OK, thanks for the information everyone, I think I can put the puzzle pieces together and picture the relationships.

Funny thing is I'd just found the aero.org website yesterday while doing some totally unrelated research. Anyway, some great resources there and i was wondering "just who are these people?" and now I know.

Thanks.

Realigned the thread for Friday's attempt. Will realign the article a bit later, once everyone on different timezones get to notice it was scrubbed last night.

No that is not correct, they were indeed selling tickets for this launch to view from the Saturn V Center and have done that for several recent launches since the shuttle ended (and sold tickets for the causeway for GRAIL).

In Jim's defense, that is KSC not CCAFS, NASA launches have causeway ticket viewing.

If I understand correctly, cloud they can handle - it's high-velocity cross-winds at high altitude that were the problem yesterday.  I have seen Deltas, Protons and Arianes vanishing into 100% cloud cover almost right of the pad.

It depends on what kind of cloud, a repeat of AC-67 is not desired.

...oddly, FLTSATCOM was a direct ancestor of MUOS.

I want a Saturn V for Christmas, Only a Saturn V will do,
I don't want a Falcon 9, no dinky Delta IV,I want a Saturn V to launch with and enjoy

William Graham's overview updated for the second attempt - if you've not read it yet, so it now. 4,000 worder.

The Russians, in particular, seem willing/able to launch into pretty terrible conditions. A product of necessity, given the climate in most of their launch facilities, I guess!

In regards to the AC-67 failure, the issue was with the formation of lightning.  The launch constraints state the following: "The flight path of the vehicle should not be through middle-level cloud layers 6,000 feet or greater in depth, when the freezing level is in the clouds." At Baikonur, the freezing level is kind of a moot point during the cold season since it's below 0 Celsius at any altitude... basically it's difficult to compare the weather on the Eastern Range with Kazakhstan because they are very different, but it does make for some interesting "blast-off in a blizzard" pictures!  :)

Ha, Disney! ;)

So far it's on for tonight. Weather is a bit tougher for this attempt, remember - but as they say, it's Florida and it's hard to predict what it'll be like at T-0.

Rain stretches well to the west of the KSC area and clouds will continue to thicken as the wet weather approaches. Certainly looking worse than yesterday from a cloud/precip perspective.

T-120 minutes. Going down to the T-4 minute hold. Weather will be the concern.

Excellent article--thanks Messers Bergin and Graham.  I see the SRMs are carried for an additional (approx) 14 seconds after burnout--is this to facilitate disposal in a safe place?  I know this is an issue for launches from VAFB, but didn't think it would be so off the FLA coast.
