Glacier calving and a whole lot of mixing

It’s no surprise that when a massive lump of ice drops off the edge of a glacier into the sea, the surface waters of the ocean get pretty churned up. However, in addition to causing tsunamis at the surface of the ocean, recent research has led to the discovery that glacier calving can excite vigorous internal tsunami waves – a process that has been neglected in driving ocean mixing in computer models.

New weather satellite fully loaded

With liftoff now scheduled for 13 December, Europe’s first Meteosat Third Generation Imager (MTG-I1) satellite has been fuelled – a critical and extremely hazardous milestone on the road to launch.

Putting a value on ESA’s Aeolus wind mission

Over the last four years, ESA’s Aeolus mission has been delivering unique profiles of Earth’s winds from space, improving operational weather forecasts, climate models and more – all showing that its novel laser technology is advancing science and being used for important practical applications. Adding to the list of Aeolus’ successes, a recent report highlights that the mission has also brought economics benefits to Europe to the tune of €3.5 billion, and that a follow-on mission could more than double this figure.

Earth from Space: Sharm El-Sheikh, Egypt

World leaders, policymakers and delegates from nearly 200 countries have convened in Sharm El-Sheikh over the past two weeks at the COP27 UN Climate Summit. Today we take a closer look at the Egyptian city through the eyes of Copernicus Sentinel-2.

Strengthening InCubed’s role in commercial Earth observation

Commercialisation is universally recognised as essential for the future prosperity of all aspects of the European space sector, and Earth observation is no exception. The ESA InCubed programme, a co-funding initiative that helps entrepreneurs bring their innovative ideas to market, has enjoyed enormous success since the launch of its first activity in 2018 and continues to make a prodigious contribution to commercial Earth observation. The InCubed portfolio includes around 60 activities, with an impressive €63 million invested so far.

At the upcoming ESA Council at Ministerial Level, Member States will have the possibility to further empower InCubed in its far-reaching efforts to foster commercial innovation. The programme proposal makes the case for a wider remit, including a set of new ‘Invest Actions’ designed to help boost the European Earth observation economy and reinforce relationships with the private investor community.

Seasonal changes in Antarctic ice sheet flow dynamics detected for the first time

Certain estimates of Antarctica’s total contribution to sea-level rise may be over, or even underestimated, after researchers detected a previously unknown source of ice loss variability. In a new paper published in The Cryosphere, researchers using Copernicus Sentinel-1 data, found that glaciers feeding the George VI Ice Shelf speed up by approximately 15% during the Antarctic summer. This is the first time that such seasonal cycles have been detected on land ice flowing into ice shelves in Antarctica.

Earth observation inspires global inventiveness

Today our home planet Earth is being more closely monitored than at any time in its history. Some 1 460 Earth-observing satellites have been launched during the last two decades, with Europe’s Copernicus Sentinel fleet in the forefront of environmental data gathering. A new report led by the European Patent Office examining associated patent filings reveals a 1 800% increase in the same period – with European activity comparatively stagnant compared to international competitors.

Satellites detect methane plume in Nord Stream leak

Following unusual seismic disturbances in the Baltic Sea, several leaks were discovered last week in the underwater Nord Stream 1 and 2 gas pipelines, near Denmark and Sweden. Neither pipeline was transporting gas at the time of the blasts, but they still contained pressurised methane – the main component of natural gas – which spewed out producing a wide stream of bubbles on the sea surface.

With the unexplained gas release posing a serious question about the incident’s environmental impact, a suite of complementary Earth observation satellites carrying optical and radar imaging instruments were called upon to characterise the gas leak bubbling in the Baltic.

Europe’s new weather satellite sets sail

New weather satellite on its way to launch

The final pre-launch preparations for the first Meteosat Third Generation (MTG) satellite are underway. The first satellite, called MTG-I1, built by a European industrial consortium led by Thales Alenia Space carries two imagers: an advanced Flexible Combined Imager  and, in a first for Europe, a Lightning Imager that will allow the earlier detection of storms and extreme weather events, as well as improve aviation safety.  

Building on the long-standing partnership between ESA and Eumetsat, the MTG-I1 will be one of six satellites operating in a fleet, of three at a time, to ensure the continuity of data from the previous Meteosat satellites over the next 20 years. The first Meteosat was launched in 1977 and this third generation of spacecraft will be the most advanced yet, with improved image resolution and providing close to real time data for users, or ‘nowcasting’ of fast-developing, high-impact weather.

The launch is currently scheduled for the end of 2022.

Mediterranean Sea hit by marine heatwave

Many parts of Europe saw record-breaking temperatures over the summer, but it wasn’t just the continental mainland that was affected: the Mediterranean Sea also suffered a major marine heatwave. An ESA-funded project, CAREHeat, detected one of the most intense Mediterranean marine heatwaves observed during the satellite era – with sea surface temperatures reaching 5°C higher than average.

