Iceberg larger than London breaks off Brunt


Image/photo Video: 00:04:25
An iceberg around the size of Greater London broke off Antarctica’s Brunt Ice Shelf due to a natural process called ‘calving’. The iceberg, measuring 1550 sq km, detached from the 150 m-thick ice shelf a decade after scientists first spotted massive cracks in the shelf.

The Sample Transfer Arm – A helping hand for Mars




Giant iceberg breaks away from Antarctic ice shelf


Sentinel-2 captures Antarctica’s new iceberg
Satellite imagery confirms an enormous iceberg, around five times the size of Malta, has finally calved from Antarctica’s Brunt Ice Shelf. The new berg, estimated to be around 1550 sq km and around 150 m thick, calved when the crack known as Chasm-1 fully extended northwards severing the west part of the ice shelf.

This crack was first revealed to be extending in early 2012 after having been dormant for some decades. After several years of desperately clinging on, image data from the Copernicus Sentinel missions visually confirm the calving event.

Radar images capture new Antarctic mega-iceberg


Image/photo Video: 00:00:23
Using radar images from the Copernicus Sentinel-1 mission, the animation shows the A81 iceberg breaking away from the Brunt Ice Shelf on 25 January 2023. The new berg is estimated to be around 1550 sq km, which is around the size of Greater London, and is approximately 150 m thick. It calved when the crack known as Chasm-1 split northwards severing the west part of the ice shelf.

The white square indicated the final breakpoint near the McDonald Ice Rumples.

Routine monitoring from satellites offers unparalleled views of events happening in remote regions. The Copernicus Sentinel-1 mission carries radar, which can return images regardless of day or night and this allows us year-round viewing, which is especially important through the long, dark, austral winter months.

New Galileo service set to deliver 20 cm accuracy


Galileo constellation
Galileo’s capabilities have grown with the addition of a new High Accuracy Service, freely available worldwide to anyone with a suitably equipped receiver. Delivering horizontal accuracy down to 20 cm and vertical accuracy of 40 cm, the High Accuracy Service is enabled through an additional level of real-time positioning corrections, delivered through a new data stream within the existing Galileo signal.

Webb unveils dark side of pre-stellar ice chemistry


Image/photo
The discovery of diverse ices in the darkest, coldest regions of a molecular cloud measured to date has been announced by an international team of astronomers using the NASA/ESA/CSA James Webb Space Telescope. This result allows astronomers to examine the simple icy molecules that will be incorporated into future exoplanets, while opening a new window on the origin of more complex molecules that are the first step in the creation of the building blocks of life.

Future-proofing ice measurements from space


Flying for CryoSat and ICESat-2 in Antarctica
With diminishing ice one of the biggest casualties of our warming world, it’s imperative that accurate measurements continue to be made for scientific research and climate policy, as well as for practical applications such as ship routing. To ensure that ESA and NASA are getting the best out of their ice-measuring satellites and to help prepare for Europe’s new CRISTAL satellite, the two space agencies along with the British Antarctic Survey and a team of scientists teamed up recently to carry out an ambitious campaign in Antarctica.

Looking back at the eruption that shook the world


Hunga Tonga–Hunga Haʻapai eruption
One year ago, the Hunga Tonga-Hunga Ha’apai volcano erupted, causing widespread destruction to the Pacific Island Nation of Tonga, spewing volcanic material up to 58 km into the atmosphere. It brought a nearly 15 m tsunami that crashed ashore, destroying villages, and creating a sonic boom that rippled around the world – twice.

Satellites orbiting Earth scrambled to capture images and data of the aftermath of the disaster. Almost a year later, you can now listen to a sonification of the largest eruption of the 21st Century, created using wind data from ESA’s Aeolus mission.

XMM-Newton spies black holes eating the same stars again and again

Two teams of astronomers using ESA’s XMM-Newton space telescope have observed repeated outbursts of light from inactive black holes that partially destroy stars again and again. This discovery is unexpected, since outbursts of black holes usually appear only once when a black hole consumes a star.

ESA Preview 2023

At the start of 2023 the European Space Agency ESA is happily looking forward to another year filled with a host of thrilling new missions, cutting edge science and the continued effort to guarantee independent access to space for Europe. We will see the first images of the first Meteosat Third Generation satellite, the launch of the Jupiter Icy Moons Explorer, and of Euclid and another Sentinel-1 satellite launch. It will also be the year of Ariane 6 which will make its inaugural flight and the first Dane in space, Andreas Mogensen will return to the ISS as the new astronaut-candidates commence their training. Near the end of the year the second Space Summit will further cement ESA’s ambitions for Space in Europe.

Sentinel-1 and AI uncover glacier crevasses


Thwaites Glacier
Scientists have developed a new Artificial Intelligence, or AI, technique using radar images from Europe’s Copernicus Sentinel-1 satellite mission, to reveal how the Thwaites Glacier Ice Tongue in West Antarctica is being damaged by squeezing and stretching as it flows from the middle of the continent to the coast. Being able to track fractures and crevasses in the ice beneath the overlying snow is key to better predicting the fate of floating ice tongues under climate change.
