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.

Video: 00:12:21 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 altimeters 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 Permanent Facility for Altimetry Calibration where different techniques have pioneered the use of transponders 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.

For the first time ever recorded, in the late summer of 2021, rain fell on the high central region of the Greenland ice sheet. This extraordinary event was followed by the surface snow and ice melting rapidly. Researchers now understand exactly what went on in those fateful summer days and what we can learn from it.

Hundreds of satellite images spanning 30 years have been compiled to show the evolution of the Danube Delta – the second largest river delta in Europe. These findings were presented today at ESA’s Living Planet Symposium taking place this week in Bonn, Germany. View the full article

With well over 4000 scientists, academics, space industry personnel, institutional stakeholders, data users, students and citizens all gathered at the Living Planet Symposium, this world-renowned Earth observation event is already proving to be a bit like magic, especially after the gruelling two-year COVID pandemic. However, there’s also another kind of magic in the air creating a buzz – no, not the band Queen singing their hit single, but a potential new satellite mission called MAGIC that would shed new light on where Earth’s water is stored and how it moves from place to place.

Global climate change is the single most challenging issue faced by humanity – affecting every region, continent and ocean on Earth. It fuels a range of other top-level challenges such as food security, migration, biodiversity loss, risks to human health and economic losses. This week, at ESA’s Living Planet Symposium taking place in Bonn, high-level ESA representatives, along with a mix of academia and policy experts, came together to discuss ESA’s ‘Space for a Green Future Accelerator’ – a major ESA initiative aiming to accelerate the use of space in Europe.

While volcanic eruptions and earthquakes serve as immediate reminders that Earth’s insides are anything but tranquil, there are also other, more elusive, dynamic processes happening deep down below our feet. Using information from ESA’s Swarm satellite mission, scientists have discovered a completely new type of magnetic wave that sweeps across the outermost part of Earth’s outer core every seven years. This fascinating finding, presented today at ESA’s Living Planet Symposium, opens a new window into a world we can never see. View the full article

ESA’s Living Planet Symposium has opened with a flourish with over 4000 participants including scientists, academics, space industry representatives, institutional stakeholders, data users, students and citizens gathered to discuss the latest findings on our changing planet, as well as advances in satellite technologies, new opportunities in the commercial world, and ESA’s plans for the future.

Astronauts live and work in orbit along with teaming populations of microorganisms, which could present a serious threat to health – and even the structural integrity of spacecraft. To help combat such invisible stowaways, an ESA-led project is developing microbe-killing coatings suitable for use within spacecraft cabins. View the full article

Video: 00:04:49 “ESA’s Juice mission has entered its final phase of development, with the spacecraft moving to an Airbus Defence & Space facility in Toulouse, France, for the next round of testing. The spacecraft has been fully integrated, and these tests will be done in full flight configuration, as Juice is scheduled for launch from Europe’s Spaceport in Kourou, French Guiana, in April 2023 The Juice mission is a perfect example of collaboration between several national space agencies and European industry. Its objective is to explore the gas giant Jupiter, its environment, and three of its moons: Europa, Callisto and Ganymede. By studying this planetary system, ESA hopes to learn more about the icy worlds around Jupiter and the origins and possibility of life in our Universe This report includes interviews of: Manuela Baroni, Juice AIT & Launcher Interface Engineer, ESA (English & Italian) Cyril Cavel, Juice Project Manager, Airbus Defence & Space (English) Access the related broadcast quality material.

Video: 00:04:30 On 26 March and enduring temperatures of some 500 degrees Celsius from within the orbit of planet Mercury, Solar Orbiter returned spectacular imagery of the Sun during its first close encounter with our home star. Detailed new movies show activity in the solar atmosphere and reveal a variety of features, including something scientists are nicknaming ‘the hedgehog’ with spikes of hot gas reaching out in all directions. Solar Orbiter’s ten science instruments are now all working together for the first time. Some are looking at the Sun while others are simultaneously measuring the environment around the spacecraft, enabling scientists to join the dots from what they see happening at the Sun, to what Solar Orbiter ‘feels’ at its location in the solar wind millions of kilometres away. In the weeks around the close approach Solar Orbiter also observed several flares and even a coronal mass ejection, providing a taste of space weather forecasting at Earth. Scientists across Europe – and ESA’s partners around the world – are now working to interpret the vast amount of information Solar Orbiter is sending back that promises to transform our understanding of our nearest star. Solar Orbiter is a space mission of international collaboration between ESA and NASA. This report includes interviews with: - David Berghmans, EUI Principal Investigator - Daniel Müller, Solar Orbiter Project Scientist, ESA - Anik De Groof, Instrument Operations Scientist, ESA View the full article

Powerful flares, breathtaking views across the solar poles, and a curious solar ‘hedgehog’ are amongst the haul of spectacular images, movies and data returned by Solar Orbiter from its first close approach to the Sun. Although the analysis of the new dataset has only just started, it is already clear that the ESA-led mission is providing the most extraordinary insights into the Sun’s magnetic behaviour and the way this shapes space weather.

Video: 00:01:00 ESA’s Gaia space telescope revolutionises our understanding of the Milky Way. It scans the sky to measure the position, movement, distance, and characteristics of billions of stars. It is creating the most precise map of our home galaxy yet, providing clues to its origin and evolution. Gaia not only studies the stars, but also what is in between them, as well as asteroids and planetary moons in our Solar System, binary stars and exoplanets, and quasars and galaxies outside of the Milky Way. Gaia provides us with a wealth of data, giving us a new sense of our place in the Universe. Gaia’s data release 3 will be made public on 13 June 2022: https://www.cosmos.esa.int/web/gaia/data-release-3 View the full article
