The role of Cubesats and small payloads used for Low Earth Orbit (LEO) missions is evolv-ing in recent years from instrumentation used purely for educational and student purposesto complete space systems capable of participating in interplanetary missions. In this con-text, these small satellites need to be adapted to the hostile environment in which they willoperate and must be able to cope with the problems of thermal control, communication,radiation and vibrations.Cubesats like MarCOs, LICIA Cube, Milani, Juventas and others will narrow the gap thatleads to the cost reduction for space, the use of constellations of small satellites, Commercialoff the shelf Components and miniaturized satellites for exploration of our solar system andbeyond.This thesis presents some analyses for the adaptation of a payload previously used onlyfor LEO missions to the HERA interplanetary mission. These analyses will mainly concernthe design of a housing that will contain the instrument in question, that is a hyper-spectralimager, in particular from a mechanical, thermal and radiation protection point of view.The characteristics of this mission will be presented to understand the preliminary designdrivers, methodologies and results will be illustrated during each step of the design phase.
