The Kennedy Space Center clocks started ticking again as NASA preps for a redo of the scrubbed launch.
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.
Atop the rocket is a crew capsule with three test dummies that will fly around the moon and back over the course of six weeks — NASA’s first such attempt since the Apollo program 50 years ago. NASA wants to wring out the spacecraft before strapping in astronauts on the next planned flight in two years.NASA Administrator Bill Nelson said he’s more confident going into this second launch attempt, given everything engineers learned from the first try.
“We have convinced ourselves without a shadow of a doubt that we have good-quality liquid hydrogen going through the engines,” said John Honeycutt, the rocket’s program manager. The engine-temperature situation adds to the flight’s risk, as does another problem that cropped up Monday: cracks in the foam insulation of the rocket. If any foam pieces break off at liftoff, they could strike the strap-on boosters and damage them. Engineers consider the likelihood of that happening low and have accepted these slight additional risks.
