MIST (Mercury's Independent Survival Topoformer) is probably the most advanced technology created by Mercury's engineers. This process transforms the Toposphere into a self-sufficient atmosphere capable of withstanding immense blasts. MIST would only be used to defend itself from an immense explosion (the equivalent of the solar system being destroyed). Mercury would probably be the only planet, perhaps to the exception of Pluto and the outer Planetoids, to survive the destruction of the Solar System. After an explosion like this, the newly-created atmosphere would be destroyed, but this would hardly matter because of the self-sufficient Biodome cities on the surface.
