Discovery Delayed Until...?

According to an article at CNN, the launch of Discovery is going to be delayed until at least Saturday. According to an article at the BBC, however, the launch has been delayed until at least Monday. NASA's Return to Flight page agrees with the CNN page, that the next chance for a launch is Saturday. Either way, all this really means is that they're not sure what is going on with the sensor, and where the problem lies exactly. It may lie in the sensor itself, which would require moving the shuttle back to the VAB to fix. The problem may lie in the wiring to the sensor, a problem which can be fixed while it's on the pad, or the problem may lie in the telemetry FROM the sensor, another problem that can be fixed while the shuttle is on the pad. Hopefully by tomorrow they'll have a better idea of what the problem is exactly, where it is, and how to fix it, and a new launch date and time will be announced.
