Directed drilling rods, often referred to as directional drilling equipment, are specialized tools that allow for the precise placement of wells at various angles. Unlike conventional drilling methods, which typically follow a vertical path, directional drilling enables operators to reach multiple reserves from a single drilling site. This not only optimizes resource extraction but also minimizes environmental impact by reducing the surface footprint.
The low-pressure environment presents a range of challenges for human exploration. Spacecraft designs must take into account the effects of low pressure during landing, ascent, and surface operations. Habitats for astronauts will need to be airtight to maintain a safe atmospheric pressure for human survival.

Third, the structure of the drilling rig:
The drill tool is composed of drill pipe, ball tooth drill bit and impactor. When drilling, two drill rods are used to drill. The reverse air supply structure is composed of a reverse motor, a reverse reducer, and a reverse air supply inverter. The reverse reducer is
