 local time in French Guiana (2h47 CET/1h47 GMT on 21 December 2022). The mission was carrying two payloads, Pléiades Neo 5 and 6 Earth observation satellites for Airbus Defence and Space. View the full article

The NASA/ESA Hubble Space Telescope captured a series of photos of rapid changes to the asteroid Dimorphos when it was deliberately hit by a 545-kilogram spacecraft on 26 September 2022. The primary objective of the NASA mission, called DART (Double Asteroid Redirection Test), was to test our ability to alter the asteroid’s trajectory as it orbits its larger companion asteroid, Didymos. Though Dimorphos poses no threat to Earth, data from the mission could help inform researchers how to potentially change an asteroid’s path away from Earth, if ever necessary. View the full article

Image: This observation from the NASA/ESA/CSA James Webb Space Telescope features the massive galaxy cluster RX J2129. Due to Gravitational lensing, this observation contains three different images of the same supernova-hosting galaxy, which you can see in closer detail here. Gravitational lensing occurs when a massive celestial body causes a sufficient curvature of spacetime to bend the path of light travelling past or through it, almost like a vast lens. In this case, the lens is the galaxy cluster RX J2129, located around 3.2 billion light-years from Earth in the constellation Aquarius. Gravitational lensing can cause background objects to appear strangely distorted…

Like many places, the Antarctic Peninsula is falling victim to rising temperatures. However, when scientists used radar images from the Copernicus Sentinel-1 mission acquired between 2014 and 2021, they were taken aback to discover just how the fast 105 glaciers on the west coast are flowing in the summer months.

A new era of lunar exploration is on the rise, with dozens of Moon missions planned for the coming decade. Europe is in the forefront here, contributing to building the Gateway lunar station and the Orion spacecraft – set to return humans to our natural satellite – as well as developing its large logistic lunar lander, known as Argonaut. As dozens of missions will be operating on and around the Moon and needing to communicate together and fix their positions independently from Earth, this new era will require its own time.

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…
