Jupiter was observed on October 31, 2009 with the Photodetector Array Camera and Spectrometer (PACS) onboard the Herschel Space Observatory, as part of the guaranteed time key program "Water and related chemistry in the Solar System (HssO)". PACS is as an integral field spectrometer which covers the wavelength range between 55 and 210 µm with a resolving power varying from 940 to 5500. The apparent disk diameter of Jupiter was 41", and it was spatially resolved with 5 * 5 spatial pixels where each spaxel have a projected size of 9.7" * 9.7" on the sky. The observed spectra show numerous spectral features due to NH3, PH3, HD, CH4, and stratospheric H2O. We will present the initial data analysis which provides new insight into the abundances of these observed species. In addition, upper limits on the abundances of hydrogen halides (HF, HCl, HBr, and HI) will be also discussed.
