Living Planet Symposium Extra News: Day 5

27.6.2025 13:45   Land-surface temperature in Nevada and California

ESA’s Living Planet Symposium came to a close today, concluding a week of networking, discussions and meeting of curious, scientific minds.   

Today, one of the focal points was thermal imaging instruments, which are critical for monitoring land-surface temperature – and will be carried on upcoming missions such as the upcoming Copernicus Land Surface Temperature Mission. ESA’s Soil Moisture and Ocean Salinity (SMOS) mission celebrated passing its 15-year milestone in orbit – the mission has helped improve weather and climate models. Three new contracts were signed for ESA’s InCubed programme, which is central to the agency’s efforts to turn promising concepts into successful Earth observation services, strengthening Europe’s position in this rapidly evolving sector. 

Swarm in tune with atmospheric hot flushes

27.6.2025 9:44   Atmospheric hot flush during a solar storm

Scientists are harnessing data from ESA’s Swarm mission and ground-based instruments to precisely measure the strength and duration of intense upper-atmosphere heating – dramatic ‘hot flushes’ triggered by solar storms that also cause Earth’s tenuous outer atmospheric layers to expand rapidly.

This research, funded by ESA's Earth Observation FutureEO Science for Society initiative, offers crucial insights into how geomagnetic activity affects satellite orbits and space weather conditions.

Living Planet Symposium Extra News: Day 4

High-resolution mapping reveals ocean carbon sink detail

25.6.2025 14:15   Ocean acidification is detrimental to coral reefs

As atmospheric carbon dioxide levels continue to rise, the ocean plays a crucial role in helping to reduce the full impact of human-driven climate change by absorbing roughly a quarter of the carbon dioxide emitted by human activity. However, this uptake is far from uniform across the global ocean. A new satellite-based product can now map the ocean carbon sink at unprecedented resolution, offering unique insights into this highly variable and complex component of Earth’s climate system. 

First sea-level records for coastal community protection

25.6.2025 11:00   Majuro, Marshal Islands, is at risk from sea-level rise

While satellites have revolutionised our ability to measure sea level with remarkable precision, their data becomes less reliable near coasts – where accurate information is most urgently needed. To address this critical gap, ESA’s Climate Change Initiative Sea Level Project research team has reprocessed almost two decades of satellite data to establish a pioneering network of ‘virtual’ coastal stations. These stations now provide, for the first time, reliable and consistent sea-level measurements along coastlines.

Biomass launch highlights

29.4.2025 18:30   Video: 00:02:59

ESA’s state-of-the-art Biomass satellite launched aboard a Vega-C rocket from Europe’s Spaceport in Kourou, French Guiana. The rocket lifted off on 29 April 2025 at 11:15 CEST (06:15 local time).

In orbit, this latest Earth Explorer mission will provide vital insights into the health and dynamics of the world’s forests, revealing how they are changing over time and, critically, enhancing our understanding of their role in the global carbon cycle. It is the first satellite to carry a fully polarimetric P-band synthetic aperture radar for interferometric imaging. Thanks to the long wavelength of P-band, around 70 cm, the radar signal can slice through the whole forest layer to measure the ‘biomass’, meaning the woody trunks, branches and stems, which is where trees store most of their carbon.

Vega-C is the evolution of the Vega family of rockets and delivers increased performance, greater payload volume and improved competitiveness.

ESA’s state-of-the-art Biomass satellite has launched aboard a Vega-C rocket from Europe’s Spaceport in French Guiana. The rocket lifted off on 29 April 2025 at 11:15 CEST (06:15 local time).

In orbit, this latest Earth Explorer mission will provide vital insights into the health and dynamics of the world’s forests, revealing how they are changing over time and, critically, enhancing our understanding of their role in the global carbon cycle. It is the first satellite to carry a fully polarimetric P-band synthetic aperture radar for interferometric imaging. Thanks to the long wavelength of P-band, around 70 cm, the radar signal can slice through the whole forest layer to measure the ‘biomass’, meaning the woody trunks, branches and stems, which is where trees store most of their carbon.

Vega-C is the evolution of the Vega family of rockets and delivers increased performance, greater payload volume and improved competitiveness.

A new era of forest monitoring is quite literally taking off, ushering in what scientists are calling the ‘forest space age’. On April 29, ESA will launch its revolutionary Biomass mission, the first satellite to carry a P-band radar into space – technology that is set to transform how we understand forests and the carbon they store. Along with other space agencies’ instruments already in orbit or soon to be launched, there has never been so many ‘eyes in the sky’ focused on forests.

Yet, the work of people on the ground –often in the most remote and challenging forest regions – also remains essential.

This Copernicus Sentinel-2 image shows part of one of the world’s natural wonders – the Great Barrier Reef in the Coral Sea off the east coast of Queensland, Australia.

Zoom in to explore this image at its full resolution or click on the circles to learn more. 

The Great Barrier Reef extends for nearly 2300 km and covers an area of more than 344 000 sq km, approximately the size of Italy. It is the largest living organism on Earth and the only living thing the naked eye can see from space.

Despite its name, the Great Barrier Reef is not a single reef, but an interlinked system of about 3000 reefs and 900 coral islands, divided by narrow passages. An area of biodiversity equal in importance to tropical rainforests, the reef hosts more than 1500 species of tropical fish, 400 types of coral, hundreds of species of bird and seaweed and thousands of marine animals, including sharks, barracuda and turtles.

In recognition of its significance the reef was made a UNESCO World Heritage Site in 1981.

The section of reef seen here is the southern part off the coast of the Shire of Livingstone in Central Queensland. Part of the mainland and the islands surrounding the coast are visible in the bottom left corner. The tan-coloured sea along the coasts is due to sediment in the water.

A chain of small coral islands can be seen scattered across the centre of the image. The blue hues of the coral contrast with the dark waters of the Coral Sea.

Part of the reef is covered by clouds dominating the upper part of the image. The clouds form a surprisingly straight line, also visible as a distinct shadow cast over the islands below.

Coral reefs worldwide suffer regular damage due to climate change, pollution, ocean acidification and fishing. Furthermore, they are increasingly under threat from coral bleaching, which occurs when the algae that makes up the coral die, causing it to turn white. This phenomenon is associated with increased water temperatures, low salinity and high sunlight levels.

While these coral reefs are ecologically important, they are difficult to map from survey vessels or aircraft because of their remote and shallow location. From their vantage point in space, Earth-observing satellites such as Copernicus Sentinel-2, offer the means to monitor the health of reefs across the globe.

How hidden lakes threaten Antarctic Ice Sheet stability

3.4.2025 10:00   Thwaites Glacier from Sentinel-1

For decades, satellites have played a crucial role in our understanding of the remote polar regions. The ongoing loss of Antarctic ice, owing to the climate crisis, is, sadly, no longer surprising. However, satellites do more than just track the accelerating flow of glaciers towards the ocean and measure ice thickness.

New research highlights how ESA’s CryoSat mission has been used to uncover the hidden impact of subglacial lakes – vast reservoirs of water buried deep under the ice – that can suddenly drain into the ocean in dramatic outbursts and affect ice loss.
