                         LAUNCH ON SCHEDULE

Thursday evening's airborne launch of a NASA satellite off of
California's Central Coast is on schedule. A Pegasus XL rocket
carrying NASA's IRIS satellite is targeted for launch at 7:27:34 p.m.
PDT during a 7:25:04 to 7:30:04 p.m. PDT launch window.

Note that the launch and launch window times are for the original
Wednesday evening launch attempt. They are probably little changed
(accurate to within 20 seconds) for Thursday's launch attempt.
