Landing robotic spacecrafts and humans on the surface of Mars has become one of the technological needs for humans. To accomplish this intent, we need to land an enormous number of cargoes, crewed modules, scientific laboratories and return vehicles on Mars. In this entailing condition, there are many incidences of the crash landing of landers leading to complete demolition of lander modules. Crash landing occurs due to numerous circumstances. Significant problems and their proportions were illustrated in Fig.1. Moreover, existences of deformable shock absorbers like aluminium honeycomb and crushable carbon fibres in landing gears are not feasible for high scale mass and crewed landing, as a consequence it may cause impairment of landing module. Furthermore, in the interim of EDL performance, one of the most challenging tasks for lander is landing and switching EDL events within the limited span of 5 to 8 minutes. Scrutinizing this concern, we are proposing a novel shock absorbing landing gear system that will be more accomplishable for large-scale and frequent landing missions. This paper relies on the theoretical proposal for the practical design of landing gear system and we expect that subject to any obstruction in EDL sequence, this mechanical system will enable soft-landing thereby increasing the probability of success in forthcoming landing missions. Hence, our ultimate aim is to protect lander modules and its instruments during the course of landing phase.
