100 Years of Tutankhamun: Discovering the valley of the kings with radar
16 February 2023
100 years ago, British archaeologist Howard Carter opened Tutankhamun's burial chamber. For years he had been searching for the pharaoh's tomb in the Valley of the Kings, northwest of the Upper Egyptian city of Luxor. Almost giving up, he found Tutankhamun's tomb in the winter of 1922. However, several months of careful preparations were needed before the archaeologist could penetrate the interior of the burial chamber. On February 16, 1923, Howard Carter and his team finally broke through the door between the antechamber and the burial chamber. Inside, they found a treasure trove of almost completely preserved burial objects and the sarcophagus of the pharaoh - still a sensational find today

PermaSAR - DLR research in the Canadian Arctic
15 February 2023
Permafrost - the foundation of the Arctic and Antarctic - is changing drastically. DLR researchers can use radar to determine exactly which ice layers freeze and thaw and when. This is important in order to better understand the interplay with climate change and to be able to derive recommendations for action. In the Canadian Arctic, DLR's PermaSAR project team tested novel radar technologies that allow us to see inside the permafrost. The results will also serve future satellite missions for Earth observation, such as the Tandem-L mission proposal

Solar tower power plants - sunlight becomes electricity on demand
18 January 2023
Solar energy is becoming an increasingly important source of energy worldwide. In Germany, photovoltaic systems are currently predominantly in use. For sunny countries, solar tower power plants with integrated heat storage systems are also a valuable addition. They store heat and can thus generate electricity at any time - even when the sun is not shining. The new highlight images from the TerraSAR-X and TanDEM-X radar satellites present unique images of the Earth in transition and also show solar thermal power plants around the world.

DLR Magazin: Looking deep into the forest - A combination of remote sensing data provides new insights into the structure of forests
28 November 2022
Forests are gigantic carbon stores: Half of the carbon bound on earth is stored in them. They also control the transport of water and carbon dioxide between the soil and the atmosphere. Accordingly their role in mitigating climate change. However, changes in temperature and precipitation and worsening weather extremes pose a major threat to forests and their function. Therefore, it is important to know the condition of the Earth's forests and how their structure is changing. To investigate this, DLR scientists combined data from remote sensing missions. But that's not all: a future satellite mission could depict forest structure and how it changes over time in unprecedented quality.

Press Release: Radar measurements for efficient agriculture
07 June 2022
Droughts and dry spells are increasingly threatening arable farming. In Europe, this particularly affects the Mediterranean region with its important fruit, vegetable and cereal areas. In order to continue to safeguard harvests in the face of global climate change, the water supply must be adapted. One important factor is soil moisture. The German Aerospace Center (DLR) is testing new radar technologies that should make it possible to map moisture distribution in plants and the top layers of soil so that targeted measures can be taken. Together with the Italian Institute for Electromagnetic Environmental Sensors IREA, the researchers conducted the first of two multi-day test campaigns in Italy in April 2022. The second campaign will take place from June 14 to 17, 2022. The data collected will be used to apply and test procedures for deriving the "soil moisture" information product with respect to current as well as future European radar satellite missions. The distribution of soil moisture in the mapped region is shown geographically in the form of a map. The results of the measurement campaigns are of particular importance for the
radar satellite mission Tandem‑L
, which in the future could take a global look at soil moisture in addition to other climate variables.

Shipwreck of the 'Endurance' found – safe navigation thanks to satellite data
11 March 2022
Over a century ago, Ernest Shackleton's ship Endurance sank in Antarctica, trapped and crushed by the ice. The crew survived and the incredible rescue operation made the polar explorer's expedition legendary. The wreck has now been located with the support of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). DLR provided TerraSAR-X satellite images that enabled safe navigation through the ice-covered Weddell Sea. DLR researchers on board the expedition’s ship also studied the properties of sea ice to improve navigation in polar regions.

