Guiana Space Centre

The Guiana Space Centre also called Europe's Spaceport is a French and European spaceport to the northwest of Kourou in French Guiana, a region of France in South America. Operational since 1968, it is particularly suitable as a location for a spaceport. It fulfills the two major geographical requirements of such a site:

It is near the equator, so that less energy is required to manoeuvre a spacecraft into an equatorial, geostationary orbit. Rockets launch to the east to take advantage of the angular momentum provided by Earth's rotation.
