JOHN F. KENNEDY SPACE CENTER, Fla.—NASA scrubbed a lunar-orbit launch set for Monday due to technical glitches, a fresh hurdle for the space agency as it looks to prove its most powerful rocket ever can handle planned missions to the moon.
The National Aeronautics and Space Administration said engineers need time to resolve problems related to temperature and pressure in one of the four engines installed on the main part of the Space Launch System rocket. The space agency halted the countdown clock at one point Monday, and officials said they may again try to launch Friday pending further analysis.
