Review after aborted first launch of uncrewed ship finds problem was only a faulty sensor, not cooling system or engine itself
Nasa will make a second attempt to fly its pioneering Artemis 1 moon rocket on Saturday afternoon after the US space agency declared it had identified and fixed an engine issue that caused the postponement of the original launch attempt five days earlier.
Mission managers at the Kennedy Space Center in Florida called off Monday’s liftoff with 40 minutes left on the countdown clock when a sensor indicated one of four RS-25 engines on the core stage of the mega Space Launch System (SLS) rocket was not cooling properly.
