SpaceX • Falcon 9 Block 5 • Space Launch Complex 4E (CA)
Fourteenth batch of satellites for a reconnaissance satellite constellation built by SpaceX and Northrop Grumman for the National Reconnaissance Office to provide imaging and other reconnaissance capabilities.
Live targets are highlighted across the sequence.
On Friday, June 19 at 1:50 a.m. PT, Falcon 9 launched the NROL-179 mission from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base in California.
This was the third flight for the first stage booster supporting this mission, which previously launched two Starlink missions. Following stage separation, the first stage landed on Landing Zone 4 (LZ-4) at Vandenberg Space Force Base.
There was the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may have heard one or more sonic booms during the launch, but what residents experienced depended on weather and other conditions.

Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.

This outlook evaluates whether a broad, sunlit ascent plume could stand out. It does not yet predict whether a specific vehicle will produce one, and a no-jellyfish call does not mean the rocket itself will be invisible.
