#Artemis #NASA #SLS

"Red team" doesn't actually have Red shirts. I consider this a good idea when dealing with a 2500+ ton rocket full of Rocket fuel

#Artemis #NASA #SLS
Live coverage of the Scrubbed Launch systems has started.

blah blah blah blah

do they get paid by the word?

#Artemis #NASA #SLS 3 Red team members go in, torqueing. 3 red team members leave, Twerking|

yea Red Team!

#Artemis #NASA #SLS

Red Team gave cameras a thumbs up, proving they didn't lose them and can still do Red team stuff

#Artemis #NASA #SLS

LH2 Retanking again

T -01:07:00

#Artemis #NASA #SLS
Range officer is advising a current NO GO due to Radar being down

fuckening #2

LH2 Refilling.

So far nothing is delaying launch assuming range issue is resolved

#Artemis #NASA #SLS LH2 Core stage topping

Range had a bad Ethernet switch on radar. 70 minutes to complete work. Scotty needs to work those miracles to get done by launch window

Currently NO GO. countdown continues

assume there is going to be a hold at T-30 minutes or later

DELAY certain

#Artemis #NASA #SLS
T-0:42:00

Fastfill complete and back in core stage topping.

#ICPS upper stage is on Fast fill LH2 60%

#Artemis #NASA #SLS
Confirmed, Red Team has successfully stopped leak! AWesome work torquing those nuts

Range reporting radar ethernet switch might take longer

DELAY ALMOST CERTAIN

#Artemis #NASA #SLS

Okay. here is where it gets interesting

T-15 minutes there will be a poll for GO/NO GO

Terminal count starts at T-10 minutes
They can get as low as T-90 seconds with a reset, anything pass that and it will be a scrub.

#Artemis #NASA #SLS

WTF Yo-yo Ma? I love him.... but REALLY?

at T-15 minutes? JFC

#Artemis #NASA #SLS
JACK BLACK? WTH

GIB ME ROCKET!

#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!

#Artemis #NASA #SLS
Polling about to start!

GO TIME

#Artemis #NASA #SLS
Polling done
No constraints
GO FOR TERMINAL COUNT LAUNCH!
T MINUS 10 MINUTS AND COUNTING

#Artemis #NASA #SLS

t-6 minutes GO for full pressure

#Artemis #NASA #SLS
GLS is go for LH2 high flow bleed check (T-4M40S)

#Artemis #NASA #SLS
Core Stage APU starts

#Artemis #NASA #SLS
R-25 engine wiggle!

#Artemis #NASA #SLS
ICPS switches to internal battery power

#Artemis #NASA #SLS

ICPS enters terminal countdown mode (T-1M20S)

#Artemis #NASA #SLS

WE ARE GO FOR LAUNCH T-30 SECONDS

WAAAAAAAAAA!

#Artemis #NASA #SLS
T+00:00:00:00 Launch from Mobile Launch Platform 1 at pad LC39B at Kennedy Space Center along with ignition of the SRB

#Artemis #NASA #SLS
T+00:00:02:12 SRB shutdown and jettison at an altitude of 48 km

NOMINAL LAUNCH!

#Artemis #NASA #SLS
T+00:00:03:11 spacecraft adapter fairing panels 1 to 3 jettisoned at an altitude of 88 km
T+00:00:03:16 FAKE Abort tower jettison at an altitude of 90 km and velocity 2.03 km/s

#Artemis #NASA #SLS
T+00:00:05:24 SRB splash down in Atlantic RIP noisy rockets. that worked

#Artemis #NASA #SLS
T+00:00:08:03 MECO (main engine cutoff), altitude 157 km, orbit 30 x 1808 km
T+00:00:08:15 #SLS separate from #ICPS/#OSA/#Orion in 30 x 1808 km orbit.
