An international collaboration has grown around the project of Microcalorimeter Arrays for a Rhenium Experiment (MARE) for a direct and calorimetric measurement of the electron antineutrino mass with sub-electronvolt sensitivity.MARE is divided into two phases. The first phase (MARE-1) consists of two independent experiments using the presently available detector technology to reach a sensitivity of m{sub v}{<=}2eV/c{sup 2}. The goal of the second phase (MARE-2) is to achieve a sub-electronvolt sensitivity on the neutrino mass.The Milan MARE-1 experiment is based on arrays of silicon implanted microcalorimeters, produced by NASA/GSFC, with dielectric silver perrhenate absorbers, AgReO{sub 4}. We present here the status of MARE-1 in Milan which is starting data taking with 2 arrays (72 detectors). In this configuration a sensitivity of about 5 eV can be achieved in two years. We describe in details the experimental setup which is designed to host up to 8 arrays (288 detectors). With 8 arrays, two years of measurement would improve the sensitivity to about 3 eV. This talk reports on the activity of the group for the MARE project in Milan.
