“…While walking, the pronation/supination range of motion usually does not exceed 10°, but enabling this motion is of great importance in increasing the crewmember lateral stability. Experience highlights the need to optimize the balance between ankle abduction/adduction capability and ankle support [10]. In order to prevent human ankle dislocations, the range of motion of the PSS ankle joint shall be limited.…”

“…Integration of a boot providing ankle rotation, biaxial ankle flexion capabilities and flexible boot sole provide significant benefit for walking mobility on a planetary surface in terms of personnel comfort, security and walking speed over uneven and sloping terrain [10].…”

“…Comfort of the crewmember wearing the suit (intended for exploration of the Moon/Mars) depends to a considerable degree on the footwear, its mass and the availability of custom inserts/profiled insoles. The restraint of the foot within the boot must be optimized in order to transfer lateral loads into the foot comfortably [10]. Figure 10 presents the LTA with assumed places of inserts/pads arrangement.…”

At present advanced projects of the early XXI century are beginning to develop. These projects include lunar base development and manned missions to Mars. The space suit is one of the basic requirements for successful implementation of future programs. The space suit enclosure enables mobility of crewmembers wearing pressurized space suits which will be required to complete these missions. Requirements on Planetary Space Suit (PSS) enclosure design, especially for elements providing mobility of the lower torso assembly will be different from these on orbital space suit enclosure design, intended for zero gravity conditions. The PSS enclosure provides cosmonaut/astronaut movement on planetary exploration surfaces, ascent/descent of the Landing Module ladder, suited crewmember's bending etc. Thus this PSS component will play a considerable role in successful fulfillment of extra-vehicular activity (EVA) tasks on planetary surfaces. The paper comprises the following: n Analysis of the specific environmental conditions and EVA characteristics on the Moon and Mars n Major PSS enclosure requirements n PSS enclosure design concepts analysis n PSS lower torso assembly concept for the Moon and Mars
