Abstract:SD2 (Sampler, Drill and Distribution System), is one of the instruments onboard the lander Philae of the Rosetta mission. This system is of primary importance for the lander mission since it is in charge to collect comet's soil samples at different depths and to distribute them to different instruments for analysis. SD2 has to meet very stringent requirements in terms of volume, mass and power consumption, operative range and severe environmental conditions. An overview of SD2 is provided, with the description of the sample acquisition and distribution procedure and an outline of the technological innovative aspects.
