A simulated ignition of Discovery's Number 3 engine yesterday yielded no problems; the only unusual thing found was a tiny foreign particle on a cable connector. Due to the inconclusive troubleshooting, NASA has decided that it would be more time efficient to replace the entire engine. On Monday, the Number 3 engine will be replaced with the engine that used to be Discovery's Number 1 engine until it, itself, was replaced last month due to a now-fixed loose fuel pump thermal shield. NASA plans to reschedule the launch next week, with 16 and 18 July being considered as possible launch dates.
