The rollout of the first Space Launch System rocket had slipped to the middle of February. NASA said Wednesday that it replaced a controller in one of the four engines in the core stage of the rocket and is conducting tests of that computer and other vehicle systems before rolling the rocket out to the launch pad in mid-February for a fueling test and practice countdown known as a wet dress rehearsal. NASA has not set a date for the launch of the SLS on the Artemis 1 mission, but a rollout in mid-February means a launch is unlikely until at least later in the spring.
