Programme details

Three times during 2000 and 2006, Jean Duprat, physicist at the nuclear and mass spectrometry center (CSNSM) of Orsay, went with his team to Concordia, the franco-italian scientific base in the south pole, in order to collect micro-meteorites by melting the snow that they contain.
The target of the campains and studies they follow (inter-linked with the data collected by Stardust, the NASA probe which has brought back at the end of 2006 samples from the Wild 2 comet’s tail) is to understand, thanks to witness dust, the first moments of the primitive solar system, and how our star and its cortege of planets were formed 4,5 billions years ago.
