The CNES has recently studied the~a ark~r Niverse Explorer mission E~(ar) NE), one of the promising future missions that are studied at pre-phase A level. The objective of the (ar)~ NE mission is the high accuracy measurement of the physical properties of dark matter and dark energy in the universe. To reach this objective, (ar)~ NE is based on the weak lensing gravitational effect: The distribution of the dark matter in the universe is surveyed using measurements of the induced shear on images of background galaxies. The statistics on the shear can be used to constrain cosmological parameters, in particular properties of dark energy. The observation of supernovae of type Ia constitutes also a complementary science objective. The (ar)~NE project proposes the development of a space imager with large field of view, and the present paper focuses on the first design iteration of the (ar)~NE space segment. The spacecraft is a one ton class spacecraft injected in d eostationary Earth 1 rbit Ed El ) with a launcher of Soyuz-Fregat type. All system aspects are presented: science requirements, observation strategies, science data calibration, attitude and control system, orbit, launcher, propulsion, payload design, communication and power system, and avionics.
