A Mars exploration landing buffer device comprises three or four sets of landing legs symmetrically distributed on the periphery of a Mars exploration lander body mechanism. Each set of landing legs is composed of a foot pad (1), a main leg (2), an auxiliary leg (3) and an unfolding locking mechanism (4), wherein the foot pad (1), the main leg (2), the auxiliary leg (3) and the unfolding locking mechanism (4) of the same set of landing legs are connected with one another through universal joints or rotating shafts, and the main leg (2), the auxiliary leg (3), the unfolding locking mechanism (4) of each set of landing legs and the lander body mechanism form a four-bar mechanism so that the landing buffer device can be overturned outwards up and down. The upturning folding structure enables the mass center of the lander to move forwards, the movement stability of the lander in an entering stage is improved, in addition, energy is absorbed through own movement deformation of buffer cellular structures in the main legs (2) and the auxiliary legs (3), soft landing of the lander is achieved, and the device can be applied to design of soft landing buffer mechanisms for landing detection on a planet or a satellite with atmosphere.
