Hot on the heels of the first Earth Observation Commercialisation Forum, now is a good time to take a look at the all-embracing support that ESA gives to the commercial sector in Europe. With funding programmes, business guidance for companies, and multiyear contracts, ESA provides a vital springboard for continued growth in commercial Earth observation.
In a groundbreaking development, researchers from the University of Leeds have unveiled a neural network that can swiftly and accurately chart the expanse of large Antarctic icebergs in satellite images, accomplishing the task in a mere 0.01 seconds. This novel approach is in stark contrast to the laborious and time-consuming manual efforts needed previously.
ESA and the European Commission are joining forces to accelerate the use of Earth-observing satellites and the information they provide to address the pressing challenge of climate change.
This landmark initiative signifies a firm commitment to advancing our understanding of Earth's climate system and enhancing our ability to take timely and informed actions to mitigate and adapt to the impacts of climate change, particularly encompassing the European Green Deal.
ESA’s first Earth Observation Commercialisation Forum took place at ESA Headquarters in Paris on 30–31 October 2023. The event saw investors, institutions, entrepreneurs and different-sized companies from the Earth observation sector come together to discuss the commercial potential and challenges of Earth observation. Revisit the event by watching the streaming replay.

ESA and the Japanese Aerospace Exploration Agency are gearing up for a momentous milestone in Earth observation as launch of the EarthCARE satellite approaches.
Following years of rigorous development and extensive testing, the satellite is now undergoing its final round of tests in Europe before being shipped to the launch site early next year – bringing us one step closer to gaining unprecedented insights into the role that clouds and aerosols play in the climate system.
With a multitude of opportunities for start-ups, established companies and investors, commercial Earth observation is a vibrant sector with fast-moving innovations in technology, datasets and downstream applications. ESA is a key driving force for the development of European Earth observation and provides impetus through its many programmes and initiatives.
To set the scene ahead of ESA’s Earth Observation Commercialisation Forum next week, here is some need-to-know background information on the evolution and state of play of the Earth observation industry.
Copernicus operations resilience: Inuvik wildfires
New research, based largely on information from the Copernicus Sentinel-1 and ESA’s CryoSat satellite missions, has revealed alarming findings about the state of Antarctica's ice shelves: 40% of these floating shelves have significantly reduced in volume over the past quarter-century. While this underscores the accelerating impacts of climate change on the world's southernmost continent, the picture of ice deterioration is mixed.

With many people around the world suffering from various forms of malnutrition it’s important that the absolute basics such as rice, soya and wheat are as nourishing as possible. ESA-funded research shows that the Copernicus Sentinel-2 mission and the Italian Prisma mission could be used to monitor the nutritional content of staple crops. This could, for example, help farmers take appropriate steps to boost the quality of their crops as they grow.

