Landscapes from the ancient and eroded lunar far side

17.07.2006
This image, taken by the advanced Moon Imaging Experiment (AMIE) on board ESA's SMART-1 spacecraft, shows a highly eroded highland area on the lunar far side, close to the equator.

AMIE obtained this image on 1 January 2006, from a distance of 1483 kilometres from the surface, with a ground resolution of 134 metres per pixel. The imaged area is centred at a latitude of 4.2º South and longitude 98.4º East.

The Moon's rotation is locked to the Earth, that is the Moon always presents roughly the same side to the Earth. We call the side facing the Earth the ‘near side’, while the side facing away is the ‘far side’.

After the first lunar missions orbited the Moon, it was discovered that unlike the near side, the far side is lacking large lava plains, the so-called ‘maria’. The far side is mainly composed of heavily cratered highlands, while only very small areas contain smooth lava plains.

The reason for this difference between near side and far side is not exactly understood. Could the tidal pull of the Earth on the Moon - just like the Moon introduces tides on the water bodies of the Earth - have resulted in such a difference?

The modelling of previous topography and gravity measurements indicate that the solid crust is thinner on the near side. As a consequence, large impacts could excavate the crust more easily on the near side, and so lava had an easier way to flow out and create maria formations.

This image shows some highly eroded highland area on the lunar far side. Many craters are almost not longer visible, as they were destroyed by subsequent impacts.

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

Im Focus: Entangled atoms shine in unison

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
