The following is an announcement from Vandenberg SFB:

"The U.S. Space Force has approved the launch of a SpaceX Falcon 9 rocket carrying the Starlink 17-35 mission to low-Earth orbit, Sunday, April 5, 2026, between 4:03 p.m. – 8:03 p.m. PT from Space Launch Complex 4 East (SLC-4).

A live webcast of this mission will begin about five minutes prior to liftoff, which you can watch at https://www.spacex.com/launches/sl-17-35 and on X @SpaceX. You can also watch the webcast on the X TV app.

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."

If the launch occurs in daylight, the orange flame from the first stage could be visible to the unaided eye up to 100 statute miles from the launch pad and either side of the Falcon's flight path. The vehicle should also briefly produce a white vapor trail during the early portion of the first stage burn. The second stage burn will probably be invisible. If liftoff happens after sunset, the event could be visible for several minutes over a wide area.

For a better view of the launch, use tripod-mounted binoculars or a spotting scope. An astronomical telescope with a low-power eyepiece will probably provide the best view.
