ESA and UNEP collaborate for a greener future

In a significant step towards a more sustainable future, ESA and the United Nations Environment Programme (UNEP) have signed a Memorandum of Understanding during Earth Information Day at COP28 currently taking place in Dubai.

The memorandum signifies a commitment to harness the power of space technology and data for environmental conservation, nature and biodiversity protection and restoration.

Contract secures next step for TRUTHS climate mission

Delegates from around 200 countries are convened at the United Nations COP28 summit in Dubai to assess the action they are taking to combat the climate crisis. With satellites fundamental to understanding and monitoring climate change, ESA has awarded a contract to Airbus to take the TRUTHS satellite mission to its next development phase.

TRUTHS is set to provide the gold reference for climate measurements, thereby giving decision-makers more confidence in the data they use for climate action.

Global Stocktake: how space drives climate action

Almost 200 countries are gathering in Dubai to attend the biggest climate event of the year. COP28 – the 2023 United Nations climate change summit – isn’t just another conference though. For the first time, country representatives will assess the progress they’ve made towards cutting their greenhouse gas emissions through a process called the ‘global stocktake’.

Satellites are critical in the quest to tackle climate change as they give the robustness and transparency needed to monitor progress towards a lower-emissions and more resilient world. If undertaken effectively, the global stocktake can provide an opportunity to leverage decisions and accelerate ambition in climate action plans.

This video contains interviews with ESA Director of Earth Observation Programmes, Simonetta Cheli, Antony Delavois, ESA Junior Professional, Atmospheric Composition and Yasjka Meijer, CO2M Mission Scientist.

Taking climate action with Earth observation

As global temperatures records are smashed and greenhouse gas emissions reach new highs, a new report from the UN Environment Programme finds that current pledges under the Paris Agreement put the world on track for a 2.5–2.9°C temperature rise this century – pointing to the urgent need for increased climate action.

The report is timely as nearly 200 nations gather in the coming two weeks at the United Nations COP28 Climate Change Summit to conclude the world’s first ever ‘Global Stocktake’ on climate change. Swift and sustained climate action is needed to avoid the worst consequences of climate change. Satellites are critical tools in the quest to tackle climate change and monitor progress towards a lower-emissions and more resilient world.

How will EarthCARE shed light on clouds?

In around six months, ESA’s Earth Cloud Aerosol and Radiation Explorer mission will take to the skies to advance our understanding of the interactions between clouds, aerosols and radiation in Earth’s atmosphere. But how will it do that exactly?

The power of Earth observation

We are all intricately interconnected to our Earth – from the trees that provide us with oxygen, to the natural sources that shape our landscape. ESA's Earth observation programme is at the forefront of monitoring our planet's dynamic changes. Using cutting-edge satellite technology, ESA captures invaluable data on Earth's atmosphere, land and oceans. From tracking climate patterns to assessing environmental health, ESA's Earth observation initiatives provide essential insights for scientific research, environmental management and disaster response. By harnessing space technology, ESA contributes significantly to our understanding of Earth – ensuring a sustainable future for generations to come.

Warming ocean causing rapid glacier retreat

With all eyes about to focus on the COP28 climate conference in Dubai, new scientific findings show, again, that the climate crisis is taking its toll on Antarctica – a continent, up to recently, thought better able to withstand the immediate effects of rising global temperatures.

Using satellite data, scientists have discovered that the ice shelf extending into the ocean from Cadman Glacier on the west Antarctic Peninsula collapsed, leaving the glacier exposed to unusually warm ocean water, which caused the glacier to accelerate and retreat rapidly.

Having satellites in different types of orbit is essential to delivering data to forecast the weather accurately. With the first Meteosat Third Generation Imager satellite safely in geostationary orbit since December 2022, it’s also time to focus on its polar-orbiting cousin, the MetOp Second Generation mission. And now, for the first time, two MetOp Second Generation satellites have been brought together to stand side-by-side for testing.

Monitoring methane emissions from space

Methane is the second most important greenhouse gas contributor to climate change after carbon dioxide. Curbing methane emissions could deliver immediate and long-lasting benefits for the climate, seeing as the gas only lingers in the atmosphere for a relatively short time.

Satellites have a really important role to play in reducing greenhouse gas emissions. The Tropomi instrument onboard the Copernicus Sentinel-5P satellite is the only instrument that maps global methane concentrations every single day. This lets scientists detect hotspots for large methane sources around the world – allowing us to address the consequences of methane emissions on our climate and environment.

Antarctic ice shelf demise

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.

Younger trees champion carbon capture

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.

Ozone hole goes large again

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.

Meteosat Third Generation: painting the full picture

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

Sensing city night heat from space

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.

Antarctica vulnerable to extreme events

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.

Counting wildfires across the globe

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.

Simulating Aeolus’s demise: a bird’s eye view

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.

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: 

• Phase I: once Aeolus has fallen naturally to 280 km, the first manoeuvre is performed – the largest in the mission’s five years in orbit. The main objectives are to lower the satellite down to 250 km and to check how the satellite behaves when executing a large manoeuvre at such low altitudes – more than three times the size of any performed during routine operations.
• Phase II: after three to five days, a series of four manoeuvres will lower Aeolus’s ‘perigee altitude’ – the point in orbit closest to Earth – down to an altitude of about 150 km. 
• Phase III: a final manoeuvre will lower Aeolus to a perigee altitude of 120 km. 
• Phase IV: in the final, shortest phase, Aeolus the spacecraft becomes space debris, completing its final descent in just a few Earth revolutions. 

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.

Litli-Hrútur eruption seen from space

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.

Satellites unveil the far-reaching impact of irrigation

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.

Satellites map aftermath of Emilia-Romagna floods

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.

Replay: Aeolus reentry media briefing

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.

Paris Air Show Live – Session on understanding Earth’s water and carbon cycles from space

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.
