First look: Chang'e lunar landing site

07.02.2019

On Jan. 3, 2019, the Chinese spacecraft Chang'e 4 safely landed on the floor of the Moon's Von Kármán crater (186 kilometer diameter, 116 miles).

Four weeks later (Jan. 30, 2019), as NASA's Lunar Reconnaissance Orbiter approached the crater from the east, it rolled 70 degrees to the west to snap this spectacular view looking across the floor toward the west wall.


Arrows indicate position of Chang'e 4 lander on the floor of Von Kármán crater. The sharp crater behind and to the left of the landing site is 3900 meters across (12,800 feet) and 600 meters (1,970 feet) deep. (LROC NAC M1303521387LR)

Area around lander enlarged by a factor of two relative to the native pixel scale, bright speck between two arrows is the lander. The large crater in the center (just right and below arrows) is about 440 meters (1,440 feet) across. (LROC NAC M1303521387LR)

Because LRO was 330 kilometers (205 miles) to the east of the landing site, the Chang'e 4 lander is only about two pixels across (bright spot between the two arrows), and the small rover is not detectable.

The massive mountain range in the background is the west wall of Von Kármán crater, rising more than 3,000 meters (9,850 feet) above the floor.

Im Focus: Escort service: The role of immune cells in the formation of metastases

Tumor cells use a certain type of immune cells, the so-called neutrophils, to enhance their ability to form metastases. Scientists have deciphered the mechanisms of this collaboration and found strategies for blocking them. This is reported by researchers from the University of Basel and the University Hospital of Basel in the scientific journal "Nature".

A better understanding of the features that define the interplay between cancer cells and immune cells is key to identifying new cancer therapies. Yet, focus...

Im Focus: Invisible tags: Physicists at TU Dresden write, read and erase using light

A team of physicists headed by Prof. Sebastian Reineke of TU Dresden developed a new method of storing information in fully transparent plastic foils. Their innovative idea was now published in the renowned online journal “Science Advances”.

Prof. Reineke and his LEXOS team work with simple plastic foils with a thickness of less than 50 µm, which is thinner than a human hair. In these transparent...

Im Focus: IT in cars: Computers on standby

In the future, cars will exchange data via radio and warn each other about obstacles and accidents. There are currently various radio standards in existence to allow this. However, it is almost impossible to compare them, because the requisite hardware is not yet on the market. To address this lack, researchers at the Fraunhofer Institute for Telecommunications, Heinrich Hertz Institute, HHI have developed a software system that will enable users to analyze the future wireless technology. For manufacturers, this is an ideal solution for testing interesting radio applications at an early stage.

Slowly but surely, the automobile is developing into the autonomous vehicle, as new functions are added with each new generation. Proximity radars are by now...

Im Focus: Making ultrafast lasers faster

Lasers with ultrashort pulses in the picosecond and femtosecond range are often referred to as ultrafast lasers. They are known for their ultra-precise ablation and cutting results. Unfortunately, processing with such lasers takes time. To address this issue, a new research project, funded by the European Commission, aims to make material processing with ultrafast lasers up to a hundred times faster.

Ultrashort pulsed (USP) or ultrafast lasers can do something very unique: They ablate almost any material without causing a thermal load of the adjacent...

Im Focus: New analysis methods facilitate the evaluation of complex engineering data

A further increase in the performance of supercomputers is expected over the next few years. So-called exascale computers will be able to deliver more precise simulations. This leads to considerably more data. Fraunhofer SCAI develops efficient data analysis methods for this purpose, which provide the engineer with detailed insights into the complex technical contexts.

Simulations on supercomputers answer important industrial questions, such as how air flows behave in air conditioning systems, on rotor blades or for entire...
