Thunderclouds over rainforests are an important element in the climate system. The DLR research aircraft HALO spent the period from the beginning of September to the beginning of October 2014 in Manaus, a city in the Brazilian state of Amazonas, measuring the emergence, development and properties of tropical clouds.
Since the Icelandic volcano system of Bardarbunga began erupting, concerns about a volcanic ash cloud spreading across Europe and bringing air traffic to a standstill, as occurred in April 2010, have arisen once again. To enable the aviation industry to respond to volcanic ash more flexibly in the future, the German Aerospace Center (DLR) has been developing an improved satellite-supported volcanic ash detection system as part of Project VolcATS (Volcanic Ash Impact on the Air Transport System). DLR researchers are using improved views of the situation to investigate how air traffic management can adapt flexibly to large-scale airspace restrictions caused by volcanic ash
The 2014 harvest season is coming to an end, and throughout Germany the signs are of good yields for wheat, corn and similar crops. But the differences are large depending on the location. Hence, for optimum cultivation, it is important to be constantly aware of the condition of the soil and the crops. Radar images are particularly suitable for providing large-scale observations – using an aircraft or a satellite.
To support the safety of air transport and improve the air traffic system's response times in the critical event of a volcanic eruption, the identification of ash-free airspace is essential. At DLR, a satellite-supported procedure has been developed that rapidly determines the distribution of ash in the air and generates detailed images of areas with both heavy and light ash loads.
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.
