Description Within only a few arcminutes, the nearby rho Oph A cloud core harbours distinctly different physical regions, i.e. gravitationally unstable dense cores, a highly collimated bipolar outflow from a class 0 protostar and photon dominated regions (PDRs) in the cloud surface layers. These regions are also spatially well separated and offer the opportunity to study in great detail the different chemistries at work, i.e. grain surface reactions, shock chemistry and UV-controlled photochemistry, all on the r^ant physical scales (< 1e16cm). The different chemistries, in turn, give rise to variations in elemental and molecular abundances, which control the energy balance of the source regions and provide feedback onto the chemistry. Although particular in some respects (detecatable amounts of O2 and H2O2), rho Oph A offers the opportunity to obtain v ital general information regarding the physics and chemistry of star forming regions. We propose the extensions of our water map to include all source regions, most of which were previously not covered, as the currently available map is limited to the outflow. Simultaneously with the two ground state lines of ortho-water at 557 GHz and 1669 GHz, we also obtain the spatial distribution of the ground state line of ammonia and of a higher excitation H2O line, respectively, with HIFI. In addition, to address the still enigmatic oxygen chemistry, we propose a limited map with PACS of the elemental oxygen fine structure lines at 63 and 145 micron. The total observing time amount to 10.7 hours, which is an inexpensive investment for such a valuable Herschel legacy as the proposed program.

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.
