Are all polar sat's launched from Equatorial pads? Why would they have to do that? Facilities , and its warmer LOL. Note they are not taking any advantage of rotation, I merely said that a polar orbit launch from the equator would give the orbiter a rotational movement around the globe, if the earth indeed had movement. I suspected a launch from the pole would not have such shifting, and thus should remain on the same longitude.. If the earth continued to spin beneath it, then this would appear, I said "appear" to support a rotating earth... Any mony to build a launch facility on the South pole anybody? Philip.
