Video: 3D reconstruction of the comet Rosetta

Video: 3D reconstruction of the comet Rosetta

The images taken by Rosetta "his" comet 67P / Churyumov-Gerasimenko, helped build a three-dimensional model, which has been refined. It will be essential to prepare for the arrival of the Philae lander, as explained astronomer Laurent Jorda, the Astrophysics Laboratory of Marseille and a member of the team responsible for the Osiris instrument Rosetta.

A few days before its historic rendezvous with the comet / 67P Churyumov-Gerasimenko, the spacecraft of the European Space Agency's Rosetta comes close smoothly. This Wednesday, August 6, it will not be quite in orbit around, but will follow a path which will fly together with the comet.

Meanwhile this exciting event that Futura-Sciences is sure to follow, we deliver the secrets of the three-dimensional reconstruction of the shape of the nucleus has been the subject of a previous article . This animation, created by the Laboratory of Astrophysics of Marseilles (Université Aix-Marseille) from images of the Osiris camera is anything but goodies . Indeed, Lam is responsible for the 3D reconstruction of the shape of the core design of the landing operations of Philae, which will be dropped into the comet early November 2014 Module will be necessary to "model the field of gravity around complex kernel and the local slopes on the surface of comet " , explains Laurent Jorda. These two facts can be deduced from the 3D model.
