I seen over at dslreports.com that they are showing according to Worldwide launch Schedule that DirectV 11 is now scheduled for a December 2007 launch date.

Edit (Tom Robertson): Current Launch time is scheduled for 6:48 ET on March 19. Expected to be on DIRECTV channel 573.

Perhaps not the first posting here. :) Must be time to create a generic D11 thread.

Cheers,

I know that this has been posted before but I am sure many, including new members have not see this link.

It answers all the questions about number of transponders, national, spot and spare.

Because it is a Sea Launch located on the equator my understanding is that the time required to park D11 in its assigned slot is much less than from launches located far from the equator like D10 launched from Baikonur Cosmodrome located at Latitude 45°57'48. Maybe it will cut off two to three weeks compared with the D10 setup time - that might mean that it will be production ready by the end of January 08.:hurah:

We can only hope for now!

Ohh OP i saw that thread over at dslreports. Man they are all D* bashers there. If there are any talk of satellite TV they attack. I cant begin to tell you how many time HD lite was mentioned and people there say D* sucks.they arent too fond of E* over there either. STUPID CABLE LOVERS!

Their loss.

As to the orbital mechanics issue, yes. Equatorial launches into equatorial orbits take less delta-V (and hence fuel) than do orbits from non-equatorial locations. The further off the equator the launch site from the inclination of the target orbit, the higher the fuel or mass hit. If you follow the ISS program, part of what has extended the assembly sequence was inclusion of the Russian space program. A Progress or Soyuz spacecraft cannot be launched with much usable mass into the original planned station orbit, which was much lower inclination to coincide with the latitude of Kennedy Space Center (roughly 28.5 degrees N). Since the current ISS has a much higher inclination to allow Russian launches (51.6 N) the shuttle takes a 10,000-pound-plus hit to its launch mass capability).

By contrast, launching from the equator allows for a higer-energy transfer orbit that does not require much more than tweaking in terms of the orbital inclination, and since launch mass is generally higher, you can use more fuel and make your final GSO faster.

Complicating this is the fact that there are two different launch vehicles involved, of course. Zenit is not Proton/Breeze and vice versa. I don't know off-hand what the maximum launch mass to GTO is for Zenit, but I'm sure a basic spec is available on the SeaLaunch site.

Sea Launch didn't blow up, the rocket engine (used in other launchers as well) did. Sea Launch was mostly cleared of any part of the issue. (I suspect there were small little procedural improvements made as there would be after any major inspection.)

Tom

As Tom points out, the booster exploded but SeaLaunch as a company pretty much didn't do anything wrong. However, you have to understand the nature of SeaLaunch:

They are an international joint-venture between Boeing (who helps do payload integration), a Russian company (which provides the Block upper stage and engines for the booster, a Ukrainian company (which provides the majority of the booster itself), and a Norwegian company that provided the launch platform and infrastructure. So, to be blunt, there's a lot of places where things could go wrong simply given the number of organizations that have to accurately exchange information.

In the case of the failure early this year, the fault was traced to metallic debris in the LOX turbopump, though I have yet to see any indication of what that debris was or was thought to be. It could be a broken internal weld, a sensor element that fractured and was carried through the lines until it jammed in the pump, or even a foreign object left in the tank during manufacture or test. SeaLaunch probably knows but isn't saying, so far as I've seen.

Anyway, as an aside, despite the "Really Cool Idea!" aspect of launching from an equatorial platform, SeaLaunch has had some significant teething troubles. They have a much higher failure rate than any of the major competitors in the commercial launch business (with the exception of SpaceX, who is not yet really major at all). Of course, the statistical sample size is so small at this point as to be of questionable value in making an usable estimate like that.

EDITED TO ADD: It took a minute to find it, but here's the writeup on SeaLaunch and the Zenit booster from Astronautix.com (a VERY comprehensive spaceflight encyclopedia, by the way. Highly recommended).

A number of them also love UVerse. Mention that the system can do only 1 HD stream at a time and they jump all over you, who needs HDTV, what a waste of money, etc. Wonder if they're still using rotary phones since they were too cheap to get touch tone?

See post My Setup for configuration info.

I still have a pulse dial line :D (with a 5meg dsl on it) :hurah: saves $2.43 a month..

Who do you have that still charges for TT service, didn't know they were still doing that? When I was auditing bills for work at home staff I haven't run across anyone still doing that. Just curious.

It's an old service.. they used to give a credit for it (2.43) and I just haven't changed it since I got it.. Now days they don't even offer it.. I still think it's funny that they give me a discount for a line they have to maintain a "interpreter" on.. And yes it will ignore a touch tone signal.. I just throw the switch on all my phones when I buy them :)

I think most of us can agree that the dslreports people are jserks. I cant imagine how many times i stuck up for D* in there before and got bashed. UVerse HA! thats a joke..thats At&T's 2bit competition to FiOS..and its nothing but VDSL thats not even close to FTTH.

Yeah and if your not gettin yelled at with the HD argument, then they say "Oh well you have HD lite and youll always have it!" Then i'd say tell me that in September when we have MPEG4 with whatever amount of HD we want and more channels than you while you still can only watch one at a time.

Id get Uverse for the internet being i cant get FiOs in At&t territory.....and cable isnt here for internet. But the TV HA! the only good feature is that if you only have one box in the house you can use Quad Tuners for the DVR and remote DR functions that we will hopefully soon get.

Does anyone think that with FiOS and DBS taking cable customers every day in the (kinda far)future that cable will be internet only?

WOW this server is always too busy whenever i pot!

Sea Launch Awaits Delivery of new Gas Deflector
http://www.sea-launc.../nr_070723.html

"Long Beach, Calif., July 23, 2007 – Sea Launch’s prime contractor for launch system ground support, the Design Bureau for Transport Machinery (DBTM) of Moscow, Russia, has completed fabrication of a new gas deflector for the Zenit-3SL launch system. The massive structure is expected to arrive in mid-August at Sea Launch Home Port, where it will be installed at the stern of the Odyssey Launch Platform, beneath the launch pad.

The gas deflector was destroyed during the failed January 30 launch attempt, when a Zenit-3SL vehicle lost thrust and impacted the structure. The gas deflector (also known as the flame deflector), is a one-of-a-kind, 280 metric ton steel structure, including truss supports, that directs engine exhaust away from the platform and controls the acoustic environment. DBTM managed construction of the replacement structure near the Baltisky shipyard in St. Petersburg, Russia, where the original deflector was manufactured.

Sea Launch is proceeding on schedule with repairs and re-certification of the Odyssey Launch Platform and associated launch support equipment. A team of specialists currently working on the Odyssey at the Victoria Shipyard in British Columbia, expects to complete the heavy industrial repair work and painting next week.

The construction of the gas deflector is considered a major milestone among these activities. Other completed work includes repair and installation of the platform’s hangar doors and communication antennas, and replacement of heat-affected wiring and cables. Sea Launch plans to conduct marine tests before returning to Home Port in Long Beach in August to resume work with the installation of the gas deflector. Progress of “Mission Recovery” is posted on the Sea Launch website at www.sea-launch.com. Following repairs and recertification of all systems, the Sea Launch team will transition to mission operations in preparation for the launch of the Thuraya 3 satellite in October"

It does seem like there are a lot of companies and countries involved with Sea Launch. It sounds like you have a better chance of a good launch with Borat :lol: Sorry I just had to say that one more time :blush:
