Rocket fueling 'go' has been given

Artemis II Launch Director Charlie Blackwell-Thompson has given the "go" for ground teams to begin fueling the SLS rocket, a procedure known as tanking.

Fueling begins with the chilldown step, a critical process that cools the rocket's plumbing and engine systems to super-cold cryogenic temperatures so there aren't any issues when ground teams begin to load the fuel of cryogenic liquid hydrogen and liquid oxygen.

Watch Artemis II live at Kennedy Space Center

NASA is broadcasting a live feed of the Artemis II moon rocket from the Kennedy Space Center on Merritt Island, Florida.

Teams are activating the ground launch sequencer, the computer that will initiate terminal count -- the final, automated 10 minutes of launch countdown -- which will tell the rocket when to lift off.

Engineers are also initiating the air‑to‑gaseous nitrogen changeover inside the rocket's cavities. NASA says atmospheric air is replaced with inert nitrogen gas, which creates a stable environment before fueling operations.
