ESA’s Huygens probe, now orbiting Saturn on board the NASA/ESA/ASI Cassini spacecraft, is in good health and successfully passed its fifteenth ‘In-Flight Checkout’ on 14 September 2004.
This in-flight checkout procedure was the last but one planned before separation of the Huygens probe from Cassini in December this year, and it included some specific activities that were intended to prepare for the separation. The main difference in this procedure from previous checkouts was that there was a test of the Master Timer Unit (MTU). Because Huygens will spend three weeks coasting towards Titan following separation from the Cassini orbiter, its systems and instruments are powered down.
The MTU is the ‘triple-redundant’ alarm-clock that has the most important job of waking up Huygens a few hours before its entry into Titan’s atmosphere. The checkout also included some specific payload activities required to configure the Huygens instruments before separation.

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...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
