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

In 2023, ESA published more than 400 vacancies in engineering, science and business and administration and more positions continue to be published as we are always on the lookout for talented new colleagues to join us. So, what does it mean to join ESA? Here are five reasons why you should consider ESA as the next step in your career! 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 altered by NASA’s kinetic-impacting DART spacecraft. By sharpening scientific understanding of this ‘kinetic impact’ technique of asteroid deflection, Hera should turn the experiment into a well-understood and repeatable technique for protecting Earth from an asteroid on a collision course.

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

Thanks to an ESA-funded project and data from the Copernicus Sentinel-2 mission, researchers have revealed seasonal variations in intertidal seagrass across Western Europe and North Africa. As a key indicator of biodiversity, these new findings offer valuable insights for the conservation and restoration of these vital ecosystems. View the full article

As BepiColombo sped past Mercury during its June 2023 flyby, it encountered a variety of features in the tiny planet’s magnetic field. These measurements provide a tantalising taste of the mysteries that the mission is set to investigate when it arrives in orbit around the Solar System’s innermost planet. View the full article

To achieve truly global connectivity, telecommunications satellites are essential.
