Obtaining rock samples by drilling is an important method of asteroid detection. Due to the
strict restrictions on the weight, volume, and weight on bit, conventional drilling devices are …

Water ice in the polar regions of the Moon is crucial for potential manned lunar bases and as
a source of fuel for rockets. Confirmation of the presence requires in-situ sampling which …

Rock drilling is widely used to explore and mine energy resources. It has also been used to
extract samples to study the earth's geological composition and topography and to explore …

Ultrasonic drills, which can sample rocks using a lower weight on bit and lower power, are
more suitable for sampling on a minor planet than conventional drills. To remove cutting …

The collection of lunar regolith with complete stratigraphic information is the key to analyzing
the evolution and composition of the moon. To keep each sample's stratification for further …

Achieving high-speed punching is crucial for improving the efficiency of transplanting
operations. However, existing devices cause significant soil disturbance at high velocities …

Compared with other technical solutions, sampling the planetary soil and returning it back to
Earth may be the most direct method to seek the evidence of extraterrestrial life. To keep …

The bit and object thermal problem was investigated in this study with particular regard to
the drilling of lunar soil simulant. The discrete element method (DEM) was used to establish …

Dry drilling only with the assistance of an auger is a reliable and realistic approach to
remove abundant soils from the side of a bit in the harsh, dry conditions on the Moon. Based …

Drilling is a widely used method for exploring extra-terrestrial bodies and seeking
information on astrobiology, material composition, and evolution of the universe. The bit …
