Abstract
SOHO is a 3-axis stabilised S/C placed in operational orbit around the Sun-Earth Lagrange 1 point (L1). Service Module (SVM) equipments are placed mainly on the inner side of the four lateral panels, and the thermal design is based on the direct rejection of the units power dissipation via a devoted MLI/Radiator layout to fulfil the requirement, with the aid of heaters. A new MLI composition based on embossed kapton, allowing a 20% reduction on mass budget of MLIs, has been developed and tested on the frame of this project.
