Range costs definitely are the greatest costs involved in getting to low earth orbit:

Private Rocket Heads for Island

The privately-built Falcon 1 rocket has experienced yet another hiccup in getting off the ground. The maiden flight of the booster is being slipped to later this year due to a range conflict at the Vandenberg Air Force Base in California. Furthermore, the delay has meant the rocket’s premier flight is being moved to the Kwajalein Atoll.

Falcon 1 is built by Space Exploration Technologies Corporation (SpaceX) of El Segundo, California, an effort bankrolled by entrepreneur Elon Musk. The booster went through an on-the-pad hot fire test of its engine May 27, bolstering hopes the rocket would take to the air in August from its Vandenberg Air Force Base launch pad.

But in a short statement on the SpaceX website: “We were just informed that the Titan 4 flight will launch no earlier than September and may very well be delayed until October or November.”

Since Falcon 1 is required to launch after the classified flight of the Titan 4, SpaceX said its first launch “will now be from our island launch complex in the Kwajalein Atoll” in the western Pacific Ocean.
