SLS likely facing another launch delay
Engineers for NASA’s SLS rocket have determined that they need to replace the flight controller on one of the engines in the rocket’s core stage, an action that will likely force a delay from the presently scheduled February launch date.
After performing a series of inspections and troubleshooting, engineers determined the best course of action is to replace the engine controller, returning the rocket to full functionality and redundancy while continuing to investigate and identify a root cause. NASA is developing a plan and updated schedule to replace the engine controller while continuing integrated testing and reviewing launch opportunities in March and April.
It appears they hope to make this change-out quickly and only have to delay one or two months, though at the moment it is also unclear this will be possible.
