    Curious why they chose that route, since SeaLaunch has been so successful for them to date...

    Well they launched Directv 5 & 8 so I guess Directv bids it out to see who is cheapest for that particular launch or can handle their time frame.

    Also D10 was Proton (ILS).

    In fact, D10 was the last Proton launch before a failure. :eek:

    Interestingly, the failure turned out to be caused by the Briz-M upper stage; the new configuration for the new generation of very heave comsats requires a whole series of lengthy burns to get inclination down to zero while at the same time raising the orbit to GSO. Anyone else remember the crazy ground tracks from D10 when it looked like the satellite was doing figure 8's and zig-zags over the globe? Expect another flurry of posts based on "information" from web-based "tracking" sites. :D

    But in any case, that upper-stage configuration resulted in a thermal stresses on the upper stage and engine because of the long burns required for such massive payloads, resulting in failure. They have since successfully returned to flight and there are several other launches between now and then which should help them gain continued operational and flight confidence in the revised designs since the last failure.

    It's just nice to know now that D* actually does have a place in line to get D12 launched.

    Great information Sixto. How long before launch does Diretv have to get orbital location authority for D12 or do they already have an approved location. How does that work?

    Tried to get the orbital location info but no luck. :) Not available yet ...

    Also no news during the usual Friday FCC filing ...

    yep, but the question has been which launch provider/vehicle and which slot (99/101/103).

    we've known about the launch for a while now.

    I thought folks have been saying that the current Ka/Ku LNB's that have been installed don't do Ka from 101. Would they really want to have to go back out and swap LNB's after the last round of upgrades?

    yep, 101 is unlikely.

    but remains on the list until we hear for sure ...

    All the speculation was SeaLaunch. Recent credible report says 2009 ILS/Proton.

    Hasn't been any official posting anywhere. All sites still say TBD.

    Actually most sites still speculate to Sea Launch.

    No info on slot.
