The Department of Space Research has the responsability to coordinate space activities of the IPGP, to prepare future missions, and, if necessary, to design and produce embarked instruments. The Department is located on the site of Parc de Saint Maur, 4 avenue de Neptune, in Saint Maur des Fossés (94, France). The observatory of Saint Maur is situated at 5 minutes on foot from the RER station Parc de Saint Maur (Line A2, direction Boissy-Saint Léger, RER map,Street map from D to A). The observatory of Saint Maur

Direct participation of the IPGP and of the Department in space missions is mainly done in the field of geophysical observation of the Earth from space, and in the field of exploration of Mars.

In parallel of these technical activities, the Department develops several research activities, in observation of the Earth as well as in planetology.
