CryoSat reveals ice loss from glaciers in Alaska and Asia

1.6.2021 9:00   Gulf of Alaska

As our climate warms, ice melting from glaciers around the world is one of main causes of sea-level rise. As well as being a major contributor to this worrying trend, the loss of glacier ice also poses a direct threat to hundreds of millions of people relying on glacier runoff for drinking water and irrigation. With monitoring mountain glaciers clearly important for these reasons and more, new research, based on information from ESA’s CryoSat mission, shows how much ice has been lost from mountain glaciers in the Gulf Alaska and in High Mountain Asia since 2010.

The curious incident of Swarm and sprites in the night-time

18.5.2021 15:00   Sprites seen over the Czech Republic and detected by Swarm

We are all familiar with the bolts of lightning that accompany heavy storms. While these flashes originate in storm clouds and strike downwards, a much more elusive type forms higher up in the atmosphere and shoots up towards space. So, what are the chances of somebody taking photographs of these rarely seen, brief ‘transient luminous events’ at the exact same time as a satellite orbits directly above with the event leaving its signature in the satellite’s data?

Glacier avalanches more common than thought

30.4.2021 11:00   Glacier avalanches in the Sedongpu region, China

One tends to think of mountain glaciers as slow moving, their gradual passage down a mountainside visible only through a long series of satellite imagery or years of time-lapse photography. However, new research shows that glacier flow can be much more dramatic, ranging from about 10 metres a day to speeds that are more like that of avalanches, with obvious potential dire consequences for those living below.

Celebrate Earth Day with ESA

19.4.2021 13:05   Earth Day 2021

At ESA, every day is Earth Day. As we humans continue to subject our home planet to increasing pressures, we are better placed than ever to understand and monitor the consequences of what we inflict. Astronauts onboard the International Space Station give us the human perspective of how beautiful Earth is, while satellites orbiting above return systematic measures to take the pulse of our planet 24 hours a day.

These measurements allow us to understand how Earth works as a system and how human activity is changing natural processes, leading to climate change. This information is fundamental to global climate policy-making through international bodies such as the Intergovernmental Panel on Climate Change and UN Climate Change Conferences, the next being COP26 later this year.

Water mission takes on space weather

24.3.2021 15:20   SMOS turns to the Sun

For well over a decade, ESA’s SMOS satellite has been delivering a wealth of data to map moisture in soil and salt in the surface waters of the oceans for a better understanding of the processes driving the water cycle. While addressing key scientific questions, this exceptional Earth Explorer has repeatedly surpassed expectations by returning a wide range of unexpected results, often leading to practical applications that improve everyday life. Adding to SMOS’ list of talents, new findings show that what was considered noise in the mission’s data can actually be used to monitor solar activity and space weather, which can damage communication and navigation systems.

New long-term dataset to analyse global fire trends

26.1.2021 15:30   Area burned by fire in August 2019

Fire affects an estimated four million square kilometres of Earth’s land each year and is responsible for releasing aerosols and greenhouse gases to the atmosphere. Understanding the influence that this has on atmospheric chemistry and representing these emissions in future climate predictions is, however, complex and remains poorly understood. To improve the situation, a team of scientists working as part of ESA’s Climate Change Initiative is using satellite observations, such as from Copernicus Sentinel-3, to gain a global view of land burned by fire.

Cloud-free crop maps foster sustainable farming

25.1.2021 13:00   Optimising agriculture

The rapidly rising global population, sustainability and climate change are among the challenges the agriculture sector faces in the business of producing food. Fortunately, information from satellites can help. A new commercial service – the first in the world – cleverly combines radar data from Copernicus Sentinel-1 and optical data from Copernicus Sentinel-2 to offer daily maps of field-scale crop biomass. Importantly, these maps are completely unimpeded by cloud cover. This new service allows farmers to better monitor and assess the growth of their produce, and, ultimately, make more effective decisions.

Our world is losing ice at record rate

25.1.2021 11:45   Earth is losing ice at record rate

A research team – the first to carry out a survey of global ice loss using satellite data – has discovered that the rate at which ice is disappearing across the planet is speeding up. The findings also reveal that 28 trillion tonnes of ice was lost between 1994 and 2017 – equivalent to a sheet of ice 100 metres thick covering the whole of the UK.

Loss of Vega flight VV17: Independent Enquiry Commission announces conclusions

17.12.2020 16:51  

Press Release N° 33–2020

On Tuesday, November 17, Arianespace announced the loss of the Vega VV17 mission, which was carrying two payloads, SEOSAT-Ingenio, an Earth-science observation satellite for the European Space Agency (ESA), on behalf of Spain's Center for Development of Industrial Technology (CDTI), and TARANIS for France’s National Centre for Space Studies (CNES). The first three stages functioned nominally until the ignition of the AVUM upper stage, eight minutes after liftoff. At that time, a degraded trajectory was detected, followed by a loss of control of the vehicle and the subsequent loss of the mission.

Long-term permafrost record details Arctic thaw

16.12.2020 10:00   Average ground temperature 2007-2018

Frozen Arctic soils are set to release vast amounts of greenhouse gases to the atmosphere as they continue to thaw in coming decades. Despite concerns that this will fuel future global warming, the scale and speed of this important climate process remain uncertain. To help address this knowledge gap, ESA-funded researchers have developed and released a new permafrost dataset – the longest, satellite-derived permafrost record currently available.

CryoSat reveals surprising ebb and flow of subglacial lakes

14.12.2020 13:50   Thwaites glacier seen by Copernicus Sentinel-2

Hidden from view by ice kilometres thick, there is a vast network of lakes and streams at the base of the Antarctic ice sheet. This subsurface meltwater affects the speed with which the ice sheet flows towards the ocean. Using a decade of altimetry data from ESA’s CryoSat satellite, scientists have made an unexpected discovery about how lakes beneath Thwaites glacier have drained and recharged in quick succession.

Iceberg on collision course with South Georgia

11.12.2020 12:00   Video: 00:02:06

The giant A-68A iceberg could strike land this month – wreaking havoc near the waters of the South Georgia Island.

Since its ‘birth’ in 2017, the iceberg has travelled thousands of kilometres from the Larsen C ice shelf, in Antarctica, and now lies around 120 km from South Georgia. If it remains on its current path, the iceberg could ground in the shallow waters offshore – threatening wildlife, including penguins and seals.

Satellite missions are being used to track the berg on its journey over the past three years. The Copernicus Sentinel-1 radar mission, with its ability to see through clouds and the dark, has been instrumental in mapping the polar regions in winter.