Thanks to their ability to absorb and store carbon dioxide from the atmosphere, forests have long been recognised as a key tool in the fight against climate change – but not all forests are equal. New research based on data from ESA’s SMOS satellite mission has found that, surprisingly, young trees are champions at carbon capture.
Measurements from the Copernicus Sentinel-5P satellite show that this year’s ozone hole over Antarctica is one of the biggest on record. The hole, which is what scientists call an ‘ozone depleting area,’ reached a size of 26 million sq km on 16 September 2023. This is roughly three times the size of Brazil.
In the quest to address climate change and reduce greenhouse gas emissions, detecting methane leaks – a potent contributor to global warming – has become increasingly vital. Researchers are harnessing the capabilities of cutting-edge satellite technology to monitor these leaks from space.
Following the devastating earthquake that struck Morocco on 8 September, satellite data have been made available through the International Charter ‘Space and Major Disasters’ to help emergency response teams on the ground.
In addition, radar measurements from Europe’s Copernicus Sentinel-1 satellite mission are being used to analyse how the ground has shifted as a result of the quake, which will not only help in planning the eventual reconstruction but will also further scientific research.
Are you a creative visionary with a passion for climate action? Enter ESA’s latest competition to showcase your talent by transforming decades of satellite climate data into impactful visuals to help bridge the gap between climate science, policy makers and the wider public. The winner will have the unique opportunity to display their data visualisation at the 2023 United Nations Climate Change Conference (COP28) taking place later this year.
In a significant leap forward for meteorology, the preliminary data obtained by Meteosat Third Generation’s two instruments, the Flexible Combined Imager (FCI) and the Lightning Imager (LI), were successfully combined today for the first time – highlighting their complementary capabilities. This first set of animations gives us a preview of the system’s future impact.
This animation shows the combined observations from the Meteosat Third Generation’s instruments starting at 12:00 UTC on 03 June 2023 and ending at 12:00 UTC of 04 June 2023. Lightning activity is more intense over central Africa, the northern part of South America, Europe and the Middle East.
Cloud and lightning movements are synchronised, following the global circulation patterns (east to west along the Equator, and west to east at higher latitudes). The bright sunglint area, where the Sun's light is reflected by the ocean and small water bodies towards the satellite, traverses from east to west throughout the day.
This is preliminary commissioning data, not for operational use. For more information: A forecasting revolution on its way
Confirmed by the World Meteorological Organization, July 2023 was the hottest month on record, with high-impact weather continuing through August. These records are based on air temperatures, but measurements of the temperature of Earth’s surface taken from space are also essential to tracking the impact of climate change, and to being better prepared for such extremes – especially when it comes to cities where stifling urban heat islands form.
Following on from the launch of the first Meteosat Third Generation weather satellite, MTG-I1, last December, the focus is now on getting its partner satellite, MTG-S1, ready for liftoff next year – and a significant milestone has been reached. The satellite has been equipped with its main instrument, the Infrared Sounder, hence the satellite’s name, and also the Copernicus Sentinel-4 instrument, an ultraviolet, visible, near-infrared light spectrometer, or UVN for short.
According to the World Meteorological Organization, July 2023 is likely to have been the hottest month on record. While much of Europe, North America and Asia suffered the immediate consequences of these brutal temperatures, extreme events are also hitting hard far away in the icy reaches of Antarctica. In a paper published today, scientists highlight Antarctica’s vulnerability to extremes and the role that satellites play in monitoring this remote region.
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.

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 temperatures expected to climb to 48°C on the islands of Sicily and Sardinia – potentially the hottest temperatures ever recorded in Europe.

After exceeding its planned life in orbit, ESA’s Aeolus wind satellite is on its way back to Earth. The satellite is currently falling around 1 km a day, and its descent is accelerating. ESA’s spacecraft operators will soon intervene and attempt to guide Aeolus in a first-of-its-kind assisted reentry. Why is ESA doing this?
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.
Paris Air Show live: From Earth science to climate action
22 June at 12:00 CEST: Earth's water and carbon cycles from space
With commercial companies playing an increasingly important role in creating a dynamic and innovative space industry, nine New Space satellite data suppliers have joined the Copernicus programme as ‘Contributing Missions’. Today, at the Le Bourget Paris Air Show, ESA and the European Commission further embraced the era of New Space by welcoming these nine companies into the fold and celebrating the contribution they will make in monitoring our changing world.
As the current wildfires in Canada show, climate change is increasing the risk and extent of wildfires across the globe. ESA, along with the European Centre for Medium-Range Weather Forecasts have taken a new approach by using realtime observations from ESA’s Soil Moisture and Ocean Salinity satellite mission to better anticipate the outbreak of fires.

Twenty-five years ago, Copernicus set out to transform the way we see our planet. Now, well established as the largest environmental monitoring programme in the world, it returns a whopping 16 terabytes of high-quality data every single day. To mark a quarter-century of European success in space, we look back at a selection of 25 Copernicus highlights.
After very careful consideration, ESA’s Earth Observation Programme Board has taken the decision to terminate the development of CubeMAP as a Scout satellite mission. This decision is based on the development path exceeding the programmatic constraints related to the timeline and budgetary boundaries allocated for this category of New Space mission.
Earth observation has been essential in identifying and monitoring climate change. Satellite data form the baseline for effective European mitigation and adaptation strategies to support the Green Transition, the European Union's Green Deal and the global goal of becoming carbon neutral by 2050.
ESA has now concluded its initial phase of a pilot initiative in Austria that demonstrates the untapped potential of space technologies by providing actionable Earth observation information to accelerate the Green Transition for both society and the economy.

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.

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.
