The Telios Standard Module is a unit of transport that was developed in the early years of interplanetary shipping. Larger than previous incarnations of shipping containers used on Telios Prime for decades, the Telios Standard Module, or TSM, is fully sealed, environmentally supported transport module, with a cubic format that can accommodate practically all types of material to be transported. There are also specialized TSMs designed for the transport of hazardous or otherwise unsuitable cargo. Telian cargo capacities are rated as a numeric value of TSM.
