An international consortium of scientists, including transport researchers from the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), is examining the opportunities and risks of mega-cities and metropolitan areas. The primary research objective, based on the metropolis of Santiago de Chile, is to provide recommendations for strategic urban planning and to minimise problems such as traffic congestion and air pollution. Francisco Martínez, one of Chile’s leading transport researchers, summarises the results and reasons for cooperating with DLR in the following interview. Martínez is a professor at the Universidad de Chile, and his work focusses on transport systems, urban development and modelling raffic behaviour. In a video made by the Helmholtz Center for Environmental Research, one of the other partners on this project, Francisco Martínez and DLR transport researcher Andreas Justen review the situation in this South American metropolis.
By pressing a button, the driver determines the degree of automation. Road accidents often occur due to errors made by inattentive, tired or overworked drivers. The objective of the EU project HAVEit (Highly Automated Vehicles for Intelligent Transport), in which transport researchers at the German Aerospace Center (DLR) were involved, was to minimise the number of such accidents.

The Stratospheric Observatory for Infrared Astronomy (SOFIA) is a joint German-US space science project. Carrying a 2.5-metre telescope inside a modified Boeing 747SP, the airborne observatory performs astronomical observations in the infrared and submillimetre wavelengths, high above the disturbance of Earth's atmosphere.
For the first time, researchers from the German Aerospace Center have depicted Mount Everest, the 'Roof of the World', in 3D using optical satellite data at a maximum resolution of just half a metre. These 3D images are the outcome of a collaborative venture between the DLR Institute of Robotics and Mechatronics, the German company 3D RealityMaps GmbH and DigitalGlobe, one of the world’s leading providers of commercial, high-resolution Earth observation products. A video allows the viewer to follow the route taken by 15 mountaineers on a current expedition to the summit of the world’s highest mountain.
The dynamic component testing facility consists of two modular crash-test sleds, each up to two metres long and 1.3 metres in height. They stand on an 11.5-metre long rail track, so that the 'target' test sled can move backwards on impact. In the first test, DLR engineers accelerated a 1.5-metre long sled with a total mass of 1.3 tons to a maximum speed of 64 kilometres per hour. A compressed air cylinder powers the sled, and a hydraulic brake controls the acceleration.
This short DLR film shows how the region can be supplied with low-cost electricity from the desert.
The Automated Transfer Vehicle Johannes Kepler was launched on a specially modified launcher, the Ariane 5ES, at 22:50 CET on 16 February 2011 from Europe's spaceport in French Guiana. The second space cargo carrier in the Automated Transfer Vehicle (ATV) programme, it is now en route to the International Space Station (ISS).
The catapult in the tunnel simulation facility at DLR Göttingen accelerates models of high-speed trains to 400 kilometres per hour. The system can simulate, for example, the entry of high-speed trains into tunnels.

The Traffic Tower at Berlin Adlershof uses taxis as a congestion detector; with this data, DLR researchers are analysing the situation on the streets.

DLR researchers successfully demonstrate their work on a test track near Aachen. The novel RCAS anti-collision system uses direct train-to-train communication to alert the train operators in time to prevent a possible collision.

On the 130-metre long test range at DLR Lampoldshausen, laser beams will be precisely analysed under real environmental conditions. This video is part of DLR’s annual review from March 2010.
