NASA's SLS delays due to Hydrogen leak
On Saturday, September 3rd, NASA's Space Launch System (SLS) rocket began fueling up for its second attempt at launching Orion around the Moon on the Artemis I mission. During initial fueling of the Liquid Hydrogen (LH2) tank on the core stage, there was an over pressure event in one of the lines that caused fuel flow to stop automatically. After this, there was a consistently large LH2 leak coming from the umbilical when switching from slow fill into fast fill that would stop fueling again.
