Cold, but not uninhabitable. Aluminum dust in the high atmosphere makes communication offworld incredibly difficult, only achievable by omninet access or extremely high-power communication systems. All water on the planet is suffused with a certain structure of salt that makes ingestion without a filter extremely distasteful and with long-term downsides to hydration and bodily function. Despite this, local life has evolved to survive it, living in the cold mud and salty lakes. The atmosphere enables it to make a unique alloy of steel ideal for shipbuilding.
