NASA currently waiting on winds at KSC to lessen to begin rollout of Artemis II back to LC-39B.

It was scheduled to begin movement earlier tonight but high winds has prevented them from starting.
 
An explanation for the reasoning behind Terafab. You’ll need to read the tweet in full, it only shows the top portion below. tldr; Kardashev scale.
 

Really hope we can colonize the moon in my lifetime. If we dont, China will. That episode of Space Force where the Chinese and US troops have a little skirmish and destroy eachothers gear may be reality if we dont get our stuff together and get it done. We have to win Space Race 2.

Wonder who chose "doo doo brown" for the color scheme on that thing? Build a brazillion dollar rocket but cant spring for a decent color?
It is the color of the insulating foam applied to the exterior of the tank. It is required because of the slow fill rate of the tanks and the fact that NASA has it sitting on the pad fully fueled for several hours leading up to the launch.
The SpaceX approach with Starship however is to rapidly fuel the rocket starting just over 30 minutes prior to launch which means it doesn’t need extra insulation to avoid boil off.
The insulation used on SLS is the same type used on space shuttle launches. If you look at videos of early shuttle launches, you will see that the external tank was pained white. After a few launches they stopped painting it to save weight and you wound up with the orange/brown that we see today.

My bet is that the Russian cosmonauts were setting up a clandestine vodka distillery. 😀
