“…Some older soviet landers as Luna 16, 20 and 24 reached 1.6 m below the lunar surface [69], while Lunokhod 1 and 2 rovers carried a cone-vane penetrometer to access distances of up to 0.1 m [70]. Drills mounted on landers or robotic equipment have made some tasks at shallow depths on Venus (Venera 13-14 and Vega 2 landers [71]), or performed scooping on the Moon (Surveyor 3 and 7 [50]) or Mars (Viking landers [72]). More recently, space drilling activities took place onboard the Rosetta [73] and Beagle 2 [74] landers and in the Curiosity rover [75].…”

Dessert organisms like sandfish lizards (SLs) bend and generate thrust in granular mediums to scape heat and hunt for prey [1]. Further, SLs seems to have striking capabilities to swim in undulatory form keeping the same wavelength even in terrains with different volumetric densities, hence behaving as rigid bodies. This paper tries to recommend new research directions for planetary robotics, adapting principles of sand swimmers for improving robustness of surface exploration robots. First, we summarize previous efforts on bio-inspired hardware developed for granular terrains and accessing complex geological features. Later, a rigid wheel design has been proposed to imitate SLs locomotion capabilities. In order to derive the force models to predict performance of such bio-inspired mobility system, different approaches as RFT (Resistive Force Theory) and analytical terramechanics are introduced. Even in typical wheeled robots the slip and sinkage increase with time, the new design intends to imitate traversability capabilities of SLs, that seem to keep the same slip while displacing at subsurface levels.

“…The global radar images reveal an array of landforms, some of which appear to be the result of tectonism while others are proposed to be volcanic features produced by a variety of magma types with different viscosities [6][7][8]. The highland tesserae, from which we do not have geochemical data, may contain more felsic compositions hinting at similarities to terrestrial-style continental crust building [9,10]. The tesserae regions are thought to be ancient, and are likely either granitic in composition or represent heavily altered basalt, both pointing to an epoch long since passed in Venus' history.…”
