Like most of its lunar predecessors, SMART-1 will conclude its scientific observations of the Moon through a small impact on the lunar surface. This is planned to take place in the lunar Lake of Excellence, located at mid-southern latitudes. A trim manoeuvre at the end of July has determined that the impact will most likely occur on 3 September 2006 at 07:41 CEST (05:41 UT), or at 02:36 CEST (00:36 UT) on the previous orbit due to uncertainties in the detailed knowledge of the lunar topography.
If impacting on 3 Sept at 07:41 CEST, SMART-1 will touch the Moon at the lunar coordinates 36.44º South and 46.25º West. If impacting on 3 September at 02:36 CEST the lunar coordinates will be 36.4º South and 43.5º West.
The Lake of Excellence is very interesting from the scientific point of view – it is a volcanic plain area surrounded by highlands, but also characterised by ground mineral heterogeneities.
“We call for ground-based observations mostly to study impact physics, the release of spacecraft volatiles, and the lofted soil mineralogy,” says Bernard Foing , SMART-1 Project Scientist at ESA. “We look for fast imaging of the impact and of the associated ejected material, and for spectroscopic analysis, for example to find hints about the mineralogy of the impact area.”
“Even if the impact at 2 kilometres per second is of modest energy, the plume might be observable if it reaches sunlight, with an amateur telescope or binoculars,” continues Foing. “For sites not covering the time of impact, we ask for context observations before and after impact to look for the ejecta blanket”.
A number of worldwide observatories have already confirmed their participation to the campaign. They include the network of VLBI Very Long Baseline Interferometry and radio observatories, the South African Large Telescope SALT, the Calar Alto observatory in Andalucia, Spain, the ESA OGS Optical Ground Station at Tenerife, Spain, the CEA Cariri observatory in Brazil, the Argentina National Telescope, the Florida Tech Robotic telescopes, NASA IRTF and Japanese telescopes at Hawaii, as well as a number of professional and amateur astronomy telescopes around the world, and the ODIN observatory from space.
ESA invites the scientific community and amateur astronomers to join in the observation campaign. For more information follow this link.

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...
