We will describe the motivations and implementation of the ongoing 204 orbits Hubble Ultra Deep Field Followup program complementing the HUDF data and aimed at obtaining combined ultradeep images in the visible and near-IR for three fields in and around the HUDF. The main scientific motivation is the search of galaxies at redshift 7 and higher in order to identify the objects responsible for the reionization of neutral hydrogen in the Universe. After providing a brief project status, we will present our preliminary results on the first of the three fields.