Ice-ocean interactions are accelerating melting in West Antarctica
11 March 2022
An analysis of Antarctica’s Pope, Smith and Kohler glaciers by researchers at the University of California, Irvine, NASA’s Jet Propulsion Laboratory, the University of Houston and other institutions has revealed an aggressive pattern of retreat connected to high melt rates of floating ice in the Amundsen Sea Embayment sector of West Antarctica.
In a paper published recently in Nature Geoscience, the team reports that the grounding line — where ice moves off the land and begins to float — of Pope Glacier retreated 3.5 kilometers in 3.6 months for an average of nearly 12 kilometers per year in 2017. Between 2016 and 2018, the western portion of Smith Glacier retreated at 2 kilometers per year and Kohler Glacier at 1.3 kilometers per year.

Satellites for Earth remote sensing – helpers in times of climate change
07 March 2022
IN GERMAN: Der neue Bericht des Weltklimarates (Intergovernmental Panel on Climate Change, IPCC) macht es deutlicher denn je: Die Weltgemeinschaft muss jetzt handeln! Wenn nicht geeignete Maßnahmen für den Klimaschutz und die Anpassung an den Klimawandel ergriffen werden, dann schließe sich das Fenster der Gelegenheit, eine lebenswerte und nachhaltige Zukunft für alle zu sichern. Bereits jetzt seien mehr als 3,3 Milliarden Menschen in hohem Maße von den Auswirkungen des Klimawandels wie Dürren, Hitzewellen oder Überschwemmungen betroffen, heißt es in dem Bericht. Um die biologische Vielfalt zu erhalten, müssten zwischen 30 bis 50 Prozent der Ökosysteme – Land-, Süßwasser- und Meeresflächen – geschützt werden. Nur so könnten sich diese an die veränderten Bedingungen anpassen.

DLR Magazin: On the traces of time
31 January 2022
IN GERMAN: Mit dem Start des Radarsatelliten TanDEM-X begann im Jahr 2010 eine neue Ära in der Radarfernerkundung. Seitdem umkreist er im engen Formationsflug mit seinem drei Jahre älteren „Zwilling“ TerraSAR-X die Erde. Zusammen liefern die beiden Satelliten Daten für Höhenmodelle der ganzen Welt. Diese stellen eine unentbehrliche Grundlage für kommerzielle Anwendungen und wissenschaftliche Fragestellungen dar, denn bis dahin existierten für weite Teile der Erde nur grobe, uneinheitliche oder lückenhafte Höhenmodelle unterschiedlicher Datenquellen und Erhebungsmethoden. Die Mission TanDEM-X änderte dies mit ihrem Digital Elevation Model (DEM), einem digitalen Höhenmodell der gesamten Landoberfläche der Erde in einheitlicher Qualität und bislang unerreichter Genauigkeit. Das ist den DLR-Wissenschaftlerinnen und -Wissenschaftlern aber noch nicht genug.

Glaciers are melting much faster than expected
28 January 2022
IN GERMAN: Der Südpol hat neue Sorgenkinder. Eine Gruppe von kleineren Gletschern schmilzt schneller als erwartet: Pope, Smith und Kohler. Bisher standen die benachbarten Eisgiganten Thwaites und Pine Island im Fokus der Forschung, da sie sehr fragil sind und den globalen Meeresspiegel um bis zu 1,2 Meter ansteigen lassen könnten. Das Deutsche Zentrum für Luft- und Raumfahrt (DLR) hat die Veränderungen in der Westantarktis gemeinsam mit internationalen Forschungspartnern aufgedeckt und analysiert. Den Ursachen für die rapiden Abschmelzungen der kleineren Gletscher kamen sie mithilfe spezieller Radardaten der Satellitenmissionen
TanDEM-X
und COSMO-SkyMed auf die Spur.
Die gewonnenen Erkenntnisse sind wichtig, um Gletscherprozesse besser zu verstehen und so die Entwicklung der gesamten Antarktis vorherzusagen. Klimaforschende können dann künftig noch genauer berechnen, wie stark der Meeresspiegel ansteigen wird und welche Schutzmaßnahmen am wirkungsvollsten sind. Die neue Studie ist aktuell im Fachjournal
Nature Geoscience
veröffentlicht. Sie ist das Ergebnis einer Zusammenarbeit von der University of Houston, dem DLR-Institut für Hochfrequenztechnik und Radarsysteme, der University of California, der Université Grenoble Alpes sowie der italienischen Raumfahrtagentur ASI.

