We are going to perform 3 experiments preceding to the development of HOPE. We performed OREX taking the opportunity of H-II TF#1 on Feb.4. 1994. We report a result of one of the main purpose of OREX, acquisition of fundamental data of aerothermal- and aerodynamics during reentry. As to aerothermaldynamics, we evaluated comparison between wind tunnel test data and values estimated from Fay&Riddell method before a flight experiment. After that we estimated heating rate induced from fight orbit using Fay&Riddell method validated before. And we calculated a temperature at the stagnation point using thermal-analysis model, then we compared the value with flight data. As to aerodynamics, we compared flight pressure data with estimated value.
