IHerschel space observatory has been successfully launched on 14 May 2009. It will observe in the 55-672 \mu m wavelength spectral range. Hershel is the only space facility dedicated to this part of the far infrared and submilimetre spectral range. The choice of an operational orbit around L2 provides a stable thermal environment which together with a very low telesope emissivity offers a stable background enabling very sensitive photometric range. I will describe some basic telescope charateristics and scientific objectives of this mission.
