A new leak in the same line that caused that scrub was detected as NASA halted liquid hydrogen fueling shortly before 10 a.m. The 7% leak is above the 4% threshold NASA has in place for cryogenic fueling limits. NASA then shifted to problem solving using the same warmup procedure it had tried several times in previous leak detections. The fix worked to some degree with operations on both cryogenic fuels up and running so that by noon, the liquid oxygen was approaching 100% of its 196,000-gallon capacity.Read Long Article
