A Sol-Gel-derived magneto-optic nanocomposite consisting of a dispersion of magnetic nanoparticles in a silica matrix was successfully implemented in a magnetic nanosensor based on the Faraday effect. The nanosensor is currently responsible for the orientation of the Spanish research NANOSAT satellite with respect to Earth. This important achievement is the result of a close and fruitful joint research venture, of 7 years between the National Institute for Aerospace Technology and the Materials Science Institute of Madrid. The authors hope that this first Sol-Gel based technological development, now in-orbit, will open new possibilities to apply the enormous potential of the Sol-Gel technology to the design of new materials for challenging space applications aiming to the miniaturization of the satellites, in order to reduce payloads and high costs of space mission.
