New Soyuz Launch Facility Near the Equator 127
tcd004 writes "Russian and French teams are currently hard at work in French Guiana on the northern coast of South America, building the first Soyuz launch facility in the Western Hemisphere. Soyuz rockets normally carry 3,500 pound payloads into orbit, but from the French Guiana spaceport, the rocket will have an added benefit of being near the equator where the Earth's spin makes launching slightly easier. This extra boost allows Soyuz to deliver a 6,600 pound payload into orbit. The first launches are scheduled for October."

The inclination is crazy high because the russians only had a site at something like 45 degrees (roughly as far north as Wisconsin).
There are two separate effects:
1) The closer you are to the equator the more mass you can boost because the equator is spinning rather quickly... obviously about a timezone per hour...
2) Out of inclination launches are possible, but they waste tons of fuel. You can launch into any inclination orbit from any latitude, it just costs a ton of fuel.

Not quite.
