    Core Stage Fueling in Replenish, Go for Upper Stage LOX Loading

    Artemis Logo - red rocket trail, blue arch that represents earth, ARTEMIS text, gray half sphere on a white background

    The Space Launch System’s core stage liquid oxygen (LOX) and liquid hydrogen (LH2) tanks are fully fueled and both are being replenished. During replenish, the propellant that naturally boils off is being replaced to ensure the tanks are at full capacity for launch. A “go” has been given for liquid oxygen loading into the interim …