DLR Magazin - New eyes for looking upwards
26 October 2021
IN GERMAN: Der Nachthimmel gehört längst nicht nur den Sternen: Mehr und mehr Satelliten umkreisen permanent die Erde. Ein besonders prominentes Beispiel ist die Starlink-Flotteder Firma SpaceX, die im letzten Jahr als leuchtende Perlenkette für Aufmerksamkeit sorgte. Doch in welchem physischen Zustand sich die einzelnen Satelliten befinden, ist oft nicht bekannt. Die Zustandsdaten der künstlichen Erdtrabanten sagen nichts darüber aus, ob ein Stück vom Solarpanel abgebrochen ist oder ein Brocken Weltraumschrott ein Loch in den Satellitenbus geschlagen hat. Häufig erfahren die Betreiberfirmen erst, dass der Satellit defekt ist, wenn Subsysteme ausfallen. Um den Zustand der Weltraumobjekte dauerhaft dokumentieren zu können und Ausfälle früh festzustellen, entwickeln DLR-Forscherinnen und -Forscher ein neues Konzept, das aus vielen Sender- und Empfängereinheiten aufgebaut ist und solche Himmelskörper dauerhaft mit höchster Qualität beobachten soll.

RADIAN interprets satellite images soon with KI
26 July 2021
IN GERMAN: The analysis of radar images is a demanding task: Image effects such as geometric distortions or image noise make interpretation difficult. To make this as intuitive as possible, scientists at the German Aerospace Center (DLR) have established the image analysis tool RADIAN (RAdar IMage ANalysis). RADIAN has been in use for more than ten years and is constantly being further developed. Now the focus is on automated information retrieval. To this end, an artificial intelligence (AI) is to learn to recognize changes in objects on the basis of existing data records. Such objects include aircraft, ships, vehicles, containers and buildings.

Using principles from painting – creating 3D-effect satellite images in true colour
29 March 2021
How can an impression of three-dimensionality be created using a two-dimensional medium? In art, this question arose centuries ago. Certain painting techniques have since evolved to simulate effects of light and shadow, creating a 3D effect for the viewer. Such effects are referred to as trompe-l'œil – they 'deceive the eye'.

Global Change: The Earth System
18. January 2021
‘Global change’ is not a recently invented term – it has been used since the 1980s to describe changes in the Earth system driven or triggered by human activities. In contrast to climate change, which only deals with one specific issue, global change takes into account a larger range of processes. For many years, DLR has been researching global change with a wide variety of missions. It develops archiving and processing technologies, devises algorithms for extracting relevant parameters from EO data and analyses the results.

Season´s Greetings and wishes from TanDEM-X!
22. Dezember 2020
Our Christmas star (
Download [11 MB]
) this year comes from Italy and was observed by the TanDEM-X satellite mission. The municipality of Palmanova, a UNESCO World Heritage Site, is located in the Veneto region. It was laid out at the end of the 16th century as a fortified city of the Republic of Venice, and its star-shaped layout followed the concept of Renaissance city planners for an ideal city. In this TanDEM-X image, the surface elevation is shown in colors (dark blue is 12 m and red is 38 m above mean sea level), while the brightness is proportional to the radar backscatter intensity. TanDEM-X was launched in 2010 and has been operating since then together with its twin TerraSAR-X as a bistatic SAR interferometer. This year we are commenmorating 10 years of TanDEM-X operations in close formation flight. The global digital elevation model (DEM) of TanDEM-X has been available since 2016 for commercial and scientific applications. A new edition of this global dataset, denoted as Change DEM, will be available soon. Look out for further news on TanDEM-X on

On to new heights - 10 years of TanDEM-X
20 December 2020
IN GERMAN: Seit Dezember 2010 bilden die Zwillingssatelliten TerraSAR-X und TanDEM-X, die im engen Formationsflug um die Erde kreisen, ein einzigartiges Radarinterferometer. Was bis 2010 nur in 2D erfassbar war (Bildteil in Schwarz-Weiß), gewann mit dem Satelliten TanDEM-X eine Dimension dazu. Zu sehen ist das Lenadelta in Russland. Der Fluss mündet hier nach 4.294 Kilometern in die Laptewsee, ein Randmeer des Arktischen Ozeans. Die etwa 1.500 kleinen Inseln im Delta ändern permanent ihre Form, weil das mitgeführte Material sich als Sediment ablagert und das Wasser umlenkt. In einem Atlas wäre das gesamte Gebiet nur in einer Höhe dargestellt. TanDEM-X sieht die Unterschiede viel differenzierter – mit einer Genauigkeit, die zwei Meter Auflösung noch übertrifft. Bereits 2016 erstellten DLR-Wissenschaftlerinnen und -Wissenschaftler ein exaktes 3D-Höhenmodell der gesamten Erdoberfläche aus den Daten der Mission TanDEM-X. Seitdem sammeln die Zwillingssatelliten Daten für ein zweites globales Höhenmodell. Das soge-nannte Change DEM (Digital Elevation Model) dokumentiert Veränderungen der Erdoberfläche in drei Dimensionen. Erste Auswertungen zeigen dramatische Entwicklungen wie das Abschmelzen von Gletschern und Eisschilden oder die ungehemmte Abholzung tropischer Wälder.

Glacial retreat in the Alps – first comprehensive documentation
08 July 2020
A research team from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) conducted the first study of area and elevation changes for all Alpine glaciers over a period of 14 years. This involved comparing three-dimensional terrain models obtained from the German radar satellite mission TanDEM-X and the German-US Shuttle Radar Topography Mission (SRTM) between 2000 and 2014. The team combined the elevation models with optical images from NASA’s Landsat satellites. They found that the Alps have lost approximately 17 percent of their total ice volume since the turn of the millennium. The team recently published the results of their study in the journal Nature Communications.

Congratulations, TanDEM-X – 10 years of 3D mapping from space
25 June 2020
A new era in radar remote sensing began 10 years ago, on 21 June 2010, when the radar satellite TanDEM-X was launched. Since then, it has been orbiting Earth in close formation flight with TerraSAR-X, its three-year-older 'twin'. The distance between the satellites varies between several kilometres and sometimes only 120 metres. This enables the radar sensors to obtain a 3D view of Earth. This is referred to as a bistatic interferometer in space, which allows the terrain structure to be recorded in three dimensions in just one pass. This space mission continues to be globally unique.

50 Years "Earth Day" - Satellites observe dramatic changes on Earth
21 April 2020
IN GERMAN: Millionen Menschen gingen am 22. April 1970 - heute vor 50 Jahren - in den USA auf die Straßen, um gegen Ölpest, Umweltverschmutzung, Walfang und Giftmüll zu demonstrieren - und sie begründeten damit eine Initiative, die schon bald den gesamten Globus erfassen sollte: Die Umweltbewegung, an die der heutige "Earth-Day" erinnert, hat unsere Zivilisation geprägt - vielfach mit wesentlichen Erkenntnissen aus dem Weltraum. In Corona-Zeiten lautet auch hier die Devise #EarthDayAtHome - unter diesem Hashtag sind beispielhaft Aktionen und Informationen zusammengestellt, die wir von zu Hause aus tun können, um unser Bewusstsein für die Verletzlichkeit und Einzigartigkeit unseres blauen Planeten zu schärfen. Deutschland ist seit dem Start des ersten deutschen Forschungssatelliten AZUR im November 1969 zu einem der weltweit wichtigsten Partner für die friedliche Erforschung der Erde aus dem All geworden. Das Deutsche Zentrum für Luft- und Raumfahrt (DLR) spielte und spielt hier eine Schlüsselrolle mit eigenen Missionen wie dem deutschen Radarsatelliten-Zwillingspaar TerraSAR-X und TanDEM-X und ab 2021 der EnMAP-Mission sowie den deutschen Beiträgen an ESA-Erdbeobachtungssatelliten wie dem ersten europäischen Wettersatelliten Meteosat in den 1970-er Jahren, gefolgt von ERS und Envisat bis hin zum aktuellen europäischen Satellitennetzwerk des Copernicus-Programmes.

25th Anniversary of the Space Shuttle Missions SIR-C/X-SAR
07 October 2019
Earth observers like to 'look' at the Earth with radar sensor systems. They allow high-precision images of the surface and have a great advantage over optical cameras: images can be taken not only in excellent visibility, but also in cloudy conditions, rain or at night. Research into space-based radar technologies has a long history. A milestone was the multi-frequency radar system SIR-C/X-SAR. 25 years ago, the Space Shuttle Endeavour flew around the world twice, in April and October 1994. It was the most advanced civil radar in Earth orbit at that time – and for Earth observation it was as big a step as the transition from black-and-white to colour film in photography.

