Return exploration missions foresee capsules re-entering the earth atmosphere at high velocity without the usage of a (supersonic) parachute: capsule stability has then to be guaranteed from hypersonic conditions down to the subsonic regime at landing.During there-entry, the capsule shape will change due to Thermal Protection System (TPS) recession and the CoG will shift backward due to TSPmass loss. In such a situation capsule stability might deteriorate becoming critical.The proposed study will focus on quantifying recession rates for a typical ablative material via wind tunnel tests. A special emphasis will be devoted to the wind tunnel measurement technique allowing shape recession.
