NASA’s new moon rocket sprang another dangerous fuel leak Saturday, forcing launch controllers to call off their second attempt to send a crew capsule into lunar orbit with test dummies.
Mission manager Mike Sarafin told journalists it was too early to tell what caused the leak, but it may have been due to inadvertent over-pressurization of the hydrogen line earlier in the morning when commands were sent to the wrong valve.During Monday’s attempt, a series of smaller, unrelated hydrogen leaks popped up in the rocket.
Mission managers accepted the additional risk posed by the engine issue as well as a separate problem: cracks in the rocket’s insulating foam. But they acknowledged other problems -- like fuel leaks -- could prompt yet another delay. That didn’t stop thousands from jamming the coast to see the Space Launch System rocket soar. Local authorities expected massive crowds because of the long Labor Day holiday weekend.
