MSS is a space station visited in Mission 11 and Mission 19. In the case of the latter mission, you assist a foreign country by helping them regain control of the MSS. After your first mission to MSS, you gain all the parts that it includes, except for the Soyuz modules.
- This is the only location you can find Soyuz modules before completing Mission 19.
- It is believed that this is the Mir space station even though it was not a secret to the rest of the world in real life.
- One of the parts on this station is a green LOK Docking Module that isn't able to be launched in the Sandbox or later career missions.
