Rosetta will follow the trajectory

This is what has been achieved today, under the eye technicians gathered in central control of ESA in Darmstadt, Germany, while the European Space Agency begins broadcasting close-up images of the comet . This success is however only the beginning of another phase of the mission, where all specialists will be on deck to put Rosetta on an orbit around the comet elliptical, time to get close enough. This approach is already difficult. Even if a 3D reconstruction of the comet was made, its mass is not known precisely and engineers at ESA can not know how fast an orbit, even ephemeral, can be obtained.

Rosetta will follow the trajectory around the comet 67P / Churyumov-Gerasimenko. The first triangles, increasingly small, used to accurately measure the gravitational field around this small body mass insufficiently known. Adjustments, so updates on the motor will be needed to hold the probe in an elliptical orbit in September, approaching 30 km or less than 10 km if the vent is not too bothersome. It was at this point that Philae will fall off and land. Note: the position of the solar panels that throughout this dance must remain properly oriented with respect to the Sun. © CNES
