The launch was previously scheduled for Friday morning, but was delayed to allow teams to complete pre-launch data checks and reviews, SpaceX said on Twitter.
After launch, SpaceX will again attempt to recover the first stage of the Falcon 9 rocket used in the mission by landing it at the Central Coast base. The rocket will be used in future missions.
This mission will mark the first time a previously used rocket booster will be used for a National Reconnaissance Bureau launch. The rocket was used in a reconnaissance satellite launch in February, also from Vandenberg.
