Space Launch System

This is an artist concept of NASA’s Space Launch System (SLS), the most powerful rocket ever built for deep space missions, including to an asteroid and ultimately to Mars.

The first SLS mission — Exploration Mission 1 — will launch an uncrewed Orion spacecraft to a stable orbit beyond the moon and bring it back to Earth to demonstrate the integrated system performance of the SLS rocket and Orion spacecraft’s re-entry and landing prior to a crewed flight.
