As the National Aeronautics and Space Administration (NASA) plans for the next launch of the space shuttle, a critical aspect of the programs safety is being assured by 5 million pieces of data collected recently by the National Institute of Standards and Technology (NIST).
To help prevent a repeat of the 2003 accident when launch debris damaged the shuttle Columbia, causing it to break up on re-entry, NASA has begun illuminating shuttles with tracking radars during launches and ascent to detect and quantify potential hazards. Concerns about possible disruption of onboard electronic guidance and control systems led NASA to request NISTs help in determining how much radar energy can penetrate the orbiter in key locations.
During the launch of Discovery in July, radar was used to track debris during ascent and NASA considered the NIST shielding data vital to the resumption of shuttle flights.

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...
