Today, NASA began a fueling test of the Space Launch System core and upper stage
at Kennedy Space Center, which might clear the way for the Artemis I.
The test at Launch Pad 39-B is designed to ensure that repairs to fuel lines made during a scrub on September 3
can handle the more than 730,000 gallons of cryogenic liquid hydrogen and liquid oxygen.
a second leak in the same line that caused the scrub was discovered after NASA terminated liquid hydrogen fueling soon before 10 a.m.
The 7% figure is higher than the 4% maximum set by NASA for cryogenic fueling.
"As soon as the flow was stopped, the leak rate immediately decreased," Nail explained.