TanDEM-X Earth observation mission: Tidal glaciers in Greenland – TanDEM-X elevation models show strongest decline in 80 years
13 September 2019
The Kangerlussuaq Glacier is the largest glacier on the southeast coast of Greenland and flows into the fjord of the same name. The glacier front, which in the past was protected by an ice mélange – a mixture of sea ice and calved icebergs – is retreating at an increasing rate. The glacier calves approximately 24 cubic kilometres of ice into the ocean every year. This corresponds to about five percent of the amount of ice lost annually by the entire Greenland ice sheet. Using a time series of 150 TanDEM-X elevation models of the Kangerlugssuaq Glacier, scientists from Swansea University in the United Kingdom have measured the decrease in the glacier’s surface height.

South America: TanDEM-X reveals glaciers in detail
12 June 2019
A precise understanding of glacier evolution requires knowledge of a glacier's exact mass. This is important in South America, in the tropical regions between Bolivia and Venezuela, where meltwater from glaciers provides drinking water during the dry season. However, basic data about mass changes in glaciers are not easy to obtain. Mass losses are also contributing to rising sea levels on a global scale. As a new analysis method using TanDEM-X data shows, this is particularly true for Patagonia.

Global TanDEM-X forest map is available
06 May 2019
Forests are Earth's lungs; they help to reduce greenhouse gas concentrations in the atmosphere and thus counteract global warming, while also providing protection and resources for humans, animals and plants – and they are being lost at an alarming rate. As the view from space reveals, forests cover about one third of Earth’s landmass today. More than half of the world’s forests, which have fallen victim to deforestation since the middle of the 20th century in particular, have already been lost. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), Microwaves and Radar Institute (HR) has created a special dataset to monitor, assess, and protect the current state and development of this green organ with precision – the global TanDEM-X Forest/Non-Forest Map.

Season´s Greetings and wishes from TanDEM-X!
23 December 2018
All people living in the world today are descended from Africans who left the continent at least 100,000 years ago. Those who stayed behind continued to innovate and develop their knowledge and ideas. The TanDEM-X image above shows the topography of Cape Town and its surroundings.
Table Mountain
, a well-known landmark of the city, is seen just south of the harbor area. The Cape Town region is characterized by an extensive coastline, rugged mountain ranges, coastal plains, inland valleys and semi-desert fringes. TanDEM-X was launched in 2010 and has been operating together with its twin TerraSAR-X as a bistatic SAR interferometer since the beginning of 2011. The global digital elevation model of TanDEM-X became available in 2016 and surpassed all expectations. It has 99.9% coverage, 12-m posting, absolute height accuracy of approximately 1 m. This unique data set has been available since then for commercial and scientific applications. This year, the low-resolution version of the TanDEM-X digital elevation model with 90-m posting has been released for free download for scientific applications.

IN GERMAN: Wir haben in den letzten Tagen viel in den Medien über den riesigen Eisberg lesen können, der sich am Larsen-C-Schelfeis an der Antarktischen Halbinsel gelöst hat. Dass Eisbergabbrüche von Eisschelfen natürliche Vorkommnisse sind und diese in der Antarktis immer wieder vorkommen, wurde in den Medienberichten richtig dargestellt. Und doch war dieses Ereignis präsenter als die bisherigen. Woran liegt das? Vermutlich daran, dass wir Wissenschaftler seit Monaten mithilfe von Satellitendaten dieses Gebiet der Antarktis verstärkt beobachten und regelrecht darauf gewartet haben, dass es endlich passiert. Außerdem ist diesmal doch ein verhältnismäßig großes Stück Eis abgebrochen, ungefähr sieben Mal so groß wie die Stadt Berlin.

Faster detection of landmines using radar
22 February 2016
Every 20 to 30 minutes, somewhere in the world, a person – often a child – steps on a landmine. It is estimated that over 100 million anti-personnel mines are buried worldwide and a further 200 to 250 million are thought to remain in military storage facilities. This means they pose a constant threat, even long after the end of a conflict. In order to facilitate the reconstruction of a country and the safe return of refugees, the ground must be cleared of concealed ordnance. The German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) has developed a radar-based method, 'TIRAMI-SAR', that will allow for the quick, safe and cost-effective detection of landmines.

