Falcon 9 launched early Monday morning

UPDATE (7:16 a.m.): Falcon 9 has successfully launched. 

Several minutes into its flight, the first stage booster -- with its job done -- aimed for a touchdown at the Cape Canaveral Air Force Station. SpaceX strives to return most of its first-stage boosters for reuse.

This was the fourth SpaceX booster landing at Cape Canaveral, even more have landed on an ocean platform. 

UPDATE (6:50 a.m.): SpaceX has tweeted that the launch is a go and now set for 7:15 a.m.

Aerospace company SpaceX plans to launch their Falcon 9 rocket early Monday morning. 

Falcon 9 was previously set to launch early Sunday morning, but the launch was scrubbed due to a sensor issue in the first stage booster.  

The rocket will send one of its launch vehicles into space from the Space Coast and will carry a spy satellite for the National Reconnaissance Office.

This launch is also the first time SpaceX is doing business with the U.S. Department of Defense.
