The Copernicus Sentinel Expansion Missions are a major leap forward in Europe’s Earth observation capabilities. With the United Kingdom’s re-entry to the EU’s Copernicus programme, funding has been confirmed to complete the development of all six Copernicus Sentinel Expansion Missions, as discussed this week during the International Astronautical Congress taking place in Milan, Italy.
At the International Astronautical Congress (IAC) in Milan this week, ESA signed a contract for Element #1, the first phase of the HydRON Demonstration System. HydRON, which stands for High thRoughput Optical Network, is set to transform the way data-collecting satellites communicate, using laser technology that will allow satellites to connect with each other and ground networks much faster.
With the initial images from each of the instruments aboard ESA’s EarthCARE satellite now in hand, it's time to reveal how these four advanced sensors work in synergy to measure exactly how clouds and aerosols influence the heating and cooling of our atmosphere.
On 15 October 2024, ESA’s Euclid space mission reveals the first piece of its great map of the Universe, showing millions of stars and galaxies.
This week, at the International Aeronautics Congress in Milan, ESA officially kicked off a new project called Ciseres, a small satellite mission designed to significantly improve crisis response times using artificial intelligence (AI). Part of ESA's Civil Security from Space (CSS) programme, Ciseres aims to enhance satellite capabilities to alert first responders and government officials within minutes of the occurrence of a disaster – such as floods, fires, landslides. The project is led and co-financed by Deimos, a European space tech company specialising in small satellite missions.
Imagine a near future where services such as satellite navigation, video conferencing, and file sharing are as seamless on the Moon as they are on Earth.
ESA has awarded a contract valued at over €280 million to OHB in Germany to build ESA’s two Harmony Earth Explorer satellites.

From 7 until 13 October 2024, ESA/NASA’s SOHO spacecraft recorded Comet C/2023 A3 (Tsuchinshan–ATLAS), the second brightest comet it has ever seen. Meanwhile, large amounts of material were being spewed out by the Sun (covered in the centre), and planet Mercury is visible to the left.
In an era where natural disasters and emergencies are becoming increasingly frequent and severe, ESA is taking a significant step forward in enhancing Europe's crisis management capabilities.
ESA has taken another important step on the road towards sustainability in space with its first in-orbit servicing mission RISE. A €119 million contract was signed with D-Orbit as the co-funding prime contractor.
ESA’s Hera mission for planetary defence has taken its first images using three of the instruments that will be used to explore and study the asteroids Dimorphos and Didymos.

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.
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.

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.
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.
