Welcome to the Satellite Industry. If Space was easy... Everyone would do it.
Starting to look like a real possibility of only 2 SpaceX launches this year. 6 Launches originally scheduled, moving for the need for 15 launches in 2014, and 7 launches in front of the first scheduled NEXT Space X launch. So that will be 22 launches in 20 months from a company that appears can only do two launches a year at this juncture. Cassiope just went TBD along with the rest of the scheduled 2013 launches. One launch failure and the first SpaceX launch could be in 2017 or 2018. Then it will be time for another bedtime story when they tell you they expect commercial availability thru 2021 out of the existing constellation. I hear engine qualification tests in Texas this next week. If so,then that puts the first v1.1 launch in October at the earliest.
