NASA and Boeing engineers successfully completed propellant loading during the seventh core stage Green Run test, wet dress rehearsal Sunday, Dec. 20. The massive Space Launch System (SLS) rocket's tanks were loaded with more than 700,000 gallons of liquid hydrogen and liquid oxygen.

The massive Space Launch System (SLS) rocket's tanks were loaded with more than 700,000 gallons of liquid hydrogen and liquid oxygen.
Engineers working in the Test Control Center monitored all core stage systems during the test as propellant flowed from six barges into the core stage in the B-2 Test Stand at NASA's Stennis Space Center near Bay St. Louis, Mississippi.
First looks at the data indicate the stage performed well during the propellant loading and replenish process. Part of the test was to simulate the countdown with the tanks loaded, leading up to 33 seconds prior to the engines firing. However, the test ended a few minutes short of the planned countdown duration.
The core stage and the B-2 test stand are in excellent condition, and it does not appear to be an issue with the hardware. The team is evaluating data to pinpoint the exact cause of the early shutdown. Then they will decide if they are ready to move forward with the final test, a hot fire when all four engines will be fired simultaneously.
