An article entitled "Geologic characteristics of the Chang'E-3 exploration region"was published online for SCIENCE CHINA Physics, Mechanics & Astronomy on January 21, 2014. It presents some new results on the geologic characteristics of the Chang'E-3 exploration region.

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.

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

Im Focus: Fraunhofer ISE Develops Highly Compact, High Frequency DC/DC Converter for Aviation

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.

Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
