SpaceX is moving forward with loading propellant, the company announced via X, the platform formerly known as Twitter.

The propellant includes liquid methane and superchilled liquid oxygen — or “LOX” — which serves as the oxidizer. Both are pumped into the rocket from nearby tanks.

The rocket holds millions of pounds of fuel and oxidizer. Super Heavy alone can hold up to 8 million pounds (3,700 metric tons) of propellant, while the Starship spacecraft can hold another 3 million (1,500 metric tons).
