If all goes according to plan, here are the approximate milestones:
Broadcast starts: 1:15PM
Bunch of boring interviews until t-0:15 or so
Launch at 1:31PM
MaxQ: 1:32PM
1st Stage separation: 1:33PM
2nd Stage separation: 1:36PM
Payload faring separation 1:37PM
3rd Stage separation: 1:41PM (launch broadcast will probably end around this time)
Breeze Burn 1 (raise to initial parking orbit): 1:42-1:50PM
Breeze Burn 2 (increase orbit altitude): 2:39-2:56PM
Breeze Burn 3 (increase to Geosynchronous transfer orbit phase 1): 4:59-5:08PM
Fuel tank jettison (yay space junk!): 5:09PM
Breeze Burn 4 (increase to Geosynchronous transfer orbit phase 2): 5:11-5:19PM
Breeze Burn 5 (remove most of the inclination to bring the orbit closer to the equator): 10:25-10:30PM
Separation: 10:43PM
Should find out if all went well around 11PM EST.
