Special vehicle will be developed for asteroid mining



NASA :
Because of asteroids extremely low gravity, normal mining methods may not be practical and unusual methods may be required. This innovative asteroid mining vehicle is designed to be used with the shroud in the previous figure. As the robotic vehicle moves across the asteroid, it is held to the surface by tethers. The vehicle has rotating paddle wheels that dig into the regolith and throw loose materials out from the asteroid to be caught by the shroud.
