We present preliminary results of a photometric program aimed to study the rotational properties of the population of Mars-crosser asteroids by means of CCD photometry. We use a set of small robotic telescopes located in the Teide Observatory (Tenerife, Spain) and the Isaac Aznar Observatory (Alcublas, Spain). A total of 54 Mars Crossers were observed at the moment of writing this abstract. For 51 of them we were able to obtain complete light-curves and accurately derive their rotation period. We also observed 7 near-Earth asteroids and several main belt asteroids that appear in the images of the MCs.
