The Dark Universe Explorer (DUNE) mission is a wide-field space imager which will make a full sky map of large scale structure. DUNE will place definite constraints on dark energy through its effect on the distribution of matter in the Universe.
Recent cosmological measurements have revealed that the expansion of the Universe is undergoing acceleration. This phenomenon, referred to as ‘Dark Energy’, poses one of the most pressing questions in fundamental physics. The Megacam instrument built by DAPNIA has been used over the last few years to derive some of the strongest constraints on this mysterious component. A probe of strong potential to elucidate the nature of dark energy is now the observation of SZ-Clusters, in which DAPNIA is committed through the Olimpo Balloon and the Planck satellite that will fly in 2008. In the longer term, DAPNIA has a leading role in two future experiments focussing on the nature of dark energy: HSHS, a radio interferometer, and DUNE, a space mission recently proposed to ESA.
