Chang'E-3 mission is the second step in China's lunar exploration program. It has achieved the desired engineering goals by successfully soft landing on the lunar surface. Now people are expecting the lander and rover to send back more and better scientific data which is believed to help fulfill its scientific aims and further our understanding of the Moon.
Chang'E-3 landed successfully in the northern part of Mare Imbrium which had never been visited by any lunar landers or rovers. Chinese planetary scientists are now working on the detailed geological interpretation of the exploration area using multi-source data. With morphological and geological analysis, they hope to nail down the major scientific problems for the target area and the scientific discoveries that could be made, thus laying a scientific foundation for the planning of the lunar exploration. Under the leadership of
Professor Long Xiao from China University of Geosciences (Wuhan), a team of young planetary scientists including Jiannan Zhao, Jun Huang and others have mapped the exploration area and acquired large amounts of information on topography, geomorphology, geologic structure and composition of the landing site and its adjacent region. These results will be published in SCIENCE CHINA Physics, Mechanics & Astronomy, Vol. 54, No. 3, 2014 (pages 569).
In this work, the authors studied the geologic characteristics of the Chang'E-3 exploration region, and produced a geologic map of a 1°×1° region centered near the landing site. They also analyzed the topography and slope using the Digital Terrain Model generated from Terrain Camera (TC) images. The exploration region is overall relatively flat and the altitude of the landing site is about 2610 m. The morphology and classification of the impact craters and wrinkle ridges in the area were studied, and the wrinkle ridges were supposed to have different formation mechanisms. After calculating FeO and TiO2 abundances using Multiband Imager (MI) data, two basaltic units are confirmed: the northern part belongs to Imbrian low-Ti/very-low-Ti mare basalts, and the middle to southern part is Eratosthenian low-Ti/high-Ti mare basalts. In addition the thickness of the Eratosthenian basaltic units was estimated, and two traverses for Yutu rover were proposed, laying a scientific basis for the planning of the lunar exploration.
At this moment, Chang'E-3 is conducting its second and third lunar day exploration work as planned, and all the scientific payloads are in good condition. We hope that the Team of Core Scientists on Chang'E-3 Mission Scientific Data Application and Study would make a best use of the newly acquired data to thoroughly study the landing area, and make more discoveries in morphology, geologic structure, material composition and subsurface structure.

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...
