Most people think diesel engines are significant contributors to air pollution. But modern models produce hardly any particulates or nitrogen oxides. We spoke with Thomas Koch about a technology that has fallen into such disrepute.
Scientists are working to grow fresh vegetables in a greenhouse surrounded by perennial ice. The experiment will supply the winter crew at Neumayer Station with fresh food, but it is primarily designed to provide experience and data for future Mars missions.
Complex and expensive tests are necessary in order to develop aircraft. The subsequent maintenance is also very costly for the airlines. The German Aerospace Center (DLR) is seeking to change all this through the use of supercomputers and the evaluation of huge amounts of data.
The aim of the European Copernicus Project is to deliver high-resolution images of virtually every place on earth – none of them older than five days and as a complimentary service that is accessible to everyone. The launch of the Sentinel-2B satellite means that the core of the mission has now been completed.
The Planet Earth in 3D, and more precise than ever before! Research scientists create, with the aid of two satellites, a map of the world that has 30 times more precision.
Humans do not leave their trash only on land or in the oceans. In outer space as well, remnants of their accomplishments are to be found. Millions of small pieces of debris are orbiting our globe.
With a reproduction of Otto Lilienthal’s soaring apparatus, research scientists at DLR have been able to scientifically reconstruct the cause of the crash during his final flight.
A motorist’s dream could become reality: A smartphone app or the navigational device indicates where the next available parking space is located. Siemens is now testing, with a radar-supported sensor network, what is possible.
Actually, it is not out there somewhere among the innumerable heavenly bodies of outer space – the coldest place in the universe is right here in research laboratories on Earth.
Alois Himmes, project director at Stratosphere Observatory for Infrared Astronomy (SOFIA) and staff member at the German Aerospace Center (DLR) provides this answer.
