High above the Arctic Circle, on the rugged terrain of Andøya, three ESA radionavigation engineers take a rare moment to unwind with a game of shuffleboard. Outside, sheep graze under the shimmering northern lights, a serene backdrop to their demanding mission: test how navigation technologies withstand interference signals. With 100TB of data collected over 5 days, their efforts promise to strengthen the reliability of satellite navigation for the benefit of us all. View the full article

Video: 00:03:21 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 …

Video: 00:02:43 On 12 March 2025 ESA’s Hera spacecraft for planetary defence performs a flyby of Mars. The gravity of the red planet shifts the spacecraft’s trajectory towards the Didymos binary asteroid system, shortening its trip by months and saving substantial fuel. This is a simulation of that flyby, sped up 500 times, with closest approach to Martian moon Deimos taking place at 12:07 GMT and Mars occurring at 12:51 GMT. It was made using SPICE (Spacecraft, Planet, Instrument, C-matrix, Events) software. Produced by a team at ESA’s ESAC European Space Astronomy Centre, this SPICE visualisation is used to plan instrument acquisitions during Hera’s flyby. Hera …

Video: 00:01:36 On Wednesday 12 March 2025 ESA’s Hera spacecraft for planetary defence performs a flyby of Mars. The gravity of the red planet shifts the spacecraft’s trajectory towards its final destination of the Didymos binary asteroid system, shortening its trip by months and saving substantial fuel. Watch the livestream release of images from Hera’s flyby by the mission’s science team on Thursday 13 March, starting at 11:50 CET! Hera comes to around 5000 km from the surface of Mars during its flyby. It will also image Deimos, the smaller of Mars’s two moons, from a minimum 1000 km away (while venturing as close as 300 km). Hera will also image Mars’s larger …

Europe’s newest rocket, Ariane 6, took flight for the second time from Europe’s Spaceport in French Guiana at 13:24 local time on 6 March (16:24 GMT, 17:24 CET). This was the first commercial flight for Ariane 6, flight VA263, delivering the CSO-3 satellite to orbit. Arianespace was the operator and launch service provider for the French Procurement agency (DGA) and France’s space agency CNES on behalf of the French Air and Space Force’s Space Command (CDE).