Ten Sentinel-1A radar scans acquired between 7 October 2014 and 12 March 2015 were combined to create this image of ground deformation around the city of Naples, which includes the active volcanic areas of Italy’s Phlegraean Fields – or Campi Flegrei – and the Vesuvius volcano. Dark blue indicates areas that experienced an uplift of about 0.5 cm per month, while red areas show subsidence down to 0.5 per month. The purple square over the city of Naples indicates the location of the calibration point. These preliminary results are presently presented at the Fringe Workshop at ESA’s ESRIN centre for Earth observation.

Data Transmission via LTE
18 March 2015
So far, in the VABENE++ project data gets transmitted from the aircraft/helicopter to the ground via a special microwave link or an optical laser link. However, for these data links a special mobile ground station needs to be set up in the field. Now a study was carried out to investigate whether the modern mobile communication standard “Long Term Evolution” (LTE) can be used as an alternative or supplementary data transfer technique. For data reception on the ground only the already available LTE ground station infrastructure of the cellphone providers was considered.

Fastest glacier in Greenland – DLR satellites TerraSAR-X and TanDEM-X identify speed record
04 February 2014
Since the 1990s, Jakobshavn Isbræ has been regarded as the fastest moving glacier in Greenland. According to studies carried out by researchers from the University of Washington and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), its speed is now increasing dramatically, with record figures for 2012 and 2013. High spatial and temporal resolution data acquired by the German radar satellites TerraSAR-X and TanDEM-X enabled very precise calculations of its speed. The results of the study will be released in the print version of 'The Cryosphere', an international scientific journal of the European Geosciences Union (EGU), on 7 February 2014.

TerraSAR-X image of the month – Coral Atoll Kiritimati
16 Dezember 2013
AVAILABLE IN GERMAN: Paris ist verlassen, in Polen leben 235 Menschen, und London hat immerhin 1829 Einwohner. Auf dem Atoll Kiritimati ist vieles anders - und so werden aus europäischen Großstädten oder Ländern winzige Orte. Der abgelegenen Insel im Pazifik, auf der Seefahrer James Cook mit seiner Mannschaft 1777 Weihnachten feierte, steht das Wasser buchstäblich bis zum Hals. Das Korallen-Atoll hat zwar 321 Quadratkilometer Landfläche - aber auch 324 Quadratkilometer Lagunenfläche. Treffen die bisherigen Schätzungen zu, könnte der Inselstaat Kiribati mitsamt der Insel Kiritimati etwa im Jahr 2070 aufgrund des Klimawandels und des Anstiegs des Meeresspiegels im Pazifik versinken. Für den Radarsatelliten TerraSAR-X des Deutschen Zentrums für Luft- und Raumfahrt (DLR) sieht das Atoll aus über 500 Kilometern Höhe wie eine poröse, zerbrechliche Struktur aus.

EUSAR 2014 - Organized by DLR’s Microwaves and Radar Institute
The 10th European Conference on Synthetic Aperture Radar (EUSAR) is being organized by DLR’s Microwaves and Radar Institute in the heart of Berlin. Traditionally, EUSAR's organization rotates among the four founding organizations: Fraunhofer (FHR), EADS Astrium, EADS Cassidian and DLR (HR). After EUSAR 2000 in Munich and EUSAR 2006 in Dresden we choose Berlin (Hotel Maritim at Tiergarten near Brandenburg Gate) as venue for EUSAR 2014. Over the years EUSAR has developed to the world's most renowned conference in the field of Synthetic Aperture Radar (SAR). Despite the difficult situation of travel fund shortages in traditionally strongly represented countries we received more than 400 papers for EUSAR 2014. More than 1200 reviews have been assigned and have been nearly finished by more than 150 SAR-experts from all over the world. We will soon be able to create a first, preliminary EUSAR 2014 Program and would like to thank all our reviewers for spending their precious time and support to make EUSAR 2014 a success.

