Drilling Systems for Space Mission

Drilling contains two main stages, rotational motion, and a linear motion, which is applying weight towards the rock or the land to collect the dust sample. Curiosity rover drilling system is one of the leading systems in Mars missions, the rover used to investigate and to collect the Martian dust and test it while in space. Moreover, there are tons of drilling systems ideas some are limited in specific sites like InSight lander, and others are portable like Curiosity rover, both are described through this research. Besides, difficulties the engineers faced because of the limitations of different planetary explorations, such as the absence or lack of gravity, the weight on bit, hole cleaning problems, continuous power supplement and the cost of the mission that exceeds millions dollar.