Zooming in on drought from space

We are all aware that the summer of 2022 has been one of the hottest on record, causing drought and raging wildfires in many parts of Europe. Satellite data have been used to report the baking temperatures of the land surface and map fires, but the Copernicus Sentinel-1 radar mission has also been used to zoom in and provide very high-resolution measurements of the actual moisture content of the surface soils. Maps of northern Italy, for example, show how dry this summer has been compared to two years ago.

How do satellites monitor the ozone layer?

The ozone layer in our upper atmosphere protects Earth from the harmful effects of ultraviolet radiation. The use of human-produced chemicals in our atmosphere used for many years depleted Earth’s ozone layer. However, the reduction in the consumption of ozone-depleting substances driven by the Montreal Protocol – an international treaty designed to protect the ozone layer – has allowed for the ozone hole to slowly recover. This global agreement demonstrates the power of international commitment and immediate global action in protecting our environment.

ESA has been involved in monitoring the ozone for over two decades. Today, 16 September, marks the International Day for the Preservation of the Ozone Layer and we take a closer look at how satellite instruments carefully monitor the ozone layer over the South Pole.

Earth from Space: UK heatwave

This summer, heatwaves struck Europe, North Africa, the US and Asia with temperatures reaching over 40°C in places – breaking many long-standing records. Images from the Copernicus Sentinel-3 mission show the scale of Britain’s heatwave as it baked in extreme temperatures in August.

Taking the dazzle out of CryoSat yields a first

Since it was launched more than 12 years ago, ESA’s CryoSat ice mission has dazzled by way of its sheer technological and scientific excellence. This superb Earth Explorer satellite has returned a wealth of information that has transformed our understanding of Earth’s ice and how it is responding to climate change. In some circumstances, however, being dazzled isn’t a good thing, particularly when it comes to measuring the height of sea ice from space during the summer.

A paper published in Nature describes how scientists have now found an ingenious way of removing the pesky problem of dazzle from surface meltwater to yield the first ever continuous, year-round, altimetry measurements of sea-ice thickness in the Arctic Ocean.

Mission ends for Copernicus Sentinel-1B satellite

On 23 December 2021, Copernicus Sentinel-1B experienced an anomaly related to the instrument electronics power supply provided by the satellite platform, leaving it unable to deliver radar data. Since then spacecraft operators and engineers have been working tirelessly to rectify the issue. Unfortunately, despite all concerted efforts, ESA and the European Commission announce that it is the end of the mission for Sentinel-1B. Copernicus Sentinel-1A remains fully operational and plans are in force to launch Sentinel-1C as soon as possible.

Utah’s Great Salt Lake is disappearing

Utah’s Great Salt Lake dropped to its lowest recorded water level last month as a megadrought persists across the US southwest, forcing the fast-growing city to curb its water use. From space, satellite images show how water levels have fallen from 1985 to 2022 – exposing large expanses of lakebed.

Operation centres in tune for upcoming weather satellite

In just a few months’ time Europe’s first Meteosat Third Generation satellite will soar into the skies on an Ariane 5 rocket from French Guiana. From geostationary orbit, this new satellite, carrying two new highly sensitive instruments, will take weather forecasting to the next level. Taking a significant step towards launch, the satellite operations teams at two different centres have completed an all-important suite of tests ensuring that their procedures are fully compatible with the satellite.

EarthCARE taking wing

Tap into Europe in motion

Any movement beneath our feet – from barely perceptible subsidence to the sudden appearance of a sinkhole or a crashing landslide – spells big trouble. Even relatively modest subsidence can weaken buildings and infrastructure and lead to issues such as flooding, and at worst the abrupt disappearance of sections of land brings immediate threat to life. Monitoring and predicting our shifting land is clearly essential for adopting mitigating strategies.

And now, thanks to Europe’s environmental Copernicus programme and the Sentinel-1 radar satellite mission, the first Europe-wide subsidence and soil movement analysis service is available to the public.

EarthCARE takes a big stretch

ESA’s upcoming EarthCARE satellite mission has just taken a big stretch. Engineers have gently unfolded this new satellite’s huge five-panel solar wing to test that it will deploy correctly once it is in space. The solar wing is a critical part of the satellite, providing the energy for EarthCARE to do its job: to quantify the role that clouds and aerosols play in heating and cooling Earth’s atmosphere.

Satellites are essential for delivering key data to understand and monitor how the climate crisis is impacting our world, but, in turn, decision-makers need to be confident in the data they use for mitigation strategies and policymaking. TRUTHS, a new ESA mission, will do just this – and, now having passed an important milestone, it is one step closer to becoming a reality.

Feeling the heat from space

With searing temperatures and a string of record highs being smashed across western Europe, the current heatwave is all too apparent. Extreme heat warnings have been issued in several countries including France, Spain and Portugal, and deadly wildfires have forced thousands to flee their homes. The satellite images here are an example of how the crisis is being viewed by satellites orbiting Earth.

