The lava outflow on the Holuhraun field northeast of Iceland's Bardarbunga volcano continues unabated. The lava field has grown to cover an area greater than 25 square kilometres.
The Bardarbunga volcano on Iceland began erupting on 31 August 2014 – an effusive eruption with no ejection of volcanic ash. However, measurements made by DLR have since indicated that there is ongoing emission of sulphur dioxide (SO2). High sulphur dioxide concentrations in the atmosphere are a clear indication of volcanic activity, as there are no other natural emission sources, only anthropogenic ones.
Bardarbunga, (Bárðarbunga) in Iceland, one of the largest volcanoes in Europe and located beneath the biggest glacier in Europe, became active again in mid-August. For several years now, DLR researchers have been keeping a close eye on Bardarbunga and the system of volcanoes associated with it – an enormous network of subterranean magma channels, vents and craters.
The radar system on board the European Space Agency (ESA) Sentinel-1A satellite has been imaging Earth's surface in 250-kilometre swathes since April 2014. Now, scientists at DLR, working under a contract from ESA, have created the first interferogram from this data – showing the topography of Earth as a coloured pattern.
The target field on the International Space Station (ISS) where the final European Automated Transfer Vehicle (ATV) cargo carrier, ATV-5 Georges Lemaître, recently docked is just 60 centimetres tall. The spacecraft arrived at 15:29:53 CEST on 12 August 2014, precisely manoeuvring automatically to arrive at the Station, at an altitude of around 400 kilometres. Astronaut Alexander Gerst had one primary task – to monitor the docking process and cancel the automated procedure in the event of an emergency. Inside the 20-ton craft are experiments such as the Electromagnetic Levitator (EML) and the DLR magnetic experiment MagVector/MFX, together with food, coffee and clothing for the astronauts, fuel, air and drinking water, as well as a replacement pump for the water treatment system in the Columbus research laboratory. Overall, the ATV-5 transported roughly 6.6 tons of cargo into space. The sophisticated unloading process now begins for the teams in the control rooms at the German Aerospace Center (DLR) in Oberpfaffenhofen and Cologne.
Following its textbook launch on 30 July 2014, the fifth and final supply spacecraft in the European Automated Transfer Vehicle (ATV) series is on its way to the International Space Station (ISS). The freighter – which is named after Belgian physicist Georges Lemaître, father of the Big Bang theory – is roughly the same size as a London double-decker bus and, together with its payload, weighs more than 20 tons. Scheduled to dock with the Space Station at 15:34 CEST on 12 August, it will supply the ISS with fuel, food and new experiments; it will remain attached to the Station for at least five months.
On 1 August 2014, the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) and Telespazio, a Finmeccanica/Thales company, reconfirmed their cooperation for the operation of the European satellite navigation programme Galileo.
Atmospheric gravity waves influence the weather and long-term, climate-related atmospheric processes. For a number of nights between 29 June and 23 July 2014, the DLR Falcon research aircraft will be flying over the New Zealand Alps (Southern Alps) to investigate how these waves propagate from Earth's surface up to an altitude of around 100 kilometres using modern laser metrology and other instruments.
The sometimes bold, other times delicate lines in the images that scientists from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) have created using data acquired by the German radar satellites TerraSAR-X and TanDEM-X resemble Chinese ink drawings.
Alexander Gerst has been living and working in microgravity since 29 May 2014, and the focus of his initial research on the International Space Station (ISS) is currently himself.
