[Launch Alert] Sunday Launch

[Launch Alert]

The following is an advisory from Vandenberg SFB:

"Vandenberg Guardians and Airmen are scheduled to support the launch of NASA's Sentinel-6B mission aboard a SpaceX Falcon 9 rocket Sunday, November 16, from Space Launch Complex 4 East (SLC-4E) from Vandenberg Space Force Base.

Liftoff is targeted for 9:21 p.m. PT.

Following stage separation, the first stage will land on Landing Zone 4 (LZ-4), which will create a sonic boom local to the base.

The live webcast will begin approximately one hour before Falcon 9's liftoff at plus.nasa.gov.

Sentinel-6B will use radar to bounce signals off of the ocean surface to deliver continuous ocean topography measurements. The mission also will collect high-resolution vertical profiles of temperature to assess temperature changes in Earth's atmosphere and improve weather prediction models. It will take over from Sentinel-6 Michael Freilich, a twin of Sentinel-6B, which Falcon 9 launched five years ago on November 21, 2020.

There is the possibility that residents of Santa Barbara, San Luis Obispo, and Ventura counties may hear one or more sonic booms during the launch, but what residents experience will depend on weather and other conditions."

Weather permitting, the launch could be visible to the unaided eye over a wide area.
