T-6:35:30 to Possible Scrub or RUD on launch

Eat your peanuts

Fast fill will continue for another hour or so

Oh.. excellent Graphic from #NASA #Artemis #SLS

#Artemis Core stage leak testing LH2 topping and replenish started. . It always leaks, just need to make sure it doesn't leak TOO much
#SLS #NASA

The Interim Cryogenic Propulsion Stage (ICPS) RL10 liquid hydrogen engine system purge is now complete.

#Artemis #NASA #SLS FYI the abort rocket has a fake motor, and fake fuel on board. so if there is an issue the ORION capsule will be lost

Also FYI if one of the 4 main engines fails, the craft can still abort to orbit abd do a secondary mission in low earth orbit

#Artemis #NASA #SLS Core stage liquid oxygen is now full and in 'topping' mode.

Everything going as planned, even a little ahead of schedule.

all waiting for the fucking to happen #nojinx

#Artemis #NASA #SLS
The interim cryogenic propulsion stage main propulsion system, which will give #Orion
the power needed to begin it's journey to the Moon, is now in fast fill for LH2 and LOX.

#Artemis #NASA #SLS
Good shot of happy venting from the #ICPS upper stage. This will "kick" the Orion capsule into a trans lunar injection (get to the moon) on a 4 day journey

90% weather go for launch.
LOX fast fill complete for #ICPS upper stage

Intermittent leak in the core stage being monitored. not an issue at the moment low enough to not be an issue
#ICPS Upper stage still being fast filled with LH2
