The competition heats up: ULA will attempt its third Atlas 5 launch in October, launching a new GPS satellite for the Air Force on October 30.
In the past ULA never packed its launches in this tightly. I suspect they are now doing so because of the competition from SpaceX. They need to show their customers, both commercial and the government, that they are a reliable launch provider. Launching three Atlas 5s in one month is one way to do it.
