In recent weeks, devastating wildfires have spread in Greece, Italy, Spain, Portugal, Algeria, Tunisia and Canada, causing human casualties as well as massive environmental and economic damage.
While wildfires are a natural part of many ecosystems, scientists have warned that they are becoming more frequent and more widespread. In response, an upgraded version of ESA’s World Fire Atlas is now available providing a detailed analysis of wildfires across the globe.
Aeolus’s mission is over, but weather forecasting is improved forever, and a new precedent has been set for safe satellite reentries. The trailblazing Earth Explorer returned through our atmosphere on 28 July, following the path it was guided on by ESA’s mission control over Earth’s most uninhabited regions, finally disintegrating over the Antarctic.
A week-long series of manoeuvres led to this point. They had never been performed before and pushed the satellite to its limits. Aeolus was never designed to fly at such low altitudes – its thrusters and fuel reserves were not made to operate in the thick lower reaches of Earth’s atmosphere.
Despite choppy skies and one evening where it seemed the attempt could fail, the successful reentry lowered the already small risk of surviving fragments landing where they shouldn’t.
The chance of satellite debris falling on your head is three times less than a meteorite doing the same. Despite this, as our orbital highways get busier and reentries become more common, ESA went above and beyond to lower this even further.
By turning Aeolus’s original fate – an uncontrolled, ‘natural’ reentry – into an assisted one, they reduced that risk another 42 times.
This animation shows how the final moments for Aeolus could have gone, set to a sonification of Aeolus data, composed by Jamie Perera.
Find out more about Aeolus’s final moments in the Rocket Science blog.
This simulation is created using a model of the Aeolus spacecraft, considering its shape, size, mass and materials, and the effect of 'aerothermodynamics' - the study of how high-velocity gases behave, including thermal effects between gases and solid surfaces.
The tool used, SCARAB, creates a simulation of Aeolus's reentry with ‘six degrees of freedom’, and shows the final moments of Aeolus's reentry, when the spacecraft is falling naturally in an uncontrolled descent.

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.

Historic Aeolus reentry – how it happened
Get rolling updates on the Aeolus reentry, on the Rocket Science blog
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.

On 10 July 2023, a volcano some 30 km from Iceland’s capital, Reykjavik, erupted following heightened seismic activity in the area. Satellites orbiting above us have captured the molten lava and smoke plume puffing from the Litli-Hrútur volcano.
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.
The Italian region of Emilia-Romagna was devastated by severe floods in May 2023, claiming lives and displacing thousands of people, resulting in an estimated €8.8 billion in damages. With the region still grappling with the aftermath, satellites have been instrumental in assessing the damages of the affected areas.
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.

Fuelled largely by climate change, our planet is being subjected to environmental changes that are having an unprecedented global impact on humans, animals and plants. Shockingly, in certain locations these changes are occurring at a rate never before witnessed.
To keep pace with the challenges we face, ESA is embarking on a new Earth observation science strategy – and has reached out to the scientific community at this early stage in the process to help guide the Agency’s scientific agenda for the coming years.
After almost five years, ESA’s Aeolus wind satellite has completed its mission. Now, you can listen to the Life of Aeolus – an incredible wind orchestral piece that has been composed using data spanning Aeolus’ entire life in orbit around Earth.
Temperatures are sizzling across Europe this week amid an intense and prolonged period of heat. And it’s only just begun. Italy, Spain, France, Germany and Poland are all facing a major heatwave with air temperatures expected to climb to 48°C on the islands of Sicily and Sardinia – potentially the hottest temperatures ever recorded in Europe.

Discover the first results from Europe’s first Lightning Imager onboard the Meteosat Third Generation. The Lightning Imager can continuously detect rapid flashes of lighting in Earth’s atmosphere whether day or night from a distance of 36 000 km.
This is the first time a geostationary weather satellite has the capability to detect lightning across Europe, Africa and the surrounding waters. Each camera can capture up to 1000 images per second and will continuously observe lightning activity from space. The data will give weather forecasters greater confidence in their predictions of severe storms.
The first ever satellite instrument capable of continuously detecting lightning across Europe and Africa has now been switched on. New animations from the innovative ‘Lighting Imager’ confirm the instrument will revolutionise the detection and prediction of severe storms.

