Abstract :
PICARD is a French space scientific mission. Its objectives are the study of the origin of the solar variability and the study of the relationship between the Sun and the Earth´s climate. PICARD was launched on June 15, 2010 on a Dnepr-1 launcher. SODISM (SOlar Diameter Imager and Surface Mapper), an instrument of the PICARD payload, is a high resolution radio-imaging telescope. SODISM allows us to measure the solar diameter and shape with an accuracy of a few milliarcseconds, and to perform helioseismologic observations to probe the solar interior. In this article, we describe the SODISM telescope and first results in space.
