- Abstract
JSPEC/JAXA has started the phase-A study and development for the high-speed reentry experiment called DASH-II in the mid summer in 2007. In the mission, a small capsule is inserted into the geosynchronous orbit or a relevant orbit and conducts reentry flight after several orbital circulations. The main objective of the mission is to acquire and demonstrate the reentry/entry technologies associated with future planetary exploration missions such as Mars entry, Venus entry, and high-speed reentry from Moon and from far asteroids. Hayabusa Mk-II (this corresponds to Marco-Polo mission, which was proposed for Cosmic Vision 2018 and passed the first selection stage) is one of the future mission candidates. From the standpoint of the thermal protection material development for the future high-speed reentry missions, the reentry flight experiment should be carried out from GTO or from a relevant (farther) orbit, because the estimated heat flux is high and also the radiative heat flux is not negligible with the corresponding entry velocity. Because the ground heating facilities never duplicate simultaneously the flight environment quantities such as the heat flux, the flow enthalpy, the chemical composition, the dynamic pressure, and the radiation so on, the importance of the real flight experiment is needless to say. DASH-II reentry system is small and costs a little deal and one of the best tools providing us with an excellent opportunity for in-flight qualification of newly-developed materials/concepts and on-board flight measurements. The present paper describes the DASH-II mission plan and recent development status together with further project phase-up strategy.
