How firm is the date: Go for launch (confirmed by the provider)
Date history: No date change recorded for this launch.
At the pad when the window opens: Daylight launch. The sun is up at the pad. You see the rocket and its exhaust trail; the engine flame is less vivid than at night, and from far away a day launch can be hard to pick out.

Plan a trip: every Vandenberg launch in your dates

What to expect

We have not checked this mission's landing plan by hand. If a booster flies back to a landing zone on land, its landing brings a sonic boom; the provider's mission page says where the booster lands.
Sound travels about a kilometre every 3 seconds (a mile every 5), so at a distance you see liftoff before you hear it.

Will it go on time?

A launch date is a "no earlier than" target. Weather, a technical hold, the range or a boat in the hazard area can each stop a count on the day, and the provider then names a new time. We do not publish launch odds we cannot back; here is what we recorded.

8 launches have flown from Vandenberg since we started recording date changes on Aug 29, 2026; 7 of them had the date or time moved at least once after we first recorded it, and 1 slipped by a day or more. That is too few launches to call it a rate.
Of the 34 launches that have flown from every site we track since we started recording date changes on Aug 29, 2026, 21 (62%) had the date or time moved at least once after we first recorded it, and 5 (15%) slipped by a day or more.
