Research on the Ground Test Technology of Lunar Landing and Ascending

Reliable and safe lunar landing and ascending is the basic condition for lunar exploration. It is also a key technology in the probe development,therefore ground test is required. As the environment on the ground are different from that on the moon,the operation features of the probe on the ground are also different. The design and the implement of the ground test are difficult. The design points of the lunar landing and ascending and the critical factors of the ground test are analyzed. The existing defects in current test technology are pointed out. A ground test verification scheme using the impetus of the probe itself for landing and ascending is proposed,and its feasibility is validated by the dynamic simulation. The extended application of the scheme is putted forward. The related research provides reference for the future development of Chinese lunar or planetary probes.
