HOLMES is an experiment aimed at directly measuring the neutrino mass with the calorimetric approach. In its final configuration, HOLMES will deploy 1000 transition edge sensors, each one coupled to a ${}^{163}Ho$ implanted gold absorber. This isotope decays via electron capture on ${}^{163}Dy$, which de-excites by emission of Auger electrons. By measuring the end-point of the electrons spectrum it is possible to extract the electron neutrino mass value. HOLMES is expected to start the data taking by the end of 2017. In this contribution we present the status and perspective of HOLMES.