Wide-angle view from space
30 August 2013
Officially, the German radar satellite TerraSAR-X should have been out of service for over a year and a half – that's how long it has exceeded its intended lifespan. But engineers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have switched the satellite, which was launched to space on 15 June 2007, to yet another mode: TerraSAR-X can now record image strips over 200 kilometres wide. "The satellite does so by sweeping this large area in multiple stages, very quickly pivoting the radar beam numerous times across the direction of flight," explains DLR mission manager Stefan Buckreuss. For example, the image of the German Bight shows the Frisian Islands from Borkum to Wangerooge and cities such as Wilhelmshaven and Bremen. This new ‘wide-angle’ mode is of particular interest to oceanographers, who will be able to use it to investigate the tidal range, changes to mudflats, shipping movements, wave patterns, ice floes and wind levels.

Longest glacier in Antarctica has 'calved'
09 July 2013
Ice researchers use data from the DLR-operated TerraSAR-X Earth observation satellite: Two gigantic cracks have formed in Pine Island Glacier, the longest and fastest-flowing glacier in the Antarctic. A new iceberg with an area of over 720 square kilometres and its smaller 'brother' separated from the glacier on 8 July 2013 and have 'calved' into the Amundsen Sea, off the west coast of Antarctica. Images acquired by the TerraSAR-X Earth observation satellite, operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), documented the gradual propagation of the first crack over a period of several months. On 11 May 2012, a second crack was discovered. Glaciologists can use this data to better understand the processes involved in the calving of icebergs.

TerraSAR-X image of the month – the coastal cliffs of Christmas Island
07 January 2013
Captain William Mynors was not particularly creative as he sailed past a remote island in the Indian Ocean on the 'Royal Mary', a ship belonging to the British East India Company, on 25 December 1643. He named the 135-square-kilometre island, which he could not even disembark on, 'Christmas Island'. In the image acquired with the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) TerraSAR-X radar satellite, one thing is clear – even today, tropical rainforest proliferates on the island and the coastal cliffs continue to make life difficult for mariners.

TerraSAR-X image of the month – the Santorini volcano expands
23 November 2012
Glasses are rattling on the shelves and the ground is rumbling – since January 2011 the earth under the Santorini volcano has been stirring. Most of the time, it is barely noticeable, but every now and then the inhabitants notice small tremors jolting the volcanic archipelago. Nearly circular, and seemingly carved from stone, the submerged caldera is located in the Aegean Sea. "It was clear to the local people that something was happening with the volcano – but it wasn't until we saw, among other things, the images from the TerraSAR-X radar satellite that we realised that molten rock was pooling beneath the volcano," says British scientist Juliet Biggs from the University of Bristol. Images acquired by the German Aerospace Center's (Deutsches Zentrum für Luft- und Raumfahrt; DLR) satellite show the entire archipelago not just rising, but also expanding.

TerraSAR-X image of the month – stage clear for the salt flats
19 October 2012
The Bonneville Salt Flats is the largest salt pan lying to the west of the Great Salt Lake, in the northern part of the US state of Utah. The salt pan arose towards the end of the last ice age as a consequence of Lake Bonneville drying up. This was a prehistoric lake that stretched across a large section of the major basin to the west of the Rocky Mountains, and of which only the Great Salt Lake now remains. The former Bonneville Lake is history; today the salt flats stretch out over an area of some 10,360 square kilometres.

TerraSAR-X image of the month – Lively winter view
02 March 2012
Ice and snow can be colourful – at least when seen through the 'eyes' of the German Aerospace Center's (Deutsches Zentrum für Luft- und Raumfahrt - DLR) TerraSAR-X radar satellite. The radar signals are able to penetrate the snow cover to a depth of one metre – and the subsurface reflects the pulse in different ways. This makes the frozen delta of the Mackenzie River in Canada appear multi-coloured in an image revealing the various structures in the landscape underneath the snow.

TerraSAR-X image of the month: Forest imaging in Gabon for the United Nations
30 November 2010
In Gabon, West Africa, the forest cover spans 210,000 square kilometres, or 70 percent of the total land area. It is hard for field researchers to get an overview of the situation and the frequent cloud cover in the tropics hinders observations from the air. Researchers at the Friedrich Schiller University of Jena are studying images acquired by ther German Aerospace Center's (DLR) TerraSAR-X radar satellite, as part of their contribution to the United Nations' Global Forest Resources Assessment. The satellite's radar imaging is unaffected by cloud cover or the time of day.

