The NROL-85 mission is scheduled to launch from Vandenberg Space Force Base aboard a SpaceX Falcon 9 rocket on Friday, April 15.
NROL-85 is the second partnership between SpaceX and the National Reconnaissance Office (NRO) this year.
It will be the first NRO launch to reuse a SpaceX Falcon 9 rocket booster. The plan is to reuse the same SpaceX Falcon 9 rocket booster used in the February NROL-87 launch.
Following the launch, the rocket's first stage will return to land on Landing Zone 4 at Vandenberg Air Force Base.
People from Ventura to San Luis Obispo counties may hear several sonic booms as the vehicle breaks the sound barrier upon re-entry.
