Engineers are hopeful the weather will cooperate for the planned launch Saturday of NASA's Artemis moon rocket.
If all goes well, engineers will begin pumping 750,000 gallons of cryogenic liquid oxygen and hydrogen fuel into the Space Launch System rocket at 6 a.m. EDT Saturday, setting up a launch attempt at 2:17 p.m., the opening of a two-hour window.
A detailed post-scrub data analysis confirmed the engines were, in fact, receiving the correct thermal conditioning, a requirement to prevent possible bearing damage when powerful turbopumps begin spinning up for takeoff. Likewise, a post-scrub analysis showed a crack in the core stage spray-on insulation, likely caused by thermal stress during fueling Monday, did not pose any significant risk to the rocket.
