Before this last (and successful) launch attempt, NASA was doubtful if the rocket would take off. The launch crew noticed a leak on the liquid hydrogen refill valve on the launch tower, and it required some time to tighten the bolts surrounding it. Furthermore, the US Space Force had to repair the radar that was supposed to follow the rocket’s launch when it went down unexpectedly. Finally, the ground team was able to repair the hydrogen leak, and Space Force discovered that the radar problem was caused by a faulty Ethernet switch.
