First Earth observation satellite with AI ready for launch

A few months from now will see the launch of the first European satellite to demonstrate how onboard artificial intelligence can improve the efficiency of sending Earth observation data back to Earth. Dubbed ɸ-Sat, or PhiSat, this revolutionary artificial intelligence technology will fly on one of the two CubeSats that make up the FSSCat mission – a Copernicus Masters winning idea.

Tracing the environmental impacts of supply chains

Globalisation and international trade allow us to consume produce from all over the world. But this comes at a cost to the environment – but, for the first time, satellite data combined with artificial intelligence is being usedtoprovide information to assess the impact of global supply chains.

Using machine learning for rewilding

There may not be an obvious connection between rewilding and machine learning, but as highlighted today at ESA’s ɸ-week, a project in the Netherlands uses satellite data and new digital technology to understand how a nature reserve responds to the pressure of being grazed by herbivores.

Using artificial intelligence to automate sea-ice charting

Reliable maps of sea-ice conditions and forecasts are of vital importance for maritime safety, safe navigation and planning. The continued retreating and thinning of Arctic sea ice calls for a more effective way of producing detailed and timely ice information – which is where artificial intelligence  comes in.

CryoSat conquers ice on Arctic lakes

The rapidly changing climate in the Arctic is not only linked to melting glaciers and declining sea ice, but also to thinning ice on lakes. The presence of lake ice can be easily monitored by imaging sensors and standard satellite observations, but now adding to its list of achievements, CryoSat can be used to measure the thickness of lake ice – another indicator of climate change.

Washed up: Sargassum blankets beaches

Over the last month, massive quantities of the Sargassum seaweed have been washing up on the shores of Mexico, Florida in the US and some Caribbean islands, creating a serious environmental problem and causing havoc for the tourist industry. ESA has been tracking this slimy infestation from space.

Expanding our knowledge of Arctic Ocean bathymetry

Our knowledge of the depth and shape of the Arctic Ocean floor – its bathymetry – is insufficient. Owing to year-round sea-ice coverage and the cost of research in this remote region, much of the Arctic Ocean’s bathymetry has remained a mystery, until now.

Second laser boosts Aeolus power

ESA’s Aeolus satellite, which carries the world’s first space Doppler wind lidar, has been delivering high-quality global measurements of Earth’s wind since it was launched almost a year ago. However, part of the instrument, the laser transmitter, has been slowly losing energy. As a result, ESA decided to switch over to the instrument’s second laser – and the mission is now back on top form.

Monitoring Earth’s skin heat for crops and climate

A bright red twin-engined aircraft, equipped with ultra-high-resolution thermal imaging technology has been scouring the agricultural heartlands of Europe this summer. It was no search and rescue exercise, but an initial step towards building a proposed new satellite system capable of recording the temperature of Earth’s skin in intricate detail.

Using satellite information to help rebuild after a disaster

ESA and the Asian Development Bank have joined forces to help the Indonesian government use satellite information to guide the redevelopment following the earthquake and tsunami that devastated the provincial capital of Palu and surroundings last year.

Modelling tides in the Arctic Ocean

We are all aware of the ebb and flow of the tide every day, but understanding tidal flow is important for a range of maritime activities and environmental monitoring, such as search and rescue operations, shipping routes and coastal erosion. The Arctic Ocean tides are particularly difficult to understand, but a new tidal model produced using ESA satellite data may shed some light on what is happening in this remote area.

What’s happening to Greenland’s ice?

Heatwave conditions catapulted Greenland into an early Arctic summer in June, prompting widespread melting across its icesheet surface, according to researchers at the Danish Meteorological Institute.

Snow grain size – it matters

Most of us probably wouldn’t think of describing snow in terms of its grain size. However, grain size is fundamental to the amount of sunlight that snow reflects back into space – its albedo. With both snow and albedo part of the climate system, scientists are applying a novel analytical theory to Copernicus Sentinel-3 data and shedding new light on Greenland’s changing albedo.

TRUTHS: a new potential ESA Earth Watch mission

Satellites yield insight into not so permanent permafrost

Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth’s surface. Ground that has been frozen for thousands of years is also thawing, adding to the climate crisis and causing immediate problems for local communities.

A quarter of glacier ice in West Antarctica is now unstable

By combining 25 years of ESA satellite data, scientists have discovered that warming ocean waters have caused the ice to thin so rapidly that 24% of the glacier ice in West Antarctica is now affected.

Take a deep breath

The air we breathe

Air pollution is a global environmental health problem, especially for those living in urban areas. Not only does it negatively impact our ecosystems, it considerably affects our health. According to the World Health Organization (WHO), around 8 million premature deaths per year are linked to air pollution, more than double of previous estimates.

Where science meets art

World Space Alliance kicks off

While scientists and data users continue to discuss the latest findings about our changing world and the space technologies that are needed to learn more, this week’s Living Planet Symposium has also been the forum to forge and strengthen alliances. And, today sees the start of a two-year pilot for the ESA–SAP World Space Alliance.

Monitoring Earth’s shifting land

The monitoring of land subsidence is of vital importance for low-lying countries, but also areas which are prone to peculiar ground instability.

3D Earth in the making

A thorough understanding of the ‘solid Earth’ system is essential for deciphering the links between processes occurring deep inside Earth and those occurring nearer the surface that lead to seismic activity such as earthquakes and volcanic eruptions, the rise of mountains and the location of underground natural resources. Thanks to gravity and magnetic data from satellites along with seismology, scientists are on the way to modelling inner Earth in 3D.

The global thaw

Water cycle wrapped

As our climate changes, the availability of freshwater is a growing issue for many people around the world. Understanding the water cycle and how the climate and human usage is causing shifts in natural cycling processes is vital to safeguarding supplies. While numerous satellites measure individual components of the water cycle, it has never been described as a whole over a particular region – until now.

Tug-of-war drives magnetic north sprint

As far as we know, Earth’s magnetic north has always wandered, but it has recently gained new momentum and is making a dash towards Siberia at a pace not seen before. While this has some practical implications, scientists believe that this sprint is being caused by tussling magnetic blobs deep below our feet.

Mapping salty waters

The length and precision with which climate scientists can track the salinity, or saltiness, of the oceans is set to improve dramatically according to researchers working as part of ESA’s Climate Change Initiative.

New potential for tracking severe storms

Even just within the last couple of months, Cyclones Fani, Idai and Kenneth have brought devastation to millions. With the frequency and severity of extreme weather like this expected to increase against the backdrop of climate change, it is more important than ever to forecast and track events accurately. And, an ESA satellite is helping with the task in hand.

Jakobshavn Isbrae Glacier bucks the trend

Our planet works in mysterious ways. We are all used to hearing about the world’s ice being the first casualty of climate change and, indeed, it is declining fast. However, recent findings show that one glacier is not conforming to the norm – it’s actually been flowing more slowly and getting thicker.

Joining forces on Earth science to benefit society

With human activity leaving its indelible mark on the landscape and affecting the climate, our natural world is changing faster than at any other time in history. Science is fundamental to understanding environmental change so that these huge challenges can be tackled. To ensure a more efficient approach on Earth-system science and to bring direct benefits to society, ESA and the European Commission are working to join forces.

Spotlight on the pulse of our planet

Satellites deliver crucial information to help solve what is our biggest global problem: climate change. As well as taking the pulse of our planet, satellite data are used in a myriad of daily applications, and are also used increasingly in business. It’s no surprise then that over 4 000 people have flocked to Milan to hear the latest scientific findings on Earth’s natural processes and global change, and to learn about the wealth of new opportunities that Earth observation has to offer.