City heat extremes

With air temperatures in excess of 10°C above the average for the time of year in parts of Europe, the United States and Asia, June 2022 has gone down as a record breaker. The fear is that these extreme early-season heatwaves are a taste of what could soon be the norm as climate change continues to take hold. For those in cities, the heat dissipates slower creating ‘urban heat islands’, which make everyday life even more of a struggle.

An instrument, carried on the International Space Station, has captured the recent land-surface temperature extremes for some European cities, including Milan, Paris and Prague.

Methane levels surged in 2020 despite lockdowns

Levels of methane, the second most important greenhouse gas in our atmosphere, continued their unrelenting rise in 2020 despite the economic slowdown caused by the COVID-19 pandemic.

A team of scientists, from the University of Leeds, have used data from the Copernicus Sentinel-5P satellite to pinpoint locations with large surges of methane emissions. These findings were presented during ESA’s Living Planet Symposium which took place last month in Bonn, Germany.

Charting sea level from space

Satellite images of our planet have become essential to our survival, offering a new outlook of our world. With rising seas being one of the biggest threats to society, satellite altimeter missions such as Copernicus Sentinel-6 are essential in monitoring global and regional changes in sea level.

Unbeknown to many, the island of Crete, Greece, plays an important role in the Copernicus satellite altimetry constellation and on an international stage. Satellite altimetry data have to be continuously monitored at the ESA’s Permanent Facility for Altimetry Calibration where different techniques have pioneered the use of transponders to provide the best measurements to validate satellite altimeters in space soon after launch.

This documentary explains how measurements are taken from the top of the White Mountains to make sure users get the best data on sea height from satellite altimetry.

It features interviews with Craig Donlon, Head of ESA’s Earth Surfaces and Interior Earth and Mission Science Division and Stelios Mertikas, Director of Laboratory of Geodesy & Geomatics Engineering at the Technical University of Crete.

Living Planet concludes with record numbers

With more than 5000 participants, 240 science sessions and over 1300 oral presentations, ESA’s Living Planet Symposium comes to a close with record-breaking numbers. Held on 23-27 May at the World Conference Center in the German city of Bonn, the symposium brought together world-class scientists, business leaders, representatives from space agencies and international organisations and industry from around the world. Throughout the week, they showcased the latest advances in Earth observation and highlighted the essential role of Earth observation for decision making regarding the ongoing climate crisis. As the week draws to a close, we look back at some of the highlights of the week.

Boosting commercial Earth observation

One of the objectives of the Living Planet Symposium, taking place this week in Bonn, is to foster interaction between the institutional and commercial sectors to boost the Earth observation space economy. This is being achieved by highlighting existing partnerships, expanding the number of data users and facilitating access to private funds for companies.

Oceans and Climate

Earth’s oceans are huge heat stores, soaking up 93% of the excess heat from human activity over the past 70 years. Ocean currents redistribute heat around the planet, from the Equator to the poles. Where this ocean heat goes influences weather patterns and regional climate. As well as absorbing heat, oceans are a natural carbon sink, absorbing a quarter of carbon dioxide emissions from human activity. This has led to the acidification of ocean water, threating marine life.
The amount of heat and carbon dioxide absorbed depends on a number of ocean variables, all of which can be measured from space.

Taking climate monitoring into the future with quantum

Over the last decades, satellites measuring the many aspects of Earth have certainly demonstrated their worth with the information they yield to understand and monitor our environment and, importantly, to provide undeniable evidence of climate change for policymaking. While Europe is currently firmly placed as a world leader in Earth observation, it’s critical to stay ahead of the game by examining how even more sophisticated space technologies can be developed to return even more precise information in the future. Today, at ESA’s Living Planet Symposium, being held in Bonn, scientists dug deep into the potential of spaceborne quantum gravity sensors to do just this.

Water cycle

Imagine the world without water: as cold and lifeless as the planet Mars. Earth is unique in our solar system in being able to sustain liquid water on its surface. Water is essential for life and for Earth’s climate, helping transport heat around the planet, but it is difficult to track through the whole water cycle. The global view offered by satellites helps. ESA’s Climate Change Initiative is looking at a range of climate variables linked to the water cycle.

Putting the future in FutureEO

With scientific excellence at the very heart of ESA’s FutureEO programme, participants at this week’s Living Planet Symposium have been making it clear that new research missions to advance Earth science must continue to be realised in the future.

What can satellites reveal about climate tipping points?

The effects of our warming climate are seen across a multitude of measures, usually as incremental changes: more frequent extreme weather, heatwaves, droughts and wildfires. The cumulative impact of these changes, however, can cause fundamental parts of the Earth system to change more quickly and drastically. These ‘tipping points’ are thresholds where a tiny change pushes the system into an entirely new state.

This week, at ESA’s Living Planet Symposium, scientists came together to discuss the latest research evidence for climate tipping points and identify the opportunities and challenges of using remote sensing data to understand them.
