Is there a replica of the interior of the space station on the ground? For training astronauts and to try out equipment installations.

There are multiple mock-ups of the ISS, for various purposes:

  • The Space Station Training Facility does not have full modules, but it has flight electronics used for mission training. Mockups of the module interiors are provided, including a full Robotics Workstation, but most are of low fidelity.

  • The ISS RS Mockup facility at Yuri Gagarin Cosmonaut Training Center is the Russian training model of the ISS (including the US part).

  • The Cosmonaut Training Center also has the GCTC Neutral Buoyancy Pool, containing a model of the Zvezda module
