- Abstract
The two science missions Herschel, an observatory-type mission, and Planck, a survey mission, are combined in one programme within ESAs long-term science programme. Herschel, an observatory mission, will target the largely unexplored infrared and sub-millimetre part of the electromagnetic spectrum from 60 to 670 microns with three scientific instruments. As a survey mission, the objective for Planck is to image systematically the whole sky simultaneously with two scientific instruments in nine frequency channels between 30 and 900 GHz to unravel the temperature fluctuations, the anisotropy, of the cosmic background radiation. This paper will focus on the first steps achieved in the verification of the challenging performance requirements demanded by the payload, and especially in the cryogenic domain . For both satellites, which will be launched from the European Space Port in Kourou, French Guiana, on a single Ariane 5 launcher in 2008, the orbits will be Lissajous orbits around the 2nd Lagrange Point L2 of the Earth-Sun system.
