hit another snag on Wednesday morning after a leak like the ones that had delayed previous launch attempts.
"Teams warmed up the quick disconnect umbilical line and the leak then maxed out at 3.4%, which is within the acceptable range to continue," the team said. "The pre-pressurization test will bring the core stage liquid hydrogen tank up to the pressure level itwhile engineers calibrate the settings for conditioning the engines at a higher flow rate, as will be done during the terminal count on launch day," NASA said in a blog post.
