Materials - Nanosims will analyze the dust samples collected by Stardust

Seven French teams working in six CNRS laboratories take part in the first analysis of the samples brought back on Earth on 15 January by the American probe Stardust. Stardust collected grains of dust in an "aerogel" of silica during its flyby of the comet Wild-2 in January 2004, less than 500 km from the core of its head. The NanoAnalyses Laboratory (CNRS/Muséum National of Natural History) will draw up isotopic cartographies of ten grains with a resolution lower than 0,1 micrometers, thanks to the Nanosims probe marketed by the Cameca company. This ionic microprobe, a very particular microscope, is able to recognize each element constituting the material observed. The Nanosims probe is the result of a collaboration between the researchers of Onera's "Materials and Structures" division, Professor George Slodzian's research unit at the Paris-Sud University and the Cameca company. The Nanosims probe has already been installed in great establishments of research like the Washington University in Missouri (US) or the Max Planck Institute in Mainz (Germany).
