To be able to achieve with the probe Rosetta comet 67P/Churyumov-Gerasimenko astronomers have had to perform complex maneuvers transmitted pulses that each employ over twenty two minutes to get to the commands of the probe sequence then sent for final approach required nearly two days after ten years of travel from Earth and for the first time it was possible to get some close-ups of the celestial body (as big as a quarter of a city), which is rather irregular. The launch of the probe was carried out in March 2004 and has used a series of orbital passes the gravity of the Earth and Mars to increase its speed and reach the comet that from the surveys have an atmosphere of gas and dust and also a coma which that will be highlighted with the progressive approach to the Sun, then in November there should be more direct analysis.
