The NASA Space Launch System (SLS) is designed to send the Orion capsule and its crew beyond low Earth orbit. Artemis II will feature a crew flying around the Moon, leading to Artemis III's planned lunar landing.

Orion includes advanced life support, radiation protection, and a large thermal shield. It has a propulsion system with 33 engines and incorporates over 150 3D-printed parts. The capsule consists of a launch abort system, service module, and crew module, each with specific propulsion capabilities for navigation and safety.
