Launch controllers were forced to abandon their second attempt this week to launch a crew capsule into lunar orbit with test dummies after NASA's new moon rocket sprung another hazardous fuel leak on Saturday. The first flight has been postponed for several weeks or perhaps months.
The 322-foot (98-meter) Space Launch System rocket, the most potent rocket NASA has ever developed, was previously attempted on Monday, but that attempt was also plagued with hydrogen leaks, albeit on a smaller scale. This was in addition to leaks found earlier in the year during countdown drills.
