The day began with an 85% chance that bad weather would cause a launch delay: it ended with ESA’s Hera mission successfully in space and en route to the Didymos binary asteroid system. At 16:52 CEST (14:52 UTC) on 7 October 2024, Hera took to the skies aboard a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida, USA. After a smooth 76-minute ascent, the spacecraft separated from its launcher, and, a few minutes later, ESA’s ESOC mission operations centre in Germany assumed control of the spacecraft. Here is what has happened since then. View the full article

ESA engineers have focused microscopes, hardness testers and an X-ray computer aided tomography machine onto a special aluminium weld just a single centimetre across – the historic result of the very first autonomous welding to be performed in space, and the first ESA has been involved with.

Video: 00:01:20 Approximately 41 000 years ago, Earth’s magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth’s magnetic field weakened significantly—dropping to a minimum of 5% of its current strength—which allowed more cosmic rays to reach Earth’s atmosphere. Scientists at the Technical University of Denmark and the German Research Centre for Geosciences used data from ESA’s Swarm mission, along with other sources, to create a sounded visualisation of the Laschamp event. They mapped the movement of Earth’s magnetic field lines during the event and created a stereo sound version which is what you can hear in the video…

With all instruments integrated, the first MetOp Second Generation-A, MetOp-SG-A1, weather satellite is now fully assembled and on schedule for liftoff next year. Meanwhile, its sibling, MetOp-SG-B1, is undergoing rigorous testing to ensure that it will withstand the vacuum and extreme temperature swings of space. View the full article

ESA’s Mars Express has captured an astonishing array of landforms emerging from a thick winter blanket of frost as spring arrives in the south polar region of Mars. Some of these features are surprisingly dark compared with their icy surroundings, earning their nickname of ‘cryptic terrain’. View the full article

The Sentinel-1C satellite, the third satellite of the Copernicus Sentinel-1 mission, has arrived at the European spaceport in French Guiana for liftoff on the Vega-C rocket at the end of 2024. The satellite will continue the critical task of delivering key radar imagery of Earth’s surface for a wide range of Copernicus services and scientific applications. View the full article

Video: 00:04:05 ESA’s Hera mission lifted off on a SpaceX Falcon 9 from Cape Canaveral Space Force Station in Florida, USA, on 7 October at 10:52 local time (16:52 CEST, 14:52 UTC). Hera is ESA’s first planetary defence mission. It will fly to a unique target among the 1.3 million asteroids in our Solar System – the only body to have had its orbit shifted by human action – to solve lingering unknowns associated with its deflection. Hera will carry out the first detailed survey of a ‘binary’ – or double-body – asteroid, 65803 Didymos, which is orbited by a smaller body, Dimorphos. Hera’s main focus will be Dimorphos, whose orbit around the main body was previously …

Video: 00:11:35 Hera, ESA’s first planetary defence mission, is headed to space. Hera will fly to a unique target among the 1.3 million known asteroids of our Solar System – the first body to have had its orbit shifted by human action – to probe lingering unknowns related to its deflection. Hera is scheduled for launch on a SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station in Florida, USA, today, Monday 7 October, at 16:52 CEST / 15:52 BST. View the full article
