A Trace Atmosphere is a type of atmosphere with a pressure of less than 0.1 atmospheres, which requires the use of a vacc suit.
- It is also known as a Type 1 Atmosphere.
Description (Specifications)[edit]
Trace Atmospheres requires a vacc suit. The atmosphere has a pressure of less than 0.1 atmospheres, which requires the use of a vacc suit.
Surface Pressure & Water Properties[edit]
An atmosphere rated as Trace has a mean surface pressure ranging from 0.001 atm to 0.09 atm.

History & Background (Dossier)[edit]
Airless Worlds: A great many worlds in Charted Space have an Atmosphere type of 0 (Vacuum) or 1 (Trace).
- Although a trace atmosphere denotes a thin veneer of gases around a world (such as Mercury), it is of such barely measurable pressures that it may as well be a vacuum. Animal and plant life is non-existent on an airless world, although exotic and incredibly rare examples of vacuum life might exist (...and certainly be worthy of an IISS Scout mission).
- Mainstream sophonts must resort to living in bubble cities, underground settlements and other artificial, sealed environments. It can be difficult for a scout to differentiate these vacuum habitats. Try to take note of distinctive features at these settlements such as interesting geographical locations: at the entrance to a huge mine, straddling a small meteorite crater, along the walls of a canyon, inside old lava tubes, in the caldera of an extinct volcano, inside a network of vast, natural caves ... and so on.
