The Space Launch System (SLS) is a rocket which is based on the American heavy expendable launch vehicle SLS. It was previously based on the Ares IV and V rockets that were supposed to launch the Orion Crew Exploration Vehicle.

The SLS is comprised of:


  • Parts are unlocked in the Sandbox after Mission 22 is completed.
  • The Artemis 1 mission in real life is the first launch of the SLS.
  • The Exploration Upper Stage is a large 2nd stage in real life, but has not been added to the game.
  • The SLS prior to 1.5.0 was the white variant of the SLS.
