Engineers have just doscovered another issue with Discovery that is being addressed at this time. A backup circuit breaker that controls the primary heaters on the segment joints of both solid rocket boosters has failed. A team called “Red Team” will be going out to the mobile launcher platform to quickly replace the circuit breaker and then leave. This isn’t a mission threatening problem as Discovery could fly with only the main circuit breaker functioning, but since there is the time to replace the failed unit, the team will do so.
The latest weather update suggests that there is upwards of an 80% chance of a clear launch window today.
