ORIGINAL STORY - SpaceX is targeting the early morning of Friday, June 19, for the launch of the classified NROL-179 mission aboard a Falcon 9 rocket from Vandenberg Space Force Base.
The 35-minute launch window opens at 1:40 a.m. on Friday.
This mission marks the third flight for the Falcon 9's first-stage booster, which will attempt a landing back at Landing Zone 4 nearly eight minutes after liftoff.
If you're in Santa Barbara, San Luis Obispo, or Ventura counties, you may hear one or more sonic booms as the booster returns to Earth, depending on weather conditions.

According to base officials, the mission carries a national security payload designed, built, and operated by the National Reconnaissance Office.
