2748 20160706140116.0 ASTROimport-905 Thuillot, W. The FP7-ESPaCE project for ephemerides of natural satellites and spacecraft 2013 The European program FP7-ESPaCE is a collaborative activity, which aims at exploiting space and ground-based data for providing new ephemerides of several natural satellites and spacecraft. New technologies applied to the positioning of spacecraft are also studied. ESPaCE addresses also data related to gravity and shape modeling, control point network and rotational parameters of natural satellites. The accuracy improvement of these ephemerides makes them a powerful tool for the analysis of space missions or the preparation of future missions, or for the determination of some physical parameters. This communication gives the preliminary results obtained at the mid-term of this program. NO Lainey, V. Arlot, J.-E. Déhant, V. Gurvits, L. I. Hussmann, H. Oberst, J. Rosenblatt, P. Marty, J.-C.
