The European Space Agency's Planck satellite, launched on 14 May 2009, is the third-generation space experiment in the field of cosmic microwave background (CMB) research. It will image the anisotropies of the CMB over the whole sky, with unprecedented sensitivity ( ΔT T ∼ 2 × 10 −6 ) and angular resolution (∼5 arcmin). Planck will provide a major source of information relevant to many fundamental cosmological problems and will test current theories of the early evolution of the Universe and the origin of structure. It will also address a wide range of areas of astrophysical research related to the Milky Way as well as external galaxies and clusters of galaxies. The ability of Planck to measure polarization across a wide frequency range (30−350 GHz), with high precision and accuracy, and over the whole sky, will provide unique insight, not only into specific cosmological questions, but also into the properties of the interstellar medium. This paper is part of a series which describes the technical capabilities of the Planck scientific payload. It is based on the knowledge gathered during the on-ground calibration campaigns of the major subsystems, principally its telescope and its two scientific instruments, and of tests at fully integrated satellite level. It represents the best estimate before launch of the technical performance that the satellite and its payload will achieve in flight. In this paper, we summarise the main elements of the payload performance, which is described in detail in the accompanying papers. In addition, we describe the satellite performance elements which are most relevant for science, and provide an overview of the plans for scientific operations and data analysis.

BACKGROUND Prior research focused on the impact of being in a partnership on quality of life from a cross-sectional perspective; the impact of partnership histories has not yet been investigated. OBJECTIVE Based on the life-course paradigm and the theory of cumulative (dis)advantages, we address this research gap. METHODS Using pairfam data, we analyse the influence of partnership histories between ages 14 and 41 on depressiveness, overall life satisfaction, and partnership expectations. We demonstrate the additional value of using life-course clusters over simple sequence characteristics by showing that more detailed and accurate conclusions can be drawn. RESULTS Results highlight that both men and women benefited from being in a stable cohabitational union. 3 Gender differences were found among those who were negatively affected by not establishing a stable cohabitational union. Among men, longterm singles were significantly more depressed, less satisfied, and had more negative partnership expectations than their cohort peers. Among women, those with a history of unstable relationships were less satisfied and had more negative partnership expectations.
