Description The Carina Nebula contains some of the most massive and luminous stars in our Galaxy and is the best site to study in detail the physics of violent massive star formation and the resulting feedback effects, i.e.~cloud dispersal and triggering of star formation. We are engaged in a comprehensive multi-wavelength study of the Carina Nebula. Our new X-ray and near-infrared data, and mid-infrared data reveal and characterize the full stellar population. We also have used LABOCA at the APEX telescope to obtain a wide-field sub-mm map of the Carina Nebula; while it shows the morphology of the cold clouds in unprecedented detail, these single wavelength data do not permit to determine cloud temperatures, and thus cloud column densities and masses. Here we ask for 7.2 hours SPIRE-PACS time to map the full spatial extent of the clouds (5.4 square-deg.) simultaneously at 5 wavelengths. The HERSCHEL maps will yield fluxes at the critical far-IR wavelengths and allow us to reliably determine cloud temperatures, column densities, and thus cloud masses. This will yield a complete inventory of all individual clouds in the complex, down to cloud masses of 1 Msun, and allow us to detect the youngest and most deeply embedded protostars (down to 0.1 Msun). We will map large-scale temperature gradients and changes in the dust properties that are expected as a consequence of the strong feedback by the massive stars, and establish and compare the clump mass functions in different parts of the complex. By comparison with similar HERSCHEL data for other star forming regions, we can address the question of how the particularly high levels of massive star feedback influence the evolution of the clouds and the star formation process. These HERSCHEL data will also reveal the small-scale structure of the irradiated clouds and allow a meaningful comparison to our dedicated numerical simulations of the disruption of molecular clouds, the origin of...

Mission Description 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.