TanDEM-X helps mapping Pakistan floodings
06 August 2010
Satellite data is an indispensable tool for quickly assessment of the situation in cases of natural or environmental disasters and for guiding emergency teams on ground. DLR's 'Center for Satellite Based Crisis Information' (Zentrum für satellitengestützte Kriseninformation; ZKI) and many other international organizations have been using the German radar satellite TerraSAR-X for three years to rapidly obtain reliable data in all weather conditions for such crisis situations. Now, our new satellite, TanDEM-X, has also provided assistance for the first time in a crisis – gathering information on the flood catastrophe in Pakistan. We were able to help not only with radar images but we also used TanDEM-X for interferometry in formation with TerraSAR-X for the first time. This has provided a more reliable technique to map floods instantaneously and more accurately, in one pass and without the need for archived data.

The German Earth Observation Satellite TerraSAR-X - Successfully in Operation Since Two Years
15 June 2009
TerraSAR-X, Germany's Earth observation satellite, was launched on 15 June 2007 and has gone on to have a unique and highly successful track record. In contrast to optical systems, the radar technology on this satellite enables it to record images through cloud and at night, meaning that it is able to operate continuously, right around the clock. TerraSAR-X is Germany's first radar satellite and is, at the same time, the first nationally operated remote sensing satellite, brought into being by a Public Private Partnership (PPP) between the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and Friedrichshafen-based Astrium GmbH. DLR is responsible for planning and carrying out the mission, for controlling the satellite and the radar instrument, and for the scientific use of TerraSAR-X data.

German TanDEM-X radar satellite now complete
9 June 2009
In early 2009, Friedrichshafen-based aerospace company Astrium completed construction of the German radar satellite TanDEM-X. This satellite was created in collaboration with the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). The satellite, five metres in length and weighing 1.3 tons, has now been transported to Ottobrunn, a town near Munich. In special-purpose test facilities operated by Astrium and IABG (an industrial equipment operating company), the satellite will undergo trials until mid-September 2009 to confirm its suitability for operation in outer space. It will be subjected to extreme temperatures and radiation and, in particular, the loads experienced during launch will be simulated. Once the tests are completed, the satellite will be transported to the Baikonur Cosmodrome in Kazakhstan.

TerraSAR-X Image of the Month April 2009: The Wadden Sea in North Frisia
21 April 2009
The image shows the mudflats near the island of Sylt. It was compiled from two satellite images that were taken by the German radar satellite TerraSAR-X in April and May 2008. The individual pictures are coloured red and green respectively. The difference in the reflected radar signals is especially large over the areas of water, as it is here that there were the most changes between when the first picture was taken in April and the second in May. The blue coloured strip has been used to highlight this. The resulting image can be used to extensively study the morphology, sediments and habitats in the Wadden Sea.

E-SAR aquires P-Band Data over Boreal Forest in Northern Sweden
20 October 2008
How best to map ‘boreal’ or northern forest with spaceborne radar is the focus of an ESA campaign currently underway in northern Sweden: BioSAR. The BioSAR 2008 campaign represents the first-ever ESA airborne Synthetic Aperture Radar (SAR) campaign over northern boreal forest. DLR-HR's E-SAR system acquires P-band data for this purpose. Because of the importance of boreal forests for ESA's BIOMASS mission, and the global carbon cycle in general, highly accurate and robust methods for transforming the P-band radar signals into forest biomass maps are required.

SAR-Lupe, Germany’s First Satellite-Based Reconnaissance System, Now Completed
22 July 2008
This morning, the fifth German reconnaissance satellite of the SAR-Lupe system was launched successfully from the Russian Plesetsk Cosmodrome south of Archangelsk. The Russian Cosmos-3M launch vehicle took off according to schedule at 4.40 Central European Summer Time (CEST) and about half an hour later released the radar satellite into its low Earth orbit, about 500 kilometres from the ground. The first communication between the German Space Operations Center (Deutsches Raumfahrt-Kontrollzentrum) of the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) in Oberpfaffenhofen and the satellite showed that the satellite is functioning faultlessly. DLR has already started to put the satellite into operation.
