“…Cooling the bit is another advantage of the utilization of compressed gas in a drilling system. On Mars, the pressure of the atmosphere is very low; consequently, there is no need to supply a great amount of gas to be compressed as drilling fluid in the pneumatic technique [105]. A new, innovative method for the evaluation of volatile content in an arbitrary soil has been developed in 2020 [125].…”

“…The third layout in Figure 3c is pneumatic drilling, proposed by [105]. They found that a compressed gas (as drilling fluid) can efficiently remove an amount of 6000-9000 The first mechanism in Figure 3a, the most common planetary conventional drilling, is auger drilling, which involves a screw-shaped penetrator facilitating bottom-hole cleaning.…”

From the 2000s onwards, unprecedented space missions have brought about a wealth of novel investigations on the different aspects of space geomechanics. Such aspects are related to the exploratory activities such as drilling, sampling, coring, water extraction, anchoring, etc. So far, a whole range of constitutive research projects on the plate tectonics, morphology, volcanic activities and volatile content of planetary bodies have been implemented. Furthermore, various laboratory experiments on extraterrestrial samples and their artificial terrestrial simulants are continually conducted to obtain the physical and mechanical properties of the corresponding specimens. Today, with the space boom being steered by diverse space agencies, the incorporation of geomechanics into space exploration appreciably appears much needed. The primary objective of this article is to collate and integrate the up-to-date investigations related to the geomechanical applications in space technologies. Emphasis is given to the new and future applications such as planetary drilling and water extraction. The main impetus is to provide a comprehensive reference for geoscience scientists and astronauts to quickly become acquainted with the cutting-edge advancements in the area of space geomechanics. Moreover, this research study also elaborates on the operational constraints in space geomechanics which necessitate further scientific investigations.
