Displacement of the iceberg at the Larsen-C ice shelf between July and October 2017

The A68 iceberg has been making headlines again after calving from the Larsen-C in July 2017. What happened? It moved and shrunk minimally. And while that may not be unusual, it is still worth a blog post.

Close examination of satellite image sequences from the last two months reveals the striking events unfolding there. Remember, the 5800 square kilometre iceberg is seven times the size of Berlin and is permanently moving. The iceberg has collided repeatedly with the ice shelf, dislodging smaller pieces of ice. read more

How researchers use the latest Earth observation data – Part two

In the second part of the series on the TerraSAR-X and TanDEM-X Science Meeting in Oberpfaffenhofen, we present further applications for satellite data. This time, for example, biomass is determined with the help of 'Earth observers from space'. Up until Thursday, 20 October 2016, international scientists will use the congress to show their research results on satellite-based Earth observation and to exchange ideas.

High above the swamp

Wet, warm and salty – the perfect habitat for mangroves. These tropical trees only feel at home in seawater or the brackish water of rivers. Together with other water-loving plants and shrubs, they can spread across entire forests or swamps. They offer protection against land loss through coastal erosion along seaboards and act as buffers to block storm surges and tsunamis. Around the world, mangrove forests account for an expanse of roughly 150,000 square kilometres. This equates to an enormous quantity of biomass – plant constituents that act as natural carbon reservoirs and that influence the climate. But exactly how much biomass is stored in these forests? And what about the inaccessible areas? read more

Researchers from across the globe are in Oberpfaffenhofen for the TerraSAR-X and TanDEM-X Science Meeting. For four days, from 17 to 20 October 2016, they have the opportunity to present their results from the data acquired by the two Earth observation satellite missions and exchange information. Here, approximately 200 presentations give an overview of the latest research in satellite-based Earth observation. The radar data are used in various scientific fields, from climate research to geosciences to forestry, infrastructure planning and remote sensing methodology.

Covering the Science Meeting, the Space Blog presents some of the work presented. The short examples provided outline how the data of the German radar satellites support researchers worldwide. read more

Formation swapping - Comic about the TanDEM-X mission

An exciting manoeuvre awaits us. In early August (6–8 August 2013), the two TanDEM-X mission satellites will be reversing their formation. Until now, the TanDEM-X satellite has been circling around its twin, TerraSAR-X, in an anti-clockwise direction; after the reversal, it will circle clockwise. read more

DLR Webcast: Interview with Marwan Younis at IGARSS 2012

DLR Webcast: Interview with Marwan Younis at IGARSS 2012

We are still here at IGARSS, giving you more information about 'Remote Sensing for a Dynamic Earth'. We spoke with Marwan Younis, who took some time from an incredibly tight schedule to answer some questions regarding TerraSAR-X and TanDEM-X, as well as Synthetic Aperture Radar (SAR) technologies. read more

Congratulations! DLR experts receive IEEE award

Congratulations! DLR experts receive IEEE award

DLR scientists had reason to celebrate one month ago – the successful TerraSAR-X mission celebrated its fifth anniversary in space. Today, on 23 July, during the Plenary Session at the International Geoscience and Remote Sensing Symposium (IGARSS 2012) in Munich, the hard work of DLR experts involved in the radar satellite TanDEM-X mission has been recognised. Our DLR colleagues were awarded with the ‘IEEE WRG Baker Paper Award’. This award is given annually to scientists who accomplish extraordinary achievements in the field of electrical engineering and computer science. read more

Observing Earth from space - IGARSS 2012

IGARSS 2012

The countdown to the International Geoscience and Remote Sensing Symposium IGARSS 2012, has begun - only 6 days remain. This year, IGARSS will be held at the International Congress Centre in Munich from 22-27 July, and with this blog, we will be reporting on all the breaking announcements and important events. We will do this with written entries, images and webcasts - in which specialists in Earth observation and remote sensing will join us. read more

Where and how does ice move in the ocean?

TanDEM-X has now begun routine operations, and is working with TerraSAR-X in bistatic mode and recording data for its global digital terrain model. In this post, I look back at an earlier phase of the mission, when this satellite pair orbited the Earth separated by a mere three seconds or 20 kilometres, and each sensor acquired images independently. read more
