METOP launch Monday -- unusual trajectory

Jim Oberg wrote: Launch is set for Monday -- take a look at the unusual ascent trajectory, and follow the plot out a few more thousand miles.... Unless it's hiding behind some of the stupid Flash nonsense, I didn't see a trajectory plot... In any case, the description and the orbital elements are consistent with a launch toward a 95.4-deg inclination -- one of the standard Baikonur-Soyuz inclinations -- plus a bit of yaw steering by the Fregat stage to reach 98.7. Not a path Baikonur uses every week, but not anything especially new and strange. -- spsystems.net is temporarily off the air; | Henry Spencer mail to henry at zoo.utoronto.ca instead. | |

METOP launch Monday -- unusual trajectory
Get a string and a globe and seat-of-your-pants take a gander at
the first rev ground track, and it IS unusual in terms of WHOM it goes right over the head of. "Henry Spencer" wrote in message ...

Not a path Baikonur uses every week, but not anything especially new and strange. "The launcher trajectory will be north-west - heading towards Svalbard and north Greenland." ... I suspect that means "north and a bit west". The northern ends of Svalbard and Greenland are just above 80degN, in about the right places for a straightforward launch from Baikonur to a 98-99deg orbit to cross them. Could the true original information have had not north-west (315 deg) but north north west (in which Turnpike's spelling checker would like to "correct" the repeated word) (337.5 deg) or north by west (348.75 deg)... Either of those is at least roughly plausible. -- spsystems.net is temporarily off the air; | Henry Spencer mail to henry at zoo.utoronto.ca instead. | |

METOP launch Monday -- unusual trajectory
"Jim Oberg" wrote Launch is set for Monday -- take a look at the unusual ascent trajectory, and follow the plot out a few more thousand miles.... Today's planned launch of a European weather satellite, on a Russian rocket, that would have passed directly over central United States, has been cancelled due to a fuelling problem about one hour before blast-off. They may be able to try again tomorrow. The exact path across North America is southwards over winnipeg, Denver, El Paso then over Mexico. I.E., almost direrctly over Cheyenne Mountain, home of the North American Air Defense HQ. Fortunately, they are aware the never-before-used flight path is entirely peaceful. No startling surprises. |

MetOp launch for Tuesday has also been been cancelled. This gives one more chance on Wednesday 19th at the same time of day.

Baikonur has done sun-synchronous launches before, although possibly not at this *exact* azimuth. -- spsystems.net is temporarily off the air; | Henry Spencer mail to henry at zoo.utoronto.ca instead. | |
