The launch will begin a long-delayed flight to propel an unmanned Orion crew capsule around the Moon and back.
If more strips of "RTV" insulation break free during the Space Launch System rocket's ascent into space, an engineering analysis has shown that the material is not as massive or dense,
With the countdown moving into its final hours, NASA's mission
management team unanimously approved the third launch attempt to be moved to 1:04 a.m. EST Wednesday, opening a two-hour window
The 322-foot-tall Space Launch System rocket, NASA's most powerful rocket ever,
But the first SLS to roll off the assembly line has been plagued by hydrogen fuel leaks and other glitches,
This has interrupted multiple fuel tests and two launch attempts since the vehicle was launched last March to launch pad 39B more than 240 days earlier.
After coming up with "kinder, gentler" technology to fuel the rocket to minimize any leaks,
engineers prepared for another launch attempt on November 3,
