In this programme we propose to study starless cores and the initial conditions of star formation using the Herschel satellite and the combined power of its PACS and SPIRE instruments. As the starting point we have the Planck survey that will provide the first all-sky survey of Galactic cold and compact dust clouds. We will concentrate our study on mid- and high Galactic latitudes. Our program complements the accepted GT and proposed OT programs which target the most prominent regions already in the phase of active star formation. The main objective is to build a coherent observational database representing the entire cold core population in the Galaxy.

Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
