TerraSar-X
A new satellite image that shows the likely spread of oil from the Rena suggests things may be worse than many realise.
The satellite image was captured by DLR, the German Aerospace Centre, by its TerraSAR satellite on Friday and shows the likely spread of oil from the ship, which remains stuck on the Astrolabe Reef off the coast of Tauranga.
The ship has spilled more than 350 tonnes of oil since it struck the reef on October 5 and is expected to leak more with rough weather predicted later today.
The crater of the Chilean volcano Puyehue displays a striking, circular outline in this image from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) TerraSAR-X satellite – so this was not the culprit when a volcano in the southern Andes erupted on 4 June 2011. Instead, as the images from the German radar satellite show for the first time, the new eruption centre lies 6.7 kilometres further to the northwest, in the Cordón Caulle region. A field of lava, appearing as a uniform, light blue surface, is currently forming there.
The first satellite image of the Ukrainian site was acquired by SPOT1 only ten days after the explosion demonstrating the value of Earth-imaging satellites in responding to natural and man-made disasters
Technology has evolved in the 25 years since the Chernobyl explosion and Astrium GEO-Information’s satellites continue to keep a watchful eye on the zone.
After the severe earthquake and tsunami in Japan, the International Charter ‘Space and Major Disasters’ was activated on the morning of the 11 March 2011. All participating institutions were asked to provide satellite imagery of the affected area.
On 22 July 2010, researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) facility in Oberpfaffenhofen published the first 3D images from the TanDEM-X satellite mission. Just one month after the launch of TanDEM-X (TerrraSAR-X add-on for Digital Elevation Measurement), which took place on 21 June 2010, DLR researchers have created the first digital elevation model – almost a week ahead of schedule. A group of Russian islands in the Arctic Ocean was selected for the first test.
The construction of the German radar satellite TanDEM-X (TerraSAR-X add-on for Digital Elevation Measurement) is complete and the satellite has been qualified for space operations during a series of tests conducted at IABG in Ottobrunn, near Munich. As with its 'twin' satellite TerraSAR-X, the TanDEM-X project has been implemented as a public-private partnership (PPP) between the German Aerospace Centre (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and Friedrichshafen-based Astrium GmbH.
Following the devastating earthquake on Haiti, relief organisations require rapid, reliable and meaningful information on the local situation, the state of the infrastructure and the extent of the damage for their deployment in the disaster zone. In this context, scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) are giving important support by providing free access to maps of the crisis region based on satellite data.