ESA has strengthened their partnership with the UN International Fund for Agricultural Development (IFAD) to help vulnerable small-scale food producers not only increase their ability to grow food but adapt to climate change by using state-of-the-art Earth observation data.
By using concrete examples of the water and carbon cycles, the speakers in this session focus on the grand science questions and how we can turn them into answers and solutions most useful to decision-makers at the front line of the climate crisis. Earth is a highly dynamic system where the transport and exchanges of energy and matter are influenced by a multitude of processes and feedback mechanisms. Untangling these complex processes to better understand how Earth works as a system is a major challenge; a challenge that satellites, with their global view, are ideally positioned to tackle. While each mission gives us unique insights, it is by combining their data that makes scientific findings shine the brightest. This, in turn, puts European and international collaboration at the heart of Earth observation today.

The Arctic, once again at the forefront of climate change, is experiencing disproportionately higher temperature increases compared to the rest of the planet, triggering a series of cascading effects known as Arctic amplification. As concerns continue to grow, satellites developed by ESA have become indispensable tools in understanding and addressing the complex dynamics at play and the far-reaching consequences for the environment and human societies.

ESA has been presented the ‘Space for Climate Protection’ Special Award by the International Astronautical Federation during the Global Space Conference on Climate Change – currently taking place in Oslo, Norway.
Satellites play a vital role in monitoring the rapid changes taking place in the Arctic. Tracking ice lost from the world’s glaciers, ice sheets and frozen land shows that Earth is losing ice at an accelerating rate.
Using information from ESA’s ERS, Envisat and CryoSat satellites as well as the Copernicus Sentinel-1 and Sentinel-2 missions, research led by Tom Slater of the University of Leeds, found that the rate at which Earth has lost ice has increased markedly within the past three decades. Currently, more than a trillion tonnes of ice is lost each year.
To put this into perspective, this is equivalent to an ice cube measuring 10x10x10 km over Oslo’s skyline. Putting it another way, the amount of ice loss globally is equivalent to 12 000 times the annual water use of the Norwegian capital.
The sooner Earth’s temperature is stabilised, the more manageable the impacts of ice loss will be.
Continuity in satellite data is the key to predicting future ice losses, and to assist in mitigating the threats posed by sea-level rise, shrinking high mountain glaciers and further climate feedbacks. The Copernicus Expansion missions, CRISTAL, CIMR and ROSE-L have been designed to fill the gaps in current Sentinel capabilities for comprehensive monitoring of changes in the global ice cover.

Adding to the grim list of record ice losses, record air temperatures and record droughts, which have all hit the headlines recently, the temperature of the surface waters of our oceans is also at an all-time high. With an El Niño looming, concerns are that we will soon be facing even worse extremes. Satellites orbiting overhead are being used to carefully track the patterns that lead up to El Niño to further understand and predict the consequences of this cyclic phenomenon against the backdrop of climate change.

Europe’s latest weather satellite, the Meteosat Third Generation Imager, has just delivered its first view of Earth – revealing conditions over Europe, Africa and the Atlantic in remarkable detail.
When one thinks of the damage that climate change is doing, it’s probable that what comes to mind is a vision of huge lumps of ice dropping off one of the polar ice sheets and crashing into the ocean. While Greenland and Antarctica are losing masses of ice, so too are most of the glaciers around the world, but it’s tricky to measure how much ice they are shedding.
Thanks to ESA’s CryoSat satellite and a breakthrough way of using its data, scientists have discovered that glaciers worldwide have shrunk by a total of 2% in just 10 years, and it’s because of higher air temperatures.
The latest European State of the Climate report states that, last year, Europe suffered its hottest summer on record. The heat and a persistent lack of rain caused drought which, at its peak, affected much of the continent. This not only illustrates the reality of climate change, but also how precarious our supply of freshwater can be, even in western Europe where the climate is relatively moderate.
By delivering frequent and accurate gravity measurements, a new space mission called MAGIC, a cooperation between ESA and NASA, will help make the important task of managing our precious water supplies more efficient.
Global food security is a major challenge in the face of population growth and climate change. One of the first steps in achieving food security for all is to know which crops are growing where and how – each season. Launching today, ESA’s WorldCereal is the world’s first dynamic system capable of providing seasonally updated crop information to help monitor agricultural production across the globe.
A report, released today, states that ice loss from Greenland and Antarctica has increased fivefold since the 1990s, and now accounts for a quarter of sea-level rise.

While we know that we use more water for irrigation than for any other single purpose, watering practices are not monitored worldwide. Water needed for agriculture is expected to further increase as time goes on, so managing this precious resource as effectively as possible is imperative. Scientists have now shown that a nifty way of using information from satellites could pave to way to measuring how much water we use to irrigate, which could subsequently lead to better management.

