Folks in southern California will have an opportunity to see the last Titan IV launch out of Vandenberg in about an hour, at 11:04 AM Pacific time. If the sky is clear, go outside and look to the west. Spaceflightnow is blogging the countdown.

[Update a couple minutes later]

To clarify, it’s the last Titan IV (or Titan anything) launch, period. It just happens to be launching out of Vandenberg. And with its retirement, Delta IV can take over as reigning pad queen.

I don’t know if it was the Transterrestrialanche, or what, but SpaceFlightNow is now down.

Well, it apparently launched, but I didn’t see it. There was a slight marine layer, and it may have obscured the view.
