What kind of mysteries and scientific intrigue await the European Space Agencys Venus Express once it has left Earth for its nearest planetary neighbour in 2005? A closer inspection promises to reveal a planet that is hugely different from our own despite a few similarities.
Astronomers often call Venus the Earths twin because both are about the same size and have the same mass. In other ways, however, Venus seems to be an altogether different class of planet. Scientists are keen to take a closer look at this cloudy, mysterious planet. After a 150-day cruise from Earth, Venus Express will manoeuvre into an orbit that loops over the poles of the planet once every 10 -16 hours. What will we see?
The first of many curiosities is the nature of the Venusian magnetic field. It is so weak that particles ejected from the Sun, known as the solar wind, do not go around the planet, as they do at Earth. Instead they continuously strike Venuss upper atmosphere. Scientists want to know more about how this process takes place.

On January 15, 2009, Chesley B. Sullenberger was celebrated world-wide: after the two engines had failed due to bird strike, he and his flight crew succeeded after a glide flight with an Airbus A320 in ditching on the Hudson River. All 155 people on board were saved.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...
