Th.us'ūng I is the closest planet to the sun of the [Th.us'ūng system](https://robertsspaceindustries.com/galactapedia/article/V8WeExnJge-thusuung-system), [Xi'an Empire (SaoXy'an)](https://robertsspaceindustries.com/galactapedia/article/0n96JkwNo9-xian-empire). A terrestrial planet, it has a thin mantle that partially exposes its iron core. The [Xi'an](https://robertsspaceindustries.com/galactapedia/article/ReJwN9KJEj-xian) government prohibits commercial mining on Th.us'ūng I, and instead utilizes it as a testing area for mining technology that is designed for hostile environments. In addition, some major Houses have special dispensations to conduct related experiments here under the direct supervision of government representatives.
