Time's a rabbit were here to help you grab it.

The new regulator has been installed successfully at the pad. Leak checks are underway now.

NEW LAUNCH TIME. Liftoff is being shifted back by 10 minutes to 4:19 p.m. EST. Those 10 minutes are being inserted into this current hold in the countdown, giving the pad crew additional time to finish the bad purge regulator removal and replacement.  That's toward the end of the window, so if any other weather related delays occur...scrub time.
