    I'm hoping there's no debris to dodge. :grin:

    Only the normal stuff: fairings, boosters, gases, etc. I'm hoping D12 is a clean, happy launch and short trip to home on Lagrange. :)

    So, you propose to ditch the sat to Lagrangian point ;) ? Far away from GSO 103W !

    Assuming that W7 goes well and on schedule ...

    Assuming that D12 is contracted to follow W7 ...

    Assuming that the time between launches follows past patterns ... (last time I analyzed this I think the average was about 42 days)

    Then I'd say 12/31 with up to 10 days prior or 10 days after as a range.

    Well, you forgot about 'clear window' - space debrie and other launches are very significant contributers to establising the date.

    I would seriously dispute the idea that space debris is a significant issue with regard to scheduling launches. Other launches using the range, yes. As I've said many times in this thread, launch range availability is very, very important factor. That usually revolves around how often and for how long authorities can reasonably clear the areas downrange for staging events (no one wants a spent rocket stage to fall on them, let alone one filled with nasty hypergolics). It also depends on the tracking, telemetry and command/control data handling capabilities of the range facilities.

    I wouldn't - just ask those ppl who are tracking it and providing tons of numbers to heads of ILS and launching crew how important it is.

    I used to work with people doing it for NASA and I'm still in contact with some of them. Debris is not a major launch constraint (unlike range limits).

    Boeing needs to correct their website... It shows that the national payload is Ku, not Ka.... At least it shows the spots are Ka. If its going to be a late December launch, then maybe Santa could pull D12 and put it into orbit with that sleigh of his:lol::lol::lol::lol: Come on Rudolph, Full power......

    Still significant and definitely taking in consideration of time a launch.

    It's about 75th on the list of most important launch constraints. :rolleyes:

    The Boeing site says 2009.

    The CFO recently said 2009.

    Anik says 2009.

    Other indications lean towards 2009.

    My gut feel is that the internal (non-public) schedule has a date in 2009.

    Might it slip? Sure. Happens all the time, with weather or any number of other scheduling items.

    But as long as it is within a little bit of 12/31, we'll be golden by the end of Q1/2010.

    May I see the mentioned list ? ;)

    Anyway it still there regardless of the position and really counted. C'mon LL - I pointed to that and you did too already. Lets move to watch Moffett strip :).

    Sorry, I can't disseminate "Sensitive But Unclassified" stuff without losing access to it. :)

    MY point is that debris considerations might affect a launch window to within a few minutes, not within a few days or weeks. Remember, the Briz-M is going to perform nearly half-a-dozen post-launch burns and then D12 itself will spend weeks tweaking its own trajectory.

    OK.

    You'll let us know (after that launch will happened when nobody will harm by disclosure) what was a major and minor point in that decision of particular day/hour/minute of liftoff.
