ESA Space Scientist Detlef Koschny explains why he originally built Rosetta in LEGO®

Space missions are complicated pieces of orbital choreography. When planning a mission, spacecraft engineers must calculate how to point the solar panels towards the Sun, the main antenna towards Earth and the instruments towards the target. ESA Space Scientist Detlef Koschny build a LEGO model of Rosetta mission in order to visualise these precise orientations.
