With Artemis II, SLS could become the most powerful rocket ever to launch humans. Its four main engines burn roughly 700,000 gallons of ultra-cold fuel, producing enough oomph to keep eight Boeing 747s aloft. Future versions of SLS, if they come to fruition, could deliver even greater power.

Artemis isn’t just about returning to the Moon. It’s about building the systems needed to operate beyond Earth orbit.

NASA’s SLS and Orion rolled to the launch pad for the Artemis 2 mission Jan. 17, though uncertainty remains about when the mission will be ready to launch.

NASA officials have confirmed the Artemis II rocket is rolling out on Saturday morning from the Kennedy Space Center.
