The TPS recession sensor ReGS-HF, developed at the Advanced Ceramics and Composites Lab of the INN, will be part of a test mission that will be launched to space by ARIANE in May 2022 and return to Earth with a velocity of almost 100000km/hr! RegS-HF sensors monitor in real time the state of the heat shield which protects the spacecraft against the intense heat developed during its hypervelocity descent through the atmosphere.
