You'd think at 8,000 miles an hour a few cross winds at high altitude @ 40-50mph wouldn't be a problem.

Google Translate:
"Last Update: Le Gall, Arianespace CEO wants to manifest themselves already at 19.45 clock." Doesn't moke much sense, but one interpretation is the CEO wants the crew ready for a "go no go" by 45mins past the hour (local time). They are up & going.............again

Look what happened to poor old Challenger when she was hit by severe low altitude cross winds |

I remember one of those Ariene 5's blowing up shortly after launch years ago. Hopefully Astra will soon deploy correctly & we could then be in for some nice FTA gifts for Christmas

![]() The film insert says Astra 1N should be in service at 28E in mid September, although I reckon thats a bit optimistic |

Some interesting facts from last night. 1N will use half of its fuel getting from its current GTO to GSO.
The danger from high altitude winds is that launch debris can be blown back on to populated areas; nothing to do with impacts on the vehicle which is supersonic shortly after liftoff. |

What I want to know, and Analoguesat can probably tell us, is how long is it before 1N reaches it's GSO from GTO? I presume it's something like 5hrs (from snippits of info on Wikipedia)? |

Also there did not seem to be any change in launcher characteristics for the change in 1N location and it seems to be up to the customer to move his satellite into the required orbital position, wherever that may be. |
