Arianespace Ready for Liftoff 93
stuckinarut writes to tell us Arianespace is reporting that their newest Ariane dual-satellite ECA mission rolled out of the assembly building and is set for a launch today (Nov 12) at 2345 GMT. This flight is set to demonstrate the massive lift capacity of nearly 10,000 kg and is currently the "only commercial vehicle that can launch two mainstream telecommunications satellite payloads on the same mission."

With government-funded rocket systems the world over, development costs are not factored into launch costs. Launch costs on the Ariane 5 EC-A are over 10k$/kg, with a full payload at that. Yes, the more frequently you launch, the cheaper the price per kg; however, it doesn't come close to just

So, for instance, in Business Studies class, we strictly meant 10^9 if we used the word billion, but in English class, the meaning was much more ambiguous.
Since the mid-seventies, officially a billion has meant 10^9 in government documents in Britain, Ireland and elsewhere, but its old meaning as 10^12 has remained colloquially. (I left secondary school in 1999, which is fairly recent and it was still possible to use the 10^12 form then).

I certainly was surprised to see this show up on the front page of slashdot. It's not a super big deal that Ariane is launching two satellites at once, they have done that before. I guess the capacity has increased from the sounds of it? One of the satellites onboard (Spaceway F2) will be one of the largest commercial satellites ever launched. It's sister satellite, Spaceway F1, was launched last April and was successfully delivered to the DirecTV customer this fall. They are both about 6100 kg when fully loaded with fuel.
Companies may be able to save some money by doing a dual-manifest launch but it can also be a real pain in the ass. This launch was originally supposed to happen in June but the other satellite had problems and had to get sent back to home base to be checked out thus delaying Spaceway F2 also. Plus when you get your own launcher you can have a lot more control over what orbit you are injected into and the launch window. Ariane provides a standard GTO injection with their ECA launcher, which is not the most desireable orbit for some satellites.

First of all, the shuttle doesn't launch things to GTO because it itself cannot go to GTO. It launches things to LEO and then the satellites themselves will boost their orbit to GTO, and finally to geosynchronous orbit.
Second, three satellites is no big deal either. For on flight V165, an Ariane 5 launched not one, not two, not three but 7 satellites. Granted one of them was a nano-satellite that weighted only 20kg. Likewise,

Under the agreement, the Russian agency will manufacture Soyuz rocket parts for ESA, which will then be shipped to French Guiana [cia.gov] for assembly. ESA benefits because it gains a medium payloads launcher, complementing its fleet [esa.int] while saving on development costs. In addition, the Soyuz rocket -- which has been the Russian's space launch workhorse for some 40 years -- is proven technology with a good safety record, which ESA might be happy to use for launching humans into space.