Have you ever wondered what a volcano looks like from space? Today, we’re counting down our picks of the most impressive volcanoes around the world – captured by satellites. Our countdown includes Mount Fuji, Mount Mayon and Mount Vesuvius. Satellites orbiting 800 km above us can monitor volcanoes. They can provide real-time data on volcanic activity and can even help disaster response efforts post-eruption.
A large mass of Sargassum ‘seaweed’ circling around the Gulf of Mexico may soon wash up along the US west coast near Florida – depending on the right combination of currents and wind. The bloom, which may likely be the largest ever recorded, is so large that it’s visible from space.
New research reveals that ice being lost from glaciers that flow into lakes in the Himalayas has been significantly underestimated. This discovery has critical implications for predicting the demise of the region’s glaciers and for managing critical water resources.
They may be microscopic, but their ability to sequester carbon is phenomenal. We are talking phytoplankton – and scientists working on a project funded by ESA are assessing different aspects of the role that these tiny plants play in the ocean carbon cycle to better understand climate processes.

Runoff and river discharge are important components in Earth’s water cycle, but as climate change tightens its grip, heatwaves and instances of drought are increasingly hitting the headlines. One would assume that this hotter weather leads to reduced water runoff, but an innovative way of using information from satellites suggests that this isn’t always the case.
Europe has just endured its second warmest winter on record. Much of southern and western Europe has been affected by substantial anomalies of soil moisture owing to this exceptionally dry and warm winter. Data from ESA’s Soil Moisture and Ocean Salinity mission have been used to monitor the low levels of soil moisture across Europe.
Honouring individual scientists and teams of scientists that have contributed to the innovative use of Earth observation data, ESA and the European Geosciences Union (EGU) are happy to announce the winners of this year’s prestigious Excellence Award.
The final instalment of the sixth assessment report by the United Nations' Intergovernmental Panel on Climate Change (IPCC) has been released today. The report warns that the planet has already warmed 1.1°C above pre-industrial levels, resulting in more frequent and intense extreme weather events that are causing increasingly dangerous impacts on nature and people in every region of the world.
The report includes a greater contribution of Earth observation data than its previous iterations in providing the physical evidence of Earth’s changing climate system – from sea-level rise, growing greenhouse-gas emissions and melting sea ice.
Tropical forests are vital ecosystems in the fight against climate change. Yet vast areas of forest are still degraded or lost through deforestation and environmental changes. Clement Albergel, Climate Applications Scientist at ESA, explains how satellite observations can not only help us to monitor deforestation, but provide valuable information on secondary and degraded forests as well as how much carbon they accumulate.

The pressure is on to reduce the amount of greenhouse gases we pump into the atmosphere – but the race is also on to support the monitoring that shows if targets are being met. Being developed by ESA on behalf of the EU, the new Copernicus Anthropogenic Carbon Dioxide Monitoring mission, or CO2M for short, is destined to be Europe’s prime mission for monitoring and tracking carbon dioxide emissions from human activity. CO2M is currently planned as a two-satellite mission, each of which will carry a near-infrared and shortwave-infrared spectrometer to measure atmospheric carbon dioxide at high spatial resolution. Engineers at Thales SESO in France explain how the development of some of the mission’s precision measuring and optical components is going.
ESA’s HydroGNSS mission will now comprise two identical satellites to halve the time it takes to revisit the same place on Earth’s surface and re-measure various climate variables such soil moisture. Having two satellites in orbit will significantly improve the science that this exciting new Scout mission will yield.
Like many places, the Antarctic Peninsula is falling victim to rising temperatures. However, when scientists used radar images from the Copernicus Sentinel-1 mission acquired between 2014 and 2021, they were taken aback to discover just how the fast 105 glaciers on the west coast are flowing in the summer months.
Over the last few months, ESA’s Earth Explorer Biomass satellite has been going through a punishing series of tests to make sure that it will survive the unavoidable blasts of noise and shuddering during liftoff. Engineers have now also tested that it will unfold its solar wing in the correct sequence. Coming through all of this with flying colours, Biomass is a few steps closer to its mission in orbit: to deliver completely new information on our precious forests and the carbon they store.
In the 1980s, scientists discovered a gaping hole in Earth's ozone layer, caused by humanmade chemicals. But thanks to the historical Montreal Protocol, the world came together to take bold action to save our planet. Decades later, we can see the steady recovery of the ozone hole. How did we do it? And what does space have to do with it? Join us as we explore the journey of the ozone hole, from its alarming discovery to the incredible strides made to fix it, and how satellites are helping us track its recovery.
