#Artemis #NASA #SLS

planned 30 minute hold of course. at T-10 minutes. The upper stage isn't even filled yet

#Artemis #NASA #SLS
Planned hold.

01:04am EST launch window will slip. got 2 more hours of wiggle room

#Artemis #NASA #SLS

Range safety officer is Testing if they can possibly blow up the big rocket remotely.

I got a good feeling they might actually launch this monstrosity now

going to be exciting!

#Artemis #NASA #SLS Still planned hold. No estimate on terminal count
#ICPS upper stage at 95% LH2
Rest of the tanks are at topping mode

#Artemis #NASA #SLS

All four tanks are full and in replenish mode.

#Artemis #NASA #SLS No additional risk of caulk falling off and causing damage.

Red box shows darker area when RPV "Caulk" was peeled off during hurricane

still got more than an hour of wiggle room. Got a 2 hour Launch window and GODAMMIT we are going to use all of it!

wondering if the #SLS uses a soft or hard caulk and if you need 2 hands to apply it.

yes i am getting a bit punchy

#Artemis #NASA #SLS
Polling about to start!

@Kinnison

He really go into the adderall then.

@Kinnison Just as long as they don't accidentally blow up the rocket while they're testing to see if they can blow up the rocket. It doesn't need to be that exciting.
