MSS is a space station visited in Missions 11, 19 and 33. In the second 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 and CSgt Nuclear Generator, the latter of which is unlocked at Mission 33 instead.


  • This is the only location where Soyuz modules can be accessed prior to 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.
