On July 10, 2010, the European comet chaser Rosetta performs the fly-by of the comet 21 Lutetia. This is the second cometary fly-by performed by the spacecraft. Rosetta’s mission began on March 2, 2004. The spacecraft has a very complicated trajectory to reach the final target, the comet 67/P Churyumov-Gerasimenko. Rosetta already performed four planetary gravity assists: three with Earth (2004, 2007, 2009) and one with Mars (2007).
