SpaceX sent an advisory Wednesday warning that this launch could trigger a sonic boom, which residents of Brevard, Orange, Osceola Seminole and Volusia counties may experience. Hearing the sonic boom will depend on weather conditions across the region.

The new nine-engine rocket will launch from pad 39A and will take the secret payload to a low orbit. Falcon 9 rocket will return to Landing Zone 1 at the Cape Canaveral Air Force Station. Prior to this mission SpaceX has landed the first stage booster at Landing Zone 1 seven times.

The Zuma mission will be SpaceX's 17 launch this year.

The engines were ignited for testing purposes early Saturday evening at NASA’s Kennedy Space Center. This is a customary step in all SpaceXlaunch campaigns.

Cumulus clouds could be the main restrictions for the launch, which is given a 70 percent chance of being a “go."
