Surpassing scientific expectations and exceeding its planned life in orbit, the Aeolus wind mission has been hailed as one of ESA’s most successful Earth observation missions. And now, its end will go down in history too, thanks to the ingenuity of the Agency’s mission control team who guided this remarkable satellite down to Earth’s atmosphere for a safe reentry.

After a remarkable life in orbit, Aeolus is out of fuel and out of time – it’s returning to Earth this week. Planned and built before any regulations were put in place on ‘end-of-life’ disposal, the Earth Explorer was designed to naturally return through our atmosphere.
After months of detailed planning and analysis, ESA together with industrial partners has designed a complex and never-before-performed set of manoeuvres to control, as much as possible, Aeolus’ fall.
The assisted reentry attempt is built on four main phases, now begun at ESA’s mission control:
In this animation, round regions temporarily lit up in bright green show the moments that Aeolus is in contact with antennas on Earth. It is in these periods that mission control is in touch with the satellite and can send up commands and get its data down.
Aeolus is repeatedly turned, or ‘slewed’ by 180° in order to switch from the routine orientation (or ‘attitude’), in which the satellite’s ‘X-band’ antenna points toward Earth and the GPS can function to track the mission – crucial to maintaining knowledge of its position – and the ‘retrograde’ attitude.
This second, ‘upside down’ position is necessary for the thrusters to fire in the opposite direction to Aeolus’s flight direction, causing it to lose energy and lower in orbit.
While the ultimate goal is for the spacecraft to burn up as it reenters through the atmosphere, teams need to keep it functioning long enough that they can continue to send up commands and control it on its path.
After the final commands are sent, Aeolus will be ‘passivated’. Passivation is when any energy onboard a spacecraft is removed, for example, its propellant or batteries. Doing this prevents explosions and fragmentation events, that could cause the release of lots of pieces of unwanted space debris.
For Aeolus, already out of fuel, it will simply be turned off. After this point, teams at mission control will continue to monitor the situation until Aeolus’s ultimate reentry location is confirmed.

To unleash its full potential for decarbonising European transport, the rail sector must operate more efficiently and integrate the latest technologies to advance the digitalisation of the rail system, thereby providing high-quality customer services. ERTMS provides the European Union with a unique opportunity to create a safer, more resilient and interoperable railway network.
Among others, ERTMS aims to make rail transport more competitive by replacing Europe’s different national train control and command systems with a single, coordinated and highly digital solution. To do this, ERTMS aims to rely on data and services from the European Space Programme, namely, the European satellite navigation systems.
Further, according to EUSPA, more than 150,000 freight wagons in Europe are equipped with Galileo/EGNOS receivers to provide more accurate information about the wagon position. Precise location is used for asset and fleet management purposes, becoming a crucial element for efficient supply chain operations and services to customers.
Not only does Galileo provide precise positioning and localisation, but when augmented by EGNOS and other data sources, it has the potential to replace the expensive physical balises used to monitor train speed and streamline rail operations.

Galileo and EGNOS potential become even greater when its positioning is complemented by Earth Observation. For example, railway operators can use the Copernicus Land Monitoring Services and Sentinel-1 data in particular to measure displacements, including landslides and ground subsidence to prevent rail damage or other risks that could endanger the safe operation of trains.
EUSPA, ERA , EU-Rail and the European Commission are joining forces and invite you to the second edition ‘Space for Innovation in Rail – Towards Satellite Based ERTMS’.
The two-day event will gather Europe’s major transport stakeholders, including key decision makers and railway sector representatives across the entire value chain to debate the introduction of the European Union’s Space Programme assets in the rail sector. The main focus of the event will be on the utilisation of the European Global Navigation Satellite Systems (GNSS) for fail-safe train localisation within the European Rail Traffic Management System (ERTMS) evolution.
On the 14th of September, after the official conference programme, the participants will have an opportunity to take part in four unique site visits. Space is limited and will be assigned on a first come, first served basis, so make sure to express your interest in the registration form available below.
"I believe this event will be the best opportunity to reflect on how the EU Space Programme can support railway sector to become digital, taking advantage of the EU Space assets and services to further improve its operational efficiency and reduce the cost of the signalling infrastructure" says EUSPA Executive Director, Rodrigo da Costa.

Globally, more than 70% of the freshwater withdrawn from Earth’s surface or from underground is used to irrigate crops. The need to produce more food for a growing population against the backdrop of climate change is challenging enough, but satellites reveal that extracting water doesn’t just affect the local environment – there are knock-on consequences for many aspects of the Earth system.

