CAPE CANAVERAL, Fla.—NASA aimed for a Saturday launch of its new moon rocket, after fixing fuel leaks and working around a bad engine sensor that foiled the first try.
The inaugural flight of the 322-foot (98-meter) rocket—the most powerful ever built by NASA—was delayed late in the countdown Monday. The Kennedy Space Center clocks started ticking again as managers expressed confidence in their plan and forecasters gave favorable weather odds.
