Scrub Briefing Targets 9:30 start

The post-scrub briefing is targeted for 9:30 p.m. EDT on NASA TV. STS-128 Launch Director Pete Nickolenko and mission management team Chairman Mike Moses are scheduled to address the postponement of the launch of Discovery. The Wednesday morning launch attempt was scrubbed when a problem developed with a fill-and-drain valve inside the shuttle’s aft compartment.
