The Standup M-Set Moon Drilling Stability II rig provides a means for structure operators to improve the fine control their moon drill service modules have over the moon chunk extracted by their Upwell Refinery structures. The benefits of this rig include a longer period of time in which a moon chunk can be manually fractured before it fractures on its own, a more compact asteroid field, and longer lasting asteroids created by the chunk fracture. Standup is a proprietary system that uses a Structure Autonomous Nanoassembly Device (Upwell) containing integrated template software, a nanoassembler array and sufficient nanomass to enable the construction of a variety of service modules, structure modules and structure rigs when inserted into the appropriate slots on a structure built with Upwell technology. Note: Only one rig of the same type, counting both tech variations, may be fitted at the same time on a structure.
