How many electric cars will be using Germany's roads in 2020? None of us have a crystal ball and this will depend on a wide variety of factors.
On 11 May 2011, the camera on board the Dawn spacecraft acquired its first picture of the asteroid Vesta. Despite its diameter of 530 kilometres, this heavenly body appeared as no more than a white dot in the image – at that time, the spacecraft was still 975,000 kilometres away from its destination.
The images presented in this mosaic and acquired with the High Resolution Stereo Camera (HRSC), on board ESA's Mars Express Spacecraft, show Becquerel Crater and, inside it, a mountain almost 1000 metres high, consisting of sulphurous layers deposited on top of one another. It demonstrates the eventful climatic history of the Red Planet.
These images, which were acquired using the High Resolution Stereo Camera (HRSC) operated by the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR) on board ESA's Mars Express spacecraft, show a section of the northern part of Hesperia Planum.
On 21 January 2013, the HRSC camera, operated by DLR on board ESA's Mars Express spacecraft, imaged the southeast portion of the Olympus Mons shield volcano, the largest volcano in the Solar System, located approximately 200 kilometers southwest of the Sulci Gordii region.
Numerous dramatic flood events sculpted the impressive valley system of Kasei Valles on Mars, seen in a new mosaic of 67 individual images acquired by the High Resolution Stereo Camera (HRSC) operated by DLR on board ESA's Mars Express spacecraft.
Nobody would have believed it back then; when the European Space Agency (ESA) spacecraft Mars Express was launched on 2 June 2003 to investigate our neighbouring planet, its mission was intended to last one Mars year, which is equivalent to about two Earth years.
Grabens, dendritic valleys, lava flows and the highest known mountain in the Solar System – in the images from the German stereo camera on board the Mars Express spacecraft, the topography of the Red Planet appears so three-dimensional that you could walk through it.
Huge landslides, lava flows and tectonic forces have generated the stunning landscape seen in these images acquired by the DLR-operated HRSC camera system on board the Mars Express spacecraft.
Intense underground steam explosions that occurred during the crater formation process could be responsible for the central depressions present in these 'twin' craters, located on Thaumasia Planum, an elevated plateau that lies immediately to the south of Valles Marineris, the largest canyon in the Solar System.
