Clock reset to T-45 minutes.

As we wait for the launch team to debrief, we should note that this launch has a 3-hour launch window.
(1400-1700 UTC = 9:00 am-12:00 noon Eastern Standard Time)

Depending on the issue, they may be able to fix the problem and launch before the window closes.
If they start from the T-45 minute hold, they have until 11:15 am EST.

Or launch during same window tomorrow.

EDIT: Same announced in web cast.

Looks like they'll be trying to recycle today. Vehicle and payload are in good condition.

Team still trying to determine if they can recycle today. Don't have a new T-0 yet.
