So, how many satellites are in those retrograde-polar orbits? *** None ... they are in a Polar Orbit. Hmmmm... there could be reasons for a real retrograde orbit. I'm not an expert, but I seem to recall that Israel would have to use a retrograde orbit for any satellites they put up from their own land. If the launched to the east (in the direction of enemy nations) it would initially be seen as a missile attack on those nations - and if the launch was a failure and things came down from the sky on those nations, even more so. There could be immediate retaliatory strikes. So their only reasonable launch path would be to the west over the Mediterranean Sea, i.e. retrograde. Of course, maybe they could rent launch facilities from a nation that had them (some friendly nation with facilities with ocean to the east). But in general I don't think Israel would want to be dependent on other nations for something that would involve their own national security. Hitching a ride to the Space Station, sure, not a problem. But having someone else launch their own spy satellites would be something quite different. They might consider the extra cost to boost in "the wrong direction" well worth it to have everything under their complete control. |
