What is the Space Launch System (SLS) used for?

Purpose of the Space Launch System

The Space Launch System (SLS) is NASA's heavy-lift rocket designed to send crewed and uncrewed missions beyond low Earth orbit, particularly for Artemis lunar missions and other deep-space objectives.

SLS roles include:

  • Launching the Orion spacecraft on crewed lunar missions.
  • Delivering large payloads, modules, and infrastructure to cislunar space.
  • Supporting flagship science missions requiring high-capacity launch.

Design and capabilities

  • SLS variants offer different payload capacities depending on booster and upper-stage configurations.
  • The system emphasizes high performance and human-rating safety standards for crewed missions.

SLS provides a government-owned heavy-lift capability to execute prioritized deep-space exploration missions in coordination with commercial partners and international collaborators.
