The countdown to launch Ares I-X picked up at T-7 hours beginning at 1:00 a.m. EDT on Wednesday.
Liftoff of NASA's first Constellation Program development test flight is targeted for 8:00 a.m.
The weather, which ultimately resulted in NASA scrubbing yesterday's attempt, is expected to be slightly better today. There is predicted to be a 60 percent chance of weather conditions being favorable during the launch window, which extends until noon.
Today's countdown will proceed much along the same schedule
as yesterday's attempt, with the exception of the removal of the five hole sensor cover. The velcro-attached protective sock was removed from the 327-foot rocket's nose instrumentation on Tuesday and was not designed to be reinstalled between attempts.
