Spacex has once per month launch schedule but targeting twice per month

Spacex has an aggressive launch schedule for 2015. They are going to try to launch about once per month. They plan to ramp to twice per month launches

The Spacex manifest of upcoming missions does not include the planned dates

The Christian Science Monitor notes how Spacex is 12 years old but still has the agility and spirit of a startup company. Spacex is also close to being certified for big defense contract missions.
