Recently, countries around the world pay more attention to the construction of lunar bases. Many of the lunar polar points where lunar bases are expected to be constructed in the future are steep terrain such as crater central hills, rims, vertical holes, volcanoes and valleys. Although it exists, we try to land on stable terrain by the guidance control of the spacecraft. However, it has also been confirmed that guidance control causes the spacecraft to have a residual horizontal velocity with respect to the terrain, which is the cause of the spacecraft overturning. In this paper, it aims to prevent overturning even with a horizontal velocity. we verified a relationship between foot pad shape and foot pad angle by using RFT model between spacecraft and surface of the celestial body. As a result, it was found that the fall can be suppressed most when pad shape is 174 deg and when pad angle is 19 deg.
