    Can't say I blame them. I get paid to design mission-critical server infrastructure here on the ground, and having spares around is super-duper important. One of the things we've done is to convince the major hardware vendors to keep spare parts on-site in our building -- basically making us a mini parts depot. Guess the sat guys are thinking the same thing, just on a different scale!

    Conditions aren't very much the same out in the Clark Belt. The temperature conditions are pretty stable and the line power is all in-house. Most servers couldn't be happier if they were twins in conditions like that.

    Middle...
    Temperature of a vacuum that high is a null concept. And spacecraft temperatures are NOT constant at all, thanks to the 24-hour orbital period and equatorial inclination. That, and the occasional solar flare or random cometary micrometeoroid fragment, make GSO a somewhat less hospitable environment than you indicate. An orbital spare is a very good thing.

    (Did I ever mention I used to design spacecraft environmental control systems for a living?)

    And there is the subliming of materials over time. Didn't that cause the whisker effect prematurely ending the lives of several satellites?

    Thanks, Lamelefty,

    Tin whiskers [tin = bad..gold = good].
    This was "known" forty years ago, but "lead = bad", so whiskers came back without it.

    You guys are starting to go over my head with all of this sat tech talk (not to say that's not too difficult to do :lol: )

    June is getting awfully close. I imagine we'll learn of the actual launch date in the next week or so maybe?

    I don't if we'll learn a launch date this week, but I'm expecting news soon... (Good, of course--the glass is ALWAYS full, just sometimes there is some air in there too...)

    Cheers,
    Tom

    I don't recall seeing a link to this page - it is the official website of the KHRUNICHEV STATE Research and Production Space Center - the people that manufacture the Proton Launch Vehicle - it also lists the next launch as June for DIRECTV 10.

    anik's list was updated today. One of the end of May Dnepr launches has been given a date of May 30 and the other slid to June. The Dnepr rockets launch from a completely different setup than do the Proton-M rockets.

    DirecTV 10 is still just June.

    A very interesting read is the ILS Proton Mission Planner's Guide. It gives very detailed information on the facilities along with typical timeline.

    Amazing. The "NEXT" launch. Hopefully, it will be up soon.

    anik's list was updated again today. Most notable is that Sirius 4 has gone to TBD status which opens the window a lot wider for a launch anywhere from June to early August.

    If I had to guess, I'd be betting on Boeing be significantly behind schedule as they are building both DirecTV 10 and Sirius 4.

    I hope it stays sometime in June like we've been anticipating.

    This is great news that is very welcome here in my home. I hope that we see some of the talked about HD National Channels like National Geographic HD and NFL Network HD.

    And just for reference sake, does anyone out there know approximately how long it takes for the satellite to go live after launch?

    Lyngsat.com finally updated D10 to show June. (Actually, its been there before and is now again.) D11 is also still showing June at Lyngsat, but they do have the correct launch vehicles now.

    Cheers,
    Tom

    ILS has posted info saying that their last launch, the ANIK F3, went into service this past tuesday.

    http://www.ilslaunch.com/stories/anikf3/inservice/

    That's just 22 days from launch to activation.

    I know they are different sats but hopefully DirecTV 10 will get up and running quickly after it's launched.

    Wishful thinking. I hope you're right on that assumption. I'm guessing D10 will have a faster turnaround time than the Spaceways that launched last year since D10 won't have several spotbeams to aim correctly.
