Uh oh... Mystery... :)

After mentionning Thursday before, now I read this :
" 4/20/2010 - VANDENBERG AIR FORCE BASE, Calif.  -- The launch of a Minotaur IV spacelift booster is delayed due to forecasted weather.

The rocket was set to launch from Space Launch Complex-8 on south base Tuesday, April 20, 2010. The launch has been rescheduled with a time frame of noon-6 p.m. Wednesday, April 21, 2010. "

Re-alinging William's article for the latest attempt. We'll need to keep an eye on the above link in case of another delay.

Still no word on any webcast?

And the coincidence with X-37B launch is more than enough to freak the nuts, it's semi-freaking ME....   ;->

No sign of a webcast from what we can see, Jim.

Maybe somone in California wants to take a trip over and feed a webcam into a LiveFeed hosting program? :)

Do you guys have one of those LiveFeed backpacks with the six EVDO cards in it for doing Flash Media Encoding and uplink from anywhere?  If so, I think I can find someone out here to be your launch cameraman :  )

So we don't know the exact launch time? Usually VAFB tightens up the launch window a little bit for launches like these when we get closer to the launch.  Seems like the NOTAMS restrictions for a six hour launch window would be semi-ridiculous...

That is the window. It doesn't have to reach a specific orbit (or any orbit for that matter), so it isn't dependant on the position of the Earth, Sun and other spacecraft relative to the target orbital plane at the time of launch. Minuteman tests also have long windows.

Right, I'm with you on the lack of need to reach a specific orbital plane.  I'm just surprised that they didn't tighten up the window more than they did given the effect that it has on the range during daylight hours.

A longer window gives them a better chance of resolving problems, or waiting for weather to improve.

Having been to Vandenberg, unless you're on base, the closest you're going to get is to the south.  And it's possible that they have evacuated some of the southern beach areas depending upon launch safety concerns (although I doubt it).  Viewing from the east isn't all that great.

So unless you're right there, the best you're going to get is a smoke trail.

I've managed to find places to see launches of vehicles I worked on, when I wasn't on base for the launch... But yes, you are at long range.

Hopefully I'll be there watching one I supported take its ride in July...

Nothing on the VAFB site about a launch yet.

They powered down Minotaur and are doing a recycle to T-70. Which should pickup in about 30 minutes. Very cloudy here but no word on weather.

Minotaur is Green, HTV is Green, weather is Amber? (What ever that means) Weather downrange is Green. Picking up count in about 5 minutes for a 4:00pm local launch.
