NASA cancels second Artemis launch to the moon amid stubborn fuel leak

A NASA rocket made another dangerous leak Saturday, as the launch team began fueling it for liftoff on a test flight

For the second time this week, the launch team began loading nearly 1 million gallons of fuel into the 322-foot (98-meter) rocket

Which is the most powerful rocket ever made by NASA. Monday's attempt was called off due to a bad engine sensor and leaking fuel.

As the sun came out, an over-pressure alarm sounded and the tanking operation was briefly halted, but no damage was done.

And the effort resumed, but a few minutes later, hydrogen fuel began to leak from the engine section at the bottom of the rocket.

NASA halted operations while engineers scrambled to plug what was believed to be a gap around a seal in the supply line.

The countdown clocks continued ticking toward an afternoon liftoff; NASA had two hours Saturday to get the rocket off.
