The SLS is a set of parts that, when combined, usually make up the 1st stage of powerful or multi payload rockets. The SLS contains the SLS Core Stage, SLS Solid Boosters/SLS Solid Advanced Boosters and the SLS Payload Adapter.
These parts are unlocked in the Sandbox after Mission 22 is completed.
- This is one of the only rockets that can launch itself into space with just one stage.
