Taking a SMART sidelong look at Lunar Peak of Eternal Light

26.09.2008
Three-dimensional views of the mountainous terrain surrounding a “peak of eternal light” near the Moon’s south pole have been released by the European Space Agency. Dr Detlef Koschny will present the images at the European Planetary Science Congress in Münster on Friday 26th September.

Images taken by the AMIE camera carried by ESA’s SMART-1 mission have been used to create digital elevation model of the peak, which is almost continuously exposed to sunlight.

“AMIE is not a stereo camera, so producing a 3-D model of the surface has been a challenge,” said Dr Koschny. “We’ve used a technique where we use the brightness of reflected light to determine the slope and, by comparing several images, put together a model that produces a shadow pattern that matches those observed by SMART-1.”

AMIE took a total of 113 images of the peak, located close to the rim of the Shackleton Crater which lies on the lunar south pole. In all but four of the images, the peak was illuminated by sunlight. This is of particular interest in planning future manned missions to the Moon, as it would mean that solar panels could be used almost constantly to generate an electricity supply for a lunar base.

In addition, the shadowed craters nearby are in constant darkness and may hold water ice deposited over millennia by cometary impacts and hydrogen and oxygen particles contained in the solar wind. This potential water supply would also be a vital resource for any lunar base.

The team, led by Dr Björn Grieger of ESA’s European Space Astronomy Centre in Madrid, selected five of the AMIE images showing the peak illuminated from different angles. They mapped all the pixels onto a grid, defining the bright and dark areas. The data from the five images were then compared to produce estimates of the slope angles and the rendered elevation model was iteratively adjusted to produce a shadow match. The original AMIE images were then projected onto the retrieved model. To clearly visualise the topography, the elevation has been exaggerated five times.

SMART-1 orbited the Moon between November 2004 and September 2006, covering a full seasonal cycle.

Im Focus: A step towards controlling spin-dependent petahertz electronics by material defects

The operational speed of semiconductors in various electronic and optoelectronic devices is limited to several gigahertz (a billion oscillations per second). This constrains the upper limit of the operational speed of computing. Now researchers from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg, Germany, and the Indian Institute of Technology in Bombay have explained how these processes can be sped up through the use of light waves and defected solid materials.

Light waves perform several hundred trillion oscillations per second. Hence, it is natural to envision employing light oscillations to drive the electronic...

Im Focus: Freiburg researcher investigate the origins of surface texture

Most natural and artificial surfaces are rough: metals and even glasses that appear smooth to the naked eye can look like jagged mountain ranges under the microscope. There is currently no uniform theory about the origin of this roughness despite it being observed on all scales, from the atomic to the tectonic. Scientists suspect that the rough surface is formed by irreversible plastic deformation that occurs in many processes of mechanical machining of components such as milling.

Prof. Dr. Lars Pastewka from the Simulation group at the Department of Microsystems Engineering at the University of Freiburg and his team have simulated such...

Im Focus: Making the internet more energy efficient through systemic optimization

Researchers at Chalmers University of Technology, Sweden, recently completed a 5-year research project looking at how to make fibre optic communications systems more energy efficient. Among their proposals are smart, error-correcting data chip circuits, which they refined to be 10 times less energy consumptive. The project has yielded several scientific articles, in publications including Nature Communications.

Streaming films and music, scrolling through social media, and using cloud-based storage services are everyday activities now.

Im Focus: New synthesis methods enhance 3D chemical space for drug discovery

After helping develop a new approach for organic synthesis -- carbon-hydrogen functionalization -- scientists at Emory University are now showing how this approach may apply to drug discovery. Nature Catalysis published their most recent work -- a streamlined process for making a three-dimensional scaffold of keen interest to the pharmaceutical industry.

"Our tools open up whole new chemical space for potential drug targets," says Huw Davies, Emory professor of organic chemistry and senior author of the paper.
