Artist concept of the SLS Block 1 configuration.
This illustration shows NASA’s new rocket, the Space Launch System (SLS), in its Block 1 crew vehicle configuration that will send astronauts to the Moon on the Artemis missions. For the rocket’s first flight on the Artemis I mission, it will send an uncrewed Orion spacecraft in an orbit beyond the Moon. SLS, the most powerful rocket NASA has ever built, is the first vehicle designed to meet the challenges of sending astronauts to deep space on missions to the Moon and Mars.
