NASA takes Artemis II rocket to launch pad
Digest more
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.
With launch potentially just three weeks away, the agency is working tirelessly to get the SLS rocket, Orion spacecraft, and the Artemis 2 crew ready for liftoff.