ESA’s wind mission Aeolus is coming home. After five years of improving weather forecasts, the satellite will return in a first-of-its-kind assisted reentry. At ESA’s Space Operations Centre in Germany, mission control will use the satellite’s remaining fuel to steer Aeolus during its return to Earth.
Find out more about the mission, its successes and how Aeolus is paving the way for safe reentries.
Interconnected drones have been dispatched into volcanic territory to test their use for civil protection, to help guide responses to natural disasters using novel PNT technology. The project, named Pathfinder, is supported through ESA’s Navigation Innovation and Support Programme, NAVISP. Two test campaigns have been undertaken to date, around the active Stromboli Island volcano and within the Astroni Nature Reserve, in a volcanic crater near Naples.
The recent severe droughts and extremely high temperatures in Hungary, led rivers and lakes to dry up, negatively impacting the country’s economy and ecosystem. With that in mind, EUSPA, together with the Ministry of Foreign Affairs and Trade of Hungary and Eurisy, co-organised a workshop on Satellite-based Services for Disaster Risk Management. Held in Budapest, the workshop brought together national and regional stakeholders to discuss how satellite-based services can support both disaster risk management and search and rescue operations.
Dr. Orsolya Ferencz, Ministerial Commissioner for Space Research at the Ministry of Foreign Affairs and Trade, presented an overview of Hungary's space strategy and outlined its implementation milestones. Speaking about the workshop, Dr Ferencz stated, "This gathering is important in addressing the challenges we face in emergency situations. By leveraging innovative tools and satellite technologies, we can make evidence-based decisions and better respond to disasters."
Copernicus, the EU Earth Observation programme provides up to date, near real-time optical information about disasters such as wildfires and floods.
More precisely, the Copernicus Emergency Management Service (Copernicus EMS) uses data from a range of satellites and ground-based sensors to provide information about the location, extent, and behaviour of fires and floods. This information helps emergency responders make informed decisions regarding where to direct resources and in the case of fires, how to contain the blaze. The service is provided free of charge to all users.
But there’s more. Wildfires are a significant source of air pollution which poses a threat to human, animal, and plant populations.
When a disaster such as a wildfire strikes a region, it is important to have access to precise and up-to-date information for the delivery of an effective disaster management response. The Copernicus Atmosphere Monitoring Service (CAMS) can monitor emissions which can, in turn, be used in smoke forecasts. These forecasts are used in air quality apps to help people limit their exposure to pollution, and by policymakers and local authorities to manage the impact of fires.

Galileo, the EU global navigation satellite system and EGNOS the EU’s regional navigation system have revolutionised various sectors of the European economy such as agriculture and transportation. But their contribution goes even further by helping to save lives.
Take for example the European 112-emergency number. As of March 2022, it became mandatory for all mobile phones sold in the European Single Market to be Galileo enabled. When someone places an emergency call, the emergency responder will receive their location information with an accuracy down to just a few metres. The improved accuracy has a major impact in terms of response times, ultimately allowing for quicker intervention in emergency situations where every second counts – resulting in more lives being saved. The ability for 112 to communicate a caller’s location automatically to emergency services is possible thanks Advanced Mobile Location (AML) system which is already available in Hungary.
Likewise, in case medical assistance is needed, helicopter operators and pilots can rely on EGNOS to land safely, especially when visibility is reduced due to fire smoke or fog. Additionally, services like the Galileo High Accuracy and OSNMA services ensure that drones deliver accurate mapping as well as assistance to inaccessible areas due to natural disasters such as earthquakes.
Equipped with a wide-range of sensors for capturing Earth Observation data and navigated using GNSS positioning, advanced drones can now provide firefighters with another layer of information – and protection.
GOVSATCOM and IRIS2 will provide robustly protected communication, filling the gap for secure communication alongside Galileo and Copernicus. These solutions enable secure and cost-efficient communication for critical missions, operations, and infrastructure. EUSPA, in collaboration with Member States and other entities, oversees the procurement, operations, and user coordination of the secure ground segment (GOVSATCOM Hubs).
Rodrigo da Costa, Executive Director of EUSPA, provided the European perspective on the integrative use of components from the European Space Programme. “Galileo, EGNOS, Copernicus, are powerful tools individually, but an exponential achievement is reached when used in synergy. Soon, the addition of GOVSATCOM and IRIS² will add an extra layer of efficiency in the management of disasters by providing secured and uninterrupted satellite communications to EU Member States. The Emergency Management and Disaster Response sector is one of the key sectors where this synergy is saving lives”. "As an agency focused on meeting user needs, EUSPA closely monitors this market and actively develops and delivers new space-enabled services to address its requirements" he stated.

After completing its mission in orbit, ESA’s wind mission Aeolus will soon reenter Earth's atmosphere. Currently orbiting 320 km above, Aeolus is being kept in orbit with its remaining fuel. This fuel is running out, and the satellite will soon succumb to Earth’s atmosphere and gravity.
Going above and beyond what the satellite was technically designed to do, ESA is attempting a first-of-its-kind assisted reentry to reduce the (already very small) risk of damage from any fragments that survive the journey and reach the ground.
ESA held an online media briefing on 19 July 2023 to explain more about this assisted approach and answer questions.
