The present paper presents a design proposal to develop a platform to test current materials identified as thermal and radiation barriers. This system represents an excellent opportunity to advance the development of aerospace material characterization for materials projected for low earth orbit spacecraft. The system encompasses the use of a Geiger counter and 2 thermistors to monitor and evaluate temperature and cosmic radiation isolation. The monitoring system is currently being evaluated to be included in the AztechSat 1, a Cubesat project from San Jose State University in colaboration with the Universidad Autónoma de Baja California, Instituto Politecnico Nacional de Mexico, Agencia Espacial Mexicana and NASA Ames Research Center to be delivered to the ISS aboard Nanoracks Orbital 2 in April of 2014.
