Rosetta reveals a little more about Count 67P Tchouri

Rosetta, the ESA probe thus continues to revolve around comet 67P Tchouri, and gradually reveals all its facets.

Rosetta The Osiris high-definition photo module made it possible to highlight the atypical shape of the comet, formed by two blocks separated by a finer structure and whose origin remains unexplained.

Observations thus confirm a composition rich in organic materials. The surface of the comet presents an astonishing diversity of geological structures resulting from erosion phenomena, including undulations identical to those which have already been observed on the sand dunes of Mars.

Rosetta Tchouri 1 "We were surprised by the variety of geological structures" shares Hans Nilsson of the Swedish Institute for Space Physics. "The comet's atmosphere seems to be unevenly distributed around the nucleus", he adds.

Tchouri keeps traces of the primitive matter of the solar system, materials which could be studied by Philae upon waking up in a few months, and which could teach us more about the formation of our system and our Earth.
