      NOTE: Launch managers postponed the launch of Space Shuttle Columbia today for 24 hours due to unacceptable local weather conditions. No significant technical issues were worked during the countdown and all Shuttle and payload systems remain in excellent health.

      The KSC launch team is executing a 24-hour scrub turnaround that will have Columbia and Chandra in a posture to launch at 12:24 a.m. Friday. Shuttle managers will convene at noon today to finalize the launch window for tomorrow's launch attempt.

      Weather officials are currently indicating a 30 percent probability that weather could prohibit launch on Friday. The primary threats are thunderstorms, rain showers and anvil clouds.
